Abstract

The invention relates to a hydraulic pressure gear pump. It is used to improve the working press and length of life of the hydraulic pressure but need not to change the structure of the original pump body. It includes drive gear which is fasten by two drive gear axle bearing and driven gear which is fasten by two driven gear axle bearing, the particular lie on the external diameter of the driven gear must be greater than the drive gear's. The advantages are simple processing, high operation pressure and long service life.

Description

(1) Technical field [0001] The invention relates to a hydraulic gear pump, in particular to a hydraulic gear pump with different bearing structures. (2) Background technology [0002] The resultant force of the hydraulic radial force and meshing force on the main and driven gears inside the hydraulic gear pump is not equal. , The bearing of the driven gear wears faster and is damaged first. To be precise: the life of the gear pump is determined by the life of the bearings at both ends of the driven gear. The existing technology adopts a completely symmetrical structural design of the driving and driven gears, which cannot enhance the bearing capacity of the driven gears, the rated pressure of the gear pump cannot be improved, and the service life cannot be extended. (3) Contents of the invention [0003] In order to overcome the deficiencies of the above technologies, the present invention provides a gear pump with a different structural scheme for the supporting bearing...
