Abstract

The utility model discloses a low-noise gear oil pump. The low-noise gear oil pump comprises a shell, a bottom cover, a bearing, an oil inlet, bolts and a flange, wherein the shell is made of a high-strength aluminium alloy material; the bearing is arranged on the \middle axis of the shell; the bottom cover is arranged at the bottom of the shell and is provided with the bolts; the flange is arranged on the bearing and is diamond-shaped; and the oil inlet is arranged on one side of the shell. The low-noise gear oil pump disclosed by the utility model is unique in concept and simple in structure; in the actual use of the oil pump, the service life of the oil pump can be prolonged by selected high-quality steel; and simultaneously, due to the optimized design, the oil pump has the advantages that the size is reduced, the volume efficiency is improved, the vibration resistance is enhanced, and the noise is reduced.

Description

A kind of low noise gear oil pump
Technical field
The utility model belongs to field of mechanical technique, in particular a kind of low noise gear oil pump.
Background technique
At present; It is that the swept volume that forms between pumping cylinder and engaging gear changes and moves the rotary pump of carrying liquid or making it supercharging that gear oil pump mainly relies on; It has been widely used in electronic haulage equipment; But volume is excessive, noise is excessive because some oil pumps exist, and brings a lot of inconvenience for operator's use.
The model utility content
The purpose of the utility model promptly produces thus, proposes a kind of low noise gear oil pump, makes its noise in actual use low.
For realizing above-mentioned purpose, the utility model is realized through following technological scheme, a kind of low noise gear oil pump; Comprise housing, bottom, bearing, filler opening, bolt and flange, said housing adopts high-strength aluminum alloy material, and the medial axis position of said housing is provided with bearing; The bottom of said housing is provided with bottom, and said bottom is provided with bolt, and said flange is located on the bearing; And be the rhombus flange, said filler opening is located at a side of housing.
The beneficial effect of the utility model: the design of this gear oil pump is unique, and is simple in structure, in actual use; The high-quality steel of choosing can prolong its working life, and the design of more optimizing has simultaneously reduced its volume; Improved its volumetric efficiency, it is strong to have strengthened its shock resistance, has reduced its noise.
