Abstract
The utility model provides an oil circuit structure of air compressor crankcase belongs to air compressor technical field. It has solved traditional lubricating oil circuit design possible existence lubricating oil distribution uneven, lubrication effect is not good and so on problem. The oil circuit structure of this air compressor crankcase, including crankcase body and the cavity that opens inside crankcase body, is located the opening for and the crankcase cover intercommunication with cavity top end surface, the port that has with cavity connection is located on one end of crankcase body, the boss corresponding with port is seted up on the other end of crankcase body, and the boss is hollow structure, and the port is connected with the boss and cavity, and the boss is seted up in the installation groove, is located the ball bearing one of installation groove inside setting, is seted up in the recess of one side of installation groove, and the ball bearing two and the oil seal ring of hollow structure are seted up in the recess. The utility model has improved lubrication effect and reduced the advantage of friction.
