Embodiment
Fig. 1 is the structure diagram of damping shaft 100 in the utility model embodiment.Fig. 1 is refer to, the present embodiment provides one
Kind damping shaft 100, the fixed part 120 being fixedly connected including axis body 110, with axis body 110 and the /V for being arranged at axis body 110
Body 130.The axis body 110 of damping shaft 100 has diametrical elasticity, when axis body 110 and the hole to be assembled of damping shaft 100
During interference fit, damping shaft 100 can be made to generate damping when being rotated about axis, limit body 130 can limit damping shaft 100 and exist
Movement in axial direction avoids axis body 110 is axial from being connected to wall surface and generate excessive damping.
In the present embodiment, the axis body 110 of damping shaft 100 has axial upper first end 110a and second end 110b, axis body
110 first end 110a end faces open up the blind hole of oriented second end 110b extension, and first end 110a end faces be further opened with to
4 bar holes 111 of second end 110b directions extension.Four bar holes 111 will be divided into 4 bullets for forming the side wall of blind hole
Piece 112,4 defines an elastic space 113 jointly around the circumferentially disposed shrapnel 112 of axis body 110, and each shrapnel 112 is in axis
Body 110 radially has certain elasticity.Therefore the axis body 110 of damping shaft 100 can realize interference with the hole of other component
Cooperation, during relative rotation, radially flexible axis body 110 can provide damping.
Further, four shrapnels 112 are set around the axial array of axis body 110, and four bar holes 111 are therefore also in axis body
Array is set in 110 circumferential direction.
It should be appreciated that in the other embodiment of the utility model, the number of shrapnel 112 can carry out according to actual needs
Increase and decrease, can be 2,3 or 4 or more.
In the present embodiment, the axis direction of shrapnel 112 from second end 110b along the axis body 110 of axis body 110 extends to
One end 110a.The lateral surface of shrapnel 112 have side by side parallel set multiple lubrication grooves 114, the extending direction of lubrication groove 114 with
The extending direction of shrapnel 112 is consistent.In the present embodiment, the end of one end 110 first end 110a of perforation axis body of lubrication groove 114
Face, so as to open, lubricant to be facilitated to enter lubrication groove 114 so as to be stored in lubrication groove in certain time from first end 110a
In 114.In the present embodiment, the lubrication groove 114 of spread configuration is formed by circumferentially arranged wavy surface, shrapnel 112
Outer circumferential surface be projected as wave perpendicular to the section of 110 axis of axis body.Such outer circumferential surface reduces axis body 110 and hole
Contact surface during (target location that damping shaft 100 is installed) cooperation, makes damping be unlikely to excessive, is provided simultaneously with storage lubricant
Function.
It should be appreciated that in the other embodiment of the utility model, the shape and extending direction of lubrication groove 114 can have
Changed, for example using V-shaped groove, dovetail groove, half slot etc., the direction that opens up of lubrication groove 114 can be the circumferential direction along axis body 110
Extension is in a certain angle with axial direction.The number of lubrication groove 114 can be 1,2,3 or 3 or more.
Fixed part 120 is in multi-diameter shaft shape, including thicker first axle 122 and the second thinner axis 124.Fixed part 120

Other need component to be mounted to be fixedly connected.Further, fixed part 120 and axis body 110 are coaxial.In order to preferably with its
He is coordinated component, and the cross sectional shape of the second axis 124 is hexagon, and the free end of the second axis 124 has chamfering.
It is to be understood that in the other embodiment of the utility model, fixed part 120 can be the homogeneous axis of thickness.Second axis
124 section is in order to be relatively fixed with component joined together in rotation direction, in its of the utility model for hexagon
In his embodiment, the cross sectional shape of the second axis 124 can be the other shapes such as triangle, rectangle, ellipse, the second axis 124
Outer circumferential surface is unequal apart from its axis.
In the present embodiment, limit body 130 is axis shape, in the elastic space 113 of axis body 110.The one of limit body 130
End is connected to wall surface of the elastic space 113 close to 110 second end 110b of axis body, and the other end of limit body 130 is from elastic space 113
Opening close to 110 first end 110a of axis body is stretched out, and the free end of limit body 130 protrudes from first end 110a end faces.Into one
Step ground, limit body 130 are coaxially disposed with axis body 110.
The effect of limit body 130 is to prevent damping shaft 100 in axial float, the free end of four shrapnels 112 and other
Component generates face contact, generates huge rotary resistance.It is unlikely to generate excessive damping, limit body to preferably carry out /V
130 free end end face is spherical surface.It should be appreciated that in the other embodiment of the utility model, the end of 130 free end of limit body
Face can be other forms that can contact with the pre-contact millet cake of other component such as conical surface, possibly even use it is smaller or
Relatively smooth face contact.
