Steel belt driving mechanism

The invention relates to a steel belt driving mechanism. The steel belt driving mechanism is characterized in that a bearing is placed in a bearing hole of a load connecting seat; a rotating shaft is arranged in the load connecting seat and fixed by using a block nut; a motor is fixed on the load connecting seat; a coupler is arranged on the shaft end of a drive shaft; the motor is fixedly connected with a motor base; a roller bearing follower is arranged in a pressing block, a pin is inserted into the roller bearing follower, and a clamp spring is clamped into a clamp spring groove positioned on the pin; steel belt connecting seats are arranged in a fixed seat; a steel belt penetrates through the load connecting seat and is fixed with the steel belt connecting seats positioned on two ends; and the pressing block is matched with the load connecting seat, and the load connecting seat is connected with a load. The invention can realize the motion transmission at a longer distance, is suitable for overspeed starting due to good rigidity and great low flexibility of the steel belt and suitable for various harsh environments due to excellent heat resistance and corrosion resistance, can not generate the inertial oscillation of a similar gear and a synchronous belt and has high positioning accuracy during starting and stopping.
