Patent describes a kind of vibration damping joint, imitative gigot joint of inventing design based on sheep extremities joint living model, wherein the torsion spring 10 of energy storage effect is equivalent to the muscle model of sheep four limbs, and the frictional damping of recessed axle sleeve 8 and convex axle sleeve 11 surface of contact is equivalent to the frictional damping model in gigot articular cavity.Based on the damping behavior of sheep extremities joint, the utility model bionic joint also possesses vibration isolation and damping characteristic.
The main constituent elements in vibration damping joint, a kind of imitative gigot joint of the utility model has: shangguan pole 7, ShiShimonoseki pole 12, joint shaft 18, torsion spring 10, convex axle sleeve 11, recessed axle sleeve 8, headless screw 6 left end cap 4, right end cap 14, left dust cover 1, right dust cover 17, left standard hex flange surface nut 2, right standard hex flange surface nut 16, left normal rated thrust ball bearing 3, right normal rated thrust ball bearing 15, left standard roller bearing 5, right standard roller bearing 13, standard hexagon socket cap head screw 9, headless screw 6.Recessed axle sleeve 8 fits tightly with the inclined-plane of convex axle sleeve 11, and recessed axle sleeve 8 is socketed on joint shaft 18 with convex axle sleeve 11, recessed axle sleeve 8 outer (left side) end is fixedly connected with shangguan pole 7 by standard hexagon socket cap head screw 9, convex axle sleeve 11 outer (right side) end is fixedly connected with ShiShimonoseki pole 12 by standard hexagon socket cap head screw 9, and torsion spring 10 is wrapped in concavo-convex axle sleeve periphery and torsion spring 10 two ends are connected with shangguan pole 7 and ShiShimonoseki pole 12 respectively by headless screw 6.This vibration damping joint, imitative gigot joint is structurally arranged symmetrically with, for representing their assembly relations, choose left side structure to be described: between shangguan pole 7 and joint shaft 18, be equipped with left standard roller bearing 5, transmitting force is needed and for ease of dismounting between joint shaft 18 and left standard roller bearing 5 inner ring, therefore Spielpassung is adopted, outer ring and the shangguan pole 7 of left standard roller bearing 5 adopt interference fit, do not need frequent dismounting.Add pad in right amount between left end cap 4 and outer (left side) end face of shangguan pole 7, left thrust ball bearing 3 and left end cap 4 fit tightly.The left hexagon nut with flange 2 that pressed against left thrust ball bearing 3 is tightened in joint shaft 18 left end threaded end, left hexagon nut with flange 2 can be realized by the pretightening force changing left hexagon nut with flange 2 thrust of left thrust ball bearing 3, this thrust via left end cap 4 and shangguan pole 7, be passed on the surface of contact of recessed axle sleeve 8 and convex axle sleeve 11, by changing this power, the positive pressure between recessed axle sleeve 8 and convex axle sleeve 11 can be changed, thus the frictional force changed between recessed axle sleeve 8 and convex axle sleeve 11, and then produce different frictional damping effects.Be threaded between left dust cover 1 and left end cap 4.
Vibration attenuation mechanism of the present utility model is: spring and damping vibration attenuation mechanism in parallel, and wherein torsion spring 10 assume responsibility for energy storage effect, and in movement process, first energy-absorbing releases energy again, and continuous this process of circulation, generally not consumed energy.Damping wherein assume responsibility for power consumption effect, and the namely frictional damping of surface of contact between recessed axle sleeve 8 and convex axle sleeve 11, sprays different friction materials at this surface of contact, can friction factor be changed, be known by f=μ N, change coefficientoffrictionμ, frictional force f changes, and corresponding frictional damping value also changes.The positive pressure N simultaneously changed wherein also can change frictional force, positive pressure N is wherein the component of pretightening force F, this pretightening force is determined by left standard hex flange surface nut 2, positive pressure size N=Fsin θ simultaneously, wherein θ is the inclination angle of inclined plane of recessed axle sleeve 8 and convex axle sleeve 11 surface of contact, θ≤90 °, adjustment inclination angle of inclined plane θ, also can change frictional force.Described on end, by changing inclination angle theta, change pretightening force F and coefficientoffrictionμ three kinds of modes can change damping size, realize the adjustable of passive energy dissipation effect.
Working procedure of the present utility model: shangguan pole 7 connects upper mounting plate or other connected elements, and ShiShimonoseki pole 12 connects supporting foot or miscellaneous part.Because this structure plays upper and lower holding power, when the change of forces occurring, joint shaft place just produces moment of torsion, moment of torsion orders about torsion spring 10 and is out of shape, torsion spring 10 carries out energy storage, simultaneously due to recessed axle sleeve 8 and convex axle sleeve 11 contact surface frictional damping effect, rubbing surface carries out Conversion of Energy, is heat energy by kinetic transformation.By the acting in conjunction of torsion spring 10 and frictional damping, kinetic energy significantly weakens, and oscillation function also significantly weakens, thus this joint has damping behavior.
First shangguan pole 7 and recessed axle sleeve 8 are carried out cooperation during assembling to install, and then left roller bearing 5 is installed on shangguan pole 7, and then joint shaft 18 is carried out cooperation installation through left roller bearing 5, then just left end cap 4 and left thrust ball bearing 3 are installed, also be in like manner first by ShiShimonoseki pole 12 on one side in addition, right roller bearing 13 and convex axle sleeve 11 coordinate to be installed, then their are being combined on the joint shaft 18 of one end before torsion spring 10 is assemblied in, and allow the rubbing surface of recessed axle sleeve 8 and convex axle sleeve 11 fit, then left end cap 4 is refilled, right end cap 14, left thrust ball bearing 3 and right thrust ball bearing 15, finally carry out left hexagon nut with flange 2 and right hexagon nut with flange 16 tightening installation, set initial pretightening force, and then by left dust cover 1, right dust cover 17 rotates and is mounted to two ends, finally torsion spring 10 two ends headless screw 6 is carried out initial position, so far end is assembled.
By reference to the accompanying drawings embodiment of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
