Abstract
The utility model relates to a rolling rotary-piston gas compressor which comprises an outer shell 1, a cylinder sleeve 2, a piston 3, an eccentric shaft 4, an air inlet 5 and an air outlet 6. The utility model causes the dynamic force to be directly input into the eccentric shaft, and each pair of eccentric wheels which differ by 180 DEG in eccentric direction are driven by the dynamic force to drive the corresponding pistons and cylinder sleeves to roll and rotate together. Each pair of pistons and cylinder sleeves respectively use the same air inlet and air outlet, and the switching of air input, compression and air exhaust are automatically realized without a group of air exhaust valves and valve plates. The utility model does not require balance components, and the relative speed is low, so that the noise and the vibration are reduced. The utility model has simple processing technology of the components, and can use universal equipment for bulk production so as to reduce product cost.

At present, common gas compressor mainly is made of bent axle, connecting rod, piston or eccentric shaft piston.The gas compressor of this structure all must be equipped with parts such as air inlet and exhaust valve group, valve block, balance iron, thereby causes noise big, and moment is difficult to balance, and power consumpiton and vibration are all bigger.
Summary of the invention
The purpose of this utility model provides that a kind of noise is little, the easy balance of moment, power consumpiton and all less gas compressor of vibration.
The utility model comprises shell, cylinder sleeve, piston, eccentric shaft, suction port, relief opening; Establish cavity in the shell, suction port, relief opening are arranged on the shell, and perforation cavity, cylinder sleeve is arranged in the cavity of shell, and its outer wall and cavity inner wall also are provided with on the cylinder sleeve and traverse logical piston hole movingly, piston wherein is housed, piston outer wall and piston hole inwall movingly, piston is provided with eccentric opening, the eccentric opening that eccentric shaft passes on the piston is arranged on the shell.
Described eccentric shaft is provided with eccentric wheel, and is positioned in the eccentric opening of piston, and the two ends of eccentric shaft are connected the two ends of shell by bearing and bearing support.
Described cylinder sleeve is provided with at least one pair of and traverses logical piston hole, the axis of every pair of piston hole is orthogonal, be respectively equipped with piston in every pair of piston hole, pass on the eccentric shaft of every pair of piston eccentric opening and be equipped with a pair of eccentric wheel, this a pair of eccentric eccentric direction differs 180 °, and is positioned respectively in the eccentric opening of piston.
Described eccentric shaft and eccentric centripetal moment O
1O
2Equal the centripetal moment OO of eccentric shaft and cylinder sleeve axis
1Formed compression stroke is 4 times of centripetal moment, and the rotating speed of piston, cylinder sleeve is half of eccentric shaft.
In the real work, the utility model is directly inputted to eccentric shaft with power, driving eccentric direction by it differs each of 180 ° eccentric wheel is driven the rotation of rolling jointly of corresponding piston, cylinder sleeve, and every pair of piston, cylinder sleeve use same porting respectively jointly, and realize automatically the switching of air inlet, compression, exhaust need not outlet valve group, valve block.
The utility model need not equalizing feature and relative rotation speed is lower, thereby noise, vibration reduce.Component processing technology of the present utility model is simple, uses standard equipment to produce in batches, thereby has reduced product cost.
