As shown in Figure 3, on the inner peripheral surface of wheel rim 14, be provided with circular groove 20, the width of setting is a bit larger tham trip ring 22, and trip ring 22 is processed to do the rectangle with bottom surface of face contact.
In the embodiment of Fig. 1 to Fig. 3, this trip ring whirl-stop device 24 by in the circular groove 20 that is fixed on gear body 18 and 26 of spline parts (spline piece) that embed the opening portion 22a of trip ring 22 form.This spline parts 26 can adopt slug to make, as bloom etc.
Thus, if spline parts 26 are positioned in the middle of the opening portion 22a of trip ring 22, according to said method be fixed in the circular groove 20, even then gear body 18 is subjected to turning round the influence of variation, trip ring 22 can along the circumferential direction not rotate in circular groove 20 independently yet, thereby can not produce wear phenomenon between trip ring 22 and circular groove 20 bottom surfaces.On the other hand, be delivered to the vibration (with reference to the F ' of Fig. 1) of gear body 18 axial directions, can under 20 pairs of circular grooves of trip ring, 20 friction displacement states, be inhibited.Thereby, can reduce the wearing and tearing of gear body 18 trip rings 22, keep gear 10 working life over a long time.
In the embodiment of Fig. 4 and Fig. 5, trip ring whirl-stop device 24 inserts recess 20b by 2 edges to be formed, and the edge 22b of the opening portion 22a of its trip ring 22 is inserted on the bottom surface 20a of circular groove 20 of gear body 18.Therefore the clearance G of the opening portion 22a of trip ring 22 is generally 4～10mm, and the interval of inserting recess 20b, 2 edges also is set in the scope that conforms to the gap of the opening portion 22a of its trip ring 22.
As previously mentioned, when trip ring 22 unclamped in its opening portion 22a being drawn in back insertion circular groove 20 again, because the elasticity of itself makes it expand towards the diametric outside, edge 22b was embedded into the edge and inserts in the recess 20b.Thereby even gear body 18 is subjected to the influence of rotation change, trip ring 22 can not rotate along its circumferencial direction in circular groove 20 independently yet, and can not produce the phenomenon of wearing and tearing between trip ring 22 and circular groove 20 bottom surfaces yet.On the other hand, be delivered to the vibration of the axial direction of gear body 18, can under the state of 22 pairs of circular grooves of trip ring, 20 friction displacements, be inhibited.Thereby, the same with the embodiment of Fig. 1 to Fig. 3, can reduce the wearing and tearing between gear body 18 and the trip ring 22, keep gear 10 working life over a long time.
In the embodiment of Fig. 6, the elastic joint part 28 that trip ring whirl-stop device 24 is formed by the inner side surface of the annular slot 20 of two sides of crossing trip ring 22 and gear body 18 is formed.The back adds the sulphur shaping to rubber in circular groove 20 in circular groove 20 that trip ring 22 is packed into, just can be made into this elastic joint part 28.This elastic joint part 28 both can form along the circumferential surface of full annular groove 20, also can form at regular intervals in a circumferential direction.
Because can making in the circular groove 20 of trip ring 22 and gear body 18, this nonrigid connector 28 is connected as elasticity, even therefore gear body 18 is subjected to the influence of rotation change, trip ring 22 can not rotate along its circumferencial direction in circular groove 20 independently yet, thereby can not produce the phenomenon of wearing and tearing between trip ring 22 and circular groove 20 bottom surfaces yet.On the other hand, be delivered to the vibration of the axial direction of gear body 18, be inhibited under the state of the displacements that can rub in the elasticity of trip ring 22 opposing elastic joint parts 28 and to circular groove 20 works.Thereby, the same with embodiment and Fig. 4 embodiment of Fig. 1 to Fig. 3, can reduce the abrasion of gear body 18 and trip ring 22, keep gear 10 working life over a long time.
Because elastic joint part 28 only has the intrinsic low vibration number of rubber, therefore can not reduce inhibition effect to the vibration of external noise and so on high frequency.
Fig. 7 to Fig. 9 represents another embodiment of gear 10 of the present invention.In this embodiment, trip ring 22 does not contact with circular groove 20 bottom surfaces of gear 18, but suppresses vibration by rubber quality body 34 described later.
