Abstract
A combination coupling and sheave in a variable speed belt drive in which a variable pitch sheave has a fixed flange, an axially shiftable flange and a shaft connected to the drive motor by a flexible coupling with the hubs thereof secured to the motor and sheave shaft. The inventive concept includes mounting the coupling hub on the sheave shaft in a bearing of a pillow block at the end of the shaft and connecting the fixed flange of the sheave to the hub, so that the fixed flange is driven directly by the hub rather than solely by the shaft, and the slidable flange is driven through the shaft, thus creating split power paths between the flexible coupling and the fixed flange and between the coupling and the slidable flange through the sheave shaft, thereby reducing the load on the operating parts of the sheave.
