Abstract
The invention discloses a connecting rod for a refrigeration compressor. The connecting rod comprises a connecting rod body, a large-head bushing, a large-head fixing part, a small-head bushing and a small-head fixing part; the connecting rod is made of high-rigidity metal materials such as aluminum alloy materials and powder metallurgical materials, a large mounting head and a small mounting head are respectively arranged at two ends of the connecting rod body, and the large-head bushing is arranged in a mounting hole of the large mounting head and is fixed by the aid of the large-head fixing part; the small-head bushing is arranged in a mounting hole of the small mounting head and is fixed by the aid of the small-head fixing part; and both the large-head bushing and the small-head bushing are made of nonmetal materials with excellent lubrication performance and abrasion resistance. The connecting rod has the advantages that the requirement of the refrigeration compressor on the rigidity during running can be met, requirements of the refrigeration compressor on aspects of lubrication, abrasion resistance and the like during running also can be effectively met, problems of poor lubrication, severe abrasion and the like in a running procedure of an existing small efficient refrigeration compressor are effectively solved, and development requirements of the refrigeration compressor technology on miniaturization and high efficiency are met.
Description
Technical field
The present invention 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 by this invention 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, refrigeration compressor of the present invention 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 present invention 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.
