Timing belts are used in automatic doors and half-height shielded doors.
Half-height screen doors are platform equipment for railway transportation.
The purpose of assembly is to prevent passengers from accidentally falling into the rails and being injured. The gates are centrally controlled by a computer, and the internal transmission device is combined with the motor. thereby achieving the effect of automatically opening and closing the door inward or outward at the platform. The timing belt and the timing pulley are engaged, and the transmission is smooth and not stuck. The automatic door belt is used to control the switch of the automatic door. The inner circumference of the automatic door belt is made into a toothed shape and meshes with the toothed pulley.
Since the strong layer deforms little after being loaded, it can keep the toothed belt circumference unchanged. There is no relative slippage between the belt and the pulley, ensuring a constant transmission ratio.
