Abstract
The invention discloses a kind of motor self-aligning roller bearing, including inner ring, outer ring and the rolling element being arranged between inner ring and outer ring, described inner ring circumferentially has two annular grooves, and the cross section of described annular groove is concave, and described inner ring, the inner surface of outer ring are provided with oil lamella.The present invention, by injecting lubricating oil in annular groove, improves the lubricant effect of bearing and rotating shaft, reduces abrasion, extends the service life of bearing, is provided with oil lamella on inner ring, outer ring and rolling element simultaneously, improves its lubricant effect further.
Description
Technical field
The present invention relates to a kind of motor component, particularly relate to a kind of motor self-aligning roller bearing.
Background technology
Self-aligning roller bearing has two row symmetric form spherical rollers, and there is a shared sphere rolling outer ring
Road, inner ring has two raceways tilting an angle with bearing axis, has good aligning performance,
When the bending of axle stress or installation are concentric, bearing still can normally use, and regulation of mental activities is with bearing size
Series is different and different, and the regulation of mental activities angle typically allowed is 1～2.5 degree, bearing of the type bearing
Lotus ability is relatively big, and decapacitation is born radial load outer bearing and can also be born beidirectional and axially bear
Lotus, has preferable impact resistance, and the work that in general self-aligning roller bearing is allowed turns
Speed is relatively low.
The when that self-aligning roller bearing of the prior art being arranged on machine shaft, owing to being heat
Set is entered, and during using for a long time, generation is worn and torn by axle with bearing inner race, impact
The service life of bearing.
Summary of the invention
The present invention is in order to overcome deficiency of the prior art, it is provided that a kind of motor aligning roller axle
Hold.
The present invention is to be achieved through the following technical solutions:
A kind of motor self-aligning roller bearing, including inner ring, outer ring and be arranged on inner ring and outer ring
Between rolling element, described inner ring circumferentially has two annular grooves, and the cross section of described annular groove is recessed
Shape.
As the preferred technical solution of the present invention, the inner surface of described inner ring is provided with oil lamella.
As the preferred technical solution of the present invention, the inner surface of described outer ring is provided with oil lamella.
As the preferred technical solution of the present invention, the outer surface of described rolling element is provided with oil lamella.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is by annular groove
Inject lubricating oil, improve the lubricant effect of bearing and rotating shaft, reduce abrasion, extend making of bearing
With the life-span, on inner ring, outer ring and rolling element, it is provided with oil lamella simultaneously, improves its profit further
Sliding effect.

Fig. 1 is the front view of the present invention；
Fig. 2 is the A-A sectional view in Fig. 1；
Fig. 3 is the axonometric drawing of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings embodiments of the invention are elaborated: the present embodiment is with this
Implement under premised on bright technical scheme, give detailed embodiment and concrete operation
Process, but protection scope of the present invention is not limited to following embodiment.
Seeing Fig. 1, Fig. 2 and Fig. 3, Fig. 1 is the front view of the present invention, and Fig. 2 is in Fig. 1
A-A sectional view, Fig. 3 is the axonometric drawing of the present invention.
Described a kind of motor self-aligning roller bearing, including inner ring 1, outer ring 2 and in being arranged on
Rolling element 3 between circle 1 and outer ring 2, described inner ring 1 circumferentially has two annular grooves 4,
The cross section of described annular groove 4 is concave.
The inner surface of described inner ring 1 is provided with oil lamella, and the inner surface of described outer ring 2 is provided with oil film
Layer, the outer surface of described rolling element 3 is provided with oil lamella.
The present invention, by injecting lubricating oil in annular groove, improves the lubricant effect of bearing and rotating shaft,
Reduce abrasion, extend the service life of bearing, be provided with on inner ring, outer ring and rolling element simultaneously
Oil lamella, improves its lubricant effect further.
The ultimate principle of the present invention and principal character and the present invention excellent has more than been shown and described
Point.Skilled person will appreciate that of the industry, the present invention is not restricted to the described embodiments, on
State the principle that the present invention is simply described described in embodiment and description, without departing from the present invention
On the premise of spirit and scope, the present invention also has various changes and modifications, and these change and change
Enter to both fall within scope of the claimed invention.Claimed scope is by appended power
Profit claim and equivalent thereof define.
