【摘要】 针对摩擦式无级变速器摩擦生热和温度场的研究，以自行设计的新型锥齿轮-滚轮平盘式无级变速器为例，对传动过程中的滑移率、功率损失和摩擦效率进行理论研究，并用ANSYS软件对滚轮平盘摩擦生热温度场进行仿真分析。结果表明：随着转速的提高滚轮和平盘的温度上升，随着压紧力的增大，摩擦功率损失提高，摩擦效率降低；压紧力的提高，滑动速度会随之增大，产生更多摩擦热，同时也会增大接触面积，摩擦发热的面积更大，因此对温升影响更明显；新型锥齿轮滚轮-平盘式无级变速器具有较高的摩擦效率，其摩擦升温也较小。更多还原

【Abstract】 Aiming at the research of friction heat generation and temperature field of friction type CVT,taking the self-designed new type bevel gear-roller flat plate CVT as an example, the slip rate, power loss and friction efficiency in the transmission process were theoretically studied, and the temperature field of friction heat generation of roller flat plate was simulated and analyzed with ANSYS software.The results show that the friction power loss increases and the friction efficiency decreases with the increase of the rotating speed and the temperature of the roller and the flat plate.With the increase of the compression force, the sliding speed will increase so as to generate more friction heat.At the same time, the contact area will also increase, and the friction heat area will be larger, so the impact on the temperature rise will be more obvious.The new type of bevel gear roller-flat-disk CVT has high friction efficiency and low friction temperature rise.更多还原
