Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
As shown in Figure 1 and Figure 2, torsion Vibration connecting structure embodiment one of the present invention comprises the first coupling 1, second coupling 2 and can the elastic component 4 of transmitting torque, elastic component 4 is connected between the first coupling 1, second coupling 2, first coupling 1, second coupling 2 for connecting different Axle Parts, to realize the function of the present embodiment as axle system coupling member.
Preferably, this elastic component 4 is one roll spring, and more specifically, as shown in Figures 2 and 3, this rolls spring is a tower spring, has inner ring 5 and outer ring 6.First coupling 1, second coupling 2 is flange, is very conveniently connected with the end flanges of the parts such as axle.The two ends of elastic component 4 are then individually fixed on the opposite flank of the first coupling 1, second coupling 2.Roll feature due to tower spring, also can be referred to as the inner ring 5 of elastic component 4, outer ring 6 is individually fixed on the side of the first coupling 1, second coupling 2.
Further, weld connection between the side of the first coupling 1, second coupling 2 and elastic component 4, such as, laser bonding.As shown in Figure 1, elastic component 4 and the first coupling 1, second coupling 2 coupled position are provided with weld seam 7, and the end first lap of elastic component 4 can adopt the welding manner of a whole circle 360 degree of zero pitch, is connected with coupling side as face of weld.Preferably, elastic component 4 is wire rod or the sheet material of spring steel material, the geometric scale of the selection of Welding TV structure part that the joint of itself and link uses and determining, and yardstick is less, more tends to laser beam welding, otherwise is exactly conventional weldering.
Embodiment illustrated in fig. 1 one can resist torsional vibration and axial vibration simultaneously.When its two ends the first coupling 1, second coupling 2 because of vibration, open the reasons such as & stops produce relative rotation acceleration time, its two ends can produce moment of rotation, produce distortion, deformation resistance square is always contrary with moment of rotation direction, thus produces the effect suppressing to rotate.Moment of rotation direction is unrestricted in theory, and in reality, when elastic component 4 is tower spring, moment of rotation direction is all good with wind spring Hand of spiral mutually.
When applying the present invention to coupling occasion: bear thrust load if do not need, the following torsion Vibration connecting structure embodiment two of the present invention with flat spring can be used; If desired bear thrust load, the torsion Vibration connecting structure embodiment one of the present invention with tower spring can be used.As shown in Figure 2, the spring total height of elastic component 4 is H, and two adjacent rings spring heights difference is h, and spring anti-twisting property reduces with the increase of h, bears thrust load ability and increases with the increase of H.When being used in shaft coupling occasion, necessarily, the torsional stiffness of elastic component 4 need be not less than the torque value that axle system transmits.
The structure of torsion Vibration connecting structure embodiment two of the present invention is more similar with embodiment one, and difference is, what the elastic component 3 between two couplings was another kind of form rolls spring: flat spring.As shown in Figure 4, this flat spring has inner ring 5, outer ring 6 (Fig. 3 is also the right elevation of Fig. 4), and when welding with coupling, the two difference laser bonding is in the inner side surface of the first coupling, the second coupling.The said flat spring of the present invention is for tower spring, and the two adjacent rings spring heights of its flat spring does not exist height difference; That is the two ends of flat spring are concordant setting.
When being applied to Axile connection structure, the spring rotation direction of elastic component 3 should be consistent with rotor turns direction.As previously mentioned, when being applied to coupling occasion, bearing thrust load if do not need, flat spring can be used, otherwise, above-described embodiment one should be used.
The present invention also provides a kind of torsion Vibration sleeve rotor constructive embodiment, as shown in Figure 5, this embodiment comprises sleeve rotor body 8, for avoiding the cylindrical elastomeric part 9 of torsional oscillation, it is inner that elastic component 9 is fixed on sleeve rotor body 8, and elastic component 9 and sleeve rotor body 8 coaxial.
Again as shown in Figure 5, elastic component 9 is tower spring, and its inner ring, outer ring are welded on the corresponding construction at sleeve rotor body 8 two ends respectively, and weld seam 7 distributes around outside elastic component 9 two ends.Specifically, hole (unmarked) is opened at sleeve rotor body 8 two ends respectively, and through-hole diameter mates with elastic component 9 Internal and external cycle external diameter respectively, and directly the two welded outside end face, now the position of weld seam 7 is shown in figure.Preferably, sleeve rotor body 8 end face through hole inner radius chamfering in advance, convenient welding.
Embodiment illustrated in fig. 5 being applicable to, is applied to single shaft sleeve rotor torsion Vibration occasion, and during application, its tower spring torsional stiffness is not less than the static twist rigidity of sleeve rotor body 8, and spring rotation direction is preferably consistent with rotor turns direction.Sleeve rotor body 8 has the trend of self torsional oscillation or torsional deflection when working, sleeve rotor body 8 occurs in time turning round, elastic component 9 produces the process of moment, moment is transmitted process, moment and elastic component 9 interaction process, until the process of suppressed counteracting is similar with the description about the embodiment shown in Fig. 1, do not repeat them here.
In sum, structure of the present invention is simple, technique simple, can effectively suppress shafting torsional oscillation, axial vibration.Be widely used, be applicable to coupling transmission of power occasion or single hollow rotor.
As known by the technical knowledge, the present invention can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Within the scope of the present invention all or be all included in the invention being equal to the change in scope of the present invention.
