Background
In the existing crankshaft connecting rod piston transmission mechanism used for the engine and the compressor, the piston has side thrust and a piston skirt part and a piston pin are required, so that the piston has large mass, large inertia force and poor sealing. The friction loss of the piston is 12% of the output power of the shaft, the connecting rod bears the upper and lower thrust and inertia force at the same time, and the connecting rod bears the additional bending force caused by the motion inertia force of the connecting rod in the swinging plane of the connecting rod, so that the manufacturing quality is increased, and the connecting rod must resist fatigue and impact, and have sufficient strength and rigidity, especially bending resistance. The link length should not be too long to resist bending.
The friction loss of the big and small ends of the connecting rod and the bearing of the output shaft reaches 18 percent of the power of the output shaft, the crankshaft bears the unidirectional thrust, the pulling force, the reciprocating inertia force and the centrifugal force of the connecting rod, and the serious stress concentration phenomenon is generated around the oil hole; torsional, transverse and longitudinal vibrations are generated under the action of radial forces, tangential forces and torque. When the natural frequency of the crankshaft is low, resonance may occur within the operating speed of the engine, which greatly increases the amplitude and generates a large negative stress.
The torsional vibration will cause the noise and fatigue of the transmission gear, leading to the deterioration of the working process, and the transverse vibration will aggravate the abrasion of the shaft neck and the bearing because of the overlarge bending of the crankshaft, even the normal work can not be carried out, and the output power is reduced.

when external power is applied to the main shaft of the straight-rod piston seven-wheel transmission mechanism, the piston head 1 does up-and-down reciprocating motion and does work outwards, when the piston head moves downwards, the pressure in the cylinder 18 is smaller than the pressure outside the cylinder 18, the air inlet valve 20 is opened in the stroke, the air outlet valve 21 is closed, and external air enters the cylinder 18; when the piston head moves upwards, the air inlet valve 20 is closed, the air outlet valve 21 is opened, air is compressed and discharged out of the air cylinder 18, and when the piston head 1 moves upwards to the limit position, the air outlet valve is closed; when the piston head 1 descends again, the processes are repeated, wherein the straight rod piston seven-wheel transmission mechanism rotates for a circle, the piston head 1 reciprocates up and down once, and the processes of air inlet, compression and air exhaust sequentially occur in the air cylinder 18 and a cycle is completed. According to the requirement, the straight rod piston seven-wheel transmission mechanism can be made into a hydraulic machine, an oil press, an air compressor, a vacuum pump, a water pump and a compressor.
Specifically, when the compressor manufactured by the invention is used, oil can enter and exit the hydraulic cylinder 15 in real time through the first servo valve 14 and the second servo valve 14-1 through the electric control unit, so that the compression ratio of the compressor is controlled in real time.
