Abstract
The utility model provides a kind of self-aligning roller bearing inner ring ball-loading hole structure, it is therefore an objective to eliminates raceway and collides with and injures solution assembly problem.Take particular technique measure as follows：(1) the ball-loading hole of bearing inner race is adjusted to α angles with the angle of inner ring (4) axis by 0 degree；α angles are at 5 degree~15 degree.The beneficial effects of the utility model are：Raceway bump injury disappears, and improves efficiency of assembling.
Description
Technical field
The utility model is related to the inner ring structure of self-aligning roller bearing, more particularly to a kind of self-aligning roller bearing inner ring dress ball
Mouth structure.
Background technology
As shown in figure 1, existing self-aligning roller bearing ball-loading hole is (1) with bearing inner race, (4) axis is in 0 degree of angle, in assembling
During the inclination (2) of influence rolling element, causing rolling element, (2) chamfering is contacted with roller surface in advance, now rolling element (2) axis with
The angle of Race Line formation is excessive, adds limitation of the retainer (3) to rolling element, hinders the smooth entrance of rolling element (2).Due to
(3) retainer has certain elasticity, and rolling element can be pushed into specified location by this moment only increasing thrust, be rolled in the process
(2) (4) cut occurs in raceway contact point to body with inner ring, and the thrust that rolling element is subject to is bigger, and cut can be heavier, occurs when serious
Bump injury, serious influence is caused to bearing quality, reduces the service life of bearing.
The content of the invention
The utility model provides a kind of self-aligning roller bearing inner ring ball-loading hole structure, it is therefore an objective to eliminates raceway and collides with and injures solution
Certainly assembly problem.Take particular technique measure as follows：
(1) the ball-loading hole of bearing inner race is adjusted to α angles with the angle of inner ring (4) axis by 0 degree, in the elevation angle；α angles exist
5 degree~15 degree.
This is using new beneficial effect：Raceway bump injury disappears, and improves efficiency of assembling.
Brief description of the drawings
Fig. 1 is existing self-aligning roller bearing ball-loading hole；
Fig. 2 is the self-aligning roller bearing ball-loading hole after improving.
Marked in figure：Ball-loading hole 1, rolling element 2, retainer 3, inner ring 4.
Embodiment
The utility model is further illustrated in conjunction with the accompanying drawings and embodiments.
As shown in Fig. 2 being adjusted to the ball-loading hole 1 of bearing inner race, by the angle of ball-loading hole 1 and the axis of inner ring 4 by 0
Degree is adjusted to α angles, in the elevation angle, at 5 degree~15 degree；Because the angle of ball-loading hole 1 is in the elevation angle, inclining upwards when rolling element 2 is assembled
Gradient is added, and the chamfering of rolling element 2 is contacted reduction with roller surface, and assembling rolling element is more flexible, by the way enter specific bit
Put.
Claims (2)
1. a kind of self-aligning roller bearing inner ring ball-loading hole structure, it is characterised in that：The ball-loading hole of the bearing inner race (1) with inner ring
(4) the angle of axis is adjusted to α angles by 0 degree, in the elevation angle.
2. according to a kind of self-aligning roller bearing inner ring ball-loading hole structure described in claim 1, it is characterised in that：The α angles are 5
~15 degree of degree.
