Problems solved by technology
When these centrifugal forces are superimposed, and the distance from the end point of the crankshaft supported by the main bearing to the balance weight is relatively long, the resultant moment is relatively large
This will intensify the contact wear between the crankshaft of the compressor and the main bearing, and in severe cases, large-area wear of the main bearing will occur

The invention discloses a horizontal compressor, which belongs to the field of compressor construction. The horizontal compressor includes a housing, a cylinder assembly, a crankshaft, a drive motor, a piston and a balance weight. The cylinder assembly is arranged in the housing and defines a compression cavity in the cylinder assembly. The crankshaft runs through the cylinder assembly, and the crankshaft has an eccentric portion, and the eccentric portion is located in the compression chamber. The driving motor is arranged in the housing for driving the crankshaft to rotate around its central axis. The piston is sleeved on the outside of the eccentric part. The balance weight is used to balance the piston and the eccentric part, and the balance weight is sleeved on the end of the crankshaft away from the drive motor. The horizontal compressor of the present invention can well reduce the deflection of the crankshaft, reduce the abrasion of the crankshaft, and reduce the vibration and noise during operation of the horizontal compressor by arranging the balance weight at the end of the crankshaft away from the drive motor. Improve the reliability of the horizontal compressor.
Description
technical field [0001] The invention relates to the field of compressor construction, in particular to a horizontal compressor. Background technique [0002] In a traditional horizontal compressor, a balance block is generally arranged on the end face of the motor rotor to balance the eccentric mass generated by the eccentric shaft of the crankshaft and the piston. Since the rotor is fixed at one end of the crankshaft, this model can be imagined as a transverse cantilever beam structure. At the same time, due to the existence of the imbalance between the stator and the rotor, the motor will generate magnetic pull when the compressor rotates, and the rotor will also generate due to its own weight when the compressor rotates. Centrifugal force, in addition, the balance weight will also generate a corresponding centrifugal moment when it rotates. When these centrifugal forces are superimposed, and the distance from the end point of the crankshaft supported by the main bearing ...
