Abstract
The utility model relates to a connecting rod structure in a refrigeration compressor. The connecting rod structure comprises a connecting rod body, wherein the two ends of the connecting rod body are a large connecting rod head and a small connecting rod head; the small connecting rod head is provided with a piston pin connecting hole; the large connecting rod head is connected with a crank pin connecting hole; the small connecting rod head and the large connecting rod head are communicated by a through hole; and an oil groove is arranged on the hole edge of the piston pin connecting hole. The connecting rod structure has the advantages that by the arrangement of the oil groove, not only is the lubricating action increased, but also the contact area of a connecting rod and a piston pin is reduced, and the friction force is reduced.
Description
Technical field
The utility model relates to a kind of connecting rod of compressor.
Background technique
Connecting rod small end in the refrigeration compressor and the matching gap of wrist pin are generally all very little, if move under more abominable operating mode, are easy to sting pin not with regard to causing occurring oil lubrication between the two, cause the quality problems of compressor.But can not be because of this former thereby the matching gap between connecting rod small end and the wrist pin amplified, because if the gap too large words will make and not become lubricant film between the two, can produce above-mentioned problem equally.Therefore guaranteeing under the matching gap suitable between connecting rod small end and the wrist pin that an amount of increase lubricants capacity is crucial.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provides a kind of bar linkage structure that can increase lubricants capacity between connecting rod small end and the wrist pin.
The technical scheme in the invention for solving the technical problem is:
Bar linkage structure in a kind of refrigeration compressor, comprise con-rod only, the two ends of described con-rod only are connnecting rod big end and connecting rod small end, described connecting rod small end arranges the wrist pin attachment hole, described connnecting rod big end connecting crank pin attachment hole, between connecting rod small end and connnecting rod big end, be communicated with by through hole, described wrist pin attachment hole hole along on be provided with oil groove.
As preferably, oil groove is offered according to the axial direction of wrist pin attachment hole, and described oil groove is communicated with oil through.
The utility model has been driven the bar oil groove in connecting rod small end, oil groove is communicated with oil through, therefore stores in oil that compressor is drunk up by bent axle in the running can flow to by oil through oil groove in the connecting rod small end.This oil groove has two benefits, and the one, can reduce the area of contact of connecting rod small end and wrist pin, the power of reducing friction is conducive to the reduction of power.The 2nd, can guarantee to have between connecting rod small end and the wrist pin sufficient refrigeration oil that lubrication is provided, prevent from stinging pin.
The beneficial effects of the utility model are: the utility model has not only increased lubrication by the setting of oil groove, and has reduced the area of contact of connecting rod and wrist pin, has reduced frictional force.
Description of drawings
Fig. 1 is sectional structure schematic representation of the present utility model.
Fig. 2 is main TV structure schematic representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, 2, bar linkage structure in a kind of refrigeration compressor, comprise con-rod only 1, the two ends of con-rod only 1 are connnecting rod big end and connecting rod small end, connecting rod small end arranges wrist pin attachment hole 3, connnecting rod big end connecting crank pin attachment hole 5 is communicated with by oil through 2 between connecting rod small end and connnecting rod big end, wrist pin attachment hole hole along on be provided with oil groove 4.Oil groove 4 is offered according to the axial direction of wrist pin attachment hole, and oil groove is communicated with oil through 2.
The utility model has been driven bar oil groove 4 in connecting rod small end, oil groove is communicated with oil through 2, therefore stores in oil that compressor is drunk up by bent axle in the running can flow to by oil through oil groove in the connecting rod small end.This oil groove has two benefits, and the one, can reduce the area of contact of connecting rod small end and wrist pin, the power of reducing friction is conducive to the reduction of power.The 2nd, can guarantee to have between connecting rod small end and the wrist pin sufficient refrigeration oil that lubrication is provided, prevent from stinging pin.
Claims (2)
