Abstract
An automobile air-conditioning compressor swaying tray bushing mainly comprises a swaying tray 3 and a bushing 2. Besides, a spiral oil return groove 1 is arranged on the inner surface of the bushing 2. The automobile air-conditioning compressor swaying tray bushing is extremely simple in implementation by only omitting three originally designed oil return grooves and processing the spiral oil return groove on the inner surface of the bushing. As the spiral oil return groove 1 can continuously provide lubricating oil for the bushing and a tilting tray, resistance of the bushing in matched rotation with the tilting tray and abrasion of the bushing are decreased, and the service life of a compressor is effectively prolonged.
Description
Technical field
The utility model is mainly used in automobile air conditioner compressor, a kind of automobile air conditioner compressor shaking tray lining.
Technical background
In automobile air conditioner compressor was produced, shaking tray was one of indispensable critical piece that drives piston motion, was set in lining internal diameter in the shaking tray and cooperated with the swash plate external diameter and rotate, and therefore, needed at work to lubricate.Traditional lubricating system is to be laid with three oil-return grooves with the lining parallel axes on the lining inner ring surface.Yet when running up, the fuel system of this interruption of oil-return groove tends to swash plate is produced certain resistance, thereby has aggravated the wearing and tearing of lining internal diameter and reduced working life of compressor.
The purpose of this utility model is in order to guarantee the normal operation of lining and swash plate, the oil-return groove on the lining have been carried out improving to satisfy the needs of compressor proper functioning.
Summary of the invention
Automobile air conditioner compressor shaking tray lining mainly is made up of shaking tray 3 and lining 2, is provided with a spiral helicine oil-return groove 1 on the internal surface of lining 2.
The beneficial effects of the utility model are: spiral helicine oil-return groove 1 can be continuous for providing lubricant oil between lining and the swash plate, and the resistance when having reduced to cooperate rotation with swash plate and the wear extent of lining effectively raise working life of compressor.
Description of drawings

Fig. 2 is an A-A cross section view of the present utility model;
Fig. 3 is the plan view before the utility model improves;
Fig. 4 is the A-A cross section view before the utility model improves.
In the accompanying drawing: 1, oil-return groove; 2, lining; 3, shaking tray.
Embodiment
Automobile air conditioner compressor shaking tray lining is implemented very simply, only needs intrinsic three oil-return grooves of cancellation, both can at spiral helicine oil-return groove of internal surface processing of lining.Since spiral helicine oil-return groove 1 can be continuous for providing lubricant oil between lining and the swash plate, thereby reduced to cooperate the resistance when rotating and the wear extent of lining with swash plate, effectively raise the working life of compressor.
