Compressor crankshaft connecting rod oil supply mechanism and compressor

Abstract

The invention discloses a compressor crankshaft connecting rod oil supply mechanism and a compressor, and belongs to the technical field of compressors. The problems that in the prior art, oil discharge is increased when a compressor operates under the working conditions of high rotating speed and high load, and formation of a friction pair oil film is not facilitated are solved. The compressor crankshaft connecting rod oil supply mechanism comprises a machine base with an air cylinder hole and a shaft hole; a crankshaft, wherein a long shaft of the crankshaft is rotationally arranged on the shaft hole of the machine base; a connecting rod, wherein a pin shaft hole and a crankshaft hole are formed in the two ends of the connecting rod respectively, and a short shaft of the crankshaft is rotationally connected with the crankshaft hole; and a piston, wherein the piston is movably arranged in the air cylinder hole, a pin shaft is fixedly arranged on the piston, and the pin shaft is rotationally connected with the pin shaft hole. A first matching surface between the long shaft and the shaft hole is provided with a first oil duct with an oil supply inlet and an oil supply outlet. The oil discharge quantity is reduced, oil discharge atomization is improved, the oil quantity in circulating air suction is reduced, and the high-frequency refrigerating capacity of the compressor is improved.

Description

technical field [0001] The invention relates to the technical field of air compressors, in particular to a compressor crankshaft connecting rod oil supply mechanism and a compressor. Background technique [0002] The oil discharge rate and lubrication effect of the compressor can have a direct impact on the performance. In order to achieve the same refrigeration capacity as the large displacement of the small displacement compressor, it is necessary to increase the cooling capacity of the compressor at high speed by increasing the speed of the compressor. , as the speed increases, the oil displacement also increases. In order to reduce the oil discharge rate of the compressor, the existing technology mostly uses an oil retaining device installed on the connecting rod to reduce the oil discharge rate during the operation of the compressor to increase the cooling capacity of the compressor, but it is not conducive to the high performance of the broadband compressor. The forma...
