Abstract
The utility model provides a middle device of a damping coupler. The middle device of the damping coupler comprises a hard middle body, a first soft middle body and a second soft middle body, wherein the hard middle body is arranged between the first soft middle body and the second soft middle body, round through holes are formed in the middle portion of the hard middle body, the center of the first soft middle body and the center of the second soft middle body respectively, clamping ring holes are formed evenly in the portions, around the through holes, of the hard middle body, the first soft middle body and the second soft middle body respectively, the holes in the hard middle body, the first soft middle body and the second soft middle body correspond in a one-to-one mode, both the first soft middle body and the second soft middle body are made of nitrile rubber, and the overall thickness of the middle device ranges from 6 cm to 10 cm, the thickness ratio of the first soft middle body, the hard middle body and the second soft middle body is 1:4:1. The middle device of the damping coupler has the advantages that pressure borne by a damper is reduced, the damping effect is remarkable, and harm caused by resonance is effectively restrained; the clamping ring holes are in the shape enabling the contact area between the clamping ring holes and clamping blocks at the two ends to be maximum, in this way, larger friction force can be generated, and the two ends and the middle device can be combined more conveniently.
Description
Technical field
The utility model belongs to coupling field, especially relates to a kind of middle device of damping spring coupling.
Background technique
Coupling is mainly used in the connection in mechanical transmission, is the major part in mechanical transmission, and working is that connection driving shaft and driven shaft move and moment of torsion to transmit, compensation, due to foozle, is installed inclined to one side error, the bias that after carrying, distortion and the variation of temperature cause, drift angle, axial displacement, existing coupling, compensation is eccentric, drift angle, the poor performance of axial displacement, the life-span is short, has back clearance.Be inconvenient to install and dismantle.The intermediate portion of existing damping spring coupling is generally hard, and itself and axle easily produce resonance, and all can reduce the working life of axle and coupling.
Summary of the invention
The purpose of this utility model is to provide a kind of middle device that can reduce the damping spring coupling resonating between axle and coupling, and especially applicable motor shaft is connected with leading screw.
The technical solution of the utility model is: a kind of middle device of damping spring coupling, comprise hard intermediate, the first soft intermediate and the second soft intermediate, described hard intermediate is located in the middle of the first soft intermediate and the second soft intermediate, hard intermediate, the first soft intermediate, the intermediate portion of the second soft intermediate is equipped with circular through hole, on soft intermediate, beyond through hole, uniform array is provided with several snap ring holes, and the position of the through hole of three parts is corresponding one by one, on hard intermediate, beyond through hole, two sides at position are provided with the annular groove corresponding with the snap ring hole of soft intermediate, the position of the annular groove of two sides of hard intermediate is interlaced, the material of described the first soft intermediate and the second soft intermediate is nitrile butadiene rubber material, the general thickness of middle device is 6-10cm, described the first soft intermediate, the Thickness Ratio of hard intermediate and the second soft intermediate is 1:4:1.
Preferably, described snap ring hole is shaped as fan-shaped that four camber lines surround.
Preferably, the shape of described annular groove is identical with the shape in snap ring hole.
Preferably, the number in described snap ring hole is 3.
Preferably, the diameter of through hole is 1:6 with the ratio of middle device diameter.
Preferably, the general thickness of described middle device is 8cm.
Advantage and the good effect that the utlity model has are: on described coupling, the design of two soft intermediates of a hard intermediate reduces the pressure that bears of damper to greatest extent, and damping is obvious, and effectively suppress the effect of the harm that resonance causes; The setting of snap ring hole shape can have with the clamp at two ends maximum area of contact, thereby produces larger frictional force, is more conducive to the combination of two-end part and middle device.
