Rotor fluid mechanical transfiguration mechanism

Abstract

The invention discloses a rotor fluid mechanical transfiguration mechanism which comprises a working cylinder (housing) with fluid inlets and fluid outlets, and a rotating shaft, wherein an olive-shaped stator, olive-shaped rotors and a planetary gear train transmission mechanism are equipped in the working cylinder; the olive-shaped rotors are equipped on planetary gears of the planetary gear train transmission mechanism; a centre sun gear fixed on the planetary gear train transmission mechanism is meshed with inertia gears; the inertia gears are meshed with the planetary gears; the centre vertical axes of olive-shaped cross sections of the olive-shaped rotors keep perpendicular to those of the olive-shaped cross section of the olive-shaped stator all along; beads and arc surfaces of the olive-shaped rotors, inner periphery curved surface wall of a housing chamber and the arc surfaces and beads of the olive-shaped stator are in mutual alternating contact and slide fit correspondingly; plane end surfaces on the two sides of the olive-shaped rotors and the inner side plane wall surface of the housing are mutually contacted and in dynamic seal slide fit. The transmission mechanism further reduces the pressure fluctuation and vibration, the energy loss and abrasion are relatively small, solid pollutants accumulated in the chamber can be automatically cleared, and the processing and manufacturing cost is relatively low.

Description

technical field [0001] The invention relates to a hydraulic or pneumatic power machine, especially a rotor fluid mechanical displacement mechanism.

AI Technical Summary

Problems solved by technology

The characteristics of the vane pump are: compact structure, high working pressure, small flow pulsation, stable operation, low noise, small size, light weight, long service life, long service life of bearings, good durability, high volumetric efficiency, low working pressure High, the disadvantages of the vane pump are: the oil absorption characteristics are not very good, it is also sensitive to oil pollution, the blades are easy to bite, the work reliability is poor, the structure is more complicated, the manufacturing process requirements are relatively high, the speed regulation range is small, the highest The rotation speed is low. Due to the influence of factors such as blade throwing force, oil absorption speed and wear, the rotation speed of the pump should not be too high or too small. No oil intake, or discontinuous oil absorption, and when the speed is low, the blades cannot cling to the inner surface of the stator due to insufficient centrifugal force, and cannot form a well-sealed closed volume, so that oil cannot be absorbed

[0007] The characteristics of the gear pump are: low cost, simple structure, small size, light weight, good workmanship, cheap price, strong self-priming ability, insensitive to oil pollution, large speed range, easy maintenance, reliable work, and used for low pressure The system has low requirements on the cleanliness of the working medium, radial force (with internal leakage), good self-priming performance, and large pressure pulsation; its disadvantages are serious oil trapping, large radial unbalanced force, large leakage, and high flow rate. The pulsation is large and the noise is high. Like the gear pump, the gear hydraulic motor has poor sealing and low volumetric efficiency, so the input oil pressure cannot be too high, so it cannot generate a large torque, and the speed and torque are both Pulsating due to gear meshing
