Abstract
A kind of extra large size bearing, comprise outer ring, inner ring, roller, retainer and check ring, described retainer is located between inner ring and outer ring, roller is evenly arranged in the pocket hole of described retainer, described check ring is arranged in the spring card slot on the outer peripheral surface of inner ring small end, check ring replaces the little rib of original structure, and described inner ring, roller, retainer and check ring form inseparable but dismountable inner assembly jointly; Described retainer is pressing cage.Roller designs is solid construction by this programme, can simplify roller heat treatment process; Change combination retainer into pressing cage, thus the number of parts of composition bearing is reduced, simplify bearing assemble technique, also reduce cost simultaneously; Eliminate the little rib on inner ring, and change check ring into, make structure become simple, improve the machining accuracy of inner ring.
Description
Technical field
The utility model relates to a kind of bearing, especially relates to a kind of extra large size bearing.
Background technique
In prior art, the structure of extra large size bearing as shown in Figure 1, the both sides of its inner ring 2 are respectively equipped with little rib 201 and large-flange 202, retainer is combination retainer, roller is set to hollow-core construction, retainer and roller are assembled by the pillar 7 be interspersed in hollow roller, and the back-up ring of the large end of roller is by being threaded on pillar, and the back-up ring of roller small end is welded on the weld 6 of pillar, in addition, the back-up ring of roller small end and the connection of pillar also can adopt the mode heating rivet weld.The inner ring structure that Fig. 2 adopts for Fig. 1.The shortcoming that this bearing exists is: inner ring processed complex, and the part of composition is many, processed complex, and assembly process is various, and cost is higher; Bearing in use pillar easily loosens, and causes bearing not work on, and extra large size bearing is most after using has the value of repairing and re-using, and after dismounting, back-up ring pillar can not use, and need supplement new parts, therefore costly.
Model utility content
The utility model mainly for solving above-mentioned Problems existing, providing a kind of extra large size bearing, combination retainer being changed into pressing cage, and eliminate the little rib of inner ring, change check ring into, make structure become simple, improve efficiency of assembling, also reduce cost simultaneously.
For solving above-mentioned Problems existing, the technological scheme that the utility model adopts is: a kind of extra large size bearing, comprise outer ring, inner ring, roller, retainer and check ring, described retainer is located between inner ring and outer ring, roller is evenly arranged in the pocket hole of described retainer, described check ring is arranged in the spring card slot on the outer peripheral surface of inner ring small end, check ring replaces the little rib of original structure, and described inner ring, roller, retainer and check ring form inseparable but dismountable inner assembly jointly; Described retainer is pressing cage.
Further, described check ring is provided with the first projection near the side of inner ring, the outer peripheral surface of described inner ring small end is provided with the age of a draught animal of establishing described first projection for card, check ring away from the side of inner ring be provided with for press roller to its play positioning action second protruding, described second protruding one end near roller has the plane of inclination of matching with described roller end face, and described inner ring, roller, retainer and check ring form inseparable but dismountable inner assembly jointly.
Further, described check ring is provided with otch, and the radial direction of described otch and check ring at an angle.
Further, the radial direction of described otch and check ring is 45° angle.
Further, described roller is solid construction.
The beneficial effect that the utility model brings is:
1, roller designs is solid construction by this programme, can simplify roller heat treatment process;
2, change combination retainer into pressing cage, thus the number of parts of composition bearing is reduced, simplify bearing assemble technique, also reduce cost simultaneously;
3, eliminate the little rib on inner ring, and change check ring into, make structure become simple, improve the machining accuracy of inner ring;
4, existing extra large size bearing, the roller of hollow is reinstalled after first pillar being loaded large back-up ring, then buckle little back-up ring to carry out welding rear riveted joint, bearing after improvement is easy to install, significantly improve efficiency of assembling, and the bearing after improvement is when damage parts changed by needs, after dismounting, other parts still can continue to use, and save expense.
