Transmission gear (gear pitch)

Application:

A family of transmission gears with gear teeth not evenly divisible by three, are chucked on their pitch diameter and located on the rear face for ID
grinding.

Changeover from one gear to another must be
accomplished in less than 5 minutes without
extensive adjustments by the operator.

Required accuracy: 0,012 mm TIR

Solution:

MicroCentric produced an air chuck with "pull-down" clamping action, complete with special top jaws and part locators. The chuck used our QC jaw system, and was supplied with hardened top jaws which use interchangeable gear pins to contact the gear's tooth form. The system produced concentric location of the gear relative to its' pitch diameter.

Achieved accuracy: 0,005 mm (incl. changeover)

Technology: APC
