Problems solved by technology

So, when the setting of the connecting rod body relative to the crankshaft axis is not stable, it will cause friction and wear to every part of the compressor
As a result, the compressor cannot be driven normally
This problem is especially serious when the crankshaft and piston are mechanically misaligned

Abstract

The invention discloses a closed reciprocating compressor which comprises a motor arranged in a closed container, a cylinder, a piston freely sliding along the inner wall of the cylinder, a crank shaft conducting the rotating force of the motor, and a connecting bar body device, wherein the upper part of the crank shaft is provided with an eccentric part; the connecting bar body device is connected with an eccentric part pivot shaft of the crank shaft and is connected with the pivot shaft of the piston so as to lead the rotation of the crank shaft to be converted into reciprocating linear motion of the piston relative to the cylinder. The closed reciprocating compressor is provided with a globe bearing at one end of a connecting bar body, which is connected with the crank shaft, and a preset expansion joint is formed between connecting parts, thereby leading the big diameter part of the connecting bar body and the globe bearing to oppositely rotate so that the verticality between the connecting bar body and the crank shaft is automatically regulated through the rotation. The invention can effectively solve the problem that the axle line of the crank shaft is not vertical to the axle line of the piston, lowers the friction and the abrasion of various mechanical connecting relations based on the connecting bar body and maintains the normal operation of the compressor.

Description

technical field [0001] The invention relates to a hermetic reciprocating compressor. Background technique [0002] A typical hermetic compressor includes a motor unit, a frame, a crankshaft, a connecting rod body, a cylinder and a piston. Wherein, the motor unit has a stator and a rotor, and the rotor is rotatably mounted near the stator. The lower part of the crankshaft is fixed at the center of the rotor, and the upper part has an eccentric part, which rotates with the rotor. The connecting rod body is connected between the piston and the eccentric part of the upper part of the crankshaft. The eccentric part of the upper part of the crankshaft is inserted into a cylindrical hole opened on a large diameter part at one end of the connecting rod body to be rotatably connected. The piston is connected to the connecting rod through the piston pin. The small diameter portion at the other end of the rod body is connected, and the piston moves linearly back and forth in the cyli...
