Abstract

PURPOSE:To protect the shaft and the peripheral part of a fastening device by positively generating a slip between a shaft to be fastened and the inner wheel of a fastening device, in a fastening device to fasten together the shaft and the rotary body by axially joining taper surfaces thereof in a wedge-form manner. CONSTITUTION:In a fastening device 10, taper surfaces 11 and 13 are axially joined in a wedge-form manner to fasten together a shaft A and a rotary body B. The fastening device 10 has its inner ring 12 provided with a frictional member 19 attached on its inner peripheral surface. When an excessive load is generated on the moved sides of the shaft A and the rotary body B, a slip is generated between the inner peripheral surface of the frictional member 19 and the surface of the shaft A. This constitution protects the shaft A. Parts on the periphery are protected by setting the maximum torque by which a slip is generated.

However, in the conventional device of this kind, only fastening the shaft A and the rotating body B firmly (that is, rigidly) is considered, and slippage occurs between them. Has not been addressed. However, in an actual use mode, slippage may occur between the inner peripheral surface of the inner ring 32 and the surface of the shaft A when an overload occurs on the driven side. However, on the inner peripheral surface of the inner ring 32 and the surface of the shaft A, the metals have high surface pressure (20 kg per square millimeter).
Since they are in direct contact at about f), if slippage occurs between them, the contact surface will be damaged. Once such a situation occurs, the fastening device itself becomes unusable due to seizure of the metal surface, or it can be reused but the same transmission torque can be obtained even if the fastening bolts are tightened with the same tightening force. There was a problem that I could not get. The present invention intends to solve the above-mentioned problems in this type of fastening device by positively causing a slip between the shaft and the inner ring for a torque exceeding a certain limit.

According to the present invention, a wedge action is caused between an inner ring and an outer ring having a tapered surface by a fastening force axially acting in a boss hole provided in a rotating body, and thereby a diameter is generated. In a taper ring type fastening device for generating a directional tightening force to fasten the rotating body to a shaft, a friction material is fixed to the inner peripheral surface of the inner ring to prevent the shaft and the friction material from exceeding a certain torque. The above-mentioned problems have been solved by a tapering type fastening device that causes slippage between the two.

When the torque exceeds the torque that can be transmitted between the shaft and the inner ring, the shaft slides on the friction material.
However, this is not slippage between metal surfaces under a high surface pressure, but slippage of the metal surface with respect to the friction material, so that the shaft surface is not seriously damaged as in the past. Thus, the tapering type fastening device can be made to have the function of the torque limiter. It can be used repeatedly.
