Abstract

1465166 Chain wheels WESTINGHOUSE ELECTRIC CORP 23 May 1974 [25 May 1973] 23078/74 Heading F2Q [Also in Division B8] In an elevator system having an elevator car and a counterweight interconnected by hoisting roping, a weight compensating link chain 72, 74 interconnects the undersides of the car and counterweight and is guided and tensioned by a sheave around which the chain passes the sheave being constructed to minimize chain noise and sway during motion. The sheave comprises axially spaced elastomeric members 54<SP>1</SP>, 56<SP>1</SP> disposed between plate members 58, 60 secured to the sheave core member 40, each member 54<SP>1</SP>, 56<SP>1</SP> being formed as a continuous loop having an inside diameter equal to the outside diameter of the cylindrical member 40. The outside diameter of the members 54<SP>1</SP>, 56<SP>1</SP> is selected to provide a gap between these members to receive alternate chain link 72 normal to the sheave axis, the other alternate chain links 74 pressing radially inwardly of the sheave tending to flatten the elastomeric members 54<SP>1</SP>, 56<SP>1</SP> causing the links 72 to be gripped therebetween. The elastomeric members 54<SP>1</SP>, 56<SP>1</SP> shown are hollow, but may alternatively be solid and in the embodiments of Figs. 7-8 (not shown) these hollow or solid elastomeric members are formed integrally with a common base extending around the core of the sheave.
