Description
Technical field
A kind of gear pump is the utility model is related to, specifically a kind of dumper gear oil pump, belongs to gear pump neck
Domain.
Background technology
Gear pump is to convey liquid by the swept volume change and movement that are formed between pumping cylinder and meshing gear or make
Supercharging drum pump.Two closing spaces are formed by two gears, the pump housing and front and rear covers, when pinion rotation, are out of gear
The volume in the space of side becomes big from small, forms vacuum, draws liquid into, the volume in the space of gear engagement side from diminishing greatly, and
Liquid is squeezed into pipeline.Suction chamber and discharge chamber are separated by the path of contact of two gears.The outlet of gear pump
Pressure depend entirely on the size of resistance at pump discharge.The anti-twist dynamics of bearing of conventional tooth wheel pump is small, low intensity, antipollution
Poor performance.
The content of the invention
The purpose of this utility model is, devises a kind of gear pump, and bearing intensity is high, and anti-twist deformation, torque resistant is big,
Antifouling property is good, reduces use cost, extends service life.
The technical solution of the utility model is:
Gear pump, including the pump housing, is provided with bearing in the pump housing, for reduce the coefficient of friction in power transmission process with
The fixation and support of gear shaft center are kept, one end of the bearing is connected with gear drive, and the both sides of the gear are set
There is side plate, for eliminating pocketed oil phenomenon, reduce gear pump noise;The axial gap of gear pump is adjusted, internal leakage is reduced, improves it
Volumetric efficiency;The other end of the bearing is connected with main wheel transmission, for gear in the motion process for rotating and engaging, makes pump
Complete the action of oil suction and oil extraction;The first oil sealing and the second oil sealing are provided between the pump housing and the bearing, for dust-proof and
The oil liquid leakage in pump chamber is prevented, being provided with hole at first oil sealing keeps off, for fixing the axial movement of oil sealing.
Wherein, the bearing is integrated shaft type needle bearing, a diameter of 36 millimeters.
Further, the side of the pump housing is provided with pump cover, forms the sealing shell of gear pump.
The utility model has the advantage of:Bearing intensity is high, and anti-twist deformation, torque resistant is big, and antifouling property is good, drop
Low use cost, extends service life.
The utility model is described in further detail with reference to the accompanying drawings and examples.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment;
In figure:The oil sealings of 1- first, the oil sealings of 2- second, 3- bearings, 4- side plates, 5- gears, 6- main wheels, 7- pump covers, the 8- pump housings,
9- holes are kept off.
Embodiment
Preferred embodiment of the present utility model is illustrated below, it will be appreciated that preferred embodiment described herein
The utility model is merely to illustrate and explained, is not used to limit the utility model.
Embodiment 1
As shown in figure 1, a kind of gear pump, including the pump housing 8, the pump housing 8 is interior to be provided with bearing 3, for reducing power transmission
During coefficient of friction and keep the fixation and support of gear shaft center, one end and the transmission phase of gear 5 of the bearing 3
Even, the both sides of the gear 5 are provided with side plate 4, for eliminating pocketed oil phenomenon, reduce gear pump noise;Adjust the axial direction of gear pump
Gap, internal leakage is reduced, improves its volumetric efficiency;The other end of the bearing 3 is connected with the transmission of main wheel 6, is being revolved for gear
Turn and the motion process of engagement in, pump is completed the action of oil suction and oil extraction;The is provided between the pump housing 8 and the bearing 3
One oil sealing 1 and the second oil sealing 2, for dust-proof and prevent the oil liquid leakage in pump chamber, hole gear 9 is provided with first oil sealing 1, is used
In the axial movement of fixed oil sealing;Wherein, the bearing is integrated shaft type needle bearing, a diameter of 36 millimeters.
The side of the pump housing 8 is provided with pump cover 7, forms the sealing shell of gear pump.
