Abstract

This is a kind of connecting rod of hermetic compressor and its producing method. The connecting rod includes piston connecting part set in the piston and connected to the inside of piston in certain angular range; main body part with its one end connected to the said piston connecting part; and crank axle-connecting part that envelops the other end of the said main body part and is set at the other end of the said main body part. The producing method includes piston connecting part and main body part are produced; one side of the said piston connecting part and one end of the said main body part are combined; the other end of main body part is enveloped in the crank axle connecting part in order to make the crank axle connecting part assemble at the other end of the said main body part.

Description

technical field [0001] The present invention relates to a hermetic compressor, in particular to a connecting rod of a hermetic compressor composed of a crankshaft connecting part, a piston connecting part and a main body and a manufacturing method thereof. Background technique [0002] figure 1 It is a sectional view of the internal structure of a hermetic compressor manufactured by the prior art. As shown in the figure, the airtight container includes an upper container 1 t and a lower container 1 b. A frame 2 is arranged inside the airtight container 1 , and a stator 3 is arranged in the frame 2 . The above-mentioned frame 2 is arranged inside the airtight container 1 and supported by the spring 2s. [0003] Then, a crankshaft 5 is provided through the center of the frame 2 . The crankshaft 5 rotates together with the rotor 4 due to the mutual electromagnetic interaction between the rotor 4 and the stator 3 integrally formed therewith. The upper end of the crankshaft 5...
