MACHINE PARAMETERS

Module range 0,1 – 2 mm

Center distance range for basic slide 16,5 – 90 mm

Vertical stroke 50 mm

Diameter of measured gear, max. (clamped on arbor) 120 mm

Diameter of measured gear, max. (clamped between centers) 80 mm

Weight of measured gear, max. 0,5 kg

Measuring force adjustment (manually adjustable) 0 – 8 N

Measuring accuracy up to 1 μm

Standard master gear arbor diameter 12,7 mm

Dimensions 350 x 200 x 200 mm


MEASURING PRINCIPLE

• Tooth errors cause deviation of axis distance

• Left and right flank is measured simultaneously

• Constant force in radial direction

• Measuring accuracy is better than 1 μm

• Deviation according to DIN, ISO, AGMA, JIS, JGMA and BS


SMALL AND VERY SMALL GEARS

• Manufacturing requirements:

• Quality grade according to DIN standard

• Guaranteed tooth backlash

• Low running noise

• Influence of assembly accuracy

• Localization of tooth nicks

• Quick and inexpensive measurement

This is all where our double flank gear tester canhelp you

SOFTWARE INTERFACE

Basic parameters of toothing, description of clamping fixtures

Measuring software isuser-friendly requiring no special PC knowledge. Itcan communicate in many languages and runs underMicrosoft Windows operation system.


TOLERANCES

Option of standards and a degree of accuracy for each deviation


EXAMPLE 1: GOOD RESULTS

Double flank chart, gear with 36 teeth

• Radial runout about 0,010 mm

• Visible meshing of individual teeth

• One tooth in the middle of chart is little thicker


EXAMPLE 2: TOOTH NICK

Tooth No.9 is damaged on top

• Gear has axial runout


EXAMPLE 3: LOW QUALITY GEARING


• Wrong pressure angle

• Tooth No. 5 is damaged or dirty


EXAMPLE 4: LOW QUALITY GEARING


➢ Radial runout

➢ Teeth have inaccuracy of profile from hobbing machine


EXAMPLE 5: MEASURING OF BACKLASH

• Axis distance is evaluated according to given value

• Calculation of measurement over teeth or over pins


EXAMPLE 6: CONTACT PATTERN

• Values of contact pattern are depicted in %

• Stored in database with measuring results


STATISTICAL EVALUATION (SPC)


• Measuring of two gears with bore

• Master gear on the left side, measured gear on the right


• Measuring of two very small plastic gear with bore


• Measuring of pinion mounted between centers,

application for motor rotors


• Measuring of rotor, evaluation to bearing surfaces


• Measuring of pump gears mounted between centers


• Measuring of helical gear with spur master gear


• Measuring of rotor shaft for small motors


• Measuring of internal gears for planetary gearboxes


• Measuring of worm gears for very small rotary tables


• Measuring of small gears for dental drill


• Measuring of small bevel gears for dental medicine


• Worm measuring – radial runout and cylindricality


• Measuring of crown gears


• Radial runout – elimination of master gear error


• Mechanical measuring by a dial


• Set of master gears
