Embodiment Construction

[0011] figure 1 Selected portions of the elevator system 20 are shown schematically. The elevator machine assembly 22 includes a motor 24 and a traction sheave 26 . Elevator car 30 and counterweight 32 are suspended by a plurality of load carrying members 28 , such as a rope arrangement including ropes or webbing. For example, load bearing member 28 moves in response to movement of traction sheave 26 to produce the desired motion of elevator car 30 to provide the requested elevator service.

[0012] figure 2 with 3 Selected portions of an exemplary machine assembly 22 are illustrated. In this example, traction sheave 26 is supported by end bells 40 positioned on opposite ends of traction sheave 26 . The end bell 40 and traction sheave 26 are rotatable relative to a stationary shaft 42 . The carriage assembly 44 facilitates the relative rotation required for the desired movement of the traction sheave 26 . In this example, the stationary shaft 42 remains stationary rela...

Abstract

An exemplary bearing cartridge assembly includes an inner sleeve. An outer housing is supported for rotation relative to the inner sleeve. A bearing member within the outer housing and received about the inner sleeve facilitates rotation of the outer housing relative to the inner sleeve. The bearing member has an axial dimension (e.g., a width) that is smaller than an axial inner dimension of the outer housing. The bearing member is positioned relative to the inner sleeve and the outer housing to provide a first lubricant space between one side wall of the outer housing and the bearing member and a second lubricant space between an opposite side wall of the outer housing and the bearing member. There is at least one through passage between the first and second lubricant spaces to allow lubricant to move between them.

Description

Background technique [0001] Elevators carry passengers, goods, or both between different floors in a building. Various devices exist for controlling the movement and position of elevator cars. Some elevator systems are based on traction. Such devices typically include machines that selectively rotate the traction sheave. A load carrying device comprising a rope or belt moves in response to movement of the traction sheave. The load carrying device suspends the car and counterweight within the hoistway. Machine controls are used to control the position and movement of the elevator car. [0002] There are challenges in maintaining such elevator systems. For example, components for elevator machines and traction sheaves need to be strong enough to support the loads associated with the elevator system. In addition, such components must provide sufficient service life so that repair or replacement is not required for a relatively long period of time. Contents of the inventio...
