Problems solved by technology
Adopting the ordinary opposed double-cylinder structure can effectively increase the cooling capacity of the refrigeration compressor, but due to the difficulty in the structural arrangement of the connecting rod and the crankshaft, the overall height and weight of the opposed double-cylinder refrigeration compressor also increase accordingly, and the cooling The increase in weight ratio is limited, and the application range is very small

Embodiment Construction
[0018] Such as figure 2 As shown, the connecting rod mounting structure applied to the opposed double-cylinder refrigeration compressor of the present invention includes a crankcase 1a, a crankshaft 2, a right connecting rod 3a, a left connecting rod 3b, a right piston pin 4a, a left piston pin 4b, and a right piston 5a , left piston 5b, right valve group 7a, left valve group 7b, motor 8, support spring 9 and housing 10. Crankcase 1a is provided with right cylinder 6a and left cylinder 6b, right piston 5a is installed in right cylinder 6a, left piston 5b is installed in left cylinder 6b, left connecting rod 3b and right connecting rod 3a pass through left piston pin 4b, right Piston pin 4a is connected with left piston 5b and right piston 5a respectively. When the compressor is running, the motor 8 drives the crankshaft 2 to rotate, drives the right piston 5a to reciprocate through the right connecting rod 3a, and drives the left piston 5b to reciprocate through the left con...

The invention discloses a connecting rod installation structure applied to an opposed double-cylinder refrigeration compressor, which comprises a crankcase, a crankshaft, a right connecting rod, a left connecting rod, a right piston pin, a left piston pin, a right piston, a left piston, a right valve group, a left valve group, a motor, a support spring and a shell body; a right cylinder and a left cylinder are arranged on the crankcase; the right piston and the left piston are respectively arranged in the right cylinder and the left cylinder; the left connecting rod and the right connecting rod are respectively connected with the left piston and the right piston; a middle shaft sleeve is arranged on the right connecting rod; the left connecting rod is provided with an upper shaft sleeve, a groove and a lower shaft sleeve; and the middle shaft sleeve, the upper shaft sleeve and the lower shaft sleeve are respectively guided into the crankshaft. The installation structure can greatly reduce the reciprocating inertial force when the pistons, the connecting rods, the piston pins and other parts move, realize the balance of a moving system with a miniature mechanism structure, and reduce the overall height and the overall weight of the compressor, so that the refrigerating output and the cold-to-weight ratio of the compressor are improved.
Description
[0001] technical field [0002] The invention relates to a connecting rod installation structure applied to an opposed double-cylinder refrigeration compressor. [0003] Background technique [0004] Such as figure 1 As shown, the existing refrigeration compressor generally adopts a single cylinder mechanism, including crankcase 1, crankshaft 2, connecting rod 3, piston pin 4, piston 5, valve group 7, motor 8, support spring 9, housing 10 and other parts, The crankcase 1 is provided with a cylinder 6, and the piston 5 is installed in the cylinder 6 of the crankcase 1. When the compressor is running, the motor 8 drives the crankshaft 2 to rotate, and the connecting rod 3 drives the piston 5 to reciprocate. The ratio of the cooling capacity of the compressor to the weight of the whole machine is referred to as the cooling-to-weight ratio, which is an important indicator for evaluating the miniaturization level of the refrigeration compressor. With the continuous improv...
