Embodiment Construction

[0037] refer to figure 1 and figure 2 , the roller bearing 10 is provided with an assembly of roller bearing seals 12 each comprising a seal shell 14 and a rotor 16 forming a snap-fit ​​connection therebetween 18 which improves the handling of the roller bearing seal assembly 12 during its transport and assembly with other components of the roller bearing 10 . The snap connection 18 improves the handling of the assembly 12 of the roller bearing seal, since the rotor 16 is prevented from falling out of the seal casing 14 once the snap connection 18 has been formed by pressing the rotor 16 into the casing 14 . Furthermore, the snap connection 18 allows the rotor 16 to rotate relative to the can 14 so that the joined can 14 and rotor 16 can be easily mounted to the bearing cup 20 and the bearing cup 20 of the roller bearing 10 during assembly of the roller bearing 10 . Grinding ring 44. This is in contrast to prior methods which press the rotor out of the seal case insert to...

Abstract

In accordance with one aspect of the present disclosure, a roller bearing seal assembly is provided that includes a seal case and a rotor having a unitary, one-piece construction. The rotor is connected to the seal case and is rotatable relative to the seal case about an axis. The seal case and rotor include interfering portions that limit axial separation of the rotor and the seal case. In one embodiment, the rotor and seal case include at least one snap-fit connection that permits the rotor and seal case to be readily assembled. The at least one snap-fit connection includes the interfering portions which inhibit axial separation of the rotor and seal case after the rotor and seal case have been assembled.

Description

technical field [0001] The present disclosure relates to sealed railway roller bearings, and more particularly to components of assemblies of seals for railway roller bearings. Background technique [0002] A railcar has an assembly of chassis wheels that includes a frame, an assembly of one or more wheels, and roller bearings that connect the assembly of wheels to the frame. Each wheel assembly includes an axle and a wheel connected to the axle, with journals at opposite ends of the axle. Each roller bearing includes a first member mounted on the journal for rotation with the journal and a second member mounted on the frame. [0003] Railcars use various types of roller bearings. One type of roller bearing is a tapered roller bearing that includes one or more rows of tapered rollers. Tapered roller bearings and other types of bearings contain a lubricant within the bearing to reduce resistance to movement between the bearing's components. Bearings may also include seals...
