Driven Gear - Fine Blanking Product
[ What is a driven gear? ]
When two gears are meshed, the gear moved by the other one is called the "driven gear".
The other one is called the "drive gear".
The gears in the photo are for two-wheeled vehicles and are stamped with a fine blanking die.
[ Sample product specifications of sub-balancer and driven gear ]
- Workpiece material: SCM415HV
- Product size: φ110mm
- Thickness: 5.2mm
- Press: FB400 ton
[ Features ]
- The rectangular holes are just there to reduce the part weight and therefore the dimensional precision required is not so high. However, the gear part needs to have a 100% sheared surface and the profile of the involute part is also strictly controlled.
- The punch/die clearance is maintained at 10μm for the gear and the central hole.
- A V-shaped protrusion on the die is used in order to minimize the die-roll at less than 20%.
- A special radius is set on the dies cutting edges in order to reduce the burrs to a size where they can be removed in a separated process.
- The sides of the die and of the central hole punch are polished to a mirror finish, resulting in a surface roughness of the sheared surface also as smooth as a mirror.
