Definitions
- the present invention relates to a boot ring of a constant velocity joint used in a vehicle such as an automobile.
- constant velocity joints are used as joints for transmitting the driving force of an engine from a drive shaft to a driven shaft.
- the joint part of the bearing structure that connects the drive shaft and the driven shaft is covered with a bellows-shaped boot filled with grease, and when the vehicle turns, the connection angle between the drive shaft and the driven shaft changes.
- the driving force is transmitted from the driving shaft to the driven shaft.
- the boots are fitted with seal portions at both ends into fitting portions formed on a case of a constant velocity joint or a drive shaft, and a metal boot ring called a clamp is tightened from the outer periphery by a tightening machine or the like. It is fixed to a constant velocity joint by tightening it outside the seal part.

As shown in Fig. 2, the boot ring 10 is formed with a female key portion 12 and a female key portion 12 on both ends of a strip cut to a predetermined length, and the belt material is formed into a ring shape. After processing, the female key portion 11 and the female key portion 12 are vertically overlapped and engaged with each other.
- the boot ring 10 can be manufactured as follows. Immediately, the strip cut to a predetermined length is processed into an unconnected ring shape, and the strip is overlapped at a predetermined length at both ends. Then, the overlapped portion is processed by using a die and a punch into a so-called half-punch, which is a state in which a punch is normally defective. Thereby, the female key part 11 and the female key part 12 are processed, and as shown in FIG. 1, the female key part 11 and the female key part 12 are manufactured in a connected state. .
