Abstract

The utility model discloses a precise heavy load idler wheel bearing which comprises an outer ring, inner rings and a plurality of steel balls. The inner surface of the outer ring is provided with a rolling body circular arc face. The inner rings comprise a first inner ring and a second inner ring. A first rolling body semi-circle arc face is arranged on the first inner ring, and a second rolling body semi-circle arc face is arranged on the second inner ring. A rolling body passageway is formed by enclosing of the rolling body circular arc face of the outer ring, the first rolling body semi-circle arc face and the second rolling body semi-circle arc face and is filled with the steel balls side by side. By adoption of the structure, filled with the steel balls, the bearing enables a retainer to be removed so that overall bearing capacity of the bearing is improved, and the bearing is strong in axial bearing capacity due to being in three-point contacting type so that axial swing of the bearing is reduced, and therefore the bearing is enabled to be stable in operation, and service life of the bearing is prolonged.

Description

Precise heavy-load roller bearing
Technical field
The utility model relates to a kind of bearing, relates in particular to a kind of for mechanically operated roller bearing.
Background technique
Bearing is often used in machine driven system, deep groove ball bearing is exactly wherein the most frequently used a kind of, common common deep groove ball bearing on the market, comprise outer ring, inner ring, retainer and steel ball, the basic role of retainer in deep groove ball bearing is that steel ball itself is maintained, it is larger that but retainer itself takes up room, make the steel ball number in the deep groove ball bearing less, the bearing capacity of deep groove ball bearing is limited, the ability of bearing thrust load a little less than, in the machine driven system that has, can not satisfy usage requirement.
The model utility content
The utility model provides the bearing of a kind of full spherical structure, 3 contact-types for deficiency of the prior art.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Precise heavy-load roller bearing, comprise outer ring, inner ring and several steel balls, described inner surface is provided with the rolling element arc surface, described inner ring comprises the first inner ring and the second inner ring, described the first inner ring is provided with the first rolling element semicircle cambered surface, described the second inner ring is provided with the second rolling element semicircle cambered surface, and described rolling element arc surface, the first rolling element semicircle cambered surface and the second rolling element semicircle cambered surface surround a rolling element passage, and row have been expired steel ball in the described rolling element passage.
According to the technical solution of the utility model, described rolling element arc surface, the rolling element passage that the first rolling element semicircle cambered surface and the second rolling element semicircle cambered surface surround has formed the structure of a full ball, compared with common deep groove ball bearing, removed retainer, increased steel ball number, the overall bearing capacity of bearing is increased, described rolling element arc surface, the first rolling element semicircle cambered surface contacts in three directions with steel ball with the second rolling element semicircle cambered surface, form 3 contact type structures, 3 contact type structures make bearing when bearing thrust load, thrust load makes the surface of contact Directional Decomposition partial load of steel ball and the first arc surface and the second arc surface, improved the ability that bearing bears thrust load, 3 contacts are compared with common deep groove ball bearing, axial capacity that three-point-contact bearing bears is strong, reduce the axial runout of bearing, made bearing operation steady, improved bearing life.
As further improvement of the utility model, described the first inner ring middle part convexes with annulus, and described the second inner ring middle part is provided with through hole, described annulus snaps in the described through hole, make the first inner ring and the second inner ring combination by snapping in mode, form an integral inner ring, structurally more reasonable.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As shown in the figure, be a kind of embodiment of the utility model, a kind of precise heavy-load roller bearing, comprise outer ring 1, inner ring and several steel balls 4, described outer ring 1 outer surface is provided with groove, and groove is used for belt or other mechanical transmission components that the loading machine transmission is used, inner surface is provided with rolling element arc surface 11, rolling element arc surface 11 inwardly concaves, and recessed face is circular shape, matches with steel ball.Described inner ring comprises the first inner ring 2 and the second inner ring 3, described the first inner ring 2 is provided with the first rolling element semicircle cambered surface 21, the first rolling element semi-circle is recessed towards the central direction of the first inner ring, recessed radian cooperates with steel ball, described the second inner ring 3 is provided with the second rolling element semicircle cambered surface 31, described the second rolling element semi-circle is recessed towards the central direction of the second inner ring, recessed radian cooperates with steel ball, described rolling element arc surface 11, the first rolling element semicircle cambered surface 21 and the second rolling element semicircle cambered surface 31 surround a rolling element passage, and the steel ball row have been expired whole rolling element passage.
Mechanical transmission component has driven the rotation of precise heavy-load roller bearing, in the process of rotating, bearing need to bear thrust load, thrust load is in the process of effect, contact because steel ball cooperates in three directions with rolling element arc surface, the first rolling element semicircle cambered surface and the second rolling element semicircle cambered surface, formed 3 contact type structures.Thrust load is decomposed load to the first rolling element semicircle cambered surface and the second rolling element semicircle cambered surface, thrust load is decomposed in the process of effect, improved the ability that bearing bears thrust load, 3 contacts are compared with common deep groove ball bearing, because thrust load decomposes, it is strong to make it bear axial capacity, has reduced the axial runout of bearing, make bearing operation steady, improved bearing life.
Row have been expired steel ball in the rolling element passage, and when inner ring split out from the outer ring, steel ball formed a circular shape by the mode that is close on the rolling element arc surface, and steel ball can not split away off separately.Like this, steel ball does not need retainer just can maintain, and the quantity of steel ball increases to some extent compared with deep groove ball bearing, there is not retainer between steel ball and the steel ball, removed the space that retainer takies, increased the quantity of steel ball, the increase of quantity increases the overall bearing capacity of bearing.
The first inner ring middle part convexes with annulus 22, and described the second inner ring middle part is provided with through hole 32, and described annulus snaps in the described through hole, by snapping in mode the first inner ring and the second inner ring are closely cooperated, in conjunction with complete, the structure that forms a whole, structurally more reasonable.
