Abstract
An elevator sheave () includes a belt guiding surface () having a surface profile along at least a portion of the belt guiding surface. The surface profile preferably is defined by an norder polynomial equation where n is a number greater than 2. In one example, the reference point () is a central point along the width of the belt guiding surface (). In one example, a central portion () of the surface profile preferably is aligned to be generally parallel with the central axis () of the sheave body. Some examples have curvilinear side portions () between the central portion () and the edges () of the sheave. Other examples also include second side portions () that have linear profiles.
