Definitions
- the present invention relates to a buffer stopper having both a buffer function and a stopper function.
- the buffer stopper of the present invention is incorporated in a steering device or the like in the field of automobile equipment, or used in the field of industrial equipment, for example.
- a buffer stopper 51 shown in FIG. 2 is known, and this buffer stopper 51 is mounted in a space between an end surface portion 63 provided on the housing 61 side and an end surface portion 73 provided on the shaft 71 side.
- this buffer stopper 51 is composed of a combination of a metal fitting 52 held by the end surface portion 73 on the shaft 71 side and an elastic body 53 connected to the metal fitting 52.
- the shaft 71 is assumed to be displaced relative to the housing 61 in the axial direction.
- the elastic body 53 is in contact with the end surface portion 63 on the housing 61 side so as to be able to contact and separate.
- a metal fitting 54 is connected to the distal end side of the elastic body 53, and the elastic body 53 is connected between a pair of metal fittings 52, 54. It is possible to compress and deform.
- the buffer stopper 51 is fixed to the housing 61 side, and when the shaft 71 is displaced, the end surface portion 73 on the shaft 71 side collides with the metal fitting 54.
- the metal fitting 54 has high friction due to its material and is difficult to smoothly slide with respect to the end surface portion 73 on the shaft 71 side.
- the buffer stopper 51 of FIG. 3 when used in a mechanism in which the housing 61 and the shaft 71 rotate relative to each other, the metal member 54 does not slide smoothly, and the elastic body 53 is twisted. 53 may be damaged.
- the use of the buffer stopper 51 of FIG. 3 is limited to a mechanism in which the housing 61 and the shaft 71 are relatively displaced in the axial direction, and the housing 61 and the shaft 71 are relatively displaced in the axial direction and are relatively rotated. It cannot be used for.
- the present invention is not limited to a mechanism in which the housing and the shaft are relatively displaced in the axial direction, and may be used for a mechanism in which the housing and the shaft are relatively displaced in the axial direction and the housing and the shaft are relatively rotated.
- An object of the present invention is to provide a buffer stopper that can be used.
- the buffer stopper according to the present invention is mounted in a space portion between an end surface portion provided on the housing side and an end surface portion provided on the shaft side that is axially displaced and rotated with respect to the housing.
- a buffer stopper comprising: a metal fitting held on any one of the end face portions; an elastic body connected to the metal fitting; and a sliding member connected to the elastic body. Is slidably rotated with respect to the other end surface when the shaft rotates in a state where the sliding member is in contact with the other end surface. It is made possible.
- the sliding member is connected to the elastic body, and the sliding member is brought into contact with the mating part (shaft or housing).
- the sliding member contacts the shaft side and relatively slides and rotates. Accordingly, it becomes difficult for the rotational torque of the shaft to be transmitted to the elastic body.
- the sliding member contacts the housing side and slides and rotates. Therefore, the elastic body easily rotates with the shaft.
- the sliding member is made of a resin part having a lower friction than the metal fitting.
- the mechanism is not limited to a mechanism in which the housing and the shaft are relatively displaced in the axial direction, and the housing and the shaft are relatively displaced in the axial direction and the housing and the shaft are relatively rotated. It is possible to provide a buffer stopper that can also be used in a mechanism that performs the above.
- Sectional drawing which shows mounting
- the present invention includes the following embodiments.
- a material that can slide with low friction for example, polyacetal, polyamide, etc.
- the housing and the shaft rotate relative to each other.
- the mechanism becomes possible.
- energy and vibration can be absorbed and reduced even by a mechanism in which the housing and the shaft rotate relative to each other by applying a material that can slide with low friction to the ring. Has performance. Further, energy and vibration can be reduced not only in the axial direction and the rotational direction but also in complex input.
- the buffer stopper 11 As shown in FIG. 1A, the buffer stopper 11 according to this embodiment is inserted into the end surface portion 63 provided at the back end portion of the shaft hole 62 of the housing 61 and the shaft hole 62 and to the housing 61. It is mounted in a space between the end surface portion 73 provided at the tip of the shaft 71 that is displaced in the axial direction and rotates.
- the buffer stopper 11 is fixed to the housing 61 and is held by the end surface portion 63 on the housing side, a flat plate-like metal fitting 12, an annular elastic body 13 made of a rubber-like elastic body connected to the metal fitting 12, and an elastic member. And a sliding member 14 connected to the body 13.
- the sliding member 14 is formed in an annular shape by a resin part having a low friction compared to the metal fitting.
- the resin material include polyacetal or polyamide.
- the sliding member 14 comes into contact with the shaft 71 so as to be able to come into contact with and separate from the shaft 71, and can smoothly slide and rotate with respect to the shaft 71 when the shaft 71 rotates while the sliding member 14 is in contact with the shaft 71. For this reason, it has an axially perpendicular end surface 14a that can contact and slide with respect to the end surface portion 73 on the shaft side.
- the buffer stopper 11 may be fixed to the shaft 71 side, that is, a flat plate-shaped metal fixture fixed to the shaft 71 and held by the end surface portion 73 on the shaft side. 12, an annular elastic body 13 made of a rubber-like elastic body connected to the metal fitting 12, and a sliding member 14 connected to the elastic body 13.
