Description
Technical field:
This utility model relates to a kind of easy-to-assemble low antifriction roller bearings.
Background technology:
Roller bearing is the rolling bearing making rolling element with short cylindrical, circular cone or drum-shaped roller, is widely used in multiple
Mechanically.Existing roller bearing is to be arranged between the inner ring of bearing and outer ring by roller by retainer mostly, prevents
Roller offsets when rotating.But existing roller bearing is in order to reduce friction, improve the stability that bearing is overall, assemble
Get up relatively time-consuming, and be difficult to dismantle, affect production efficiency.And it is many between roller and the mounting groove of existing roller bearing
Contacting for face, friction during roller rolls and between mounting groove is very big, there will be heating and the situation of abrasion after long-time rotation,
Affect the service life of roller bearing.
Summary of the invention:
The purpose of this utility model is to solve the problems of the prior art, it is provided that a kind of simple in construction, interior during use
Portion's friction is little, and is easy to connect fixing easy-to-assemble low antifriction roller bearings.
In order to achieve the above object, the technical solution of the utility model is:
A kind of easy-to-assemble low antifriction roller bearings, including bearing base, described bearing base is provided with connecting portion, institute
State socket on connecting portion and retainer is installed, described bearing base offers mounting groove, in described mounting groove around connecting portion
Being provided with roller by retainer, described roller is provided with hemispheric projection, described rolling away from the center of retainer side
Son is connected by protruding and in mounting groove supporting walls support；Bearing cover, described bearing cap are installed on described bearing base
Offering on plate with roller side is the supporting part of linear contact lay.
Being provided with gripper shoe on described bearing cover, described gripper shoe offers cannelure on one end of connecting portion,
Self-lubricating plate is installed on described cannelure.
Described projection is integrated with roller and is fabricated by.
Offering oil filler point on described bearing cover, the outlet of described oil filler point is opened on supporting part.
Fixed card slot is offered on the side of described bearing cover.
Offering groove on described bearing base, in described groove, activity clamping is provided with connector, opening of described groove
Plug is installed at Kou.
The beneficial effects of the utility model are: the easy-to-assemble low antifriction roller bearings of one of the present utility model, roller is remote
Being provided with hemispheric projection from the center of retainer side, roller supports phase by protruding with the supporting walls in mounting groove
Even, it is achieved that roller and the point cantact of supporting walls, the friction between roller and supporting walls is effectively reduced；Offer on bearing base
Fluted, in described groove, activity clamping is provided with connector, bearing base can be made to have multiple connection by connector solid
Determining mode, the opening part of described groove is provided with plug, can be fixed in groove by plug when connector does not uses
In, very convenient.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
