Bearing cartridge and elevator machine assembly

摘要

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.

主权项

1. A bearing cartridge assembly, comprising:
an inner sleeve; an outer housing supported for rotation relative to the inner sleeve, the outer housing having side walls at opposite axial ends of the outer housing, the outer housing having an end wall extending in an axial direction between the side walls, wherein the end wall and the side walls are situated with respect to the inner sleeve so that there is a closed interior space defined between the sidewalls of the outer housing and between the end wall of the outer housing and an axially extending, radially outer most surface on the inner sleeve, the side walls of the outer housing having radially facing ends that are received adjacent to the axially extending, radially outermost surface of the inner sleeve; and a bearing member within the outer housing and received about the inner sleeve for facilitating rotation of the outer housing relative to the inner sleeve, the bearing member having an axial dimension that is smaller than an axial dimension of the end wall in the interior space, the bearing member being positioned relative to the inner sleeve and the outer housing to provide a first lubricant space between one of the side walls of the outer housing and the bearing member.
