Description
Technical field
The utility model relates to a kind of rubber pad, particularly relates to a kind of rubber damping pad.
Background technique
In existing cabinet, machine fan motor mostly is vertical mounting type, rubber damping pad mostly is cylindrical body, in installation process, rubber pad is axially in compressive state, therefore decay to a certain degree can be had to the vibration of motor, but due to existing rubber pad and motor construction bolt area of contact little, in actual motion rubber pad and motor construction bolt and rubber pad mounting hole between be often in the state that single line contacts, rubber pad is very little to motor radial vibration, tangential vibrations decay.Because the root producing motor electromagnetic noise is motor radial vibration and tangential vibrations, existing rubber pad design can not fundamentally solve electromagnetic noise problem.
In order to overcome above-mentioned technical problem, existing prior art proposes one and has the rubber damping pad of " grooving ", certain radial direction and tangential vibrations energy although can decay, but the flexibility of the contact position of itself and motor is inadequate, cause effectiveness in vibration suppression unstable, be unfavorable for the decay of the vibrational energy of radial vibration and tangential vibrations.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of rubber damping pad of can significantly decay motor radial vibration, tangential vibrations energy.
For achieving the above object, the technological scheme that the utility model provides is:
A kind of rubber damping pad, the central axis place of this rubber cushion body is provided with circular inner hole, this endoporus runs through rubber cushion body, the inwall of this endoporus is provided with many groovings, these groovings are axially arranged on the sidewall of endoporus, and being circumferentially spaced arrangement, be provided with raised line between adjacent cutback, the surface towards medial axis of every bar raised line is the intrados forming endoporus; The end face and bottom surface of described rubber cushion body are provided with some locating slots, and rubber cushion body interior is also provided with antivibration layer, is provided with Damping material layer in this antivibration layer; The end face of described rubber cushion body and bottom surface are provided with some locating slots, and the spacing of locating slot is 60mm, and the radius of each locating slot is 40mm.
Horizontal circular groove is also provided with to the outer side surface at middle part in described rubber cushion body shaft.
Described grooving and raised line are respectively arranged with 16.
The both sides of described rubber cushion body are provided with corrosion resistant plate, and two pieces of corrosion resistant plates are parallel to each other, and the length of two pieces of corrosion resistant plates is less than the height of rubber cushion body.
the usefulness of technique scheme is:
1, basis is novel provides a kind of rubber damping pad, central axis place at rubber cushion body is provided with circular inner hole, the inwall of this endoporus is provided with many groovings, these groovings are axially arranged on the sidewall of endoporus, and be circumferentially spaced arrangement, be provided with raised line between adjacent cutback, the surface towards medial axis of every bar raised line is the intrados forming endoporus; The end face and bottom surface of described rubber cushion body are provided with some locating slots, and rubber cushion body interior is also provided with antivibration layer, is provided with Damping material layer in this antivibration layer; The end face of described rubber cushion body and bottom surface are provided with some locating slots, and the spacing of locating slot is 60mm, and the radius of each locating slot is 40mm; Compared to existing technology, add the area of contact with motor construction bolt, reduce the natural frequency of rubber pad, add isolation frequency scope, reduce vibration passing coefficient, vibration isolation efficiency improves 1.5 times compared to existing technology.
2, this novel provided a kind of rubber damping pad, is also provided with Damping material layer in it, can increases effectiveness in vibration suppression further.
3, this novel provided a kind of rubber damping pad, be also provided with corrosion resistant plate, and the spacing of locating slot is 60mm at the two ends of rubber cushion body, the radius of each locating slot is 40mm, not only can increase effectiveness in vibration suppression further, and the wearing and tearing of rubber cushion body can be reduced, improve working life.
Be further described originally novel below in conjunction with the drawings and specific embodiments.

Embodiment
embodiment 1
As Fig. 1, a kind of rubber damping pad shown in 2, comprise rubber cushion body 1, the central axis place of this rubber cushion body 1 is provided with endoporus 2, the shape of endoporus 2 is circular hole, this endoporus 2 runs through rubber cushion body 1, the inwall of this endoporus 2 is provided with many groovings 20, these groovings 20 are axially arranged on the sidewall of endoporus 2, and be circumferentially spaced arrangement, raised line 21 is provided with between adjacent cutback 20, the surface towards medial axis of every bar raised line 21 is the concave arc surface forming endoporus, the cambered surface surface of each raised line 21 contacts with the motor construction bolt be arranged in endoporus 2, radial vibration-reducing effect can be improved.Cutting out of grooving, can make rubber cushion body and motor construction bolt contact position flexibility increase, and reduces the natural frequency of rubber damping pad, improves the isolation frequency scope of vibrating isolation system, and then improves vibration isolating effect.
As shown in Figure 2,3, be also provided with horizontal circular groove 3 at the outer side surface at the axial middle part of described rubber cushion body 1, this circular groove 3 coordinates with the matching hole of extraneous mounting bracket when mounted.
