Problems solved by technology

[0005] However, due to factors such as the structure and installation of the cage, although the thrust gasket is provided with an oil injection port, the lubrication of the rolling elements in the thrust bearing is not enough to meet the increasing lubrication requirements, and the thrust bearing is prone to early failure

Embodiment Construction

[0036] figure 1 shows a top view of a thrust bearing according to a preferred embodiment, figure 2 shows the basis figure 1 A half-sectional view of the thrust bearing at section A-A of , and image 3 shows the basis figure 1 A half-sectional view of the thrust bearing at section B-B.

[0037] The thrust bearing according to the present embodiment can be axially supported between the shaft and the bearing housing. Such as figure 2 with image 3 As shown, the thrust bearing includes a rolling element and cage assembly and two thrust washers 3,4. The rolling element and cage assembly includes a cage 1 and a plurality of rolling elements 2 .

[0038] Cage 1 is configured as a ring overall. The cage 1 here consists of a thin-walled annular plate part with a W-shaped cross section. The bulge in the radial middle area of ​​the cage 1 forms pockets distributed in the circumferential direction, wherein the pockets penetrate the axial ends of the cage 1 in the axial directio...

Abstract

The invention relates to a holder, a rolling body and holder assembly and a thrust bearing. The holder (1) is integrally constructed to be annular and is provided with pockets distributed in the circumferential direction, wherein the pockets penetrate through the two axial ends of the holder (1) in the axial direction, grooves (5a and 5b) for flowing of a lubricant are formed in the outer circumference and / or the inner circumference of the holder (1), and the grooves (5a and 5b) penetrate through the two axial ends of the holder (1) in the axial direction. The rolling body and holder assembly comprises the holder (1) and a plurality of rolling bodies (2), wherein the rolling bodies (2) are arranged in the pockets of the holder (1). The thrust bearing comprises the rolling body and holder assembly or at least one thrust gasket (3 and 4), and the thrust gaskets (3 and 4) are arranged on the axial end sides of the rolling body and holder assembly.

Description

technical field [0001] The invention relates to the technical field of bearings. The invention particularly relates to a cage, a rolling element and cage assembly, and a thrust bearing. Background technique [0002] In today's transmission applications, especially automatic transmissions (AT) or hybrid-specific transmissions (DHT), due to the increasing speed and load, the lubrication requirements for the bearings in the transmission are also increasing. [0003] Chinese patent document CN 101622465 A discloses a thrust bearing that can be used in a gearbox. In this solution, the thrust bearing includes rolling elements in the form of needle rollers, a cage and thrust washers. In this case, the cage is formed from a bent, thin-walled annular plate part. [0004] At present, in order to realize the lubrication of the above-mentioned type of thrust bearing, an oil injection port is generally provided at the thrust pad. The injected lubricating oil passes through the gap be...
