Asymmetric combined sealed structure full complement cylindrical roller bearings

Abstract

A full-complement cylindrical roller bearing with an asymmetric combination type sealing structure comprises an outer ring, an inner ring, a rolling element and a sealing device, and is characterized in that the rolling element is arranged between the inner ring and the outer ring, the sealing device is arranged between the inner and outer rings on one side of the bearing and adopts a labyrinth sealing structure, the labyrinth sealing structure comprises an O-shaped sealing assembly and a movable check ring, an O-shaped rubber sealing ring is arranged on an O-shaped rubber sealing ring seat frame, and the movable check ring is arranged on one side of the O-shaped rubber sealing ring seat frame; a lip sealing assembly is further arranged between the inner and outer rings on the other side of the bearing. The inner ring and the outer ring adopts asymmetric design, the sealing structure adopts an asymmetric dual-sealing mode, the bearing start torque can be adjusted, when preload applied to the end surface is large, the bearing start torque becomes large, and a vehicle can meet requirements of various extreme terrain conditions; surfaces of the inner ring, the outer ring and the movable check ring of the bearing are subjected to colored galvanizing, and accordingly, the full-complement cylindrical roller bearing has very high corrosion resistance and oxidation resistance.

Description

technical field [0001] The invention relates to a wheel suspension system bearing for heavy-duty crawler or wheeled vehicles, in particular to a full complement cylindrical roller bearing with an asymmetric combined sealing structure, which belongs to the field of engineering machinery. Background technique [0002] In the wheel suspension system of heavy-duty tracked or wheeled vehicles, the bearings need high performance requirements such as high static load and corrosion resistance. If they do not meet the high performance requirements, they cannot meet the all-weather working requirements of the vehicle in various harsh climates. Contents of the invention [0003] In order to meet the all-weather working requirements of the bearings used in the vehicle suspension system in severe weather, the object of the present invention is to provide an asymmetric combined seal structure full complement cylindrical roller bearing. [0004] In order to achieve the above purpose, the...
