INTORQ I Spring-applied brake INTORQ BFK459

The BFK459, especially developed for the asian market, is positioned between the BFK457 and the BFK458. The BFK459 has the same mounting dimensions as INTORQ's standard BFK457 and BFK458 series, and its geometry is based on the BFK458 series.

The main components of the new modular system are the two basic modules E (adjustable braking torque) and N (non-adjustable braking torque). The basic modules can be combined with modular components to achieve maximum flexibility for a wide area of application.

friction plate

Basic module N with manual releaseINTORQ BFK459 spring-applied brakes are single-disc brakes with two friction surfaces. At zero current, several compression springs are used to generate the braking torque through friction locking. The brake is released electromagnetically. During braking, the compression springs use the armature plate to press the rotor (which can be shifted axially on the hub) against the counter friction face. When the brakes are applied, an air gap is present between the armature plate and the stator. The stator's coil is energised with DC voltage in order to release the brake. The resulting magnetic flux works against the spring pressure to draw the armature plate over the air gap to the stator. The spring pressure exerted on the rotor is thereby released and it can rotate freely.

The torque adjustment ring can reduce the braking torque so the customers can adjust it.

Technical data

Braking torques

The basic modules E and N are available in the graduated torques listed below. A pole shim (brass film) must be placed between the stator and the armature plate if you want to achieve short engagement times at low torques. INTORQ brakes are dimensioned so that the specified rated torques can usually be achieved reliably after a short running-in period. However, as the organic friction linings used do not all have identical properties and because environmental conditions can vary, deviations from the specified braking torques are possible. These must be taken into account in the form of appropriate dimensioning tolerances. Increased breakaway torque is common in particular after long downtimes in humid

environments where temperatures vary. If the brake is being used on friction surfaces provided by the customer, the rated torque must be checked. If the brake is to be used solely as a holding brake without dynamic load, the friction lining must be reactivated at regular intervals.

The rated torque on version E can be reduced by unscrewing the torque adjustment ring.

The operating times listed in the tables apply to switching on the DC side with rated air gap, standard braking torque and warm coil, and they assume that switching is controlled by INTORQ rectifiers. The operating times of the

brake vary dependent on the selected braking torque, how worn the brake is and the temperature. The engagement time t1 for AC switching is higher than that for DC switching by approximately a factor of 10.

❙ 1) The DC switching times were obtained using a spark suppressor,

which limits the coil voltage on opening to 800 V.

Technical data

Service life and wear

The amount of friction energy to be withstood until sLmax (maximum permissible working air gap) is reached and the brake is adjusted depends on various factors. These include in particular the mass to be decelerated, the differential speed, the operating frequency and the resulting temperature at the friction surfaces. Therefore, it is not possible to specify a friction energy value until readjustment that is universally valid for all operating conditions.

In addition, increased wear should be expected with vertical mounting.

The BFK459 can be adjusted when sLmax is reached. The way in which the friction lining is dimensioned allows the brake to be adjusted at least 5 times.

Where the amount of friction energy per switching operation is low, the brake's mechanical components can impose limitations in terms of service life. The rotor/hub connection, springs, armature plate and sleeves are particularly vulnerable to operational wear. The expected service life of the standard design is around 1 million load alternations. Solutions that are optimised in terms of service life are available in cases where a longer service life is required (consult the supplier).

MaintenanceBrakes are components that are subject to wear. Easy access for inspection and maintenance work must be ensured. Intervals between inspections should be set in accordance with the expected service life and load. For more information, please see the operating instructions.

Torques dependent on speed

For the BFK459 series of brakes, a friction lining with a with low rate of wear is a standard feature for all sizes.

The following table lists the braking torque as a percentage in relation to speed.

Thermal load limits

The permissible operating frequency Shperm depends upon the switching energy Q. The defined operating frequency Sh results in the permissible switching energy Qperm.

Wear increases at high speed and switching energy due to the very high temperatures prevailing at the friction surfaces for short periods of time. The stated values are restricted by the load limits of the friction lining.

Wear values and permissible friction energy

The wear values in the table are valid for the low-wear friction lining and standard braking torque during

operation at mains voltage. Remember that an increase in torque will reduce wear reserves!

Accessories

Noise-reduced aluminium rotorThe rotor with the plastic sleeve reduces the necessary backlash to a minimum and thus increases the service life.

Manual release The manual release is used to release the brake by hand and can be retrofitted. The springs (3) ensure that the release returns to its original position automatically after operation. An additional air gap S is required for the manual release function; this is factory-set. The size of S (see the mounting instructions) needs to be checked once the manual release has been fitted.

Accessories

FlangeA flange can be used in the absence of a suitable counter friction face. Furthermore, a cover ring can be mounted on the flange.

Friction plateA friction plate is available for sizes 06 to 16 inclusive. The plate should be used if, despite being smooth and machined, the counter friction face is not suitable for use as a friction surface. The plate can be combined with a seal.

Microswitch (Sizes 12/14/16)The brake can be fitted with a microswitch for the purpose of monitoring the release function. The microswitch can be integrated into the switching arrangement as an NC or NO contact.


Accessories

SealThe seal, which slots into the designated groove on the stator, all but excludes the possibility of dust, humidity, dirt, etc., entering or exiting the brake chamber. In the absence of a suitable groove on the counter friction face, we recommend the use of a flange or a friction plate.

Universal spark suppressor INTORQ-14.198.00.0ò

The universal spark suppressor limits the induction voltages generated when switching off inductive DC loads on the DC side. As these induction voltages can damage coils and switches, VDE 0580 requires that users take suitable protective

measures in order to avoid impermissibly high opening voltages and overvoltages. The universal spark suppressor is available in 4 designs for the following voltage ranges:

Dimensioning

Basics

+ ML = To be used when lowering a load, for example

– ML = For normal braking operation

A brake is dimensioned essentially on the basis of the required braking torque Mreq.The inertias to be braked (moment of inertia), the relative speeds, the braking times and the operating frequencies must be included in the calculations. Knowledge of basic conditions such as ambient temperature, air humidity, dust levels, etc. is required, and the mounting position must also be known. In the case of extreme/critical operating conditions, please contact the manufacturer. Dimensioning compliant with VDI Directives 2241.The friction surfaces must be kept free from oil and grease at all times. The terms used in the calculation are explained in the list of abbreviations on page 5.

Safety factorIn order to achieve the required safety even under extreme operating conditions, the calculated braking torque needs to include the safety factor K, the value of which should be set dependent upon the operating conditions.

Load typesThe following load types are primarily encountered in practice:

Mreq = Ma · K & MK

Mreq = (Ma ± ML ) · K & MK

Mreq = JL

· ∆n0 ± ML · K & MK

Dynamic and static loadMost applications involve a mixed load, given the presence of a dynamic load in addition to a static load torque.

P · K & MK ∆n0

Estimating the required braking torque and/or sizeIf only the drive power to be transmitted is known, the required torque or braking torque can be determined as follows:

Thermal loadIf high operating frequencies and friction energy/switching cycles are to be expected, we recommend recalculating the thermal data for the brake. The friction energy per switching cycle is calculated as follows:

– ML = To be used when lowering the load, for example+ ML = For normal brake operation

The permissible friction energy per switching cycle at the given operating frequency can be taken from the diagrams on page 15. If the friction energy per switching cycle is known, the permissible operating frequency can also be taken from these diagrams.

Thermal recalculation

Calculated switching energy Q = 4792 J/switching cycle.For size 14 at Sh = 6 h-1, the diagram on page 15 shows a permissible switching energy of 30,000 J.

Q = 4792 J < Qperm = 30,000 J
