Abstract
The utility model relates to an anti-thrust assembly of a rotary compressor, which comprises an upper cylinder cover, a motor rotor and a thrust rolling ball bearing, wherein the end part of a shaft neck of the upper cylinder cover is provided with a groove, and the thrust rolling ball bearing is arranged in the groove. Compared with the prior art, the utility model has he advantages of low cost, low electromagnetic sound, little friction and the like.
Description
Technical field
The utility model relates to a kind of compressor, especially relates to a kind of thrust assembly of rotary compressor.
Background technique
Along with the lifting of national air-conditioning efficiency grade, the air condition compressor efficiency requires also more and more higher.One of effective way that improves the compressor efficiency is the folded height that increases motor, but the folded high increase of motor can cause that the another one problem is that compressor shaft is that amount of deflection is excessive, occurs unusual sound in startup and operation process.
At present the thrust mode of compressor shaft system has two kinds, but all is sliding friction pair, and sliding friction pair is in compressor high speed rotating process, and frictional loss is big, and crankshaft thrust face and following cylinder cap easily produce abnormal wear, and is unfavorable to compressor reliability.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of in order to overcome the defective that above-mentioned prior art exists and reduce frictional loss, can improve the compressor efficiency, reduces the thrust assembly of the rotary compressor of electromagnetism sound.
Purpose of the present invention can be achieved through the following technical solutions: a kind of thrust assembly of rotary compressor, comprise upper cylinder cover, rotor, thrust ball bearing, it is characterized in that the axle journal end of described upper cylinder cover offers groove, is provided with thrust ball bearing in this groove.
The lower end surface of described thrust ball bearing contacts with the axle journal end recesses bottom of upper cylinder cover.
The upper-end surface of described thrust ball bearing contacts with the iron core lower end surface of rotor.
Compared with prior art, the utlity model has following advantage:
(1) cost is low: the fine finishing of cancellation crankshaft thrust face, save processing cost;
(2) the electromagnetism sound is little: the thrust function of thrust-bearing, effectively reduce the generation of electromagnetism sound;
(3) friction is little: the change sliding friction is rolling friction, reduces frictional loss, improves the compressor efficiency.
Description of drawings
Fig. 1 is the structural representation of the rotary compressor of band thrust assembly of the present invention;
Fig. 2 is the enlarged view of thrust components of the present invention.
Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
As shown in Figure 1, a kind of thrust assembly of rotary compressor comprises upper cylinder cover 1, rotor 2, thrust ball bearing 3, and the axle journal end of described upper cylinder cover 1 offers groove, is provided with thrust ball bearing 3 in this groove.The lower end surface of thrust ball bearing 3 contacts with the axle journal end recesses bottom of upper cylinder cover 1, and the upper-end surface of thrust ball bearing 3 contacts with the iron core lower end surface 4 of rotor.
The thrust assembly of the utility model rotary compressor is when work, and rotor 2, thrust ball bearing 3 and upper cylinder cover 1 common formation are to the thrust function of compressor shaft system.
