Gear wheel forming process

摘要

The gear wheel blank (2) is clamped by axial grips (4) to rotate about the centre axis (3) of the blank. The rim (25) of the blank is inductively heated and the gear profile is rolled into the plastic rim by a shaped tool (17) which rotates about the circumference of the blank. The formed gear wheel is then inductively hardened. The blank is further supported between telescopic grips (8,9) with recesses (18) near the blanks which accommodate the clamping supports of the press tool. The gear teeth can be formed in two stages for an improved profile.
