Description
Technical Field
The utility model relates to the technical field of compressor crankshafts, in particular to a reciprocating piston type refrigerator compressor crankshaft.
Background
The compressor is the core component of the refrigeration system, and the working efficiency of the compressor directly influences the performance of the refrigeration system. When the compressor works, the crankshaft is driven to rotate by the motor, the rotating crankshaft drives the connecting rod to reciprocate, and the reciprocating connecting rod pushes the piston to compress gas. Crankshafts are susceptible to wear during long periods of rotation and therefore require effective lubrication thereof.
But the lubricating oil at the connecting part of the existing crankshaft and the connecting part can not well enter, so that the actual lubricating effect is poor, the crankshaft is quickly abraded, and the service life is short.
Therefore, it is necessary to provide a crankshaft for a reciprocating piston refrigerator compressor to solve the above problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a reciprocating piston type refrigerator compressor crankshaft to solve the problems in the background technology.
In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a reciprocating piston refrigerator compressor bent axle, includes connecting axle, transmission shaft and two balancing weights that the symmetry set up, two the fixed connecting axle that is provided with in upper end between the balancing weight, the oil pocket has been seted up to the inside of connecting axle, the front of oil pocket and back inner wall both ends all run through and have seted up the oil inlet, the front of oil pocket and back inner wall middle part all run through and have seted up the oil outlet.
Preferably, the oil outlet holes are provided with a plurality of oil outlet holes which are distributed in a rectangular array.
Preferably, the oil inlet is obliquely arranged, and a transmission shaft is fixedly arranged in the middle of the outer side of the balancing weight.
Preferably, the inner walls of the two ends of the oil cavity are fixedly provided with stop blocks, and the stop blocks are arranged in a circular truncated cone shape.
The utility model has the technical effects and advantages that:
1. according to the utility model, through the arrangement of the oil cavity, the oil inlet and the oil outlet, when the connecting shaft rotates, engine oil can enter the oil cavity through the oil inlet and finally flows to the middle part of the outer side wall of the connecting shaft through the plurality of oil outlets, namely the connecting part of the connecting shaft and the connecting rod, so that a lubricating effect can be well played, the abrasion of the connecting shaft is reduced, and the service life of the crankshaft is prolonged;
2. according to the oil outlet structure, the check block is arranged, so that engine oil entering the oil cavity from the oil inlet can flow to the middle of the oil cavity, and can smoothly enter the oil outlet hole, and the engine oil is prevented from flowing out of the other oil inlet and cannot well flow into the oil outlet hole.
