Abstract

An illustrative example embodiment of an elevator compensation assembly includes at least one compensation sheave having an outer surface configured to engage a plurality of compensation rope members. A guard has an inner surface situated adjacent the outer surface of the compensation sheave. A plurality of dividers that extend away from at least one of the outer surface of the compensation sheave or the inner surface of the guard. The dividers establish a space between adjacent ones of the dividers for accommodating a compensation rope member.

First claim

I claim:

1 . An elevator compensation assembly, comprising:
at least one compensation sheave having an outer surface configured to engage a plurality of compensation rope members; a guard having an inner surface situated adjacent the outer surface of the compensation sheave; and a plurality of dividers that extend away from at least one of the outer surface of the compensation sheave or the inner surface of the guard, the dividers establishing a space between adjacent ones of the dividers for accommodating a compensation rope member.

2 . The elevator compensation assembly of claim 1 , wherein the dividers each comprise a flange on the outer surface of the at least one compensation sheave.

3 . The elevator compensation assembly of claim 2 , wherein the dividers each comprise a rib on the inner surface of the guard.

4 . The elevator compensation assembly of claim 2 , wherein the dividers each comprise a groove on the inner surface of the guard.

5 . The elevator compensation assembly of claim 2 , comprising a plurality of compensation rope members received on the outer surface of the compensation sheave and wherein
the flanges extend from the outer surface of the compensation sheave a distance corresponding to at least one-half a thickness of the compensation rope members.

6 . The elevator compensation assembly of claim 1 , wherein the dividers each comprise a rib on the inner surface of the guard.

7 . The elevator compensation assembly of claim 1 , wherein the dividers each comprise a groove on the inner surface of the guard.

8 . An elevator system, comprising the compensation assembly of claim 1 , an elevator car, a counterweight, and a plurality of compensation rope members coupled to the elevator car and the counterweight, the plurality of compensation rope members being respectively received in the spaces between the adjacent ones of the dividers.

9 . The elevator system of claim 8 , wherein the compensation sheave includes a plurality of grooves on an exterior of the compensation sheave and the compensation rope members are respectively received in the grooves.

10 . A method of controlling a position of elevator compensation rope members, the method comprising placing a compensation rope member within each of the spaces of the elevator compensation assembly of claim 1 .
