Small-diameter oil seal clamp rotating main shaft driving mechanism

The invention relates to an oil seal testing device, in particular to a small-diameter oil seal clamp rotating main shaft driving mechanism. The device is characterized by comprising a main shaft support and a motor support. A bearing seat is arranged on the main shaft support, a main shaft core shaft is arranged in the bearing seat, the main shaft core shaft is in running fit with the bearing seat, and one end of the main shaft core shaft is connected with a main shaft friction wheel and a product grinding head. The motor support is connected with a servo motor through a lifting adjusting mechanism, and the output end of the servo motor is connected with a motor friction wheel. And the motor friction wheel and the main shaft friction wheel are positioned in the same vertical plane and are arranged up and down. By adopting the rotating main shaft driving mechanism, not only can the mounting space be saved, but also the energy consumption can be reduced, a plurality of main shafts can be simultaneously driven
