Hydraulic swing motor’s dynamic seal friction heat is a direct factor leading to motor’s temperature rise. To study the key factors in motor’s dynamic seal friction heat, therefore, reducing motor’s temperature rise, the contact stress model and friction model were established. Based on the swing motor of a three-axis turntable system, the relationship between three key factors was analyzed. Motor’s friction heat characteristics in two conditions were simulated, and simulation results show that with the increase of three factors, the friction heat increases obviously. Further experimental research validated the theoretical analysis and indicated that friction heat can be significantly reduced when reducing combined gasket’s compression ratio, motor’s working pressure and spindle’s speed appropriately. Furthermore, improving the machining precision of motor’s seal structure and combined seal’s installation precision also work.
