A Ring Spoke Spring Compensation Gear Pump

Abstract

A ring spoke spring compensation gear pump, comprising a driving shaft, a driven shaft, a main gear, a slave gear, a ring spoke main spring, a ring spoke slave spring, an end surface compensation disc, a front outer end cover, an end cover screw, a pump body, a rear Outer end cover, there is an end surface compensation disc between the main gear and the slave gear and the front outer end cover, and the ring of the ring-spoke main spring is fixed at the corner of the main ring in the back recess of the compensation disc, and the spoke pressure of the ring-spoke main spring Lean against the inner side of the front end outer cover; the back concave of the compensation disc fixes the ring spokes from the ring of the spring from the ring angle, and the ring spokes are pressed against the inner side of the front end outer cover from the spokes of the spring. With the help of the axial rebound force produced by the spokes of the ring spoke main spring and the spokes of the ring spoke slave spring respectively pressing against the inner side of the front end outer cover, the positive plane of the end face compensation disc is in close contact with the sides of the main gear and the slave gear. One end plane forces the main gear and the other side end plane of the slave gear to be close to the inner plane of the rear outer end cover, ensuring that the gear pump is always running at high efficiency.

Description

Technical field [0001] The invention belongs to the field of mechanical engineering. The international patent classification is F04D non-variable volume pump. It relates to an energy conversion rotary displacement pump that converts mechanical energy into liquid pressure energy, in particular to a ring spoke spring compensated gear pump. Background technique [0002] Rotary positive displacement pumps have the advantages of high efficiency, but their efficiency is significantly reduced after long-term operation and wear. The main reason for the above-mentioned defects is that the end surface movable isolation between the high-pressure cavity and the low-pressure cavity fails to effectively seal. If the end-face tolerance is too small, it is easy to get stuck due to thermal expansion. If the end-face tolerance is too large, it will not be able to effectively seal, and the sealing effect will be worse after long-term operation and wear. The production line has to be stopped to repla...

AI Technical Summary

Problems solved by technology

The problem that has not been effectively solved is that after long-term high-speed operation, the inevitable wear of the end face cannot be effectively compensated.
