Problems solved by technology

However, the movement direction of the piston of the swash plate compressor is a reciprocating linear motion in the axial direction of the compressor drive shaft. The driving principle is to use the periodic change in the axial direction of the swash plate surface due to rotation to transmit to the piston. In this way, the piston is pushed to make a reciprocating linear motion in the axial direction of the transmission shaft. The force transmission process is more complicated, and the direction of the force has been changed several times. When the transmission shaft outputs the same torque, the swash plate compressor reaches the piston connecting rod. The torque for driving the piston to do reciprocating linear motion is small, and the power loss is large, so the efficiency of the swash plate compressor is low, and the input power is usually required to be large

Abstract

The invention provides a novel rotary compressor, which includes a motor, a transmission shaft and a compressor airtight casing. The motor is arranged outside the compressor airtight casing and drives an eccentric wheel through the transmission shaft. An annular connector is arranged on the outer edge of the eccentric wheel to make the ring The connector can move correspondingly with the rotation of the eccentric wheel and can slide relative to the outer edge of the eccentric wheel. At least two sets of cylinder-piston assemblies are fixed in the airtight casing of the compressor. Each set includes a cylinder, a piston, and a piston connecting rod. Both ends of the piston connecting rod They are respectively hinged with the piston and the ring connector, and the ring connector drives the piston to make a reciprocating linear motion in the cylinder. Each cylinder wall is provided with an air intake hole and an exhaust hole, and is connected with the outside of the cylinder with a one-way valve device respectively. The technical scheme has a simple transfer process from the rotary motion to the linear motion of the piston, and the power output-to-input ratio is larger.

Description

Technical field [0001] The invention relates to a rotary compressor, in particular to a rotary compressor that converts a rotary motion mode into a piston reciprocating linear motion mode. Background technique [0002] Currently commonly used compressors include swash plate, scroll, screw and other types. Most compressors seal the motor as a whole in the compressor shell due to the need for the compressor to be hermetically sealed, which is not conducive to heat dissipation, but also brings inconvenience to the internal repair and maintenance of the compressor. The swash plate compressor is similar in structure to the technical solution of this patent. It converts the rotational motion of the drive shaft into the reciprocating linear motion of the piston through the swash plate. The rotational power of the drive shaft comes from outside the sealed casing, which is more common in automobiles. air conditioning. However, the movement direction of the piston of the swash plate comp...
