Abstract

The invention discloses a helical gear oil pump suitable for automobile steering systems. The helical gear oil pump comprises a pump body, a bearing pedestal, a helical gear assembly, an oil inlet, an oil outlet, a front cover, a rear cover and sealing lining rings, wherein the bearing pedestal is fixed in the pump body; the helical gear assembly is fixed on the bearing pedestal; an oil inlet cavity and an oil outlet cavity are arranged at two sides of the pump body; the oil inlet is located on the front cover; the oil outlet is located on the rear cover; and the sealing lining rings are respectively fixed between the front cover and the pump body as well as between the rear cover and the pump body. The helical gear oil pump suitable for automobile steering systems is good in meshing property, stable in transmission, low in noise and large in contact ratio. According to the helical gear oil pump suitable for automobile steering systems, the load of each pair of gears is reduced, the bearing capacity of the gears is improved and the non-undercut minimum teeth number is less.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a gear oil pump. Background technique [0002] The steering pump is the power source of the automobile power steering system, and its performance directly affects the operation of the automobile steering system. The steering pump is driven by the car engine to rotate, and the pump outputs pressure oil to supply the car steering system, so that the car can produce oil pressure boosting effect when turning, reducing the labor intensity of the driver. However, the current external gear pump has problems with pulsation and noise, and the transmission is unstable and the bearing capacity is poor. Contents of the invention [0003] The object of the present invention is to provide a helical gear oil pump suitable for automobile steering system. [0004] According to one aspect of the present invention, there is provided a helical gear oil pump suitable for automobile steering system, includi...
