Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and thus the present invention is not limited to the specific embodiments of the present disclosure.
The concrete beneficial effects of embodiment 1 are that, install mounting ring 2 in first mounting groove 11 position, second mounting groove 21 seted up through mounting ring 2 position, second mounting groove 21 installation cylinder rotor 22 promptly, install mounting ring 2 to the first mounting groove 11 of shell body 1 afterwards, during operation insert support ring 3 in the second connect the via hole 23 of mounting ring 2, accomplish work promptly, it is easily installed, this bearing has adopted no inner circle design, the effectual bearing rolling element assembly space that has increased, the rolling element diameter has been increased, bearing load has been improved, this bearing has changed cylindrical roller bearing and has not had sealing member history, adopted sealing member design, can effectually seal bearing inner work space, improve the life of bearing
The specific beneficial effect of embodiment 2 is that in the conventional bearing design, the cylindrical roller bearing always appears in the aspects of large load, low rotating speed and no sealing. Because the load born by the cylindrical roller bearing is large, once foreign matters enter the bearing, the surfaces of the inner and outer ring raceways and the rolling body of the cylindrical roller bearing are rapidly damaged under the rolling of the large load, so that the early failure of the bearing is caused. In order to improve the internal environment of the cylindrical roller bearing, the cylindrical roller bearing is sealed, under the conditions that the bearing load is not changed and the internal space of the bearing is not occupied, the outer circle of the bearing is sealed, a sealing piece is arranged outside the bearing, the design can effectively protect the internal space of the bearing, the running environment of the bearing is improved, and the service life of the bearing is prolonged.
The working principle is as follows: installing the installation ring 2 in the first installation groove 11, installing the cylindrical rotor 22 through the second installation groove 21 opened in the installation ring 2, namely the second installation groove 21, and then installing the installation ring 2 in the first installation groove 11 of the outer shell 1, and inserting the support ring 3 into the second connecting through hole 23 of the installation ring 2 during operation, thus completing the operation, in the conventional design of the cylindrical roller bearing, in order to meet the requirement of the bearing for increasing load design, the bearing is required to use the maximized rolling elements, however, the four large bearing assemblies in the conventional bearing design limit the rolling element assembly space inside the bearing, and in the design of the cylindrical roller bearing, the conventional design concept is broken, the inner ring in the four large bearing assemblies is subtracted for product design, and the journal of the bearing installation part of the assembly shaft is used for replacing the action of the inner ring of the bearing, and the design method maximizes the rolling element assembly space inside the bearing, the diameter of the rolling body can be designed to the maximum extent, and the bearing capacity of the bearing is effectively improved.
The above description is only a preferred embodiment of the present invention, and not intended to limit the present invention in other forms, and any person skilled in the art may apply the above modifications or changes to the equivalent embodiments with equivalent changes, without departing from the technical spirit of the present invention, and any simple modification, equivalent change and change made to the above embodiments according to the technical spirit of the present invention still belong to the protection scope of the technical spirit of the present invention.
