Abstract
The invention discloses a crankshaft for a compressor. The crankshaft comprises an eccentric part, a transition element and a shaft body, wherein an oil chamber is formed in the eccentric part; a first threaded column is arranged at the bottom end of the eccentric part, and a first oil conduit is arranged in the first threaded column; a first threaded hole is formed in the upper surface of the transition element, a second threaded hole is formed in the center of the lower surface of the transition element, and an oil duct is formed between the first threaded hole and the second threaded hole; a second threaded column is arranged at the top end of the shaft body, a second oil conduit is arranged in the second threaded column, a spiral oil groove and a linear oil groove are formed in the shaft body and are connected, and the spiral oil groove is connected with the second oil conduit. According to the scheme, the crankshaft for the compressor adopts a combined structure, is high in universality and simple in structure and can adopt separate processing, so that the processing is more convenient, the precision is higher, and meanwhile, local replacement can be realized, and the cost is saved.
Description
Technical field
The present invention relates to compressor field, particularly relate to compressor bent axle.
Background technique
Bent axle is the power-transmitting part of piston compressor, the extrinsic motives such as motor by bent axle by transmission of power to compressor, and bent axle drives another compressor part---connecting rod mounted thereto, and rotation motion is converted into to-and-fro motion, thus realizes the work of piston compressor.
The crankshaft structure of existing compressor easily causes being difficult to stable oil-feed, and the precision of installing and processing is difficult to ensure, meanwhile, bent axle wall is larger with the friction factor of body, increases output power, reduces the performance of complete machine, shortens the working life of compressor.
Summary of the invention
The technical problem that the present invention mainly solves is to provide compressor bent axle.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: compressor bent axle, comprising: eccentric part, transition element and axis body, and described eccentric part, described transition element are connected successively with described axis body;
Be provided with accumulator in described eccentric part, described eccentric part bottom is provided with the first screw column, is provided with the first oil guide pipe in described first screw column;
Described transition element upper surface offers the first tapped hole, and the lower surface center of described transition element offers the second tapped hole, is provided with oil duct between described first tapped hole and described second tapped hole;
Described axis body top is provided with the second screw column, the second oil guide pipe is provided with in described second screw column, described axis body offers spiral helicine oil groove and linear oil groove, described spiral helicine oil groove is connected with described linear oil groove, and described spiral helicine oil groove is connected with described second oil guide pipe.
In a preferred embodiment of the present invention, described first screw column and described first corresponding threaded holes close.
In a preferred embodiment of the present invention, described second screw column and described second corresponding threaded holes close.
The invention has the beneficial effects as follows: compressor bent axle of the present invention, this bent axle adopts composite structure, highly versatile, and structure is simple, can separate machined, and make processing convenient, precision is also higher, simultaneously can local replacing, has saved cost.
