Problems solved by technology

When the shaft hole of the pump body or the pump cover is relatively long, if a bush is used, the lubricating oil enters from the high-pressure oil end through the gap between the bush and the shaft, and it is difficult to fully lubricate the outer end

Abstract

The invention provides a gear type oil pump capable of rapidly lubricating linings. The oil pump comprises a pump body, a pump cover, a driving shaft, a driving gear, a driven shaft and a driven gear;the driving gear is fixedly installed in the middle of the driving shaft, the two ends of the driving shaft are rotatably installed in axle holes formed in the pump body and the pump cover respectively, and the linings are press-mounted in the axial holes of the pump body and the pump cover; the driven gear is rotatably installed in the middle of the driven shaft, one end of the driven shaft is fixedly installed on the pump body, two linings are press-mounted in the axle hole of the pump body or the pump cover, the two linings are arranged at an interval to make a first annular groove formedin the axle hole of the pump body or the pump cover, and an oblique oil hole used for communicating the first annular groove with a high pressure oil cavity is formed in the pump body or the pump cover. In this way, lubricating oil can directly enter the middle of the axle hole to rapidly lubricate the surfaces of the linings and the driving shaft, and sufficient lubricating oil can be provided for the outer side end for lubricating conveniently.

Description

technical field [0001] The invention relates to a component of an engine lubricating system, in particular to a gear type oil pump. Background technique [0002] In the existing oil pump, it is usually necessary to guide the high-pressure oil in the oil outlet area to the shaft hole of the pump body and the pump cover through the lubricating oil groove, so as to lubricate the space between the shaft hole and the rotating shaft. In addition, to avoid wear, a bushing is usually press-fitted in the shaft bore. When the shaft hole of the pump body or the pump cover is relatively long, if a bush is used, the lubricating oil enters from the high-pressure oil end through the gap between the bush and the shaft, and it is difficult to fully lubricate the outer end. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a gear type oil pump capable of quickly lubricating the bushing. [0004] In order to solve the above-mention...
