Abstract
The invention provides a novel spherical roller bearing. The novel spherical roller bearing comprises an outer ring (1), an inner ring (2), two rows of rollers (3) and two corresponding cages (4); and four locking points (6) are arranged in each pocket hole (5) of the cages (4). The novel spherical roller bearing has the advantages of improving the bearing capacity, reducing the friction resistance, accelerating the rotating speed and prolonging the service life.
Description
Technical field
The present invention relates to a kind of bearing, especially with regard to a kind of double row spherical roller bearing.
Background technology
With the raising of plant equipment machining accuracy, bearing capacity and rotating speed, the requirement in life-span to bearing are also increasingly
Height, traditional CA profile shafts are held and are limited by inner ring rib in its structure, and roller and increasing cannot be lengthened in the confined space of bearing
Addend amount.It is now to use CC type self-aligning roller bearing technologies to meet and improving the performance requirement of bearing more, be characterized in inner ring without
Rib, centre rib is replaced with sliding damper circle, and 2 steel plate punched retainers often are housed in set bearing, and in traditional design, retainer
It is use Intermediate Gray monolock points more, spacer ring structure in bearing band, this kind of design due to the limitation of middle spacer ring, when bearing bears heavy duty
When, in design, roller size and length cannot further optimize, and there is roller due to askew caused by internal friction
Tiltedly, skidding.
The content of the invention
For deficiency of the prior art, the present invention is intended to provide a kind of, to cause that rolling element structure is optimized new
Spheric roller bearing.
In order to solve the above problems, technical solution of the invention is：A kind of new spherical roller bearing, including it is outer
Circle, inner ring, two row rollers and two corresponding retainers；Four lock points are provided with each pocket hole of described retainer.
The beneficial effects of the invention are as follows：This kind of structure design so that rolling element structure is optimized, so as to increased axle
The bearing capacity held, due to eliminating spacer ring, it is to avoid rolling element is contacted with spacer ring, reduces frictional resistance, improves bearing
Rotating speed and life-span.
Brief description of the drawings
Accompanying drawing 1 is the front view of the embodiment of the present invention；
Accompanying drawing 2 is the view of the retainer of the embodiment of the present invention.
In figure：1st, outer ring, 2, inner ring, 3, roller, 4, retainer, 5, pocket hole, 6, lock point.
Specific embodiment
The present invention is described further below in conjunction with the accompanying drawings.
New spherical roller bearing, including outer ring 1, inner ring 2, two row rollers 3 and two corresponding retainers 4；Described
Four lock points 6 are provided with each the pocket hole 5 of retainer 4.Retainer 4 is using steel plate punched, one side double locking positions structure, it is ensured that roller
3 steady operating within the bearing, it is to avoid roller 3 due to crooked, skidding caused by internal friction, in unsupported area
Roller 3 is controllable, makes roller 3 when load region is entered in correct position, if bearing failure, it is also possible to which reduction seizes risk.
Claims (1)
1. new spherical roller bearing, it is characterised in that：Including outer ring（1）, inner ring（2）, two row rollers（3）It is corresponding with two
Retainer（4）；Described retainer（4）Each pocket hole（5）Inside it is provided with four lock points（6）.
