Steering pinion geometry control device

Car steering pinion geometry checking device measures :

• Teeth space deviations

• Involute gearing profile checking in defined geometrical cut

• Gear helix angle checking through longitudinal tooth measuring

• Pinion body diameter measuring in several places, i.e. on non-geared pinion cylindrical part

The measuring conception and method:

Control measuring is carried out on horizontal semi-automatic measuring stand being controlled by AMS AC4 electronics equipped with a colour monitor.
Piece insertion is manually-operated, measuring probe movement and positioning is semi-automatic. Report printing, result measuring and archiving device is connected to AMS AC4 electronics.

According to achieved measuring results, checked pinions are automatically indicated as flawless, reparable and flawed.
