Abstract
The utility model discloses a connecting rod for a refrigerating compressor. The connecting rod for the refrigerating compressor comprises a connecting rod body, a large head lining, a large head fixing part, a small head lining and a small head fixing part; the connecting rod body is made of strong-rigidity metal materials such as aluminum alloy and powder metallurgy, two ends of the connecting rod body are respectively provided with a large installation head and a small installation head, and the large head lining which is arranged in an installation hole of the large installation head is fixed through the large head fixing part; the small head lining which is arranged in an installation hole of the small installation head is fixed through the small head fixing part; the large head lining and the small head lining are made of non-metallic materials which have good lubricating and wear resistant performance. The connecting rod for the refrigerating compressor has the advantages of satisfying refrigerating compressor operational requirements for stiffness, well satisfying refrigerating compressor operational requirements for lubricating, wear resistant and the like, effectively solving the problems of poor lubrication, badly abrasion and the like caused in operation process of a small-sized refrigerating compressor and satisfying refrigerating compressor technological development requirements for miniaturization and high efficiency.
Description
Technical field
The utility model relates to refrigeration technology field, specifically a kind of bar linkage structure that is applied to refrigeration compressor.
Background technique
The general reciprocating type crank/linkage mechanism that adopts as shown in Figure 1 of existing refrigeration compressor comprises bent axle 1, connecting rod 2, piston 3, wrist pin 4 and cylinder-bore 5.Piston 3 is installed in the cylinder-bore 5, is connected with bent axle 1 with connecting rod 2 by wrist pin 4. and during compressor operating, bent axle 1 rotates, and it is reciprocating in cylinder-bore 5 to drive piston 3 by connecting rod 2.In recent years, along with the refrigerant compression machine technology develops to miniaturization and high efficiency direction, to the demands for higher performance such as lubricated, wear-resisting of each kinematic pair.And the main parts size of connecting rod to be refrigeration compressor bear load, basic metallic material such as aluminum alloy, the powder metallurgy etc. of adopting are made at present.Thereby in the refrigeration compressor running, phenomenons such as insufficient lubrication, serious wear appear through regular meeting, hindered the technological progress of refrigeration compressor aspect miniaturization and high efficiency.
Summary of the invention
Technical problem to be solved in the utility model is to propose a kind of refrigeration compressor connecting rod that composite material is made of using, and can effectively solve problems such as the insufficient lubrication that produces in the small-sized efficient refrigeration compressor running, serious wear.
For solving the problems of the technologies described above, the utility model refrigeration compressor comprises connecting rod shank, major part lining, major part fixed block, small end bushing and microcephaly's fixed block with connecting rod, described connecting rod shank adopts metallic material to make, its two ends are respectively equipped with big installation head and little installation head, described major part lining is located in the mounting hole of described big installation head, fixes by described major part fixed block; Described small end bushing is located in the mounting hole of described little installation head, fixes by described microcephaly's fixed block; Described major part lining and small end bushing all adopt nonmetallic material to make.
Above-mentioned refrigeration compressor connecting rod, be respectively equipped with major part fixed block mounting groove and microcephaly's fixed block mounting groove on the outer wall of described major part lining and small end bushing, described major part fixed block and microcephaly's fixed block are located at respectively in described major part fixed block mounting groove and the microcephaly's fixed block mounting groove.
The utility model can satisfy the required rigidity requirement of refrigeration compressor operation owing to adopted technique scheme, connecting rod shank can adopt the stronger metallic material of rigidity such as aluminum alloy, powder metallurgy to make to guarantee connecting rod.Nonmetallic material lubricated, that wear-resisting property is good are made and major part lining and small end bushing can adopt, can satisfy the requirement of aspects such as refrigeration compressor when operation be lubricated, wear-resisting better, so just can solve problems such as the insufficient lubrication that produces in the small-sized efficient refrigeration compressor running, serious wear effectively, satisfy the needs that the refrigerant compression machine technology develops to miniaturization and high efficiency direction.
