Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, to help understanding content of the present utility model.
As shown in Figures 3 to 5, the utility model comprises fixing bucket 6 and lower bucket seat 3, in upper fixing bucket 6 and lower bucket seat 3 close positions, respectively on upper fixing bucket 6 and lower bucket seat be evenly provided with at least two grooves, the groove on upper fixing bucket 6 is corresponding with the groove on lower bucket seat 3.Upper fixing bucket 6 bottom is provided with wear-resisting ring 9, and rotating disc 2 upper end is provided with lower wear-resisting ring 8; With lower wear-resisting ring 8 tight contact therewith bottom upper wear-resisting ring 9, upper wear-resisting ring 9 and lower wear-resisting ring 8 all adopt the high-abrasive material that the hardness such as pottery or carbide alloy are high.Adopt the high-abrasive material that hardness is high, and by the Roughness Surface on Control of faying face below Ra0.5 micron, can ensure that wear-resisting ring 9 and lower wear-resisting ring 8 can abutting contact, form seamless cooperation, the chip that polished product in rotating disc is produced in polishing process and polishing medium can not enter between upper and lower wear-resisting ring, avoid mating surface wearing and tearing or stuck.Upper wear-resisting ring 9 is preferably different from the roughness in the face that contacts with each other of lower wear-resisting ring 8, to make both it between contact surface can not " adhesion ".
Wear-resisting ring preferably ceramic, compared with carbide alloy adopt ceramic material specific heat and thermal coefficient of expansion low, during operation, variations in temperature is little, and pressure increase between the two can not be caused due to thermal expansion because the coefficient of expansion is low, and the coefficient of friction between ceramic material is lower compared with alloy material, frictional force can be reduced further.
Fairlead 11 is interior step pipe, and interior step pipe top is provided with the annular raised step along its axis direction; Fore-set 12 is outer step cylinder, and outer step cylinder bottom side is provided with the annular raised step along its periphery; Fore-set 12 is inserted in fairlead 11, and fore-set 12 top stretches out in outside the annular raised step at fairlead 11 top, and the annular protrusion step of fore-set 12 bottom makes fore-set 12 be limited in fairlead 11 inner space; Bottom fore-set 12, be provided with spring 10 in fairlead 11, the snap ring 15 that the bottom of spring 10 is stuck in the draw-in groove of fairlead 11 inside bottom blocks; Upper fixing bucket 6 freely drops on lower bucket seat 3 by self gravitation, spring 10 can play the effect of decompression, make fixing bucket 6 and rotating disc 2 can abutting contact, upper fixing bucket 6 and the normal pressure of the junction of rotating disc 2 can be reduced again, make mutual frictional force minimally even not produce pressure.Between the bottom of spring 10 and snap ring 15, be also provided with pad 14, lower bucket seat 3 be provided with the bolt hole in the groove center of circle leading to from the bottom up and it is arranged, bolt 13 is through above-mentioned bolt hole and snap ring 15 and withstand on bottom pad 14.Fairlead 11 is inserted in groove that fixing bucket 6 and lower bucket seat 3 are arranged, and fore-set 12 top withstands on the bottom of the groove of setting on fixing bucket 6.Spring 10 is when just using, and elastic force is comparatively large, and the distance that bolt 13 can be put in groove is shorter; After spring 10 uses a period of time, elastic force reduces, bolt 13 can be put in distance in groove some, can ensure that spring 10 is applied to fixing bucket 6 and remains consistent with the elastic force of lower bucket seat 3 like this, and then make the upper wear-resisting ring 9 between fixing bucket 6 and rotating disc 2 and the complete abutting contact of lower wear-resisting ring 8 faying face, and the normal pressure reducing faying face does not even have normal pressure, reduce and even there is no frictional resistance.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
