Oil-free pendulum type air compressor

Abstract

The invention relates to an oil-free pendulum type air compressor, which prolongs the working time, reduces the temperature of lubricating oil for a transmission mechanism by 20 DEG C, changes an air inlet flue from a single cavity to double cavities, reduces pulse action, and greatly improves the service life of components. The oil-free pendulum type air compressor comprises a body shell, a crank case, a connecting rod, a rotor, a cylinder, a valve, a sensor and a belt pulley. A crank shaft is arranged on the body shell; the connecting rod is arranged on the crank shaft; the other end of the connecting rod is arranged at one end of a shaft of the rotor; the rotor is arranged in the cylinder; and one end of the crank shaft is provided with the belt pulley, and the other end of the crank shaft is provided with sensor shaft of a sensor motor. The oil-free pendulum type air compressor is characterized in that the connecting rod is arranged on the crank shaft through a pin shaft; a rolling bearing is arranged between the connecting rod and the pin shaft; a plurality of concave parts are evenly distributed on the connected end surface of a connector between the cylinder and the body shell; and the cylinder and the body shell are reserved with an air inlet respectively, and the front end of the air inlet is provided with an air filter. The oil-free pendulum type air compressor is applicable to a cement bulk truck, and also can be used for other devices.

Description

Technical field: [0001] The invention relates to the technical field of air compressors, in particular to an oil-free pendulum air compressor. Background technique: [0002] The transmission device of the oil-free pendulum air compressor used in cement bulk trucks is of the connecting rod bearing type, mainly composed of connecting rods, crankshafts, connecting rod body bearing sleeves, bearing bushes, oil pumps, gears, bevel gears and other components. Driven by the driving force of the automobile engine or the engine, the crankshaft, connecting rod, and rocker arm are driven by the V-belt to make the pendulum swing back and forth in the inner seat of the cylinder, thereby generating working power. The crankshaft of this transmission device is lubricated by bearing bushes. The oil pump needs to be used for oil injection, and the oil pump needs to be connected with gears and bevel gears to work. [0003] The defects of this device are: 1. Due to the large friction surface o...

AI Technical Summary

Problems solved by technology

[0003] The defects of this device are: 1. Due to the large friction surface of the bearing bush, high working temperature, and easy "burning", the continuous working time can only be about 60 minutes, and the noise is relatively large; Fill the bearing bush with oil when rotating, so the transmission device can only rotate forward and cannot reverse, so that the installation and use are limited
