Embodiment
The present invention is described in further details with reference to the accompanying drawings and detailed description.
As shown in Figure 1 and Figure 2, torsion Vibration draw bail embodiment one of the invention couples including the first connector 1, second
Part 2 and the elastic component 4 that can transmit moment of torsion, elastic component 4 are connected between the first connector 1, the second connector 2, the first connection
Part 1, the second connector 2 are used to couple different Axle Parts, to realize the present embodiment as the function of shafting coupling member.
Preferably, which rolls spring for one, and more specifically, as shown in Figures 2 and 3, this rolls spring as one
Tower spring, has inner ring 5 and outer ring 6.First connector 1, the second connector 2 are flange, it is very convenient in the portion such as axis
The end flanges connection of part.The both ends of elastic component 4 are then individually fixed in the first connector 1, the opposite flank of the second connector 2
On.Feature is rolled due to tower spring, the inner ring 5 of elastic component 4 can also be referred to as, outer ring 6 is individually fixed in the first connection
Part 1, the second connector 2 side on.
Further, weld connection between the first connector 1, the side of the second connector 2 and elastic component 4, for example, laser
Welding.As shown in Figure 1,4 and first connector 1 of elastic component, 2 coupled position of the second connector are equipped with weld seam 7, the end of elastic component 4
Portion's first lap can use the welding manner of 360 degree of zero pitch of whole circle, be connected as welding surface with connector side.Preferably,
Elastic component 4 is the wire rod or plate of spring steel material, and the selection of Welding that the junction of itself and connector uses regards structural member
Geometric scale depending on, scale is smaller, more tends to Laser Welding, otherwise is exactly conventional weld.
Embodiment illustrated in fig. 1 one can resist twisting vibration and axial vibration at the same time.The first connector 1 when its both ends,
Two connectors 2 stop when reason produces relative rotation acceleration because vibrating, opening, its both ends can produce rotating torque, produce change
Shape, deformation drag square is always with rotating torque direction on the contrary, so as to produce the effect for suppressing to rotate.Rotating torque direction in theory
Unrestricted, in practice, when elastic component 4 is tower spring, rotating torque direction is identical with the wind spring hand of spiral to be preferred.
When applying the present invention to shaft coupling occasion：If axial load need not be born, can be used following has flat
The torsion Vibration draw bail embodiment two of the invention of spring；If desired axial load is born, can be used with tower spring
The torsion Vibration draw bail embodiment one of the present invention.As shown in Fig. 2, the spring total height of elastic component 4 is H, two adjacent rings spring
Difference in height is h, and spring anti-twisting property reduces with the increase of h, bears axial load ability and increases with the increase of H.Used in connection
During axis occasion, it is necessary to, the torsion stiffness of elastic component 4 need to be not less than the torque value of shafting transmission.
The structure of the torsion Vibration draw bail embodiment two of the present invention is more similar to embodiment one, and difference is,
Elastic component 3 between two connectors rolls spring to be another form of：Flat spring.As shown in figure 4, the flat spring has
There are inner ring 5, outer ring 6 (Fig. 3 is also the right view of Fig. 4), when being welded with connector, the two difference laser welding is in the first connection
The medial surface of part, the second connector.Flat spring described in the present invention is the phase of its flat spring for tower spring
Difference in height is highly not present in adjacent two coil springs；That is the both ends of flat spring are concordant setting.
When applied to Axile connection structure, the spring rotation direction of elastic component 3 should be consistent with rotor rotation direction.As it was previously stated,
During applied to shaft coupling occasion, if axial load need not be born, flat spring can be used, otherwise, above-described embodiment should be used
One.
The present invention also provides a kind of torsion Vibration sleeve rotor constructive embodiment, as shown in figure 5, the embodiment includes hollow turn
Sub- body 8, the cylindrical elastomeric part 9 for avoiding torsional oscillation, elastic component 9 is fixed on inside sleeve rotor body 8, and 9 He of elastic component
Sleeve rotor body 8 is coaxial.
Again as shown in figure 5, elastic component 9 is tower spring, its inner ring, outer ring are respectively welded in 8 both ends of sleeve rotor body
Corresponding construction on, the distribution on the outside of 9 both ends of elastic component of weld seam 7.Specifically, 8 both ends of sleeve rotor body are open-minded respectively
Hole (unmarked), through-hole diameter match with 9 Internal and external cycle outside diameter of elastic component, directly weld the two on the outside of end face respectively,
The position of weld seam 7 is shown in figure at this time.Preferably, the 8 advance chamfering of end face through hole inner radius of sleeve rotor body, convenient weldering
Connect.
Embodiment illustrated in fig. 5 is suitably applied single shaft sleeve rotor torsion Vibration occasion, in application, its tower spring reverses just
Degree is not less than the static twist rigidity of sleeve rotor body 8, and spring rotation direction is preferably consistent with rotor rotation direction.Sleeve rotor sheet
Body 8 has the trend of itself torsional oscillation or torsional deflection when working, sleeve rotor body 8 occurs from when turning round, and elastic component 9 produces torque
Process, 9 interaction process of the process of torque transmission, torque and elastic component, until be suppressed offset process with Fig. 1
The description of shown embodiment is similar, and details are not described herein.
In conclusion the configuration of the present invention is simple, technique are simple, it can effectively suppress shafting torsional oscillation, axial vibration.Using wide
It is general, transmit occasion or single hollow rotor suitable for shaft coupling power.
