Design Features
- Internally mounted, singe face, unbalanced structure, single spring and driven by the abreast would ring on both ends of the spring, driven by brace ear and claw transmission
- The spring rotating direction is determined by the direction of the shaft rotation
1. Clockwise rotation looking the shaft from "A" side, the spring rotating direction is right-hand
2. Anticlockwise rotation looking the shaft from "A" side, the spring rotating direction is left-hand
Conform to the standard of JB/T 1472-1994
