A Study on the Grinding of the Hourglass Worm Wheel.

Abstract

The high performance of the hourglass worm gearing is well known among all types of worm gearings, especially after the developement of HEDCON【○!R】 worm gear reducer. Despite its high performance, the difficulty in manufacturing the hob is one of the obstacles of production and it has been one of the themes of study. Worm wheel grinding means not only teeth surface grinding but also teeth generating using the electro deposited diamond wheel which shapes the worm thread. This type of grinding wheel has the possibility of being an easy method for producing the worm wheel.
