Abstract
A minimum grip drive sprocket. A sprocket having a knurled chain engagement surface rotably engages a drive chain typically in an environment exposed to a slick or lubricating medium allowing an acceptable degree of drive chain slip while maintaining rotation of the minimum grip drive socket.
Claims20
A chain drive comprising:
- a drive chain having a plurality of chain segments, each segment including a pair of link plates separated at a fixed distance by a pair of rollers;
- a minimum grip drive sprocket having a top bevel and a bottom bevel around an outer circumference of the minimum grip drive sprocket, the minimum grip drive sprocket engaging the drive chain rollers;
- whereby the drive chain rollers may intermittently slip over a knurled surface on an edge of the minimum grip drive sprocket;
- and
- whereby the top bevel and the bottom bevel are sized so that the pair of link plates do not prevent the rollers from contacting the edge.

A minimum grip drive sprocket comprising:
- a circular piece having an outer circumference, a top side, and, a bottom side, the circular piece including:
- a top circular bevel extending from an outer top edge of the circular piece and thickening towards a center of the circular piece,
- a bottom circular bevel extending from an outer bottom edge of the circular piece and thickening towards the center of the circular piece;
- and
- a roughened surface treatment applied to the outer edge.
2 more elements
A minimum grip drive sprocket comprising:
- A circular shaped sprocket body having a top side, and a bottom side, in which a thickness of the sprocket around an edge of the circular shaped sprocket body is sized so that a roller disposed between a pair of parallel links of a coupled drive chain do not contact the top side and the bottom side of the sprocket body;
- and
- a roughened surface disposed on an outer edge of the circular shaped sprocket body that engages the rollers of the drive chain.
