Abstract
The utility model relates to a compressor with a plane thrust ball bearing, which comprises a crankshaft (5) and a crankshaft case (6), and is characterized in that the plane thrust ball bearing is arranged between a thrust surface of the crankshaft and a thrust surface of the crankshaft case, a nonmetal washer (4) with certain elasticity is additionally arranged on the lower portion of the plane thrust ball bearing, and the thickness of the nonmetal washer ranges from 0.5mm to 5mm. The efficiency of a reciprocating refrigerator compressor can be improved by 2-3%, and simultaneously stable running of the compressor can be guaranteed.
Description
Technical field
The utility model relates to a kind of freezer compressor, particularly to the plane thrust ball bearing structure between the thrust face of thrust surface that is arranged on bent axle and crankcase.
Background technique
Conventional reciprocating formula freezer compressor, the thrust surface of bent axle and the thrust face of crankcase form a plane sliding bearing, and the friction wasted work is bigger.At present, existing fully closed compressor adopts the plane thrust rolling bearing of being made up of upper support sheet, ball, retainer, lower support sheet, although can make compressor become linear rolling by planar slide, thereby improve friction, raise the efficiency, but because there is form and position tolerance in the component such as crankcase of compressor in course of working, in the compressor operation process owing to axially be subjected to impacting etc. and cause motion to depart from desirable working position, be difficult to mechanism is adjusted, cause mechanical friction to increase, compressor efficiency reduces.
Summary of the invention
The technical problems to be solved in the utility model is how further to reduce the wasted work that rubs between crankshaft thrust face and the crankcase thrust face, and a kind of efficient freezer compressor is provided.
The purpose of this utility model is achieved in that a kind of compressor with the plane thrust ball bearing, comprise bent axle and crankcase, it is characterized in that: be provided with the plane thrust ball bearing between the thrust surface of bent axle and the thrust face of crankcase, set up one in the bottom of described plane thrust ball bearing and have the certain flexible certain thickness packing ring that has.The utility model adopts a plane thrust ball bearing to replace plane sliding bearing, has greatly improved Frotteurism, has reduced the friction wasted work at this position.Simultaneously, on the basis of adopting the plane thrust ball bearing, increase a packing ring in the bottom of this bearing in addition,, further reduce the wasted work that rubs with the further friction that improves this ball bearing.
The mounting type of described plane thrust ball bearing and packing ring can be by a circular groove or a deep gouge are set on crankcase, and described plane thrust ball bearing and packing ring are placed in described circular groove or the deep gouge.
For the elastic force of improving described packing ring to adapt to the institutional adjustment requirement, described packing ring is preferably selected the nonmetallic material packing ring.
Further preferred version is that the thickness of described packing ring is between 0.5mm-5mm, this packing ring can be along the hole that different shapes such as circle more than 2, square, ellipse evenly are set on the packing ring circumferencial direction, also can be real core, can also be to be evenly distributed with hemispheric projection in washer face.
The utility model can the generating technique effect foundation be based on following principle:
1. because the morpheme error that part processing produces, machinery after causing assembling fails to reach desirable state, as the cylinder-bore of crankcase and the perpendicularity in crankshaft hole two holes, the parallelism of connecting rod, the perpendicularity equal error of the piston pin hole on the piston, finally cause connecting rod not turn round ideally, thereby increase extra friction wasted work.After increasing this nonmetal elastic washer, elasticity that can be by elastic washer self is carried out to a certain degree adjustment to mechanism, reaches the purpose of the wasted work that reduces to rub.
2. mechanism is that bringing onto load moves, and especially compressor is in compression, exhaust process, and mechanism is subjected to bigger gas force, can cause mechanism to depart from desirable running state, and mechanism will consume extra wasted work.After increasing this nonmetal elastic washer, can so that mechanism be subjected to external force do the time spent automatically adaptation mechanism depart from ideal position, thereby can make that still mechanism moves under comparatively ideal state, to reduce the wasted work that rubs.
The utility model can make compressor efficiency improve 2-3% owing to adopt the plane thrust ball bearing structure, can ensure the stable operation of compressor simultaneously.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
In bent axle 5 thrust surfaces and crankcase 6 circular grooves or counterbore, place packing ring 4 from lower to upper successively, lower support sheet 3, ball bearing 2, upper support sheet 1, the thickness of packing ring is between 0.5mm-5mm, this packing ring can be along the hole 7(that different shapes such as circle more than 2, square, ellipse evenly are set on the packing ring circumferencial direction shown in Fig. 3,4,5), also can be real core, can also be to be evenly distributed with hemispheric protruding 8(as shown in Figure 6 in washer face).The utility model can overcome the defective of bent axle 5 thrust surfaces and crankcase 6 shaft shoulder planar parallelism differences in the prior art in operation process, solve the positional error problem that the axial impact distortion produces simultaneously, can improve compressor efficiency 2-3%.
