Abstract
The utility model discloses a transmission shaft bearing for rotor type open -end spinning machine reverses on case, including the bearing frame, set up minor axis in the bearing frame, cup joint the setting and be provided with the inner groovy in short epaxial outer bearing and inner bearing, the one end that the bearing frame inner wall is close to the inner bearing, the one end that the bearing frame inner wall is close to the outer bearing is provided with outer recess, the joint is provided with interior retaining ring in the inner groovy, the interior joint of outer recess is provided with outer retaining ring, be provided with the separation sleeve between inner bearing and the outer bearing. The utility model discloses novel structure, reasonable in design hold interior retaining ring setting through setting up at the inner bearing, guarantee when needing to be changed the bearing that it is more convenient to dismantle, avoids the damage of minor axis and outer bearing, and it is convenient to dismantle simultaneously, and labour saving and time saving improves work efficiency.
Description
Technical field
The utility model relates to a kind of bearing block, is specifically related to a kind of drive bearing block on rotor spinning machine reversing case.
Background technology
Existing bearing block on revolving cup frame reversing case, after wherein a certain double-row angular contact ball bearing damages, first outer back-up ring is pulled down during dismounting, again by inner bearing and outer bearing with minor axis outwards movement simultaneously, but because two bearings spacing is for being less than the single width of bearing, so when outer bearing shifts out bearing block not yet completely, inner bearing blocks by inner shield ring, cause the method dismounting of bearing Qiang.Its dismounting utilizes axle and the larger interference fit of bearing cone often, oppositely hit axle, utilize inner shield ring to control outer bearing outer ring, make its steel ball depart from retainer by force and be scattered, cause bearing enclose to be separated outer bearing is pulled down, and then inner shield ring and inner bearing are split out.This kind of dismounting mode wastes time and energy, and easily causes the damage of minor axis and outer bearing simultaneously.
Utility model content
For problems of the prior art, the purpose of this utility model is to design provides a kind of drive bearing block on rotor spinning machine reversing case.
Described a kind of drive bearing block on rotor spinning machine reversing case, comprise bearing block, the minor axis be arranged in bearing block, be socketed the outer bearing that is arranged on minor axis and inner bearing, it is characterized in that bearing block inwall is provided with inner groovy near one end of inner bearing, bearing block inwall is provided with outer groove near one end of outer bearing, in described inner groovy, clamping is provided with inner shield ring, in described outer groove, clamping is provided with outer back-up ring, is provided with separation sleeve between described inner bearing and outer bearing.
Described a kind of drive bearing block on rotor spinning machine reversing case, is characterized in that described separation sleeve comprises inner sleeve and the overcoat of socket setting.
Described a kind of drive bearing block on rotor spinning machine reversing case, is characterized in that leaving gap between described inner shield ring and the outer ring of inner bearing.
Described a kind of drive bearing block on rotor spinning machine reversing case, is characterized in that described gap is between 0.22-0.26mm.
The utility model novel structure, reasonable in design, by arranging, inner shield ring being arranged on inner bearing end, guaranteeing that, when bearing changed by needs, dismantle convenient, avoid the damage of minor axis and outer bearing, convenient disassembly, time saving and energy saving, increases work efficiency simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: 1-minor axis, 2-outer bearing, 3-inner bearing, 4-inner shield ring, the outer back-up ring of 5-, 6-inner sleeve, 7-overcoat.
Detailed description of the invention
The utility model is further illustrated below in conjunction with Figure of description.
As shown in Figure 1, a kind of drive bearing block on rotor spinning machine reversing case of the utility model, comprise bearing block, be arranged on the minor axis 1 in bearing block, be socketed the outer bearing 2 and inner bearing 3 that are arranged on minor axis 1, bearing block inwall is provided with inner groovy near one end of inner bearing 3, bearing block inwall is provided with outer groove near one end of outer bearing, in inner groovy, clamping is provided with inner shield ring 4, the gap of 0.22-0.26mm is left between the outer ring of inner shield ring 4 and inner bearing 3, in outer groove, clamping is provided with outer back-up ring 5, separation sleeve is provided with between inner bearing 3 and outer bearing 2, separation sleeve comprises inner sleeve 6 and the overcoat 7 of socket setting.
The inner groovy of the utility model by arranging, be convenient to snap in inner groovy by moving in inner shield ring 4, and between interior outer bearing, install inner sleeve 6 and overcoat 7 additional, for avoiding the temperature rise after operating, causing the trace of axle to extend and the additional stress that causes, leaving the expansion clearance of 0.25mm at inner shield ring 4 and the outer ring place of inner bearing 3, by this setting, once bearing damage, after being pulled down by outer back-up ring 5, outer bearing 2 and inner bearing 3 just can shift out smoothly along minor axis under the effect of minor axis 1 and inner-outer sleeve.Convenient disassembly, also can avoid the damage of minor axis and bearing.
Claims (4)
