The oil-free automobile air compressor disclosed by the utility model is mainly used in an automobile engine to compress air.
Description
Technical field
The utility model relates to a kind of no petrol car air compressor, and it belongs to technical field of automobile engine.
Background technique
Air compressor is the main body in the compressed air source unit, it be mechanical energy with prime mover (normally motor) convert to gas pressure can device, be compressed-air actuated air pressure generating means, Piston Air Compressor is a kind of in the air compressor.Need organic oil in the existing air compressor cylinder body, and in the course of the work, machine oil is easy to scurry in the outlet pipe, thereby influences the performance of braking system; The existing piston material is generally aluminum alloy, and cylinder body then is a cast iron, and both expansion coefficient are different, require cylinder prepareding gap bigger, thereby causes piston in cylinder body, to shake momentum, shock momentum and to scurry oil mass all bigger.
The model utility content
There is the deficiency of scurrying oil, pistons work less stable in the utility model to air compressor, and a kind of no petrol car air compressor is provided.
The technological scheme that the utility model solves the problems of the technologies described above is following:
A kind of no petrol car air compressor comprises cylinder body, through wrist pin piston is installed in the said cylinder body, and said cylinder body top is provided with cylinder cap, and the below is provided with crankcase; The bottom of said cylinder cap is equipped with valve plate through bolt, is provided with bent axle in the said crankcase; Said wrist pin links to each other through connecting rod with bent axle; Between said bent axle and the crankcase, all link to each other between connecting rod and the crankshaft and piston pin through the selflubricating rolling bearing; The surface of said piston evenly is coated with Teflon.
Compared with prior art, the beneficial effect of the utility model is: the application of selflubricating rolling bearing can guarantee under the state that does not have oil, also can reach good working performance; Unlubricated oil in the cylinder body does not have and scurries oily phenomenon, thereby has improved the stability of braking, inorganic oil loss greatly; The spraying Teflon can effectively reduce the friction factor between piston and the cylinder body.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, be provided with the Teflon piston ring between said piston and the cylinder body.
Adopt the beneficial effect of above-mentioned further scheme to be: piston ring can increase the sealability between piston and the cylinder body; The Teflon piston ring can effectively reduce the frictional force between piston and the cylinder body, effectively increases the service life.
Further, said cylinder body is an aluminum alloy material; Said inner surface of cylinder block is through nickel plating or anodizing.
Adopt the beneficial effect of above-mentioned further scheme to be: the change and the piston of cylinder block material are all aluminum alloy, and its expansion coefficient is the same, can reduce cylinder prepareding gap, and plating nickel on surface or anodizing make hardness can reach more than the HV300, improve wear resistance.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Cylinder cap in the drawings, 1; 2, valve plate; 3, cylinder body; 4, piston ring; 5, piston; 6, crankcase; 7, bent axle; 8, selflubricating rolling bearing; 9, wrist pin; 10, connecting rod.
Embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
A kind of no petrol car air compressor comprises the aluminium alloy cylinder 3 of internal surface through nickel plating or anodizing, through wrist pin 9 piston 5 that the surface is coated with Teflon is installed in the said cylinder body 3, and said cylinder body 3 tops are provided with cylinder cap 1, and the below is provided with crankcase 6; Be provided with Teflon piston ring 4 between said piston 5 and the cylinder body 3; The bottom of said cylinder cap 1 is equipped with valve plate 2 through bolt, is provided with bent axle 7 in the said crankcase 6; Said wrist pin 9 links to each other through connecting rod 10 with bent axle 7; Between said bent axle 7 and the crankcase 6, all link to each other between connecting rod 10 and bent axle 7 and the wrist pin 9 through selflubricating rolling bearing 8.
The utility model is when making, and the Teflon thickness of piston 5 surface sprayings is 0.01mm.
The utility model in use, engine drives bent axle 7 rotatablely moves, bent axle 7 drives wrist pins 9 through connecting rod 10, thereby drives piston 5 motions, realizes that promptly rotatablely moving of bent axle 7 is converted into moving up and down of piston 5, thereby realizes compressed-air actuated purpose.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
