Embodiment 1

[0021] like figure 2 As shown, the present invention includes a connecting rod body 1 , a piston pin 2 , a piston 3 , an eccentric shaft 4 , a crankshaft 5 , an intermediate connecting ball 6 , a second polytetrafluoroethylene product 7 , and a circlip 8 . The intermediate connecting ball 6 is made of polytetrafluoroethylene, and the intermediate connecting ball 6 is provided with a piston pin connecting through hole adapted to the piston pin 2 . The connecting rod body 1 is connected to the piston pin 2 in a transmission through the intermediate connecting ball 6 . The second polytetrafluoroethylene part 7 is arranged between the crankshaft 5 and the connecting rod body 1. The second polytetrafluoroethylene part 7 in this embodiment is a polytetrafluoroethylene sleeve, and the corresponding end of the crankshaft 5 passes through Passing through the second polytetrafluoroethylene part 7 and provided with a circlip groove 5.1 at the penetrating part, the circlip 8 is connecte...

Embodiment 2

[0028] The difference between the second embodiment and the first embodiment is that in the second embodiment, the second polytetrafluoroethylene component 7 is a polytetrafluoroethylene coating plated on the crankshaft 5 and slidably connected to the corresponding surface of the connecting rod body 1. ; It can also be a polytetrafluoroethylene coating plated on the connecting rod body 1 and slidably connected to the corresponding surface of the crankshaft 5 .

[0029] In the above specific embodiment, the specific structural details of other parts of the crankshaft 5 except for the specific structural details of the part connected to the connecting rod 1 are all known in the art, so no illustration or text description is provided.

Abstract

A compressor connecting rod assembly comprises a connecting rod body, a piston pin, a piston, an eccentric shaft, a crankshaft and a middle connecting ball. The middle connecting ball is a polytetrafluoroethylene part, and a piston pin connecting through hole matched with the piston pin is formed in the middle connecting ball. The connecting rod body is in transmission connection with the piston pin through the middle connecting ball, and a second polytetrafluoroethylene workpiece is arranged between the crankshaft and the connecting rod body. The connecting rod body can be made of common steel, the connecting rod body is indirectly connected with the crankshaft and the piston pin through the second polytetrafluoroethylene workpiece and the middle connecting ball made of polytetrafluoroethylene, and the structure for machining lubricating oil on the connecting body can be omitted by means of the self-lubricating characteristic of polytetrafluoroethylene. And due to the adoption of the middle connecting ball, the requirement on form and location tolerance of related connection can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a spherical articulated connecting rod for a sealed reciprocating refrigerator compressor. Background technique [0002] The performance of the refrigerator compressor has a significant impact on the overall performance of the refrigerator. like figure 1 As shown, the crankshaft of the reciprocating refrigerator compressor drives the connecting rod, and the connecting rod drives the piston in the crankcase to move back and forth to achieve the compression effect. But at present the piston and the connecting system pass through a perpendicular to the figure 1 The piston pin on the horizontal plane shown is connected, and in order to prevent the wear of the connecting rod, the piston pin and the crankshaft joint, there are special requirements on the selection of connecting rod material and structure [for example, the structure requires machining on the connecting...
