Legal notes

Warning note conceptThis manual comprises notes which must be observed for your personal safety and for preventing materialdamage. Notes for your personal safety are marked with a warning triangle, those only for preventingmaterial damage appear without a warning triangle. Depending on the level of hazard, the warning notesare shown in reverse order of seriousness, as follows.

DANGERmeans, that death or serious injury will result, if the appropriate preventive action is not taken.

WARNING

means that death or serious injury may result, if the appropriate preventive action is not taken.

CAUTION

means that a slight injury may result, if the appropriate preventive action is not taken.

NOTICEmeans that material damage may result, if the appropriate preventive action is not taken.

Where there is more than one hazard level, the warning note for whichever hazard is the most serious isalways used. If in a warning note a warning triangle is used to warn of possible personal injury, a warningof material damage may be added to the same warning note.

1.5 Measuring-surface sound-pressure level

The gear unit has a measuring-surface sound-pressure level at a distance of 1 m, which can be found intables 4 to 6.

The measurement is carried out to standard "DIN EN ISO 9614" Part 2, using the sound-intensity method.

The workplace of the operating personnel is defined as the area on the measuring surface at a distanceof 1 metre in the vicinity of which persons may be present.

The sound-pressure level applies to the warmed-up gear unit at input speed n1 and output power P2 statedon the rating plate, as measurement obtained on the Siemens test bench. If several figures are given, thehighest speed and power values apply.

The measuring-surface sound-pressure level includes add-on lubrication units, if applicable. Withoutgoing and incoming pipes, the flanges are the interfaces.

The sound-pressure levels stated in the table were obtained by statistical evaluation by our Quality ControlDept. The gear unit can be statistically expected to comply with these noise levels.

4.3 Storing the gear unit

The gear unit must be stored in a sheltered place in the position of the original packaging or in the positionof use, placed on a vibration-free, dry base, and covered over.Gear units with grease-lubricated rolling bearings must be stored in the position of use.

NOTICE

Material damage

Any damage to the coating may cause failure of the exterior protective coating and thus corrosion.When temporarily storing the gear unit and any single components supplied with it, the preservativeagent should be left on them.Ensure that the coat is not damaged.

DANGER

Danger to life through tilting or falling gear unit

Risk of being squeezed or killed by a tipping or falling gear unit.Do not stack gear units on top of one another.

NOTICEMaterial damage

Damage to the gear unit through build up of a layer of foreign bodies or moisture. If the gear unit is beingstored out of doors, it must be particularly carefully covered, and care must be taken that neither moisturenor foreign material can collect on the unit.Waterlogging must be avoided.

NOTICE

Material damage

Damage to the gear unit through external sources.Unless otherwise agreed by contract, the gear unit must not be exposed to harmful environmental factors

such as chemically aggressive products.Provision for special environmental conditions during transport (e.g. transport by ship) and storage(climate, termites, etc.) must be agreed by contract.


28/111

28 / 111BA 5038 en 01/2014

4.4 Standard coating and preservation

The gear unit is provided with an interior preservative agent; the free shaft ends are painted for protection.

The characteristics of the exterior coat depend on the ambient conditions stipulated in the order relatingto method of transport and area of application.

NOTICE

Material damage

Damage to the gear unit possible through corrosion.The gear unit is normally delivered completely ready, with a priming and a finish coat.Where gear units are delivered with a priming coat only, it is necessary to apply a finish coat inaccordance with directives applying to the specific application.The priming coat alone is not suitable to provide a sufficient long-term corrosion protection.

NOTICE

Material damage

Damage to the shaft seals possible.When doing cleaning work and/or applying the top coat, the shaft seals must be protected with suitablemeans (e.g. sealing with adhesive tape).

This protection prevents paint or cleaning media from getting into the gear unit and coming into contactwith the shaft seal.

Note

The coating complies with the requirements for the conductivity of the coating and the limitation of thelayer thickness of the applied coating in accordance with standard "DIN EN 13463-1". The permissiblemaximum coating thickness depends on the indicated explosion group (IIA or IIB or IIC). Where coatingshave a thickness < 200 µm, no electrostatic charge is to be expected.

DANGER


Danger to life through ignition of any potentially explosive atmosphere through electrostatic discharge.The coating must not carry an electrostatic charge.The operator must ensure that highly effective mechanisms which can set up a charge in the coating aresafely avoided.

Note

Examples of highly effective charge-generating mechanisms are:

– the rapid passage of heavily dust-laden air near by

– the sudden escape of particle-laden compressed gases

– other heavy friction action (not manual cleaning or rubbing with cleaning cloths)


Any damage to the coating may cause failure of the exterior protective coating and thus corrosion.Ensure that the coat is not damaged.


29/111

29 / 111BA 5038 en 01/2014

Note

Unless otherwise agreed by contract, the interior preservation is guaranteed for 6 months, and theexterior preservation for 24 months, provided that storage is in dry, frostfree sheds.

The guarantee period starts on the date of delivery or that of the notice that the item is ready for shipment.

For longer periods of storage (> 6 months) we advise regular checking and, if necessary, renewal of theinterior and exterior preservation (see items 7.4.1 and 7.4.2).

The output shaft must then be rotated at least one turn to change the position of the rolling element in thebearings. The input shaft must not be in the same position as before rotation.

This procedure must be repeated and documented every 6 months until start-up.

Note

The record must be kept with these instructions.

4.4.1 Interior preservation with preservative agent

Note

Depending on the operating oil (oil type and viscosity), as indicated on the rating plate, the gear units

have been preserved with the preservative agent specified in table 7 or table 8.

5. Technical description

Observe the instructions in section 3, "Safety instructions"!

5.1 General description

The gear unit described is a "FLENDER gear unit" designed for driving agitators in the chemical industry.

The gear unit is supplied as a two-, three- or four-stage helical and/or bevel-helical gear unit. It is designed

for installation in a vertical position. If necessary, it can also be designed for installation in a differentmounting position.

In case of types H.AV, H.BV, B.AV and B.BV the output shaft is rotating in an oil-dam pipe. This preventsgear oil from escaping at the shaft end. The oil supply takes place by a flanged-on pump or by a motorpump.

NOTICE

Material damage

Destruction of the gear unit or gear-unit components possible through incorrect direction of rotation.The gear unit can be operated in both directions of rotation.However, it is possible that a certain direction of rotation has been specified in the order which is realisedby adding-on a backstop or an overrunning clutch.

The gear unit is characterised by a low noise level. This is achieved by bevel and helical gears with a highcontact ratio and a sound-damping housing.

The good temperature characteristics of the gear unit are achieved by its high degree of efficiency, largehousing surface and performance-related cooling system.

A number of shaft configurations (types and rotation directions) are possible. These are shown in thefollowing table as solid shafts. The arrows with the direction of rotation show the correlation between thedirections of rotation of the input and output shafts.

5.2 Housing

The housing is made of cast iron; if necessary, it may also be made of steel.

Housings up to size 12 are made in one part. The sizes 13 to 26 have a two-part housing. The housing isof torsionally rigid design and because of its shape imparts very favourable noise and temperaturecharacteristics.

The gear-unit housing comes with the following equipment:

─ Lifting eyes (adequately dimensioned for transport)

─ Inspection and/or assembly cover (for oil filling and/or inspection).

─ Marked oil-filling position with screw plug (for oil filling).

─ Dipstick with MIN and MAX marks (for checking the oil level).

─ Oil-drain plug and/or oil-drain cock (to drain the oil).

─ Air filter (for aerating and bleeding).

5.3 Toothed components

The toothed components of the gear unit are case-hardened. The helical-gear teeth are ground. The highquality of the teeth leads to a significant noise reduction of the gear unit and ensures safe and reliablerunning.

The gear wheels are joined to the shafts by interference fits and parallel keys. These types of joints transmitthe torques generated with adequate reliability.

5.4 Lubrication

5.4.1 Splash lubrication for gear units without oil-supply system

When installed vertically, all teeth and bearings are submerged in oil. The extended space required(for expansion of the oil) is provided by an oil-equalising tank bolted-on.


37/111

37 / 111BA 5038 en 01/2014

5.4.2 Force-feed lubrication by add-on flange oder motor pump

The gear units of the series H.AV, H.BV, B.AV and B.BV are generally equipped with a force-feedlubrication.

The gear units of type H..V from size 13 onwards are equipped with a force-feed lubrication. Dependingon order requirement, sizes 7 to 12 can in special aplications also be fitted with force-feed lubricationand/or from size 13 onwards with splash lubrication.

The force-feed lubrication system system is permanently attached to the gear unit and consists of a flange

or motor pump, a coarse filter, a pressure-monitoring device and related pipework. For gear units of sizes13 to 26, the coarse filter is replaced with a double change-over filter.

The direction of flow from the flanged-on pumps is independent of the direction of rotation. In exceptionalcases a flanged-on pump dependent of the direction of rotation can be used. Related specifications canbe taken from the drawings in the gear-unit documentation and the list of equipment.

5.5 Shaft bearings

All shafts are fitted in rolling bearings.

5.6 Shaft seal

Radial shaft-sealing rings, Taconite seals or special seals at the shaft outlets prevent oil from escapingfrom, or dirt from entering into the gear unit.

5.6.1 Radial shaft-sealing rings

Radial shaft-sealing rings are the standard type of seal. They are fitted preferably with an additional dustlip to protect the actual sealing lip from external contamination.

NOTICE

Material damage

Destruction of the radial shaft-sealing ring possible through high dust concentration.Do not use radial shaft-sealing ring in an environment with high dust concentration.

For special mounting positions the radial shaft-sealing ring is used with a grease filling in combination witha ring.Where large quantities of dust occur in accordance with the conditions permitted under Directive 94/9/EC,use is possible only in combination with the Taconite seal (see item 5.6.2).

Fig. 22: Radial shaft-sealing ring

5.6.2 Taconite sealTaconite seals have been especially developed for use in a dusty environment. The entry of dust isprevented by the combination of three sealing elements (radial shaft-sealing ring, lamellar seal andgrease-charged, re-chargeable labyrinth seal).

41/111

41 / 111BA 5038 en 01/2014

5.6.3 Oil-dam pipe

By sealing the downward pointing input shaft with a contact-free and wear-free shaft seal (a so-called"oil-dam pipe") the shaft outlet is sealed absolutely tight to prevent oil escaping. This system is used onlyfor force-feed lubrication.

The lower anti-friction bearing of the output shaft is separated from the gear-unit interior by the oil-dam pipeand is lubricrated by grease. Grease is prevented from escaping by the use of a radial shaftsealing ring.


Risk of damage to the lower bearing through insufficient sealing.The relubrication intervals must be observed for relubrication of the lower bearing (see section 7,"Startup", and table 26 in section 10, "Maintenance and Repair").

5.7 CoolingDepending on requirements, the gear unit is fitted with a fan, a cooling coil, an added-on oil-supply systemwith water oil-cooler / air oil-cooler or a separately provided oil-supply system. In case of use of a separateoil-supply system, the specific operating instructions for this oil-supply system must also be observed.

Note

The oil-supply system must have been designed and manufactured for use in accordance withDirective 94/9/EC.

Note

When fitting the gear unit free convection must be ensured on the housing surface, in order to definitelyavoid overheating the gear unit.


42/111

42 / 111BA 5038 en 01/2014

5.7.1 Fan

As a rule the fan is fitted on the high-speed shaft of the gear unit and is protected from accidental contactby an air-guide cover. The fan sucks air through the grid of the air-guide cover and blows it along the airducts on the side of the gear-unit housing. It thereby dissipates a certain amount of heat from the housing.

NOTICE

Material damage

Overheating the gear unit possible through insufficient air feed.For gear units fitted with a fan, sufficient space must be allowed for air intake when mounting the safetyguards for the coupling or other components.The correct distance is given on the dimensioned drawing in the gear-unit documentation.It must be ensured that the air-guide cover is correctly fastened. The air-guide cover must be protectedagainst damage from outside. The fan must not come into contact with the air-guide cover.

NOTICE

Material damage

Overheating of the gear unit possible because a layer of dirt on the gear unit or dirty air filter is having aninsulating effect.The cooling effect is considerably reduced if the fan and the housing surface are dirty.Observe instructions for cleaning in section 10, "Maintenance and repair".


43/111

43 / 111BA 5038 en 01/2014

5.7.2 Cooling coil

The gear unit can be fitted with a cooling coil in the oil sump. Cooling water is supplied to the cooling coilby way of a water connection. The operator must ensure this. Either fresh water, sea water or brackishwater can be used for cooling purposes.

When water is flowing through the cooling coil, a certain amount of heat is transferred from the oil to thewater and thereby removed from the system.

5.7.3 Add-on oil-supply system with air oil-cooler

For all types, an oil-supply system with air oil-cooler may be applied. This oil-cooling system is permanentlyattached to the gear unit.

Components:

─ Air oil-cooler

─ Flanged-on pump

─ Coarse filter (from size 13: double change-over filter)

─ Pressure monitor

─ Temperature-control valve

─ Pipework

The air oil-cooler is designed to cool the gear oil by means of air from the surrounding atmosphere.Depending on the volume flow, the oil passes through the cooler in one or more streams and through thecurrent of ambient air blown in by the fan. For cold starts, a bypass pipe with a temperature-control valveis provided for.

Note

The flow direction of the flanged-on pump used is independent of the direction of rotation, if nothingis specified in the documentation to the contrary.When connecting the fittings the actual flow direction must however be observed.

Note

The operation is monitored by a temperature monitor in the oil sump or by a pressure monitor.For control information, refer to the list of equipment.The operating instructions for the device must be observed.
