Abstract

The utility model discloses a revolver compression engine and belongs to a revolver displacement compressor, comprising an eccentric shaft (a bell crank and a cam) and a compensating block; a rolling bearing is arranged on the eccentric shaft; the fixed adjustment casing of the outer ring of the rolling bearing forms a rotor which can rotate in an air cylinder. The air cylinder is divided into a compressing cavity and a suction chamber through a sliding blade and a rotor. The gas directly enters the suction chamber after the mechanical impurity is removed through a cleaning cartridge; the compressed gas is discharged through a discharge valve. The abrasion and the friction are reduced by a rotor structure; the compressed function with oil-free lubrication is provided; the energy is saved; the raw material and the oil material can be saved.

Description

Revolver compression engine

The utility model is a kind of rotary compressor, belongs to the rotary positive displacement compressor scope, is applicable to the compression and the suction of gas, is particularly useful for the compression of oil-free lubrication gas.

Some rotary positive displacement compressors that use drive eccentric rotor by main shaft and make eccentric motion in cylinders at present, by slide plate and rotor cylinder are divided into suction chamber and compression chamber, and gas is sucked from suction port, discharge from expulsion valve.No matter adopt rotary slide sheet, eccentric cam adds flip sleeve, and because of linear velocity is big, quick abrasion still can adopt in the occasion that oil lubrication is arranged, but air displacement can not be big, because of the need oil lubrication, and dusty gas, its application area is very narrow.For extremely, the oil-free lubrication rotary positive displacement compressor is not arranged as yet up till now.Now, non-lubricated compressor adopts reciprocal positive displacement compressor mostly, and back and forth positive displacement compressor exists complex structure, and efficient is lower, and inconvenient maintenance consumes shortcomings such as oil plant.

The purpose of this utility model is exactly in order to solve the deficiency of above-mentioned existence, provide a kind of simple in structure, efficient is high, energy-conservation, fuel-economizing, the consumption that saves material, and can be at the rotary positive displacement compressor of oil-free lubrication situation lower compression gas.

The utility model is implemented by following technical solution, will be changed into by rolling bearing, be regulated overcoat by the eccentric rotor that main shaft drives, and arranges the compensation block composition on two limits of rolling bearing.The high speed rotary motion is born by rolling bearing, significantly reduce wear and rub.Regulating only to have between overcoat and the slide plate to move up and down on a small quantity and swing reduces wearing and tearing.Slide plate and rotor are divided into suction chamber and compression chamber with cylinder, and gas sucks from suction port and discharges behind expulsion valve.Finish gas compression or pumping action.

Accompanying drawing is described an embodiment of the present utility model.

It is the shaft section schematic representation of model utility internal structure that Figure 1A-A analyses and observe

It is the cross sectional representation of model utility internal structure that Fig. 2 B-B analyses and observe

Below by accompanying drawing embodiment of the present utility model is done more detailed introduction.The throw of eccentric of rotation is provided by eccentric shaft 7, eccentric shaft can be by crank throw, adorns mode such as eccentric garden cam on the axle and implements, and rolling bearing 3 and compensation block 2 and 4 are housed on eccentric shaft, at housing washer secured adjusted overcoat 8, constitute rotor (this assembly is unnumbered) and can bear high speed rotary motion.Significantly reduce friction and wear and tear and can reduce slide plate wearing and tearing nationality and help slide plate 10, spring 11, front panel 1, rearmounted plate 5, make rotor that cylinder is divided into suction chamber and compression chamber, gas sucks from suction port by purifier 13, is discharged by exhaust joint 17 through expulsion valve 16, sealing 6 is set in the rearmounted plate prevents external leakage.By locating stud 12, screw 14, nut 15 unifies front panel, cylinder, rearmounted plate.The extension part tap coupling and the power of eccentric shaft obtain power and rotatablely move.

The utlity model has no glossy sliding pressure contracting, the function of peace and quiet gas is provided, wearing and tearing are few, and are energy-conservation. And have the ability to replace the field that is occupied by reciprocal positive displacement compressor at present, reaching energy-conservation big, the consumption that saves material is many, saves lubrication oil consumption.
