Abstract
The utility model discloses an amortization shock attenuation shaft coupling, it is including initiative end, amortization cover, spring washer and driven end, the initiative end is in the same place with driven end fixed connection, and spring washer sets up between the contact surface of initiative end and driven end, and the amortization ways is established on initiative end and driven end, and the last location strip that is used for assistance -localization real -time that is equipped with of spring washer is equipped with the recess that is used for installing spring washer location strip on initiative end and the driven end, be equipped with a plurality of countersunk screw that are used for fixing a position the axle center position on driving shaft and the driven shaft.
Description
Technical field
The utility model relates to a kind of coupling, has and relates to a kind of silencing and damping coupling.
Background technique
Coupling is used to connection for transmission axle and driven shaft, makes two axles jointly rotate the mechanical parts of transmitting torque; In power transmission at a high speed, coupling also has the effect of the dynamic performance in buffering, damping and raising driving mechanism.Coupling conventional is at present mostly simple due to structure, and also the rigid connection that adopts can produce vibrations and noise after mounting, affects the normal work of equipment and operator; A lot of coupling can not regulate the shaft core position of driving shaft and driven shaft simultaneously.
Model utility content
For above-mentioned deficiency of the prior art, the utility model provides a kind of noise and the vibrations that can reduce rigid connection coupling, and can the silencing and damping coupling of its axle center position.
In order to reach foregoing invention object, the technical solution adopted in the utility model is:
There is provided a kind of silencing and damping coupling, it comprises drive end, noise reduction cover, resilient pad and driven end; Drive end and driven end are fixed together, resilient pad is arranged between drive end and the surface of contact of driven end, noise reduction cover is set on drive end and driven end, resilient pad is provided with the positioning strip for auxiliary positioning, drive end and driven end are provided with the groove for installing resilient pad positioning strip, and driving shaft and driven shaft are provided with some sunk screws for locating shaft core position.On the basis of the first goal of the invention of the present utility model, the second goal of the invention of the present utility model is that the end that drive end contacts with driven end is provided with a protuberance, driven end is provided with the groove matched with protuberance.On the basis of the first goal of the invention of the present utility model, the 3rd goal of the invention of the present utility model is, the material of noise reduction cover is soft material.
On the basis of the first goal of the invention of the present utility model, the 4th goal of the invention of the present utility model is that driving shaft and driven shaft all adopt Spielpassung.
The beneficial effects of the utility model are: by the resilient pad arranged between drive end and driven end surface of contact, make coupling not change on the basis of original structure, utilize the elasticity of self to improve antidetonation and the noise reduction of structure; Noise reduction cover ensure that the axle center of driving shaft and driven shaft on the same line, the axle center of two axles can not be offset, also improve the transmission stability of structure; Sunk screw can regulate the shaft core position of driving shaft and driven shaft easily.

Fig. 1 is the structural representation of silencing and damping coupling.
Wherein, 1, driving shaft; 2, drive end; 3, noise reduction cover; 4, resilient pad; 5, driven shaft; 6, sunk screw; 7, driven end.
Embodiment
Below embodiment of the present utility model is described; so that those skilled in the art understand the utility model; but should be clear; the utility model is not limited to the scope of embodiment; to those skilled in the art; as long as various change to limit and in the spirit and scope of the present utility model determined, these changes are apparent, and all innovation and creation utilizing the utility model to conceive are all at the row of protection in appended claim.
As shown in Figure 1, this silencing and damping coupling comprises drive end 2, noise reduction cover 3, resilient pad 4 and driven end 7; Drive end 2 and driven end 7 are fixed together, and resilient pad 4 is arranged between the surface of contact of drive end 2 and driven end 7, avoid the direct hard contact of surface of contact of drive end 2 and driven end 7, eliminate partial noise and the vibrations of rigid connection.
Noise reduction cover 3 is set on drive end 2 and driven end 7, and the junction surface place deadened from drive end 2 and driven end 7 is transmitted to outside noise, further enhances the elimination to noise.
The material of noise reduction cover 3 is soft material, can realize not dismantling easily by instrument on the one hand, noise reduction cover 3 also can be allowed on the other hand to be close to the outer surface of drive end 2 and driven end 7, move with drive end 2 together with driven end 7.In addition, because 3 flexibles are overlapped in noise reduction, drive end 2 and driven end 7 have rich activity space to be more conducive to giving full play to of resilient pad 4 performance in the axial direction in the axial direction.
Resilient pad 4 is provided with the positioning strip for auxiliary positioning, drive end 2 and driven end 7 are provided with the groove for installing resilient pad 4 positioning strip, prevent resilient pad 4 from affecting the normal operation of equipment when coupling works due to sideslip or producing extra noise.
Driving shaft 1 and driven shaft 5 are provided with some sunk screws 6 for locating shaft core position, and driving shaft 1 and driven shaft 5 all adopt Spielpassung.Because driving shaft 1 and driven shaft 5 all adopt Spielpassung, therefore can finely tune the shaft core position be arranged on driving shaft 1 and driven shaft 5 by regulating the sunk screw 6 be distributed on driving shaft 1 and driven shaft 5, allow driving shaft 1 and driven shaft 5 axle center point-blank, reduce the asynchronous caused noise of the rotation brought because axle center is unjustified and vibrations.The end that drive end 2 contacts with driven end 7 is provided with a protuberance, driven end 7 is provided with the groove matched with protuberance, protuberance and fit depressions transferring power.
