Single Flank TAC test
The Single Flank TAC test allows a practice-oriented simulation of the operating situation of a pinion outside the gear under real load conditions like center distance, load and rotation speed. This testing method is particularly used for the detection of faults in the gear geometry as like as cyclic running, meshing-deviations or Teilungsfehler. The basic configuration of this testing method is quite identical with that of the single flank test according to DIN 3970. The advantage of this testing method is, that the test results can be determined directly from the measured torsional accelerations, and not indirectly by a comparison of the angles of rotation as it is done by the single flank test of DIN 3970.
The meshing of the specimen with the master gear takes place by a constant invariable) centre distance referring to the dimension „a“ of the gear wheel assembly. The meshing performed only in one direction of rotation (clockwise or anticlockwise), in the same direction of rotation as the work piece is used in practice.
Both gears, the specimen and the master gear, have a separate servo-drive, by which they can introduce the movement of rotation or cause a braking torque. The meshing operation is carried out in 2 cycles:
In the first cycle the specimen drives the master gear, during the drive of the master causes the braking torque. In the second cycle the drives are changed, i.e. the master gear is driving and the specimen is braking. This change is necessary for testing both flanks of the gear.
The range of revolution of the driving gear amounts 100-1200 rpm, at a range of torque of M = 0.5 - 4.5 [Nm].

Sensorics
The recording of the values like uneven rotations, damages – and faults of gearings are recorded by a rotary acceleration sensor, that is mounted at the master-gear shaft.
