One-piece thrust bearing

Abstract

The invention discloses an integrated thrust bearing, and belongs to the technical field of bearings. The integrated thrust bearing comprises a blowout patch seat and a bezel seat, wherein a blowout patch is arranged on the blowout patch seat, a bezel is arranged on the bezel seat, and a steel ball-holder assembly is arranged between the bezel and the blowout patch; a mandrel is arranged on the inner circles of the bezel and the blowout patch, the blowout patch is fixedly arranged on the mandrel, and space is formed between the inner circle of the bezel and the outer circle of the mandrel; a ring groove is arranged at the end of the mandrel, an axial retainer ring is arranged in the ring groove, and a washer is arranged on the mandrel between the axial retainer ring and the bezel; and the structure of the integrated thrust bearing is formed by the bezel, the steel ball-holder assembly, the blowout patch, the mandrel, the washer and the axial retainer ring. Each part of the integrated thrust bearing disclosed by the invention is integrated into a whole and non-separation no matter in free state or in working state, prevents the bezel and the steel ball-holder assembly from dislodging effectively, enables the whole bearing to be modularized, and is more convenient and more safe to use.

Description

Technical field [0001] The invention relates to a thrust bearing and belongs to the technical field of bearings. Background technique [0002] The existing thrust bearings are divided into thrust ball bearings and thrust roller bearings. Thrust bearings have the characteristics of small volume, small mass, compact structure, high-speed operation and stable operation, bearing large axial force and not bearing radial force, which determines that the thrust bearing is suitable for no radial force but larger axial direction High-speed or low-speed occasions. The thrust bearing is structurally divided into three parts: shaft washer, seat ring and steel ball-cage assembly, and the three parts are separated from each other, which brings greater limitations to the use of thrust bearings. Especially when the thrust bearing is installed vertically and inclinedly, under the combined action of a series of complex conditions such as its own gravity, the gravity of other related parts, the o...

AI Technical Summary

Problems solved by technology

Thrust bearings are structurally divided into three parts: shaft ring, seat ring and steel ball-cage assembly, and the three parts are separated from each other, which brings great limitations to the use of thrust bearings

Especially when the thrust bearing is installed vertically or obliquely, under the comprehensive action of its own gravity, the gravity of other related parts, the operating force, and the operating inertia, etc., the seat ring and the steel ball-cage are very easy to leave the original position. In the slightest, the machine cannot operate normally, and in the worst case, the machine parts are destroyed, resulting in serious accidents.
