Description
[technical field]
The present invention relates to technical field of bearings, specifically the present invention relates to the cylindrical roller bearing pressing cage of a kind of energy self-locking.
[background technique]
Known, general cylindrical roller bearing adopts B-mode pressing cage, as depicted in figs. 1 and 2, described B-mode pressing cage arranges inside or outside lock claw 11 respectively in the both sides of fenestra, this kind of retainer is in the processing and using process of reality, there is following shortcoming: 1, in order to solve the breach problem of lock claw 11, technique requires annealing operation; 2, because the width of fenestra is generally more than two thicknesss of slab larger than roller diameter, the quantity of roller is so just decreased to a certain extent; 3, need fit drawing die during assembling, add assembling mould and equipment; 4, retainer does not have the function of self-locking roller; 5, greatly, during work, noise is large for roller and retainer area of contact; Therefore, provide a kind of and self-locking and the retainer that can solve the roller bearing of lock claw breach can become the basic demand of those skilled in the art.
[summary of the invention]
In order to overcome the deficiency in background technique, the invention discloses the cylindrical roller bearing pressing cage of a kind of energy self-locking, pinning roller by arranging salient point, dropping to limit roller, achieving roller self-locking and all spendable object of the bearing of outer ring or inner wrap strip rib.
For achieving the above object, the present invention adopts following technological scheme:
The cylindrical roller bearing pressing cage of a kind of energy self-locking, comprise rib, lower gear limit and multiple Kong Liang, described multiple holes distance between girders is arranged between rib and lower gear limit uniformly, fenestra is equipped with between every two Kong Liang, roller is equipped with in each fenestra, the upper-end surface of described upper rib is provided with the concave edge extended internally, the outward flange of along the circumferential direction extension is provided with in the lower end surface on lower gear limit, be provided with at the middle part of Kong Liang and cave inward or the terraced steps on band slope of outwardly convex, be equipped with salient point at the middle part of fenestra lower end.
The cylindrical roller bearing pressing cage of described energy self-locking, in the middle part of Kong Liang, setting caves inward and is with the retainer of the terraced steps on slope, is applied to the bearing of outer ring being provided with raised edge.
The cylindrical roller bearing pressing cage of described energy self-locking, arranges outwardly convex and the retainer of the terraced steps on band slope, is applied to the bearing of inner wrap strip rib in the middle part of Kong Liang.
The cylindrical roller bearing pressing cage of described energy self-locking, the lower end surface of roller is provided with inside depression, and the salient point arranged in the middle part of each fenestra lower end is arranged in the depression of roller lower end.
Owing to have employed technique scheme, the present invention has following superiority:
1, salient point 4 is equipped with at the middle part of fenestra 5 lower end, by salient point 4, roller 6 is pinned, roller 6 and retainer is made to form assembly separately and not come off, and make Kong Liang and roller have good surface of contact, not only saving traditional B-mode retainer is the annealing operation solving curved pawl breach problem and take in technique, and eliminate curved pawl assembling mould and equipment, the surface of contact of roller and retainer can also be reduced, reduce the Rotation Noise of bearing in operation process.
2, the present invention is applied to the cylindrical roller bearing pressing cage of two kinds of different structures, and in the middle part of hole beam 7, setting caves inward and is with the retainer of the terraced steps on slope, is applied to the bearing of outer ring being provided with raised edge; Outwardly convex is set in the middle part of hole beam 7 and the retainer of the terraced steps on band slope, is applied to the bearing of inner wrap strip rib; .
3, the present invention is owing to eliminating curved pawl, and make the retainer of same size when ensureing hole beam strength, can increase fenestra number, the bearing accordingly with size can increase roller number, thus adds the bearing capacity of bearing.
4, the present invention is by being provided with the concave edge 2 extended internally in the upper-end surface of upper rib 1, is provided with the outward flange 10 of along the circumferential direction extension in the lower end surface on lower gear limit 8, makes the rigidity of retainer support body higher.

[embodiment]
Can explain the present invention in more detail by the following examples, the present invention is not limited to the following examples;
The cylindrical roller bearing pressing cage of the energy self-locking by reference to the accompanying drawings described in 2-3, comprise rib 1, lower gear limit 8 and multiple holes beam 7, beam 7 interval, described multiple holes is arranged between rib 1 and lower gear limit 8 uniformly, fenestra 5 is equipped with between every two hole beams 7, roller 6 is equipped with in each fenestra 5, the upper-end surface of described upper rib 1 is provided with the concave edge 2 extended internally, the outward flange 10 of along the circumferential direction extension is provided with in the lower end surface on lower gear limit 8, be provided with at the middle part of hole beam 7 and cave inward or the terraced steps on band slope of outwardly convex, salient point 4 is equipped with at the middle part of fenestra 5 lower end.
The cylindrical roller bearing pressing cage of described energy self-locking, in the middle part of hole beam 7, setting caves inward and is with the retainer of the terraced steps on slope, is applied to the bearing of outer ring being provided with raised edge.
The cylindrical roller bearing pressing cage of described energy self-locking, arranges outwardly convex and the retainer of the terraced steps on band slope, is applied to the bearing of inner wrap strip rib in the middle part of hole beam 7.
