Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
Fig. 1 to 4 are schematic structural views of a vibration/noise reduction gear according to the present invention. The vibration and noise reduction gear comprises a gear body 10, a plurality of vibration reduction elements 20 arranged on the gear body 10, and two vibration reduction rings 30 arranged on the gear body 10. It is contemplated that the vibration/noise reduction gear may include other functional structures, such as inner and outer chamfers, keyways, etc., which are well known to those skilled in the art and will not be described herein.
The gear body 10 comprises a body 11, a through hole 12 formed on a central shaft of the body 11, at least four damping holes 13 formed on the body 11, and two damping grooves 14 formed on the body 11.
The shock-absorbing member 20 is inserted into the shock-absorbing hole 13. Each of the shock-absorbing members 20 includes a member body 21 inserted into the shock-absorbing hole 13, a fixing block 22 provided on the member body 21, and an escape groove 23 provided at one end of the member body 21. The shock absorbing member 20 may be integrally formed.
The component body 21 is a cylindrical structure, one end of the component body 21 is flush with one end face of the body 11, the other end of the component body 21 is attached to the other end of the component body 21 of the damping component 20, the height of the component body 21 is half of the depth of the damping hole 13, so that one damping hole 13 can be provided with two damping components 20, and meanwhile, the damping components 20 do not extend out of the damping hole 13, so that the two end faces of the gear body 10 are still plane ends, and therefore gear rotation and installation are facilitated. The fixed block 22 is annularly arranged on the outer side wall of the element body 21, the fixed block 22 is located in the fixing groove 131, so that the damping element 20 can be clamped in the damping hole 13, the avoiding groove 23 is arranged on one end of the element body 21 and a terminal surface parallel and level of the body 11, the avoiding groove 23 is arc-shaped, and the avoiding groove 23 is used for avoiding and passing the damping ring 30 of the damping element 20.
The shock absorbing element 20 is made of an elastic material and is provided with a plurality of holes (not shown), and in particular, the shock absorbing element 20 is made of a heat conductive rubber. Since the shock absorbing member 20 is made of heat conductive rubber, so that the shock absorbing member 20 has elasticity, the shock absorbing member 20 can be inserted into the shock absorbing hole 13 by extrusion, and the fixing block 22 and the fixing groove 131 are engaged with each other, so that the shock absorbing member 20 is engaged with the shock absorbing hole 13, thereby fixing the shock absorbing member 20. And two shock-absorbing members 20 are provided for each shock-absorbing hole 13, so that the two shock-absorbing members 20 can be inserted from both ends of the shock-absorbing hole 13, respectively, for the convenience of mounting the shock-absorbing members 20.
