くないものであつた。 Conventionally, as a torsional damper that absorbs torsional vibrations generated in a rotating shaft, a vibration ring 3 is attached and fixed to the outer periphery of a sheet metal hub 1 via an annular rubber 2, as shown in FIGS. 1 and 2. A type of hub 1 is used in which the hub 1 is attached to the tip of the rotating shaft 6 as shown in the figure, but this type of hub has a configuration in which the tip of the sheet metal hub 1 is parallel to the central axis of the torsional damper. ing. Therefore, in the conventional torsional damper, there is no part to prevent the vibration ring 3 from coming off when it comes off, and the vibration ring 3
This had the disadvantage that the engine would fly out to the front (to the left in the figure, that is, to the outside of the engine), which was unfavorable from a safety standpoint.

を阻止する構成としたものである。 The present invention aims to eliminate the above-mentioned drawbacks and provide a highly safe torsional damper with a structure that prevents the vibration ring from coming off from the sheet metal hub. The tip on the opposite side is bent toward the outer diameter side, and the bent end is brought into contact with the outer end of the vibration ring inserted through an annular rubber to prevent the vibration ring from jumping out to the outside of the engine. be.

底壁に穿設した取付孔である。 Hereinafter, one embodiment of the torsional damper of the present invention will be described with reference to FIG. Projection strip 1b
Furthermore, an abutting peripheral edge 4 bent in the outer circumferential direction is formed at the tip of the peripheral cylinder 1a, which is disposed on the opposite side in the axial direction to the side to which the rotating shaft 6 is attached. A metal vibrating ring 3 is externally fitted onto the circumferential cylinder 1a of the sheet metal hub 1 via an annular rubber 2 made of an annular elastic body, and the sheet metal hub 1 is fitted onto the inner peripheral surface of the vibrating ring 3. A concave circumferential groove 3a is formed at a position corresponding to the circumferential groove 1b formed on the circumferential tube 1a, and the circumferential groove 1a is
The outer diameter dimension D 1 of b is smaller than the inner diameter dimension D 2 of the vibration ring 3, and the annular rubber 2 is closely inserted along the curved gap between the protruding circumferential strip 1b and the concave circumferential groove 3a. Further, the outer diameter dimension D 3 of the abutting peripheral edge 4 is configured to be slightly larger than the inner diameter dimension D 2 of the vibration ring 3. In addition, 5 in the figure is a mounting hole bored in the bottom wall of the sheet metal hub 1.

好ましい構造を構成するものである。 The torsional damper having the above structure is used by being fixedly attached to the end of the rotating shaft 6 using the mounting hole 5 of the sheet metal hub 1, and the torsional vibration of the rotating shaft 6 is absorbed by the inertia of the vibration ring 3 and the elasticity of the annular rubber 2. It is something that absorbs
Even if the fitting force of the vibrating ring 3 is loosened due to some factor such as deterioration or breakage of the annular rubber 2 during use and a pulling force is generated in the direction of the arrow, the abutting peripheral edge 4 of the sheet metal hub 1 will not touch the outer end surface 3b of the vibrating ring 3. Since the vibrating ring 3 comes into contact with the vibrating ring 3 and prevents it from coming off, the vibrating ring 3 does not protrude forward (toward the outside of the engine), which is a desirable structure in terms of safety.

い。 As described above, according to the present invention, in a torsional damper in which a vibration ring is extrapolated to a sheet metal hub via an annular rubber, the vibration ring does not come out and pop out, so it is possible to provide a torsional damper with excellent safety. , The practical effects of this invention are extremely large.
