Abstract
The invention relates to the technical field of compressors, in particular to a compressor crankshaft. The compressor crankshaft comprises a body, an eccentric part, a first oil-way, a second oil-way and an oil chamber. The eccentric part is disposed above the body. The first oil-way and the second oil-way are arranged on the body. The oil chamber is disposed in the eccentric part. A positioning groove is arranged at the tail end of the second oil-way. An oblique oil hole is reserved on the oil chamber. The compressor crankshaft is high in universality, compact in structure, simple to operate, safe, reliable, convenient to mount and machine and high in precision, probability in friction between the crankshaft wall and an engine during operation of a compressor is reduced, and accordingly, friction coefficient is reduced, output power is lowered, overall performance of the compressor is improved, service life of the compressor is improved, and popularization and application are easy.
Description
Technical field
The present invention relates to a kind of technical field of compressor, especially a kind of compressor crank shaft.
Background technique
The crankshaft structure of existing compressor easily causes being difficult to stablize oil-feed, and the precision of installing and processing is difficult to assurance, and simultaneously, the friction factor of bent axle wall and body is larger, has strengthened output power, has reduced the performance of complete machine, has shortened the working life of compressor.
Summary of the invention
Existing compressor operating performance is difficult to stablize in order to overcome, output power large and compressor short deficiency in working life, the invention provides a kind of compressor crank shaft.
The technical solution adopted for the present invention to solve the technical problems is: a kind of compressor crank shaft, comprise axis body, eccentric part, the first oil circuit, the second oil circuit and grease chamber, the axis body top is provided with eccentric part, and axis body is provided with the first oil circuit and the second oil circuit, is provided with the grease chamber in the eccentric part.
According to another embodiment of the invention, comprise that further the second oil circuit end is provided with locating slot.
According to another embodiment of the invention, comprise that further the grease chamber is provided with inclined oil hole of air.
The invention has the beneficial effects as follows this compressor crank shaft highly versatile, compact structure, simple to operate, safe and reliable, to install and process more convenient, ratio of precision is higher, reduced compressor friction probability between bent axle wall and the body when operation, thereby reduced friction factor, reduced output power, improved the performance of complete machine, prolonged the working life of compressor, be easy to apply.
