Abstract
A semi-rigid elastomeric cover for a roller chain coupling which comprises a generally cylindrical center portion having its radial interior contoured to relatively tightly fit the contour of the roller chain and two opposed axially extending flanges connected to the center portion each flange terminating in a circular beaded portion dimensioned for a compression fit with the hub of the coupling.
Claims9
A semi-rigid elastomeric cover for a roller chain coupling of the type including two sprockets connected to two associated hubs for mounting on substantially aligned shafts, said sprockets having a diameter substantially greater than said hubs and being connected by a double strand of roller chain for transmitting torque from one shaft to the other;
- said cover comprising:
- a one-piece elastomeric member having a generally cylindrical center portion, a contour on the radial interior surface of said center portion configured to tightly fit the double strand of roller chain of said coupling, and two opposed axially extending, outwardly directed flanges connected to said center portion, said center portion having an interior diameter that is substantially greater than the interior diameter of said flanges.
A semi-rigid elastomeric cover for a roller chain coupling of the type including two sprockets connected to two associated hubs for mounting on substantially aligned shafts;
- said sprockets being of a substantially greater diameter than said hubs and being connected by a double strand of roller chain for transmitting torque from one shaft to the other;
- said cover comprising;
- a one-piece elastomeric member having a generally cylindrical center portion, at least part of which has an inside diameter greater than said sprocket diameter, a pair of radially inwardly directed projections extending from said center portion, each of which is positioned to fit against a circular row of rollers of said roller chain, two opposed axially outwardly directed flanges connected to the radially innermost edges of said center portion and having portions whose interior diameter is smaller than said hub diameter, and two circular beads, each of which is connected to the axially outermost edge of one of said flanges, respectively.
