Background technique
Existing rotary compressor; As shown in Figure 1; Described compressor comprises seal casinghousing, is installed in electric machine assembly and pump assembly in the seal casinghousing; Electric machine assembly is made up of stator and rotor, pump assembly comprise the cylinder that has vane slot, the upper bearing (metal) that is used to seal and lower bearing, hot jacket at epitrochanterian bent axle, be positioned over piston in the cylinder, be positioned over the slide plate in the vane slot, owing to be sliding friction between slide plate head and piston periphery; The big slide plate wearing and tearing of friction factor are bigger, and the compressor power consumption is big like this.These engineers and technicians are improved, carry out wear-resistant processing or self lubricating material employing at slide plate head surface and piston outer surface, to increase the wear resistance of slide plate.Or the slide plate and the way of contact of piston periphery changed into rolling contact; Like the disclosed application number of Chinese patent document is a kind of compressor patent of CN200620044268.6; This compressor comprises slide plate and vane slot; Through at least one needle roller is set in vane slot, perhaps the slide plate head also is provided with a needle roller.It is said that it can reduce the wearing and tearing between slide plate and the vane slot internal surface, and then reduce the loss of compressor power input, improve the reliability of compressor.But wherein do not provide the concrete structure of this kind slide plate head, and adopt which kind of mode to prevent coming off of needle roller when not having slide plate head mounting groove to be processed into circle.Therefore, be necessary to do further improvement and perfect.
The model utility content
The purpose of the utility model aims to provide a kind of simple and reasonable, rotary compressor that fabricating cost is low, applied widely, to overcome deficiency of the prior art.
A kind of rotary compressor by this purpose design; Comprise seal casinghousing, be installed in electric machine assembly and pump assembly in the seal casinghousing; Electric machine assembly is made up of stator and rotor; Pump assembly comprise the cylinder that has vane slot, the upper bearing (metal) that is used to seal and lower bearing, hot jacket at epitrochanterian bent axle, be positioned over piston in the cylinder, be positioned over the slide plate assembly in the vane slot; The slide plate assembly is made up of slide plate and needle roller, and the slide plate head has the mounting groove that needle roller is installed, and its structure characteristic is that the slide plate head is provided with the boss mechanism that is used to prevent the needle roller disengaging.
Said boss mechanism is one group with two and is symmetrical set on the slide plate head and protrudes from mounting groove; Boss mechanism is more than 1 group or 1 group.
Said boss mechanism is formed by side extrded material in mounting groove of slide plate head, and boss mechanism protrudes from the inner side surface of mounting groove.
Said boss mechanism is formed by front end extrded material in mounting groove of slide plate head, and boss mechanism is depressed in the slide plate front end.
The thin space of said slide plate head mounting groove is L1, and the needle roller diameter is d, and L1＜d-0.02mm is then arranged.
The thin space of said slide plate head mounting groove is L2, and the needle roller diameter is d, and L2＜d-0.02mm is then arranged.
Because needle roller is installed in the slide plate head mounting groove, need prevent that when compressor operating needle roller breaks away from the slide plate mounting groove.The utility model is through being provided with the boss mechanism that is used to prevent the needle roller disengaging at the slide plate head, this boss is by the extrded material moulding of slide plate side, and perhaps slide plate front end extrded material moulding prevents that the radially break-off when needle roller reaches operation when mounted from occurring.
