Problems solved by technology

The above-mentioned movement mode of the connecting rod causes the force that the connecting rod acts on the piston through the piston pin to be a constantly changing swinging force, which undoubtedly brings some disadvantages: firstly, it causes the piston to slap the cylinder when it is working. It leads to greater noise; secondly, it causes the piston to generate greater side pressure and friction on the cylinder, which increases the power consumption of the compressor and shortens its life

Abstract

The invention belongs to the technical field of piston compressors and relates to a low-noise reciprocating piston compressor, comprising a motor, a piston body, a connecting rod, a cylinder and an air inlet and output device. The cylinder is connected on a transmission box body which is internally provided with a deceleration transmission gear; a spindle of the motor is connected to an input shaft of the deceleration transmission gear; an output shaft of the deceleration transmission mechanism is provided with a first eccentric shaft which is rotatably sleeved with a planetary gear; the transmission box is internally provided with a stationary gear; the planetary gear is engaged with the stationary gear; the planetary gear is provided with a second eccentric shaft; one end of the connecting rod is sleeved on the second eccentric shaft of the planetary gear; and the other end of the connecting rod is connected with the piston body. The invention has long piston stroke, little vibration, low noise, low exhaust temperature and long service life, and is suitable for producing pump bodies such as various types of reciprocating piston-type hydraulic pumps, vacuum pumps and cold air pumps or compressors.

Description

technical field [0001] The invention belongs to the technical field of piston compressors, in particular to a low-noise reciprocating piston compressor. Background technique [0002] At present, most reciprocating piston compressors include hydraulic pumps, water pumps, vacuum pumps and air-conditioning pumps. Movement, so as to realize the periodic change of the working volume in the cylinder. Obviously, the traditional reciprocating compressor uses a typical crank-connecting rod structure. Since the connection between the crankshaft and the connecting rod is to insert the crankshaft directly into the connecting hole of the big end of the connecting rod, and the small end of the connecting rod is connected to the piston through the piston pin. In this way, the movement of the connecting rod is essentially a planar movement: on the one hand, the big head of the connecting rod rotates in a circle with the crankshaft; . The above-mentioned movement mode of the connecting ro...
