Problems solved by technology

The stator and rotor of the motor of the horizontal compressor are horizontal, and the rotor is in an unsupported cantilever state for a long time under the action of gravity, such as figure 1 and figure 2 As shown, it is often necessary to add a balance weight c to the motor rotor b at the other end of the crankshaft a to balance. Even so, it will cause a certain degree of eccentric wear on the side end surface of the main bearing d when starting or running, and the noise and vibration are eccentric. Large, affecting the reliability of the compressor

Abstract

The present invention discloses a horizontal compressor having symmetrical double cylinders. The horizontal compressor comprises a housing, a motor and a crankshaft, wherein the crankshaft is assembled on a rotor of the motor, the motor of the compressor is sealed inside the housing, a first compression unit and a second compression unit are respectively and symmetrically arranged inside the housing on both ends of the motor,and are driven by a left end portion and a right end portion of the crankshaft, the crankshaft comprises a linear main shaft and a pair of eccentric shaft sleeves, and the eccentric shaft sleeves are symmetrically arranged on both ends of the main shaft by adopting the axis core line of the main shaft as the center line.

Description

【Technical field】 [0001] The invention relates to horizontal compressor equipment, in particular to a horizontal compressor with symmetrical double cylinders. 【Background technique】 [0002] The horizontal rotary compressor in the prior art is widely used in application systems such as refrigerators and air conditioners due to its low center of gravity and low vibration. The motor stator and rotor of the horizontal compressor are horizontal, and the rotor is in an unsupported cantilever state for a long time under the action of gravity, such as figure 1 and figure 2 As shown, it is often necessary to add a balance weight c to the motor rotor b at the other end of the crankshaft a to balance. Even so, it will cause a certain degree of eccentric wear on the side end surface of the main bearing d when starting or running, and the noise and vibration are eccentric. Large, it will affect the reliability of the compressor. 【Content of invention】 [0003] The invention adopts...
