In patent publication No. is in the patent documentation of CN1920327A; A kind of " polygonal star " motor pad has been proposed; Though can decay certain radially with the tangential vibrations energy, still there is following problem in this motor pad: there is randomness in the motor pad with contacting of motor construction bolt, and contact area is uncertain; The motor pad still belongs to line with the motor construction bolt and contacts in actual motion, effectiveness in vibration suppression is unstable.In addition, motor pad and motor construction bolt contact position rubber blanket flexibility are not enough, are unfavorable for the decay of the vibrational energy of radial vibration and tangential vibrations.
Summary of the invention
The present invention aims to provide a kind of new rubber damping pad; Can decay largely motor radial vibration, tangential vibrations energy; Solve electromagnetic noise; Adopt to increase motor construction bolt and the contact area of rubber damping pad and the flexibility of increase rubber blanket and motor construction bolt contact position rubber, make rubber be lined with the purpose that radial load, tangential force that more volume bears motor reach the damped vibration energy.Solve rubber damping pad of the prior art and contact with construction bolt and belong to line contact, contact area is little, and contact area is uncertain, and pliability causes the unfavorable technical problem of effectiveness in vibration suppression inadequately.
The present invention realizes that through following technical scheme a kind of rubber damping pad comprises: endoporus, and axis overlaps with the axis of rubber damping pad, extends axially along rubber damping pad, runs through rubber damping pad; Many groovings are opened on the sidewall of endoporus vertically, and arrange along circumferential each interval; Many raised lines form each raised line between many groovings, the surface towards the axis of each raised line is the cancave cambered surface that forms endoporus.
Further, the radial depth of grooving is greater than the width of grooving.
Further, the shape of cross section of grooving is a rectangle.
Further, the shape of cross section of grooving is an isosceles trapezoid.
Further, on the cross section of rubber damping pad, two relative grooving surfaces of each grooving are respectively cancave cambered surface.
Further, the quantity of raised line is more than 8.
Further, the quantity of raised line is 12.
Further, the quantity of raised line is 16.
Further, the profile of rubber damping pad is a cylinder.
Further, raised line and grooving axially run through said rubber damping pad.
Further, the axial middle part of the lateral surface of rubber damping pad has horizontal cannelure.
Through technique scheme, the contact area of rubber damping pad of the present invention and motor construction bolt increases; Improve positioning accuracy, avoided the randomness of contact area size; Increase endoporus rubber blanket flexibility, reduced the rubber blanket natural frequency, increased the isolation frequency scope, reduced the vibration transfer coefficient, improved vibration isolation efficiency.
Description of drawings
The accompanying drawing that constitutes a part of the present invention is used to provide further understanding of the present invention, and illustrative examples of the present invention and explanation thereof are used to explain the present invention, does not constitute improper qualification of the present invention.In the accompanying drawings:
Fig. 1 shows the vertical view of the rubber damping pad of one embodiment of the present of invention;
Fig. 2 shows the front section view of the rubber damping pad of one embodiment of the present of invention; And
Fig. 3 shows the front view of the rubber damping pad of one embodiment of the present of invention.
Embodiment
Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.Below with reference to accompanying drawing and combine embodiment to specify the present invention.
In conjunction with shown in Figure 1, the vertical view of a kind of rubber damping pad 1 of the present invention has been shown among the figure.Central axis place at rubber damping pad 1 is provided with endoporus 10, endoporus 10 be shaped as circular hole, this endoporus 10 extends axially along rubber damping pad 1, runs through said rubber damping pad 1.This endoporus 10 is set to be cooperated with the motor construction bolt in order to be suitable for when mounted.Rubber damping pad 1 also comprises many groovings 12, and these groovings 12 are opened on the sidewall of endoporus 10 vertically, and arranges along circumferential each interval.Form raised line 14 between grooving 12 and the grooving 12; Grooving 12 and raised line 14 be extending axially along rubber damping pad 1 all.The surface towards the axis of each raised line 14 is the cancave cambered surface that forms endoporus; The curved surfaces of each raised line 14 contacts with motor construction bolt in being installed in endoporus 10; Increase contact area with respect to rubber damping pad of the prior art, improved radially effectiveness in vibration suppression.Cutting out of grooving 12 increases rubber damping pad 1 and motor construction bolt contact position flexibility, reduces the natural frequency of rubber damping pad 1, improves the isolation frequency scope of vibrating isolation system, and then improves vibration isolating effect.Preferably, raised line 14 and grooving 12 axially run through rubber damping pad 1 all with endoporus 10.
