Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention aims to provide a rolling bearing, which solves the problems in the prior art and has a good sealing effect.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
The invention provides a rolling bearing, as shown in figures 1-3, which comprises a bearing outer ring 1, a bearing inner ring 4, a plurality of balls, a retainer and two sealing rings 3, wherein the bearing inner ring 4 is coaxially sleeved in the bearing outer ring 1, the balls are uniformly arranged between the bearing outer ring 1 and the bearing inner ring 4, the retainer is fixedly arranged between the bearing outer ring 1 and the bearing inner ring 4, and the retainer is used for isolating each adjacent ball;
the inner wall of the bearing outer ring 1 is provided with two circumferential first annular grooves 2, the two first annular grooves 2 are respectively arranged between a ball groove 6 on the bearing outer ring 1 and two end faces of the bearing outer ring 1, the outer wall of the bearing inner ring 4 is provided with two circumferential second annular grooves 7, the two first annular grooves 2 correspond to one second annular groove 7, a sealing ring 3 is arranged between the corresponding first annular groove 2 and the corresponding second annular groove 7, the first annular groove 2 and the second annular groove 7 can play a role of fixing the sealing ring 3, each sealing ring 3 is in interference fit with the first annular groove 2 and the second annular groove 7, and on the premise of not influencing the rotation of the bearing inner ring 4, each sealing ring 3 can well block dust impurities outside the sealing ring 3 in interference fit with the first annular groove 2 and the second annular groove 7, therefore, the rolling bearing provided by the invention has a good sealing effect.
Furthermore, each first annular groove 2 and each second annular groove 7 are arc-shaped grooves, the cross section of the sealing ring 3 is circular, and when the sealing ring 3 is installed in a cavity between the first annular groove 2 and the second annular groove 7, the sealing ring 3 can roll between the first annular groove 2 and the second annular groove 7 by adopting the cylindrical sealing ring 3, so that the installation is simple and convenient.
Furthermore, the sealing ring 3 is a rubber ring, which has low cost, good friction resistance and long service life.
Furthermore, a plurality of threaded holes 5 are uniformly formed in the end face of the bearing outer ring 1 in the circumferential direction, a bolt 8 is installed in each threaded hole 5, the bolt 8 is used for fixing the bearing on a fixing seat, the fixing seat can be an end cover of a motor, the conventional bearing fixing mode is that the bolt is clamped and fixed in a bearing seat, however, the space for installing the bearing seat does not exist in the working environment of part of the bearing due to the problems of small bearing operation space and the like, and particularly in the technical field of special bearings for electric forklift driving systems, therefore, the bearing can be fixed on the fixing seat without arranging the bearing seat after the threaded holes 5 are punched in the end face of the bearing outer ring 1, and the space for installing the bearing seat is saved.
