Abstract
The invention discloses a kind of full-complement cylinder roller bearing, including inner ring, outer ring, cylindrical roller, auxiliary roller and loose rib；Being respectively equipped with raceway on inner ring and outer ring, cylindrical roller is arranged in the raceway between inner ring and outer ring, is provided with loose rib outside interior rolling；Being provided with auxiliary roller between adjacent column roller, auxiliary roller is all conflicted with adjacent two cylindrical rollers cooperation, makes to be formed between adjacent two cylindrical rollers interval, and auxiliary roller is bearing on the raceway of outer ring through two adjacent cylindrical rollers.On the axial section of outer ring, external diameter is arc-shaped, and 56 times that outer ring wall thickness is inner ring wall thickness.Cylindrical roller can have certain relative displacement in the axial direction so that the present invention has certain regulation of mental activities ability, improves the overall performance of bearing, increases the range of bearing；Avoid edge stress concentration simultaneously to greatest extent and cause the improper damage of bearing, reduce the operating noise of bearing, increase the service life.
Description
Technical field
The present invention relates to field of bearings, particularly relate to a kind of full-complement cylinder roller bearing.
Background technology
Full-complement cylinder roller bearing is big due to its radial direction bearing capacity, under same width, and this bearing and traditional band
Retainer bearing is compared, and has high bearing capacity, and radial section is little, can save space, it is adaptable to bear heavy load with
Impact load, cylinder roller bearing is to bear radial load, and the bearing of part Internal and external cycle all band ribs can bear necessarily
Axial force.In order to be able to bear bigger radial load, full cylinder roller bearing can be designed and manufactured into.
At present, completely cylinder roller bearing is in use, when roller is through non-bearing district, and meeting between two adjacent rollers
Colliding and produce collision sound, the occasion tighter at noise requirements can not meet use requirement.
Summary of the invention
It is an object of the invention to provide one and be avoided that cylindrical roller collides, the full-complement cylinder roller bearing that noise is low.
For achieving the above object, the invention provides following scheme: a kind of full-complement cylinder roller bearing, including inner ring 4, outer
Circle 1, cylindrical roller 2, auxiliary roller 5 and loose rib 3；Raceway, described cylinder it is respectively equipped with on described inner ring 4 and described outer ring 1
Roller 2 is arranged in the raceway between described inner ring 4 and described outer ring 1, is provided with described loose rib 3 outside described interior rolling；Adjacent
Being provided with described auxiliary roller 5 between described cylindrical roller 2, described auxiliary roller 5 all supports with adjacent two described cylindrical rollers 2
Touching and coordinate, make to be formed between adjacent two described cylindrical rollers 2 interval, described auxiliary roller 5 is through two adjacent described cylinders
Roller 2 is bearing on the raceway of described outer ring 1.
Optionally, on the axial section of described outer ring 1, external diameter is arc-shaped, and described outer ring 1 wall thickness is described inner ring
4.2-6.5 times of 4 wall thickness.
Optionally, described auxiliary roller 5 uses structural steel to make.
Optionally, the diameter of described auxiliary roller 5 is less than the diameter of described cylindrical roller 2, the length of described auxiliary roller 5
Less than the length of described cylindrical roller 2, the 1/3 3/5 of the diameter of a diameter of described cylindrical roller 2 of described auxiliary roller 5, institute
State a length of described cylindrical roller 2 of auxiliary roller 5 length 2/3 3/4.
The specific embodiment provided according to the present invention, the invention discloses techniques below effect:
1, the larger radius of curvature of outer ring axial section top external diameter, cylindrical roller can have certain phase para-position in the axial direction
Move so that the present invention has certain regulation of mental activities ability, improve the overall performance of bearing, increase the range of bearing；?
The edge stress concentration that avoids of limits causes the improper damage of bearing, increases the service life.
2, the present invention uses the structure without retainer, in limited bearing sections space, and the circle that reasonable Arrangement is the most
Post roller, makes bearing reach maximum load-carrying capacity.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
It is an object of the invention to provide a kind of full-complement cylinder roller bearing, a kind of full-complement cylinder roller bearing, including inner ring
4, outer ring 1, cylindrical roller 2, auxiliary roller 5 and loose rib 3；It is respectively equipped with raceway on described inner ring 4 and described outer ring 1, described
Cylindrical roller 2 is arranged in the raceway between described inner ring 4 and described outer ring 1, is provided with described loose rib 3 outside described interior rolling；
Described auxiliary roller 5, described auxiliary roller 5 and adjacent two described cylindrical rollers 2 it are provided with between adjacent described cylindrical roller 2
All conflict cooperation, make to be formed between adjacent two described cylindrical rollers 2 interval, described in described auxiliary roller 5 is adjacent through two
Cylindrical roller 2 is bearing on the raceway of described outer ring 1.
On the axial section of described outer ring 1, external diameter is arc-shaped, and described outer ring 1 wall thickness is described inner ring 4 wall thickness
4.2-6.5 again.
Described auxiliary roller 5 uses structural steel to make.
The diameter of described auxiliary roller 5 is less than institute less than the diameter of described cylindrical roller 2, the length of described auxiliary roller 5
State the length of cylindrical roller 2, the 1/3 3/5 of the diameter of a diameter of described cylindrical roller 2 of described auxiliary roller 5, described auxiliary
The 2/3 3/4 of the length of a length of described cylindrical roller 2 of roller 5.
Find through lot of experiments, in the case of auxiliary roller can make to form interval between adjacent column roller, auxiliary
The diameter helping roller is the least, and radial force and shock loading that full-complement cylinder roller bearing can bear are the biggest, but the making of bearing
Shorter with the life-span, the lubricant effect of full-complement cylinder roller bearing is the best；On the contrary, the diameter of auxiliary roller is the biggest, can increase accordingly
In the service life of bearing, improve the lubrication circumstances of bearing, but the bearing capacity of bearing and impact resistance have declined.
Described auxiliary roller 5 a diameter of described cylindrical roller 2 diameter 1/3 3/5 in the case of, bearing each
Aspect nominal parameter is relatively good, as a example by the 34% of the diameter of a diameter of described cylindrical roller 2 of described auxiliary roller 5, full
Dress cylinder roller bearing adds 21%-27% relative to the conventional cylindrical roller bearing life-span, and dynamic load rating improves 48%.
Principle and the embodiment of the present invention are set forth by specific case used herein, saying of above example
Bright method and the core concept thereof being only intended to help to understand the present invention；Simultaneously for one of ordinary skill in the art, foundation
The thought of the present invention, the most all will change.In sum, this specification content is not
It is interpreted as limitation of the present invention.
