AI Technical Summary
On the coating line, because the chain sprocket transmits power, the chain sprocket is prone to injuring people, and the power transmission node cannot be fully protected with the cover, resulting in a safety threat to the operator.
Design a torque limiter application mechanism on the coating line. The ground shaft is driven by an AC reduction motor. The ground shaft is the total power of the system. A sprocket with a torque limiter is installed on the ground shaft and at the input end of the reducer. When the sprocket chain is involved in clothing or the human body, due to the sudden increase in torque, the torque on the sprocket exceeds the set value of the torque limiter, causing slipping. The ground axis rotates but the sprocket chain does not rotate, thereby avoiding accidents that injure people.
It effectively avoids accidents involving sprocket chain injuries, improves the safety of operators, and ensures the safety of machine debugging.

Specifically, the side wall of the bracket 100 is installed with the earth shaft 110 through the bearing seat, and the side wall of the bracket 100 is installed with the gearbox. In this embodiment, the earth shaft 11 A first sprocket 111 is installed on the torque limiter 200 at the 0-axis end, a second sprocket 121 is installed at the input of the gearbox, a third sprocket 123 is installed at the output end of the gearbox, a first chain 122 is arranged between the first sprocket 111 and the second sprocket 121, a fourth sprocket 130 is arranged on the side wall of the bracket 100, a second chain 124 is arranged between the third sprocket 123 and the fourth sprocket 130, a bearing frame 141 is arranged on the side wall of the bracket 100, and a tensioning wheel 140 for tightening the second chain 124 is installed on the side wall of the bearing frame 141;
[0025] The function of the torque limiter 200 is that when the torque on the sprocket exceeds the set value of the torque limiter 200 and slippage occurs, the ground shaft 110 rotates but the sprocket chain does not rotate, thus avoiding accidents of sprocket chain injuring people.
