Abstract

The invention discloses an improved full complement cylindrical roller bearing which is characterized by being composed of an inner ring, an outer ring, a cylindrical roller and a loose rib, wherein the inner ring and the outer ring are respectively provided with a raceway, the cylindrical roller is fully complemented between two raceways, and the outer side of the inner roller is provided with a flat baffle.

Description

A kind of improved full-complement cylinder roller bearing
Technical field
The field of bearings that the present invention relates to use in the machinery relates to a kind of improved full-complement cylinder roller bearing concretely.
Background technique
Along with the continuous development of industry, bearing industry is also in continuous development.At the kind of the demand bearing of different industries in continuous increase.Roller bearing just belongs to a series of bearing, 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, used widely.The shortcoming of roller bearing 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.At present roller bearing generally adopts the structure with retainer, cylindrical roller can't completely adorn with raceway in, bearing can't reach its maximum load-carrying capacity.And when axial amount of deflection is big, can't run well, and then influence the normal operation of main frame.
Summary of the invention
Defective in view of existing procucts exist the purpose of this invention is to provide a kind of improved full-complement cylinder roller bearing.
For achieving the above object, a kind of improved full-complement cylinder roller bearing of the technology used in the present invention solution is characterized in that: be made of inner ring, outer ring, cylindrical roller, loose rib; Be respectively equipped with raceway on inner ring and the outer ring, cylindrical roller is completely adorned between two raceways, in roll the outside and be provided with flat baffle plate.
On the axial section of described outer ring, it is circular-arc that external diameter is, and the outer ring wall thickness is 3-4 times of the inner ring wall thickness.
Appearance of the present invention adopts improper heat treatment, and the surface hardening layer depth is 5mm, and abrasive resistance improves 18%-20%, and bearing life increases 14%-20%.
The present invention compared with prior art has following outstanding advantage and good effect:
1, the larger radius of curvature of outer ring axial section top external diameter, cylindrical roller can have certain relative displacement in the axial direction, makes the present invention have certain aligning ability, improves the overall performance of bearing, increases the using scope of bearing; Avoided simultaneously edge stress to concentrate to greatest extent and caused the improper damage of bearing, increased the service life.
2, the present invention adopts the structure of no retainer, and in limited space, bearing cross section, reasonable Arrangement cylindrical roller as much as possible makes bearing reach maximum load-carrying capacity.
4, adopt improper heat treatment process, increase bearing parts surface hardening layer depth, improve abrasive resistance and bearing life.
Description of drawings
Fig. 1 is a structural representation of the present invention
Embodiment
Reference character shown in Figure 1 is as follows: outer ring 1, cylindrical roller 2, inner ring 3, flat baffle plate 4.
In the schematic representation of a kind of improved full-complement cylinder roller bearing shown in Figure 1, its main structure comprises: inner ring 3, outer ring 1, cylindrical roller 2, loose rib 4; Be respectively equipped with raceway on inner ring 3 and the outer ring 1, cylindrical roller 2 is completely adorned between two raceways, in roll 4 outsides and be provided with flat baffle plate 4.
