Even when driving down a perfectly straight road, it is necessary to turn the steering wheel vigorously from leftto right every few moments.

就算开直路，也必须三不五时地大力向右打方向盘。

Base on JM 14 type low speed winch, this paper changes from worm-worm wheel transmisson to straight spur gear transmisson. It becomes a new type JHS 140 type prop-pulling winch.

在现有的JM14型慢速绞车的基础上，将蜗杆蜗轮传动改为直齿圆柱齿轮传动，成为一种新型的JHS140型回柱绞车。

This paper gives the new technique of tooth profile on the normal section of nobbing-shaving cutter involute worm which is imitated by hyperbola and suggests that axial section of grinding wheel can be obtained in hyperbolic form by dressing conical surface of grinding wheel along the inclined straight line.
