Problems solved by technology

When the load pressure of the piston compressor is high, the oil lines thrown out from the upper oil hole and the oil groove are messy and many, and most of the oil lines will be thrown into the tail of the piston, resulting in a relatively large oil discharge volume of the piston compressor, which is easy to Reduce the oil volume during the operation of the piston compressor, which will cause the piston compressor to wear and even get stuck

Abstract

The invention discloses a crankshaft for a piston compressor and a piston compressor with the crank shaft. The piston compressor comprises a connecting rod and a piston connected at one end of the connecting rod, wherein the other end of the connecting rod is sleeved on the crankshaft. The crankshaft comprises a body, and the body comprises a long shaft segment and an eccentric shaft segment arranged at one end of the long shaft segment. An oil outlet groove is formed in the side wall of the eccentric shaft segment and does not penetrate through the end surface, far away from the long shaft segment, of the eccentric shaft segment. An oil outlet hole is formed in the eccentric shaft segment. One end of the oil outlet hole penetrates through the end surface of the eccentric shaft segment. The oil outlet groove is communicated with the oil outlet hole. The other end of the connecting rod is sleeved on the eccentric shaft segment and seals the oil outlet groove. The lubricating oil thrown from the oil outlet hole is thrown to a piston. The crank shaft for the piston compressor can improve the oil outlet volume of the piston compressor.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a crankshaft for a piston compressor and a piston compressor with the crankshaft. Background technique [0002] In the related art, the oil groove on the eccentric shaft of the crankshaft of the piston compressor penetrates through the eccentric shaft. When the load pressure of the piston compressor is high, the oil lines thrown out from the upper oil hole and the oil groove are messy and many, and most of the oil lines will be thrown into the tail of the piston, resulting in a relatively large oil discharge volume of the piston compressor, which is easy to The oil volume during the operation of the piston compressor is reduced, which will cause the piston compressor to wear and even get stuck. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the present inventi...
