＜deceleration side 〉
Referring to figs. 1 through Fig. 3, when slowing down, the rotating power of the input shaft 5 of speed changer is delivered to hub member 30, dish member 27, helical spring 28, the pre-damping of 29(section 2 successively), ring element 25,26, flange member 18, another member 20,22, helical spring 19,21(master's damping section 3), seat member 20,22, side plate 15,16, connector element 17, disc spring 12, rivet 13,14, liner 10,11, and be passed to the bent axle of motor.
At this moment, when between hub member 30 and liner 10,11, producing when reversing (reversing of deceleration side), pre-damping section 2 absorbs the change moment of torsion that produces because of reversing of initial stage, and reverse and pre-damping section 2 can not absorb the time further producing, namely, contact and when having limited pre-damping section 2 and reversing at the tooth of the 18c of internal spline section of the tooth of the 30b of external splines section of hub member 30 and flange member 18, main damping section 3 absorbs because reversing the change moment of torsion that produces.Main damping section 3 is reversed, until the jut 20a of seat member 20 is against each other.Produce when reversing to deceleration side in main damping section 3, in retardation section 4, producing respectively outside the slip on the bearing surface between bearing surface between thrust component 31 and the hub member 30 and thrust component 32 and the hub member 30, only produce slip at two slip surface E, F, and do not produce slide (with reference to Fig. 5) at slip surface A, B, C, D.
In addition, when main damping section 3 is reversed to deceleration side, with regard to control panel 44, extend on the circumferential end faces of the 18a of window section that flange member 18 and the claw 44a of seat between the member 20 be not stuck in flange member 18, the circumferential end faces of the 18a of window section of flange member 18 is separated with claw 44a, the state that claw 44a keeps and seat member 20 connects, the seat member 20 that connects with claw 44a and side plate 15,16 the 15a of window section, the rotation of 16a one, so control panel 44 and side plate 15, be rotated 16 rotary synchronous.In addition, produce when reversing to deceleration side in main damping section 3, thrust component 47 can not with control panel 44 relative rotations, and this control panel 44 and side plate 15,16 rotary synchronous, so thrust component 47 and side plate 15, be rotated 16 rotary synchronous.And, be rotated the rotary synchronous of thrust component 43, thrust component 45 and belleville spring 46 and side plate 16.Therefore, produce when reversing to deceleration side in main damping section 3, be rotated thrust component 43, control panel 44, thrust component 45, belleville spring 46, thrust component 47 and side plate 15,16 rotary synchronous.Therefore, when reversing to deceleration side in main damping section 3, do not produce slip at slip surface A, B, C, D.
In addition, when main damping section 3 is reversed to deceleration side, before the tooth butt of the 18c of internal spline section of the tooth of the 30b of external splines section of hub member 30 and flange member 18, in pre-damping section 2, only there is helical spring 28 to work, and since the periphery jut 27b of dish member 27 not with helical spring 29 butts, so helical spring 29 is inoperative.
According to the first embodiment, bring into play following effect.
The first, will be stoped the thrust component 47 of rotation to be configured between belleville spring 46 and the side plate 16 by the front end of the rotation prevention portion 44b of control panel 44, the rubbing surface number can be increased thus and rubbing surface can be effectively utilized.Especially, be that 4 faces are compared with the rubbing surface of prior art, can make rubbing surface in the first embodiment is 6 faces, wherein, take the rubbing surface of heavy load effect as 4 faces (slip surface A, B, C, D), take the rubbing surface of little load effect as two faces (slip surface E, F).
The second, in retardation section 4, between side plate 15,16, have two belleville springs 41,46, therefore can make the setting to the retardation of acceleration and deceleration have degrees of freedom.
The 3rd, when reversing to acceleration side in main damping section 3, can guarantee control panel 44 and thrust component 47 two sides separately as rubbing surface (slip surface), therefore can increase the rubbing surface number by enough few parts, thus the increase of the thickness on can suppressing axially.
The 4th, the member of the rubbing surface in retardation section 4 (slip surface) uses peucinous thrust component 40,43,45,47,48, is conducive to thus prevent from wearing out in time.In addition, the rubbing surface in retardation section 4 (slip surface) carries out the surface treatment of zinc-coated etc., can suppress thus the reduction of initial stage friction factor.
The 5th, compared with prior art, can guarantee on the basis, space-efficient highly stable acceleration side retardation.In addition, by adopting this structure, can be corresponding with the trend of the pressurized machine of from now on motor and float tolerance.
In addition, can be in whole disclosures of the present utility model scope of (comprising claims and accompanying drawing), and then based on its basic fundamental thought, mode of execution is changed and adjusts to embodiment.In addition, in the scope of claims of the present utility model, can carry out various combinations or selection to each open key element (comprising each key element of each claim, each key element of each embodiment, each key element of each accompanying drawing etc.).That is, the utility model obviously comprises those skilled in the art and can all openly reach various distortion, the correction that technological thought obtains according to what comprise claims.
