Abstract
The utility model discloses a cylindrical roller bearing solid retainer. Pocket holes are arranged on the retainer. A beam is arranged between two adjacent pocket holes. An inner locking point is arranged on each beam. Four corners of each pocket hole are smooth arc-shaped hollow cutter slots. Two side walls of each beam are flat planes. The side walls of the beams of the pocket holes are flat, and an arc slot is not arranged on an internally-guided self-locking position. Effective width of the beam width is increased, and the rigidity of the beams is good, so the support rack is not prone to fracture in the process of using. The four hollow cutter slots of the pocket holes are used as arc slot transition, so stress concentration can be effectively reduced, and service life of a bearing is prolonged.
Description
Technical field
The utility model relates to a kind of retainer, especially a kind of roller bearing internal lock point solid cage.
Background technique
High-Speed Cylindrical Roller Bearing in use exists fretting wear and sharp impacts between its retainer and roller and the lasso, and operating mode is poor.The structure of present this retainer is: retainer is provided with a plurality of tetragonal pockets hole; Four angles in pocket hole are wedge angle, and the beam in pocket hole is provided with the internal lock point, on the position of internal lock point, is milled with arc groove; This pocket hole adopts the broaching tool broaching to form, and its number is generally even number.Such retainer has certain disadvantages: at first, arc groove is arranged on the beam, like this will certainly attenuate deck-siding Effective face width, and cause its rigidity poor, cause the retainer fracture in the using process easily; Secondly, four jiaos of the pocket hole are easy to generate stress and concentrate, to forming hidden danger in working life of bearing.The in use easy motion unstability of this retainer, even fracture, and then cause bearing early failue.
Summary of the invention
The technical problem that the utility model will solve provides a kind of roller bearing solid cage of long service life.
For solving the problems of the technologies described above; The technological scheme that the utility model is taked is: a kind of roller bearing solid cage; On said retainer, being provided with the pocket hole, is beam between adjacent two pocket holes, on said beam, is provided with the internal lock point; Its key technology is: four angles in said pocket hole are level and smooth circular arc type clearance groov, and the two side of said beam is smooth face.
The number in said pocket hole is even number or odd number.
The hole of said pocket hole for forming via the machining center milling.
Adopt the beneficial effect that technique scheme produced to be: 1) sidewall of the utility model pocket hole beam is smooth; There has not been arc groove at interior guiding latching point (being the internal lock point) position; The Effective face width of its deck-siding increases, and rigidity is better, retainer easy-rupturing not in the using process; Four angles in pocket hole are the circular arc type clearance groov, and it is mild arc transition, and it is concentrated effectively to reduce stress, thereby can prolong the working life of bearing.
2) the machining center Milling Process is adopted in the pocket hole, and strange, even number can both be processed.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Wherein, 1, internal lock point; 2, pocket hole; 3, sidewall; 4, beam; 5, retainer; 6, clearance groov.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Referring to accompanying drawing 1; The utility model retainer 5 is provided with a plurality of pockets hole 2, is beam 4 between adjacent two pocket holes 2, on said beam 4, is provided with internal lock point 1; Four angular positions in said pocket hole 2 are level and smooth circular arc type clearance groov 6, and the two side 3 of said beam 4 is smooth face.
The processing route of the utility model is: car external diameter, surfacing → car internal diameter, other end → brill auxiliary hole → rough mill pocket hole → finish-milling moulding.
Wherein, Cutter Body Processing with Machining Center is adopted in the pocket hole 2 of the utility model, and so no matter odd number or even number can both machine shapings.Adopt the high precision dividing head calibration in the course of working; The deck-siding variation in pocket hole (being controlled at 0.1 ㎜), the high variation in the end (0.02 ㎜), fenestra sidewall are more accurate to variation (0.02 ㎜) the equidimension control of benchmark; Precision is higher, and the degree of symmetry in pocket hole 2 can be controlled in 0.05 ㎜.
After four clearance groovs 6 in pocket hole 2 adopt arc groove, can know that through finite element analysis its maximum stress is reduced to 226Mpa by original 416MPa, effectively reduce stress and concentrated.
Claims (3)
1. roller bearing solid cage; On said retainer (5), be provided with pocket hole (2); Between adjacent two pocket holes (2) beam (4); On said beam (4), be provided with internal lock point (1), it is characterized in that: four angles in said pocket hole (2) are level and smooth circular arc type clearance groov (6), and the two side (3) of said beam (4) is smooth face.
2. a kind of roller bearing solid cage according to claim 1 is characterized in that: the number in said pocket hole (2) is even number or odd number.
