Description

technical field [0001] The invention relates to the technical field of transmission part sealing, in particular to a dynamic sealing transmission device. Background technique [0002] When performing high and low pressure environmental experiments on the load characteristics of mechanical rotating power output equipment, it is necessary to use an environmental simulation box to simulate a very high pressure test environment. However, the equipment used to apply torque load to the equipment under test must be placed in a conventional environment due to its own performance and other reasons, that is, the mechanical rotating power output equipment and load equipment to be tested must be placed in the environmental simulation box cabin and outside the cabin, respectively. . In this case, there is a pressure difference between the equipment under test and the environment where the load is located, and the transmission parts need to be sealed. [0003] Such as figure 1 As shown...

AI Technical Summary

Problems solved by technology

However, this way of using permanent magnets to transmit torque is related to the strength of the magnetic field and the phase difference. There will be asynchronous rotation between the input and output shafts, and there will also be a phase difference during forward and reverse rotation. It is not suitable for applications that require measurement results. higher environmental test

In addition, the magnetic fields at the input and output shaft ends cannot be adjusted, and there are extreme values ​​of the transmitted torque, which makes it inconvenient to adjust the maximum transmitted torque
