Belt drive based platform capable of continuously rotating

The invention discloses a belt drive based platform capable of continuously rotating. The platform comprises a fixed support, a servo motor, a driving synchronous wheel, a crossed roller bearing, a driven synchronous wheel, a rotating platform and a cap type electric conduction sliding ring. The servo motor is fixed to the fixed support, and an output shaft of the servo motor extends to the bottomof the fixed support. The driving synchronous wheel is located at the bottom of the fixed support and is fixedly connected with the output shaft of the servo motor. The outer ring of the crossed roller bearing is fixed to the bottom of the fixed support, and the rotating axis of the crossed roller bearing is parallel to the output shaft of the servo motor. The driven synchronous wheel is providedwith a center hole and is fixed to the bottom of the inner ring of the crossed roller bearing through a bolt, and the driven synchronous wheel and the driving synchronous wheel are in drive connection through a synchronous be
