Abstract
The utility model provides a synchronous and speed changing driving wheel. The outer wall of the synchronous and speed changing driving wheel is in a stepped shape, and the synchronous and speed changing driving wheel is provided with a large-diameter end and a small-diameter end. The outer side of the large-diameter end and the outer side of the small-diameter end are both provided with evenly-distributed tapered teeth. A protruding partition ridge is formed between the large-diameter end and the small-diameter end. The diameter of the tooth tops of the tapered teeth at the large-diameter end is larger than that of the tooth tops of the tapered teeth at the small-diameter end. The synchronous and speed changing driving wheel is capable of being connected with two conveying belts to change the transmission speed.
Description
