Abstract
The utility model discloses a gear gas pump, which is mainly composed of a pump body, a gear, a flange, etc. the gear gas pump can be in normal operation through the flange being connected with a gear transmission body. The utility model can be used for an engine with a vacuum pump; the utility model can be directly installed by utilizing an original seat hole of an original vacuum pump, any change is not needed to an original engine; the hydraulic braking of a vehicle can be conveniently modified into the pneumatic braking.
Description
The utility model relates to a kind of improvement of pump structure, particularly a kind of employing gear transmission, the Gear gas pump that flange connects.
In general large-scale haulage vehicle, as east wind EQ1061 series, what adopt is hydraulic braking, and the effect of hydraulic braking is than the weak effect of air-pressure brake, part car changes hydraulic braking into air-pressure brake, and when repacking air pump being installed needs more gear changing, a series of accessories such as gear chamber and gear chamber cover, modification difficulty is big, the cost height.
The purpose of this utility model provides that a kind of repacking is convenient when hydraulic braking changes air-pressure brake into, cost is low, the Gear gas pump of good reliability.
The purpose of this utility model is achieved in that a kind of Gear gas pump, comprise the pump housing 1, the pump housing 1 middle part is a main shaft 2, main shaft 2 front ends are provided with gear 3, gear 3 is fixed on the main shaft 2 by nut 4, be flange 5 between the gear 3 and the pump housing 1, flange 5 middle parts are provided with spill port 6, and flange 5 two ends are provided with retaining screw 7.
Gear gas pump provided by the utility model will fixedly change flange into by support with front pump and fix, and means of fixation is simplified, and fixed effect improves; Change the more stable work that gear transmission makes the pump housing into by belt transmission; Change the oil return mode into spill port by return tube,, guaranteed the proper functioning of gear by the gear chamber oil return.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
The utility model adopts following structure: a kind of Gear gas pump, comprise the pump housing 1, the pump housing 1 middle part is a main shaft 2, main shaft 2 front ends are provided with gear 3, gear 3 is fixed on the main shaft 2 by nut 4, be flange 5 between the gear 3 and the pump housing 1, flange 5 middle parts are provided with spill port 6, and flange 5 two ends are provided with retaining screw 7.
In the utility model when work,, the retaining screw 7 by flange 5 and flange 5 two ends is installed on the motor, utilizes the power driven gear 3 of motor to rotate and can make the pump housing 1 work.The spill port 6 at flange 5 middle parts makes gear 3 keep lubricated, has guaranteed the proper functioning of entire pump.
