Abstract
The utility model relates to a split link for totally-enclosed refrigeration compressors. The split link is an improvement of the general integral link in the existing refrigeration compressors. The split link is characterized in that a bigger axial end hole of the link is cut into two parts, comprising a link cover and a link body which are connected integrally by screws. The connecting part of the link cover and the link body is designed with a screw mounting lug boss. The pore diameter of the link of the utility model is decreased, thus the contacting area of an eccentric shaft of a crankshaft and the link is decreased, and the frictional force is decreased. Therefore, the input power can be effectively decreased, and the COP value of the compressor can be raised.
Description
(1) technical field: the utility model relates to the component in the refrigeration compressor, is a kind of hermetically sealed compressor split type connecting rod.
(2) background technique: in the prior art, what the connecting rod that is connected with crankshaft eccentric shaft in the hermetic piston compressor generally used is the integrated type connecting rod, and its two ends size axis hole is the sealing monolithic construction; Because the special construction of crankshaft eccentric shaft, the diameter of axle at its installing connecting rods place are less than the two ends eccentric structure, therefore, the aperture of the big axis hole of existing integrated type connecting rod must just can install up greater than eccentric structure, and like this, the connecting rod aperture is big, and inevitable frictional force is just bigger.For the frictional force that reduces the integrated type connecting rod just can only reduce the thickness of integrated type connecting rod, and the thickness of connecting rod can not subtract too smallly, and when the thickness of connecting rod reduced, the intensity of connecting rod can reduce rapidly.So the axis hole of integrated type connecting rod must be big and thick, cause input power big and be difficult to lower.
(3) summary of the invention: the purpose of this utility model is that to solve in the existing compressor between the connecting rod and crankshaft eccentric shaft frictional force big, the problem that input power is big, provide a kind of easy for installation, the connecting rod axis hole is little, the hermetically sealed compressor that frictional force is little split type connecting rod.
Concrete scheme of the present utility model is: existing integrated type connecting rod is improved, particularly: with the macro-axis nose end subdivision of connecting rod is two halves, be divided into connecting rod cap and connecting rod shank, both adopt screw to connect one, and the joint outer wall design of connecting rod cap and connecting rod shank has the screw installation base.
In the utility model, described connecting rod cap is that two ladder surfaces dock with the interface of connecting rod shank, and its inboard ladder surface joint is gapped, and width is 0.3-0.8mm.When this two gap can guarantee that screw is fastening, contactless of connecting rod shaft hole inner wall, the amount of deformation of the extrusion-deformation that produces all produced on the surface of contact in the connecting rod cap and the connecting rod shank interface outside, have guaranteed the circularity and the cylindricity of connecting rod axis hole inner chamber.
For improving bearing capacity of the present utility model, can halfliner be installed at the inner side surface on connecting rod cap or the connecting rod shank.
Split type structure of the present utility model makes its connecting rod aperture reduce greatly than the integrated type connecting rod, thereby has reduced the area of contact of connecting rod and crankshaft eccentric shaft, reduces friction, and then can effectively reduce input power, improves the COP value (being approximately 3-5%) of compressor.
(4) description of drawings:
Accompanying drawing is a general structure schematic representation of the present utility model.
Among the figure: 1-connecting rod cap, 2-connecting rod shank, 3-screw, 4-boss, 5-gap, 6-halfliner.
(5) embodiment:
Referring to accompanying drawing, the utility model adopts screw 3 to be formed by connecting by connecting rod cap 1 and connecting rod shank 2.In the outer wall design of the joint of connecting rod cap 1 and connecting rod shank 2 screw installation base 4 is arranged, so that mounting screw.Connecting rod cap 1 is that two ladder surfaces dock with the interface of connecting rod shank 2 in the utility model, and its inboard ladder surface joint is gapped 5, and its width is 0.3-0.8mm.In the present embodiment, the inboard suitably attenuate of the axis hole of connecting rod cap 1 is equipped with halfliner 6, to improve the bearing capacity of connecting rod.
Claims (3)
1. hermetically sealed compressor split type connecting rod, the two ends design of connecting rod has large and small axis hole, it is characterized in that: connecting rod macro-axis nose end subdivision is two halves, be divided into connecting rod cap and connecting rod shank, both adopt screw to connect one, and the joint outer wall design of connecting rod cap and connecting rod shank has the screw installation base.
2. a kind of hermetically sealed compressor split type connecting rod according to claim 1 is characterized in that: described connecting rod cap is that two ladder surfaces dock with the interface of connecting rod shank, and its inboard ladder surface joint is gapped, and width is 0.3-0.8mm.
