Abstract
The invention provides a supporting bearing for a drawing shaft of a spinning machine, which comprises a bearing seat, an outer ring, an inner ring, needle rollers, steel balls, a steel ball retainer, a needle roller retainer and shield rings. The surface of the outer ring is provided with a circular-arc raceway and a straight raceway. The surface of the inner ring is provided with a circular-arc raceway and a straight raceway corresponding to those of the outer ring. A group of steel balls are arranged at the centers of the circular-arc raceways of the inner and outer rings and the steel balls separated at along the circumstantial direction by the steel ball retainer. A group of needle rollers are arranged at the centers of the straight raceways of the inner and outer rings and the needle rollers are separated by the needle roller retainer. Two shield rings which limit the needle rollers and the needle roller retainer to deflect axially are arranged at both sides of the straight raceways. The invention is designed of a set of combination bearing instead of two sets of bearings in the prior art, which avoids early invalidation during operation resulted from differences in different bearings. The invention meets the use requirements of high load for the bearing and simultaneously improves the lubrication of the bearing.
Description
One, technical field
The present invention relates to a kind of block bearing of fine spining machine drawing-off axle, be mainly used in the supporting of the drawing-off in the fine spining machine headstock in the Weaving device.
Two, background technology
Bearing mounting structure on the existing Weaving device as shown in Figure 1, the configuration of bearing is made up of two cover deep groove ball bearings 2, separates with lining 3 at the inner ring place of bearing.Two cover bearings are installed in the bearing block 1, and carry out axial location and carry axial force with back-up ring 4.Oilhole 5 is arranged on the bearing block, and repairing is by oilhole 5 lubricating grease to be squeezed in the space 6 during maintaining, enters in the bearing again.
Existing bearing is configured under the operating mode of general light load and can meets the demands, but along with the number of spindles of fine spining machine strengthens, the machine lengthening, under the situation that the load of bearing obviously strengthens, the not competent work of bearing shows as the bearing beginning of fatigue failure.Its reason is:
1, bearing has born very large radial and axial combined loading at work, because textile industry, bearing is to work uninterruptedly, has caused the fatigue damage on bearing working surface and has caused bearing failure.
2, bearing is a grease lubrication, lubricating grease is to enter two cavitys 6 that overlap between the bearings by the oilhole on the bearing block 15, just can enter on the working surface of bearing then, like this for the working surface that makes bearing has enough lubricating grease, just must at first after filling up lubricating grease in the cavity 6, lubricating grease be entered in the bearing.Because in the bearing block 1 full lubricating grease is arranged, lubricating grease is driven stirring and can be produced very big heat at work, the effect that influence is lubricated, and be easy to produce lubricated stuffing situation not in place, make bearing failure.
3, owing to be the configuration of two cover bearings, therefore require the size of two cover bearings and the uniformity of beating very high, and this is difficult to accomplish under actual conditions.Bearing inconsistent makes bearing carrying inequality at work, also is the reason of bearing premature failure.
Three, summary of the invention
1, goal of the invention: in order to overcome the problems referred to above of prior art, the invention provides and a kind ofly can bear very big radial and axial power, lubricated convenient and reliable, and the drafting shaft support bearing of spinning machine of high conformity.
2, technical scheme: drafting shaft support bearing of spinning machine of the present invention, it comprises bearing block, outer ring, inner ring, needle roller, steel ball, ball retainer, cages for needle and back-up ring; The surface of outer ring is provided with a circular arc raceway and a linear raceway, inner peripheral surface is provided with a corresponding with it circular arc raceway and a linear raceway, one group of steel ball is arranged in the middle of the circular arc raceway of Internal and external cycle, and steel ball is separated at circumferencial direction by ball retainer; One group of needle roller is arranged in the middle of the linear raceway of inner and outer ring, and needle roller is separated by cages for needle; Be provided with two back-up rings of the axial dipole field of restriction needle roller and cages for needle in the both sides of linear raceway.
Sealing ring is equipped with in the both sides in the space between inside and outside circle, has oil groove and be attached thereto logical oilhole in the middle of the outer round surface of outer ring.
The present invention is the combination bearing of an integral body.Two row's rolling elements are arranged, and a row is made up of steel ball, and it is evenly separated by the ball retainer circumferencial direction, and steel ball is along the circular arc raceway work of the inside and outside lasso of bearing, and the axial force that bearing bears is mainly born by this row's rolling element, and bears the part radial load; Another row's rolling element is made up of needle roller, and it is evenly separated at circumferencial direction by cages for needle, and needle roller is along the linear raceway work of the inside and outside lasso of bearing, and the radial load that bearing bears is mainly born by this row's rolling element.
3, beneficial effect: the present invention is designed to a cover combination bearing to the installation configuration of existing two cover bearings, has avoided because the initial failure in the bearing working that the difference between the different bearings causes; Adopt the design that ball bearing bears axial force and needle bearing comes bearing radial force, utilized their work characteristics to satisfy the instructions for use of bearing well; Because whole design bearing also makes the lubricated of bearing be improved, the work raceway that lubricating grease can directly enter bearing by the oil groove and the oilhole of outer ring.
Four, description of drawings
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is the structural representation of invention.
Five, the specific embodiment
Drafting shaft support bearing of spinning machine as shown in Figure 2 comprises bearing block 1, outer ring 7, inner ring 8, needle roller 9, steel ball 10, ball retainer 11, cages for needle 12, back-up ring 13, sealing ring 14, oil groove 5 and oilhole 15.
The inner surface of bearing outer ring 7 is provided with two work raceways, and one is the circular arc raceway, and another is the linear raceway, and corresponding bearing cone 8 outer surfaces also have two raceways, and one is the circular arc raceway, and another is the linear raceway.Arrange one group of steel ball 10 in the middle of the circular arc raceway of inside and outside lasso, steel ball is evenly separated at circumferencial direction by ball retainer 11; Arrange one group of needle roller 9 in the middle of the linear raceway of inside and outside lasso, needle roller is separated equably by cages for needle 12, is provided with two back-up rings 13 in the both sides of the linear raceway of outer ring, in order to the axial dipole field of restriction needle roller and cages for needle.Near the endoporus both sides on plane seal groove is arranged at bearing outer ring, a slice sealing ring 14 respectively is installed in seal groove, sealing ring 14 plays the lubricating grease that prevents bearing inside and leaks and prevent the effect that outside dust or titbit enter bearing inside.Also be provided with oil groove 5 and oilhole 15 at bearing outer ring 7, can directly dose lubricating grease on the work raceway of bearing by oil groove 5 and oilhole 15.
