关于Φ3.5m立式减速机高速齿轮的改造

Improving on the high speed gear of 3 5m vertical type decelerator

介绍了在不改变中心距和传动比的前提下提高齿轮模数，增强齿轮的抗弯能力。

A method of raising the bending resistance ability and working life of the gear is provided ,on the occasion of not changing the centre distance and rotation ratio,but the gear modulus improved.
