Specific embodiment
With reference to the accompanying drawings and examples, the specific embodiment of the present invention is described in further detail.Hereinafter implement Example can not be used for limiting the scope of the present invention for illustrating the present invention.
The structure of the double-deck ditch super abrasive high speed laundry machine bearing of the embodiment of the present invention includes as shown in Figures 1 to 4：Outside one 1, one inner ring 2 of circle, the adjustment of a some rolling elements 3 and circle 4.
The inner peripheral surface of the outer ring 1 is provided with external groove 5, and the outer circumference surface of inner ring 2 is provided with inner groovy 6, and some rolling elements 3 are embedding Between external groove 5 and inner groovy 6, and each rolling element 3 is contacted with being between external groove 5 and between inner groovy 6, i.e., should Contact between rolling element 3 and external groove 5 is two-point contact, forms one layer of groove, connecing between the rolling element 3 and inner groovy 6 It is also two-point contact to touch, and forms another layer of groove, due to having abandoned the contact of line face, using four point contacts friction can be reduced, because Produced heat can reduce during this bearing high-speed cruising, rotate at a high speed beneficial to long-time.
Further, adjustment circle 4 is socketed on the excircle of outer ring 1, is provided with for adjusting between adjustment circle 4 and outer ring 1 The adjustment mechanism of both axialities whole, the adjustment mechanism includes some adjusting screws 7, and the excircle annular of adjustment circle 4 uniformly sets Be equipped with some adjusting holes of some adjusting screws 7 of correspondence, adjusting screw 7 screw in after corresponding adjusting hole with the excircle of outer ring 1 Abut, by screwing or unscrewing adjusting screw 7, you can adjustment adjustment circle 4 and the axiality of outer ring 1, with guarantee adjustment circle 4 with it is outer The axiality of circle 1 realizes the axiality controllable between bearing block and bearing, Jin Erfang in a rational margin of tolerance Easily occur to swing and affect bearing when only due to the axiality between bearing block and bearing, easy-regulating does not cause bearing to run up Service life.
In the present embodiment, machine bearing of doing washing also includes two fixed plates 8, and two fixed plates 8 are individually fixed in adjustment The both sides of 4 axial directions are enclosed, and is brought into close contact with the both sides of the axial direction of outer ring 1.Specifically, the outward flange of two fixed plates 8 passes through respectively Holding screw 9 is fixed on the both sides of 4 axial directions of adjustment circle, and inward flange is brought into close contact with the both sides of the axial direction of outer ring 1.So, the He of outer ring 1 Adjustment circle 4 is by the dual fixation of fixed plate of both sides, it is ensured that the stability that bearing rotates at a high speed.
The excircle of adjustment circle 4 is socketed with the shock absorbing ring 10 for shock-absorbing damping, and the shock absorbing ring 10 includes what is be coaxially disposed First shock ring 11, the middle shock ring 13 of shock ring 12 and second, the first shock ring 11, the second shock ring 13 are located at respectively centre The both sides of shock ring 12, are provided with the toroidal cavity 14 for playing cushioning effect in the first shock ring 11, the second shock ring 13, Middle shock ring 12 is the resilient solid torus of tool, the shock ring 11 of middle shock ring 12 and first, the connection of the second shock ring 13 Place is provided with arc groove 15, and middle shock ring 12 is connected knot with the first shock ring 11, the second shock ring 13 for integral type Structure, monolithic construction is beneficial to raising shock-absorbing damping effect.Here, the first shock ring 11, the annular radius phase of the second shock ring 13 Deng and be all higher than the annular radius of middle shock ring 12 so that shock absorbing ring 10 is formed as structure low between the senior middle school of two ends, works as bearing During primary vibrations, only cushioning effect is played by the first shock ring 11, the second shock ring 13, when bearing is in senior vibrations When, by the first shock ring 11, the common performance cushioning effect of 12 and second shock ring of middle shock ring 13, can effectively reduce bearing Vibrations under high speed rotation status.
As described above, the indent in the laundry machine bearing of the present invention between the external groove of each rolling element and outer ring and with inner ring A contact is between groove, friction point is reduced, and then guarantees that the bearing frictional heat produced in high-speed cruising is relatively low, and Adjustment snare is socketed with bearing top circle week, by governor motion both axialities adjustable, to prevent bearing from transporting at a high speed Swing during row, therefore the life-span of the laundry machine bearing of the present invention is high, can be applied to and rotate at a high speed.
The above is only the preferred embodiment of the present invention, it is noted that for those skilled in the art come Say, on the premise of without departing from the technology of the present invention principle, some improvements and modifications can also be made, these improvements and modifications also should It is considered as protection scope of the present invention.
