Problems solved by technology
[0005] It can be seen from the above that the structure of the crankshaft plays a vital role in the assembly and operation stability of the compressor, especially for the three-stage compressor, in order to reduce the balance of the compressor as much as possible, the eccentric circle of the crankshaft generally adopts 120° ° Evenly distributed, the distribution of eccentric circles has caused serious assembly problems. The eccentric circle of the crankshaft in the middle cannot be inserted into the roller due to the obstruction of the upper and lower eccentric circles, which has brought great difficulties to the assembly of the compressor.

The invention discloses a compressor crank shaft convenient to install. The compressor crank shaft convenient to install comprises a main shaft and an eccentric circular ring detachably arranged on the main shaft. An installation table protruding outwards is arranged at a position, corresponding to the eccentric circular ring, on the main shaft; a fixing slot is formed in the installation table; afixing block capable of axially moving along the eccentric circular ring is arranged at a position, corresponding to the fixing slot, on the eccentric circular ring; and one end of the fixing block is embedded into the fixing slot. The compressor crank shaft convenient to install provided by the invention is reasonable in structure design and convenient and fast to use, components are prevented from being scattered and lost, worn or damaged components can be locally replaced, and the waste is avoided.
Description
technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor crankshaft which is easy to install. Background technique [0002] Generally speaking, a rotary compressor is composed of a motor part and a compressor part. The motor rotor of the motor part is set in the central cavity of the annular stator formed by the iron core and windings. There is a crankshaft in the center of the rotor, and the lower end of the crankshaft is connected to the compressor. department. The compressor part mainly includes the rolling piston connected to the crankshaft and the compressed cylinder contained therein. The cylinder is closed by an upper bearing and a lower bearing and an annular cylinder wall fixedly combined on the compressor sealing shell between the upper bearing and the lower bearing. made. The crankshaft of the rotor of the motor part passes through the upper bearing and enters the compression cylinder, and the lower end of...
