Abstract
The utility model discloses a compressor piston, including the piston only, run through on the piston only and be equipped with the piston pin hole, be equipped with the oil groove on the outer wall of piston only, be equipped with the connecting rod connecting hole on the inner wall of piston only, intermural formation segmental cavity in connecting rod connecting hole both sides and the piston only. The utility model provides a compressor piston, this piston through the increase oil reserve with reduce weight, not only strengthened the lubrication between compressor piston and the cylinder hole, reduced the friction between compressor piston and the cylinder hole, sealed effect is better, has reduced compressor operating noise moreover, has prolonged the life of piston, makes the compressor operating power reduce simultaneously, low pressure start -up easily.
Description
Technical field
The utility model belongs to piston technical field, is specifically related to a kind of refrigeration compressor piston.
Background technology
Refrigeration compressor drives piston through crankshaft-link rod, realize piston to-and-fro movement in the cylinder, reach compression effect, existing refrigeration compressor piston coordinates area very big with cylinder, if oil addition is less or do not have oil addition or place for a long time because of compressor in assembling process, micro lubricating oil film in cylinder and refrigeration compressor piston play flows out because of self gravitation, refrigeration compressor piston and cylinder holes lubrication are insufficient, its frictional force increase produced can cause compressor operating power big, low voltage starting difficulty does not even start, refrigeration compressor piston and cylinder friction expanded by heating can cause compressor stuck time serious, on the contrary, if lubricating oil too much can cause again waste, increase cost.
The both ends of the surface of conventional refrigeration compressor connecting bar termination contact with piston cavity internal surface completely, contact area is relatively big, and surface of friction is relatively big, causes noise in compressor operating process to increase, and the friction between piston and connecting rod makes piston easily damage, it may also be useful to lifetime.
Practical novel content
Not enough for prior art, the utility model provides a kind of refrigeration compressor piston, this piston is by increasing oil reserve and reduces weight, not only enhance the lubrication between refrigeration compressor piston and cylinder-bore, reduce the friction between refrigeration compressor piston and cylinder-bore, sealing better effects if, and the work-ing life reducing refrigeration compressor operation noise, extending piston, make refrigeration compressor service rating reduce, it is easy to low voltage starting simultaneously.
For realizing practical novel object, the utility model by the following technical solutions:
A kind of refrigeration compressor piston, comprising piston body, described piston body runs through being provided with piston pin hole, the outer wall of described piston body is provided with oil groove, the inwall of described piston body is provided with even lever attachment hole, forms arc-shaped cavity between the inwall of described even lever attachment hole both sides and piston body.
It is preferably, described oil groove width 0.3-0.6cm, described oil groove height 0.1-0.3cm.
Being preferably, described oil groove width 0.5cm, described oil groove height 0.2cm, compared with the oil groove of conventional compressor, compressor oil groove oil reserve is bigger than ever for described oil groove, is more conducive to the lubrication in machine running process, and sealing effect is better.
Being preferably, be provided with oil leak hole in described oil groove, described oil leak hole is through described oil groove, and too much lubricating oil can be leaked away by described oil leak hole, cuts the waste.
Being preferably, described oil groove cross section is trapezoidal, can store more lubricating oil while ensureing piston structure stability, and oilness and sealing effect are more obvious.
Being preferably, described piston body is provided with pilot hole, and described pilot hole is parallel with the central shaft of described piston body, and location more accurately, is conducive to closely cooperating of connecting rod and piston.
The beneficial effects of the utility model are: a kind of refrigeration compressor piston that the utility model provides, this piston is by increasing oil reserve and reduces weight, not only enhance the lubrication between refrigeration compressor piston and cylinder-bore, reduce the friction between refrigeration compressor piston and cylinder-bore, sealing better effects if, and the work-ing life reducing refrigeration compressor operation noise, extending piston, make refrigeration compressor service rating reduce, it is easy to low voltage starting simultaneously.
