Adjustable sprocket with different shaft diameter?
A sprocket is a wheel with a cog-type sprocket, which is used to mesh with an accurate pitch block on a chain link or cable: a solid or spoked Gear that meshes with a (roller) chain for transmission Movement, sprocket is widely used in chemical transmission, textile machinery, food processing, instrumentation, petroleum machinery and other industries. The sprocket shaft holes in the market are generally fixed in size and are not adjustable. A sprocket is fitted to a shaft, and the shaft is installed in the shaft hole. Therefore, in some cases, the shaft hole of the sprocket is not suitable. Scrap the sprocket, so design a sprocket that can adapt to different shafts.
The sprocket body with adjustable shaft diameter is provided with a shaft hole, and a shaft sleeve for fixing the rotating shaft is provided in the shaft hole. The shaft sleeve is composed of at least four retractable clamping blocks, which are evenly distributed in the circumferential direction and fixed on the clamping blocks. The screw is connected. The sprocket body is provided with a mounting slot for the screw to pass through. The sprocket body is provided with a groove. The screw is provided with an adjusting shaft sleeve that cooperates with the screw thread. The groove is used to place the adjusting shaft sleeve. There is a scale on the end face of the adjusting shaft sleeve; the limiting block is fixedly connected to the screw; the side wall of the mounting groove is provided with a limiting groove for supplying the sliding of the limiting block; the inner side wall of the clamping block is provided with a wear-resistant protrusion ;
Compared with the prior art, the beneficial effect is that the screw extends into the installation groove, and an adjusting shaft sleeve fitted with the screw thread is provided on the screw. The adjusting shaft sleeve restricts the installation position in the groove, and the adjusting shaft sleeve is adjusted by rotating. It can make the length adjustment of the telescopic block more precise. Since the telescopic length of the telescopic block can be precisely adjusted when the sleeve is rotated 360 degrees, the center position of the shaft hole of the sprocket can be adjusted at will while improving the adjustment progress. , Increase the application range of the sprocket, reduce the replacement of the sprocket, and can adapt to a variety of shafts.
