Abstract
The utility model relates to a cylindrical roller bearing, and particularly relates to a cylindrical roller bearing capable of reducing axial friction force. The cylindrical roller bearing capable of reducing the axial friction force comprises an outer ring (1), an inner ring (5), an inner check ring (4), a cylindrical roller (2) and a retainer (3), wherein the inner sides of the flanges of the outer ring (1), the inner ring (5) and the inner check ring (4) of the cylindrical roller bearing are all provided with inclined surfaces; two end surfaces of the cylindrical roller (2) are both spherical surfaces; arc chamfers (9) are positioned between the two end surfaces of the cylindrical roller (2) and an excircle surface (6); and the intermediate parts of the two end surfaces of the cylindrical roller (2) are provided with recesses (8). The cylindrical roller bearing disclosed by the utility model has the characteristic of reducing the contact area of the cylindrical roller (2) and the flanges because the cylindrical roller (2) of the cylindrical roller bearing is in point contact with the flanges of the outer ring (1), the inner ring (5) and the inner check ring (4), thereby reducing the friction between the cylindrical roller (2) and the flanges and achieving the purposes of reducing the operation power consumption of the cylindrical roller bearing and prolonging the service life of the cylindrical roller bearing.
Description
Technical field
The utility model relates to a kind of roller bearing, relates in particular to a kind of roller bearing that reduces axial friction.
Background technique
Conventional roller bearing in using now includes outer ring, inner ring, inner shield ring, cylindrical roller and retainer; The inboard of outer ring rib, inner ring rib and inner shield ring rib is plane structure, and two end faces of cylindrical roller also are plane structure.In use, the cylindrical roller end face is large-area plane contact with outer ring rib, inner ring rib and contacting of inner shield ring rib, can produce more serious friction, causes the bearing operation power consumption big, the wearing and tearing of rib and roller end face are bigger, influence the working life of bearing.
The model utility content
The purpose of this utility model is to propose a kind of roller bearing that reduces axial friction.
The utility model is finished the technological scheme that its goal of the invention takes:
A kind of roller bearing that reduces axial friction, described roller bearing comprises
Outer ring, inner ring, inner shield ring, cylindrical roller and retainer are arranged; Rib inboard on described outer ring, inner ring and the inner shield ring is the inclined-plane; Two end faces of described cylindrical roller are sphere, are circular arc chamfering between two end faces of cylindrical roller and the outer round surface, and two end faces middle parts of cylindrical roller all have depression.
Characteristics of the present utility model are: the cylindrical roller of described roller bearing is a contact with outer ring rib, inner ring rib and contacting of inner shield ring rib, can reduce the area of contact of cylindrical roller and rib, thereby reduce the friction between them, reduce the wearing and tearing of rib and roller, reach and reduce the bearing operation power consumption, improve the bearing purpose in working life.
