Abstract

An automatic centering piston connecting rod assembly used for a refrigeration compressor comprises a connecting rod and a piston skirt body. One end of the connecting rod is connected with the piston skirt body, and the other end of the connecting rod is connected with a crankshaft. A sphere base of which the bottom end abuts against the upper wall of the piston skirt body is installed in the piston skirt body. The sphere base comprises a sphere base body and a positioning ring integrated with the sphere base body. The outer diameter of the positioning ring is 0.05-0.1 mm smaller than the inner diameter of the piston skirt body. A sphere is installed above the sphere base body. The middle of the piston skirt body is provided with a clamping opening. A buckle plate inwards and downwards extends out of the position, located on the upper wall of the clamping opening, of the piston skirt body. A sphere upper cover is connected between the sphere and the buckle plate in a clamped mode. The wall sticking surface of the sphere base body and the sphere is provided with an oil groove. The connecting rod is provided with a vertical oil hole. The sphere is riveted to the connecting rod. The automatic centering piston connecting rod assembly used for the refrigeration compressor is convenient to install and maintain, good in lubrication effect and long in service life.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a piston connecting rod assembly. Background technique [0002] Whether it is a refrigerator or a freezer and other refrigeration equipment, their "heart" is a fully enclosed piston compressor. It is the piston in the "heart" that drives the flow of refrigerant. The piston is driven by the crankshaft, and the transmission of force through the connecting rod drives the piston to make a reciprocating linear motion in the cylinder. Because the connecting rod is in the compound motion of swinging left and right when it works, and the piston is in linear motion. In order to eliminate the interference to the piston caused by the external force in the non-linear motion direction caused by the swing of the connecting rod, the existing connection between the piston and the connecting rod is mainly connected by a ball. Therefore, how to better connect the sphere and the piston is the key. In...
