What special requirements do vacuum, high and low temperature, radiation and other environments have for motors and motion mechanisms?
First, the effect of vacuum, high and low temperature, radiation on the mechanical properties of the motor or moving mechanism
1, high temperature heat dissipation: there is no air convection in the vacuum environment, there is no good heat conduction mechanism, only a small amount of radiation heat dissipation, motor or motion mechanism working due to poor heat dissipation conditions produce extremely high temperature. For example, the motor temperature will reach more than 300 degrees, and the temperature resistance level of the ordinary stepper motor material is generally only 130 degrees.
2, high and low temperature deformation: in extreme high and low temperature environment, such as below 0 ° C, or higher than +50 ° C, the ordinary motor or moving mechanism can not work normally, need to do high and low temperature deformation analysis and special design of the motor and moving mechanism, precision assembly to ensure the smooth and stable work of the moving mechanism, to ensure the operation of the position accuracy.
3, high and low temperature environment material failure: ordinary materials are easy to become brittle at low temperature, easy to become soft at high temperature, and can not work normally in high and low temperature environment.
4, radiation decomposition: the use of ordinary materials of the moving platform in the radiation environment, the structural components will be decomposed, especially the use of ordinary materials will be decomposed to short circuit, operation stuck and other phenomena.
5, vacuum cold welding: in a vacuum environment, if the material in contact with each other is not specially treated, it will be bonded together because of the intermolecular force, which will have a great impact on the moving mechanism.
Second, the influence of vacuum, high and low temperature environment on grease
1. In the vacuum environment, the grease used by ordinary motors or motion mechanisms will volatilize and pollute the vacuum environment. For precision equipment such as optical equipment and mass spectrometer working in high vacuum environment, it is necessary to absolutely avoid pollution caused by volatilization of grease.
2, the grease used in ordinary products will solidified at low temperatures and cause the mechanism to jam, and the lubrication effect will fail at high temperatures.
3. Vacuum discharge
Some components will discharge in vacuum, and corona discharge is more likely to occur in high vacuum environment. Special materials are needed to avoid vacuum discharge.
How do Kingsley's product design and manufacturing processes ensure that products are suitable for these special environments?
For vacuum, high temperature, low temperature, radiation environment, our stepper motor, servo motor, linear motion platform, reducer, electric cylinder are using special materials, structural design and lubrication technology to ensure that the product can work properly in these special environments.
