Abstract
The utility model relates to a full-complement cylinder roller bearing, which comprises an inner ring, an outer ring, a plurality of cylindrical rollers, roller rails, and loose ribs, wherein the cylindrical rollers are arranged between the inner ring and the outer ring, and a plurality of roller rails and loose ribs are arranged among the cylindrical rollers. The long curvature radius of the external diameter of the axial section of the outer ring can enable the cylinder roller bearing to have a certain aligning capability, thereby enabling a host machine to have better using performance; and since the outer diameter of the outer ring is designed into an abnormal shape, the abnormal damage of the bearing, which is caused by the concentration of edge stress, is maximally avoided and the service life is prolonged; and in comparison with multiple schemes and multiple parameter designs, the cylindrical rollers can be reasonably arranged as many as possible, and the bearing capability of the bearing can achieve the ideal state; and due to the adoption of abnormal thermal-processing technology, the depth of the hardened layer on the surface of a bearing part is increased, the abrasion resistance of the bearing is enhanced and the service life of the bearing is prolonged.
Description
Technical field
The utility model relates to field of bearings, concretely, relates to a kind of full-complement cylinder roller bearing.
Background technique
Rolling bearing is one of widely used mechanical parts in the machinery, and it is to rely on rolling between primary component to contact to support rotational parts.Compare with sliding bearing, rolling bearing have start flexibly, surface friction drag is little, efficient is high, lubricated easy, and be easy to advantage such as exchange, so be widely used.Its shortcoming is that impact resistance is relatively poor, and noise is arranged during high speed, and operating life is not as good as the sliding bearing of liquid friction.
When the center line of axle does not overlap with the bearing support center line and when angular error is arranged, or stressed and crooked or when tilting because of axle, can cause the inner peripheral axis generation deflection of bearing.
Full-complement cylinder roller bearing designs in order to bear heavy load.Under same width, this bearing is compared with traditional band retainer bearing, has high bearing capacity, and radial cross section is little, can save the space, but does not possess the aligning ability.
Summary of the invention
The purpose of this utility model provides that a kind of radial load is big, rotating speed is low, possesses the full-complement cylinder roller bearing of certain aligning ability.
The utility model full-complement cylinder roller bearing is made of inner ring, outer ring, several cylinders roller, roller track, loose rib; Cylindrical roller has several roller track and loose rib in the middle of cylindrical roller and the cylindrical roller between inner ring and outer ring.
On the axial section of described outer ring, external diameter is big circular-arc of radius of curvature.
Described outer ring wall thickness is more than three times of inner ring wall thickness.
The utility model compared with prior art has following beneficial effect:
1, the larger radius of curvature of outer ring axial section top external diameter can make roller bearing have certain aligning ability, makes main frame obtain good usability.
2, because the outer ring external diameter is designed to the profile state of abnormity, avoid edge stress to concentrate to greatest extent and caused the improper damage of bearing, increase the service life.
3, compare through multi-scheme and multi-parameter design, in limited space, bearing cross section, reasonable Arrangement cylindrical roller as much as possible makes the bearing capacity of bearing reach the most desirable.
4, adopt improper heat treatment process, increase bearing parts surface hardening layer depth, improve abrasive resistance and bearing life.
Description of drawings

Embodiment
Reference character shown in Figure 1 is as follows: outer ring 1, roller track 2, cylindrical roller 3, inner ring 4, loose rib 5.
The utility model full-complement cylinder roller bearing is made of inner ring 4, outer ring 1, several cylinders roller 3, roller track 2, loose rib 5; Cylindrical roller 3 has several roller track 2 and loose rib 5 in the middle of cylindrical roller 3 and the cylindrical roller 3 between inner ring 4 and outer ring 1.
Described outer ring 1 wall thickness is more than three times of inner ring 4 wall thickness, and inner ring 4 wall thickness are thinner, and outer ring 1 wall thickness is very thick.
On 1 axial section of described outer ring, external diameter is big circular-arc of radius of curvature, make can not aligning roller bearing have certain aligning, make main frame obtain good use.The special-shaped state of outer ring 1 external diameter has been avoided edge stress to concentrate to greatest extent and has been caused the improper damage of bearing, prolongs bearing working life.
In limited space, bearing cross section, reasonable Arrangement cylindrical roller 3 as much as possible makes the bearing capacity of bearing reach the most desirable.
