Embodiment Construction

[0014] The design of the three-ring slewing bearing for automobile test bench of the present invention is to combine two single-row four-point contact ball slewing bearings sharing one middle ring, wherein the outer ring, middle ring, outer ring steel balls and outer sealing ring constitute the first A single-row four-point contact ball slewing bearing, the inner ring, middle ring, inner ring steel balls and inner sealing ring constitute the second single-row four-point contact ball slewing bearing, and the middle ring is shared by two single-row four-point contact ball slewing bearings Ferrule; four-point contact ball means that the steel ball of the outer ring is only in contact with two points of the raceway of the outer ring and two points of the raceway of the middle ring or the steel ball of the inner ring is only in contact with two points of the raceway of the middle ring and the raceway of the inner ring Two touches.

Abstract

The present invention discloses a three-ring turnplate bearing design and structure used in automobile test-bed, which is composed by a outer lane plug 1, a outer lane wedge pin 2, an outer sealing ring 3, a middle lane 4, an inner sealing ring 5, a inner lane wedge pin 6, a inner lane plug 7, an inner lane 8, an inner lane steel ball 9, an outer lane steel ball 10 and an outer lane 11, wherein aball rollaway nest is set on the surface of inner and outer cylinder of the middle lane to mount the inner and outer lane steel ball; meanwhile a sealing groove is set respectively to mount the innerand outer sealing ring; a ball rollaway nest is set on the inner lane and outer lane; a plug hole is set respectively at the same time to mount the plug of the inner and outer lane; a wedge pin hole is set above the plug hole on the end-face of the inner and outer lane to mount the inner and outer lane wedge pin and they pin the inner lane, the inner lane plug, the outer lane and the outer lane plug together; the outer lane, the middle lane, the outer lane steel ball, the outer sealing ring, the outer lane plug and the outer lane wedge pin consists of the first monostichous quatre contact ball turnplate bearing, and the inner lane, the middle lane, the inner lane steel ball, the inner sealing ring, the inner lane plug and the inner lane wedge pin consists of the second monostichous quatrecontact ball turnplate bearing.

Description

technical field [0001] The invention belongs to the technical field of bearing design, in particular to the design and structure of a three-ring turntable bearing used in an automobile test bench. Background technique [0002] The motion relationship in the automobile test bench is complex, and the existing various forms and types of bearings cannot meet its requirements. Special bearings for automobile test benches are technically blank. In order to meet the rapid development of the automobile industry for the automobile test bench, it is necessary to develop a slewing bearing that can meet the complex motion relationship in the automobile test bench. Contents of the invention [0003] Aiming at the special requirements of the automobile test bench for the bearing, the present invention designs a three-ring slewing bearing for the automobile test bench. The bearing is aimed at the special working conditions of the automobile test bench, and adopts a reasonable bearing st...
