Abstract
The utility model discloses a compound gear oil pump, comprising a shell, a base, a spline, a bolt, an oil inlet and a flange, wherein the shell is made of a high-strength aluminum alloy material and the spline is arranged at the top of the shell and is located at the position of a middle axis; the base is arranged at the bottom of the shell and the base is provided with the bolt; the flange is arranged below the spline and is a rhombus flange; and the oil inlet is arranged on the shell. The compound gear oil pump has a simple structure and a selected high-quality steel product can prolong the service life; meanwhile, the compound gear oil pump has the advantages of small noise, high volume efficiency, strong shock resistance and the like in actual use through a more optimized design; and therefore, the compound gear oil pump can be widely applied in the actual application.
Description
Technical field
The utility model belongs to field of mechanical technique, in particular a kind of compound gear oil pump.
Background technique
At present; In the composite gear oil pump structure, there are a gear oil pump and a monostable diverter valve to combine, for hydraulic system provides working connection oil stream and another stable oil stream; Can be widely used in engineering machinery such as fork truck, loading vehicle, excavator, hoist, road roller; Equipment in the past in use because shortcomings such as noise is excessive, shock resistance is little, working life is short appear in the cause of design and installation.
The model utility content
The purpose of the utility model promptly produces thus, proposes a kind of compound gear oil pump, makes it in use have better adaptability.
For realizing above-mentioned purpose, the utility model realizes that through following technological scheme a kind of compound gear oil pump comprises housing, base, spline, bolt, filler opening and flange; Said housing adopts high-strength aluminum alloy material, thereby improves the working life of himself, and the top of said housing is provided with spline; And in the medial axis position, the bottom of said housing is provided with base, and said base is provided with bolt; Said flange is located at the spline below, and is the rhombus flange, and said filler opening is located on the housing.
The beneficial effect of the utility model: this composite gear oil pump structure is simple; The high-quality steel of choosing can prolong its working life; The design of more optimizing simultaneously; Make it have advantages such as noise is little, volumetric efficiency is high, shock resistance is strong in actual use, make it in practical application, can obtain promoting more widely.
