Bevel gear e.g. differential gear, manufacturing method, involves cold working end contour of toothing, mechanically finishing bevel gear and implementing hardening of bevel gear in form of tumbel press
摘要
<p>The method involves axially forging a bevel gear body (1`) with a toothing (2) preform, and annealing the gear body. The gear body is surface cleaned and the end contour of the toothing is cold worked. The bevel gear is mechanically finished and the hardening of the bevel gear is implemented in the form of a tumbel press. The toothing of the gear body is inserted into a die provided with a negative mould of the toothing.</p>
