Abstract
The invention comprises an idler pulley, having a web and a belt bearing surface connected to the web. The web is aligned with and affixed to an inner race outer surface of a bearing by a fastener. The pulley is stamped, formed or spun out of sheet metal and may have a central hole described by a lip for alignment with a central axis of the bearing. The outer race of the bearing may be affixed to a mounting surface.
Claims25
An idler pulley comprising:
- a belt bearing surface;
- a web connected to the belt bearing surface, the web having a plane normal to the belt bearing surface and having a land portion having a width and being substantially centered in the web;
- the land portion describing a hole for engaging a fastener;
- a bearing having an inner race and an outer race, the inner race having an outer surface normal to a central axis and having an inner race bore;
- and
- the land portion affixed to the outer surface, whereby the belt bearing surface is substantially perpendicular to the outer surface.
