Roller thrust bearing vibration isolator

摘要

A vibration isolator for use between a support structure and a roller thrust bearing including a first race, a second race, a bearing cage and at least one roller element. The vibration isolator includes a radially extending portion with a mating surface, a bearing surface, an inner peripheral edge and an outer peripheral edge, the radially extending portion being substantially disk-shaped. An annular flange extends axially from one of the inner peripheral edge and the outer peripheral edge of the radially extending portion, and at least one groove is defined by the mating surface of the radially extending portion. The bearing surface is configured to abut one of the first race and the second race and the mating surface is configured to abut the support structure such that a void is defined between the at least one groove and the support structure.

1. A vibration isolator for use between a support structure and a roller thrust bearing including a first race, a second race, a bearing cage and at least one roller element, comprising:
a radially extending portion with a mating surface, a bearing surface, an inner peripheral edge and an outer peripheral edge, the radially extending portion being substantially disk-shaped; an annular flange extending axially from one of the inner peripheral edge and the outer peripheral edge of the radially extending portion; and the mating surface of the radially extending portion defining a plurality of ridges and a plurality of grooves, each groove being disposed between adjacent ridges, and each ridge having a substantially angular cross-section along its length, thereby forming an angular peak along an outermost portion of each ridge, wherein the bearing surface is configured to abut one of the first race and the second race, the angular peaks of the mating surface are configured to abut the support structure such that a plurality of voids is defined between the plurality of grooves and the support structure, and each ridge extends radially outwardly from the inner peripheral edge to the outer peripheral edge of the radially extending portion.
