Abstract
The utility model relates to the technical field of compressors, in particular to a compressor crankshaft. The compressor crankshaft comprises a shaft body, an eccentric part, a first oil way, a second oil way and an oil chamber. The eccentric part is arranged above the shaft body, and the first oil way and the second oil way are arranged on the shaft body. The oil chamber is arranged in the eccentric part, a location groove is arranged at the tail end of the second oil way, and an inclined oil hole is arranged on the oil chamber. The compressor crankshaft is strong in generality, compact in structure, easy to operate, safe, reliable, convenient to install and process, and high in accuracy. In addition, by means of the compressor crankshaft, friction probability between a crankshaft wall and a compressor body during operation of the compressor is reduced, and accordingly friction coefficient is reduced, output power is lowered, property of the whole compressor is improved, and service life of the compressor is prolonged. Therefore, the compressor crankshaft is easy to popularize and apply.
Description
Technical field
The utility model relates to a kind of technology of compressors field, especially a kind of compressor crank shaft.
Background technique
The crankshaft structure of existing compressor causes being difficult to stablize oil-feed easily, and the precision of installing and processing is difficult to guarantee that simultaneously, the friction factor of bent axle wall and body is bigger, has strengthened output power, has reduced machine performance, has shortened the working life of compressor.
The model utility content
Existing compressor operating performance is difficult to stablize, output power is big and the deficiency of compressor weak point in working life in order to overcome, and the utility model provides a kind of compressor crank shaft.
The utility model solves the technological scheme that its technical problem adopted: a kind of compressor crank shaft; Comprise axis body, eccentric part, first oil circuit, second oil circuit and grease chamber; The axis body top is provided with eccentric part, and axis body is provided with first oil circuit and second oil circuit, is provided with the grease chamber in the eccentric part.
According to another embodiment of the utility model, comprise that further the second oil circuit end is provided with locating slot.
According to another embodiment of the utility model, comprise that further the grease chamber is provided with inclined oil hole of air.
The beneficial effect of the utility model is, this compressor crank shaft highly versatile, and compact structure, simple to operate; Safe and reliable, to install and process more convenient, ratio of precision is higher; Reduce compressor friction probability between bent axle wall and the body when operation, thereby reduced friction factor, reduced output power; Improved machine performance, prolonged the working life of compressor, be easy to apply.
