Development of Water-cooling Transmission Device for Magnetorheological Fluid

Magnetorheological (MR) transmission that uses the rheological effect of MR fluid to transfer power is a new form of power transfer, which can achieve stepless control of torque and speed by adjusting the intensity of external magnetic field. In the study, a water-cooling heat dissipation scheme was proposed. The temperature simulation of MR transmission under natural heat dissipation and water-cooling heat dissipation was carried out by using the finite element method. Based on the design of the water-cooling MR transmission device (MRTD), the torque transmission and temperature rise characteristics of the MRTD were studied, and the influence of the heat dissipation mode on the transmission torque of the device was explored. Results show that the water-cooling method can control the temperature rise of the MRTD effectively.
