Energy-saving gear oil pump

Abstract

The invention discloses an energy-saving gear oil pump, which comprises a pump body, a driving gear shaft, a driven gear shaft, a driving gear and a driven gear, wherein the driving gear and the driven gear are arranged on the driving gear shaft and the driven gear shaft in the pump body respectively; a framework oil seal is arranged between the pump body and the driving gear shaft; a gland which is used for fixing the framework oil seal is arranged on the pump body; an end cover is arranged on the end part of the pump body; a sealing ring is arranged between the end cover and the pump body; and a sealing ring is arranged between the gland and the pump body. By adopting the structure, the framework oil seal replaces the conventional oil-immersed packing, so that the sealing property of the pump is improved greatly and the oil leakage phenomenon is avoided; therefore, the fault rate of equipment is reduced greatly, and the equipment runs safely and reliably.

Description

technical field [0001] The invention relates to an oil pump, in particular to an energy-saving gear oil pump. Background technique [0002] At present, the gearbox configured on the loader is a two-in, one-out gearbox with a twin-turbine torque converter. The gear pump used for hydraulic reversing and oil supply is a split low-pressure gear pump. This gear pump has a simple structure and low manufacturing cost. Low, but the failure rate is high. The failure phenomenon is mainly manifested as oil leakage at the joint surface, large internal leakage and easy damage after the pump has been used for a period of time. Contents of the invention [0003] In order to overcome the above disadvantages, the purpose of the present invention is to provide an energy-saving gear oil pump that prevents oil leakage and has safe and reliable performance. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] The energy-s...
