Abstract

The invention discloses an oiling structure for a compressor crankshaft, which relates to the technical field of compressors. The crankshaft oiling structure of the compressor includes the main shaft of the crankshaft and the rotor connected to the crankshaft. The surface of the main shaft is provided with an oil supply passage through its axial direction; it also includes a shaft sleeve installed on the shaft of the rotor. In the hole, and sleeved on the lower end of the main shaft, an oil supply passage is formed between the main shaft, the sleeve and the rotor. At the same time, it also discloses a compressor oil circuit structure and a compressor with the above compressor crankshaft oiling structure. The invention solves the problem of difficult machining of the inclined oil hole of the crankshaft, reduces the processing steps, reduces the processing cost of the product, and reduces the risk of blockage of the oil passage caused by burrs caused by improper drilling and processing of the crankshaft. quality control.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor crankshaft oiling structure, a compressor oil circuit structure and a compressor having the compressor crankshaft oiling structure. Background technique [0002] Currently, if figure 1 As shown, the crankshaft oil circuit structure generally adopted by piston compressors with small diameter crankshafts is as follows: through the centrifugal force of the crankshaft rotation, the lubricating oil enters the crankshaft along the oil inclined hole 1' on the lower end of the crankshaft, passes through the main shaft lubricating oil hole 2', and the main shaft lubricating oil The oil hole 4' and the helical oil groove 3' are oiled to lubricate the crankshaft main shaft. The part from the main shaft of the crankshaft to the crank is lubricated through the inclined hole 5' leading to the top of the crankshaft. After the lubricating oil reaches the crankshaft, part of it ...
