Japanese Patent JP2652660
Kind Code:
B2
Abstract:
PURPOSE:To decrease a noise caused by backlash in a connection part of a spline to a gear by connecting the gear to the spline, formed in a load shaft mounting a tool, through an elastic member. CONSTITUTION:An elastic member 8 is interposed in a condition connecting a gear 3 to a load shaft 5. In this way, even when a spline 4, serving as a different connecting mechanism formed between the gear and the shaft, forms a play-provided fitting condition by backlash, this condition can be substantially eliminated. Accordingly, a phenomenon such as reflecting an impact between an electric motor in its shaft 1 and a grinding wheel 6, mounted to the load shaft 5, is eliminated, and a noise is prevented from being generated.
