Abstract
The invention relates to an integrated bearing for a scroll compressor applied to a radial flexible mechanism of the scroll compressor, sleeves an eccentric pin crank shaft (1) and clamped into an orbiting scroll (6). The integrated bearing comprises an inner ring bearing (7), a roller (8) and a bearing outer ring (9), wherein the inner ring bearing (7) sleeves the eccentric pin crank shaft (1); the bearing outer ring directly sleeves the outer side of the inner ring bearing (7); the roller (8) is arranged between the inner ring bearing (7) and the bearing outer ring (9). Compared with the prior art, the problem of assembly clearance control of the eccentric shaft sleeve and an orbiting scroll transmission bearing is solved, and the integrated bearing has the characteristics of being good in transmission stability, small in volume and simple in structure, and is applied to a radial flexible drive mechanism of the scroll compressor.
Description
Technical field
The present invention relates to a kind of bearing being applicable in scroll compressor, especially relate to the integrated bearing of a kind of scroll compressor.
Background technique
Common scroll compressor radial compliance mechanism is made up of cam pin bent axle 1, main bearing supporting 2, excentric sleeve 3, balancer weight 4, movable orbiting scroll drive bearing 5, movable orbiting scroll 6, and its structure as shown in Figure 1.
Can there is following problem in existing scroll compressor radial compliance mechanism: movable orbiting scroll drive bearing 5 is difficult to control with excentric sleeve 3 matching gaps; there is axial float and radial deflection in excentric sleeve 3, the unsettled problem of bearing surface carbonic acid of oil and transmission can occur conventionally.
Summary of the invention
Object of the present invention is exactly to provide a kind of movable orbiting scroll drive bearing and the integrated scroll compressor of excentric sleeve integrated bearing in order to overcome the defect that above-mentioned prior art exists, prevent excentric sleeve axial float and radial deflection, improve movable orbiting scroll bearing-transmission stability.
Object of the present invention can be achieved through the following technical solutions:
The integrated bearing of scroll compressor, for scroll compressor radial compliance mechanism, be set on cam pin bent axle and be fastened in movable orbiting scroll, described integral shaft is contracted and is drawn together inner ring axle sleeve, roller and bearing outer ring, described inner ring axle sleeve is set on cam pin bent axle, described bearing outer ring is directly set in the outside of inner ring axle sleeve, between described inner ring axle sleeve and bearing outer ring, is provided with roller.
The sliding groove structure of excentric sleeve is set in described inner ring axle sleeve.
Described inner ring axle sleeve is connected with balancer weight.
Described roller is selected one or more in steel ball roller or cylindrical roller.
Compared with prior art, the invention provides the integrated bearing of a kind of scroll compressor radial compliance sleeve part, solve excentric sleeve and movable orbiting scroll drive bearing fit up gap control problem, there is good transmission stability, the feature that volume is little, simple in structure, is applied to scroll compressor radial compliance driving mechanism.
