Problems solved by technology
The existing crankshaft assembly is mainly designed for the forward rotation of the compressor. The connection design of the crankshaft oil pump system and the crankshaft and connecting rod does not consider the installation and fixation of the eccentric bushing. Insufficient pump oil, serious wear of the crankshaft, serious wear of the mounting surface of the eccentric bushing, increased energy consumption of the compressor, etc.

The invention discloses a crankshaft assembly, a compressor and refrigeration equipment. The axis of the eccentric shaft of the crankshaft assembly is parallel to the axis of a main shaft; the oil outlet of the eccentric shaft is communicated with the second through hole of the main shaft through the oil guide groove of an oil guide plate; a main spiral oil pump is arranged in the cavity of the main shaft; and one end of a second spiral oil groove is communicated with the oil guide groove. When the crankshaft assembly rotates in a first direction, oil entering the cavity of the main shaft sequentially passes through a first through hole, a first spiral oil groove, the second through hole and the oil guide groove and is finally discharged from the oil outlet. When the crankshaft assembly rotates in a second direction opposite to the first direction, the oil entering the cavity of the main shaft sequentially passes through the second spiral oil groove and the oil guide groove and is finally discharged from the oil outlet. The crankshaft assembly can ensure a sufficient oil pumping amount during forward rotation and reverse rotation, and is simple to machine.
Description
technical field [0001] The invention relates to the technical field of compressors, in particular to a crankshaft assembly, a compressor and refrigeration equipment. Background technique [0002] The fully enclosed reciprocating refrigeration compressor is the core component of small refrigeration equipment such as refrigerators and freezers. The crankshaft, as the main rotating part of the reciprocating variable capacity refrigeration compressor, carries the mission of safe operation of the entire compressor. The existing crankshaft assembly is mainly designed for the forward rotation of the compressor. The connection design of the crankshaft oil pump system and the crankshaft and connecting rod does not consider the installation and fixation of the eccentric bushing. Insufficient pump oil, serious wear of the crankshaft, serious wear of the mounting surface of the eccentric bushing, and increased energy consumption of the compressor.
