Heat flow change automatic balance system

Abstract

The invention discloses a heat flow variation automatic balanced system which comprises an inner ring body (1), an outer ring body (3) and a heat flow material (5), wherein the outer diameter of the inner ring body (1) is provided with a spiral gear ring (2); the inner diameter of the outer ring body (3) is provided with a spiral gear ring (4); a certain distance space is arranged between the meshing of two spiral gears; and a heat flow material (5) is arranged in the space. The heat flow variation automatic balanced system has the advantages that in order to reduce the deviation of the rotation physical center and mass center of a rotor, the temperature for heating a heat flow body deformation sleeve is lowered to reduce the deformation force and improve the centrifugal force, thereby achieving the automatic balanced state of the dynamic balance, and the eccentric state required by two-heart balance also can be maintained after the normal temperature state is recovered, thus a rotor-type rotation device can achieve the ideal dynamic balanced performance.

Description

technical field [0001] The invention relates to the technical field of mechanical shaft balance, in particular to an automatic balance system for heat flow fluctuations. Background technique [0002] The importance of the dynamic balance index to the rotating device is self-evident. It has a key impact on the life, precision, noise, stability and reliability of the rotating device. It is an index that must be confirmed and met. [0003] The dynamic balance of the rotor is affected by many factors such as final design, material, processing, temperature, speed, assembly, etc. After the final assembly, it will also be affected by unpredictable conditions such as index, stress, and deformation, which will deteriorate the dynamic balance again. [0004] Dynamic balance measurement and calibration requires a bench and equipment. According to the measured data, the mass of the appropriate part of the rotor is increased or decreased. The above-mentioned process generally requires mu...

Problems solved by technology

[0009] In fact, when the rotor in engineering is completely dynamically balanced, the comprehensive torque balance around the axis can be regarded as a gyroscope. When it is unbalanced, the side with the larger comprehensive torque of the rotor will generate centrifugal force, causing the rotor to precess. As a result, extra centrifugal pressure is generated for the supporting shaft and the bearing supporting the shaft. When it is horizontal, it is combined with the gravity of the earth to produce up and down. When it is vertical, it produces circumferential shaking. These are the accelerated wear of the bearing, the decrease of precision, the decrease of fatigue life, and the vibration and noise. , heat source, etc.
