Description
Technical Field
The utility model relates to the field of compressors, in particular to a main shaft oil supply structure of a compressor.
Background
At present, an electric scroll compressor in the market drives a main shaft by a motor to drive a compression cavity to compress gaseous refrigerant, and along with the design of the compressor, the maximum rotation speed is higher and higher, so that the full lubrication among parts in the compressor is particularly important.
Most of compressors in the market mainly rely on gaseous refrigerants to drive lubricating oil to the surfaces of all parts to lubricate, and the lubricating mode cannot fully enable the lubricating oil to circulate in the compressor, so that the lubricating effect is poor, and larger abrasion occurs between the parts, and the service life of the compressor is seriously influenced, so that a set of main shaft oil supply mechanism is developed to increase the oil circulation rate.
Disclosure of Invention
In view of the foregoing, the present utility model is directed to a compressor main shaft oil supply structure.
In order to achieve the technical purpose, the scheme of the utility model is as follows: the utility model provides a compressor main shaft oil supply structure, includes the main shaft, the main shaft is connected with the volumetric pump to and the oil supply structure that sets up in the main shaft, oil supply structure comprises first oil spout, second oil spout and lubricating oil runner, first oil spout, second oil spout communicate in lubricating oil runner.
Preferably: the positive displacement pump is a closed working space consisting of a main shaft, a shell groove and an oil seal cover.
Preferably: the cylinder body bearing is sleeved outside the left end of the main shaft, the main bearing is sleeved outside the right end of the main shaft, the first oil spraying port is correspondingly arranged on the cylinder body bearing, and the second oil spraying port is correspondingly arranged on the main bearing.
Preferably: the main shaft, the first oil spraying port and the second oil spraying port are hollow, and the lubricating oil runner is arranged in the hollow structure of the main shaft.
The utility model has the advantages that,
the main shaft drives the displacement pump to operate when moving, presses lubricating oil into the runner, and under the action of centrifugal force, the lubricating oil is thrown out from the positions of the first oil injection port and the second oil injection port respectively, the first oil injection port supplies lubrication to the cylinder body bearing, and the second oil injection port supplies lubrication to the main bearing, so that the cylinder body bearing and the main bearing can be lubricated, the internal circulation of the lubricating oil in the compressor is realized, the lubricating effect is good, the abrasion among parts is reduced, and the service life of the compressor is prolonged.
