Description

A kind of roller bearing
Technical field
The utility model belongs to field of mechanical technique, is specifically related to a kind of roller bearing.
Background technique
Sealed type deep groove ball bearing is due to good seal performance, and the advantage such as limit speed is high, lightweight, is widely used in machine field; But for the motor of some outdoor uses, its large applying working condition of loading poor (bearing capacity requires large also requirement can bear certain thrust load), sealed type deep groove ball bearing is just difficult to meet usage requirement, damages comparatively fast, changes frequent.Though existing full-complement cylinder roller bearing has higher bearing capacity, but bearing roller is without accurate location, do not there is sealing at the easy axial float of motor speed lower bearing and bearing, can not directly apply in motor, and, the main force bearing point of vertical axis aerogenerator concentrates on main shaft, need main shaft bearing to there is larger bearing capacity, main shaft bottom end bearing is used for bearing radial force and tilting moment, but because space is little, require very strict to bearing boundary dimension especially radial dimension, make bearing used in, outer ring is thin-walled parts, bearing load carrying capacity reduces, existing bearing cannot meet such usage requirement.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist for prior art, has proposed a kind of good seal performance, radially the large roller bearing of bearing capacity.
The purpose of this utility model can realize by following technical proposal: a kind of roller bearing, include outer ring, inner ring and be located at outer ring and inner ring between cylindrical roller, on the outer wall of described outer ring, offer locking groove, described inner ring is provided with the axial elasticity back-up ring to cylindrical roller axial limiting, between described outer ring and inner ring, be provided with dust slinger, described cylindrical roller inside has through hole, described through hole is coaxial with cylindrical roller, in described through hole, pillar is installed, the two ends of described pillar are separately installed with retainer packing ring.
In above-mentioned a kind of roller bearing, described outer ring and cylindrical roller angle position offer oil hole.
In above-mentioned a kind of roller bearing, inner ring external diameter is provided with the mounting groove of installing for axial elasticity back-up ring, and an axial elasticity back-up ring radially side embeds in mounting groove, forms the gap that enters bearing inside for lubricant oil between opposite side and outer ring.
In above-mentioned a kind of roller bearing, described mounting groove is annular groove, and the radial cross section of axial elasticity back-up ring is and the rectangle of mounting groove adaptation.
In above-mentioned a kind of roller bearing, the radial cross section of described dust slinger is " L " shape, and horizontal component is resisted against on outer ring.
Compared with prior art, the utlity model has following advantage: this cylindrical roller makes bearing have larger radial load,, prevent cylindrical roller axial float in the time of work, and make bearing can bear certain thrust load cylindrical roller axial limiting by circlip, bearing forms certain sealing by dust slinger, optimize bearing working environment, extend bearing working life, locking groove design can not be out of shape outer ring, be difficult for producing relative sliding, improve working life.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model one preferred embodiment.
In figure, 1, outer ring; 2, inner ring; 3, cylindrical roller; 4, locking groove; 5, circlip; 6, dust slinger; 7, pillar; 8, retainer packing ring; 9, oil hole.
Embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, this cylindrical roller 3 bearings include outer ring 1, inner ring 2 and be located at outer ring 1 and inner ring 2 between cylindrical roller 3, on the outer wall of described outer ring 1, offer locking groove 4, outer ring 1 offers oil hole 9 with cylindrical roller 3 angle positions, described inner ring 2 is provided with the axial elasticity back-up ring 5 to cylindrical roller 3 axial limitings, between described outer ring 1 and inner ring 2, is provided with dust slinger 6.
This cylindrical roller 3 makes bearing have larger radial load, by circlip 5 to cylindrical roller 3 axial limitings, prevent cylindrical roller 3 axial floats in the time of work, and make bearing can bear certain thrust load, bearing forms certain sealing by dust slinger 6, optimize bearing working environment, extend bearing working life, locking groove 4 designs can not be out of shape outer ring, are difficult for producing relative sliding, improve working life.
Cylindrical roller 3 inside have through hole, described through hole is coaxial with cylindrical roller 3, pillar 7 is installed in described through hole, the two ends of described pillar 7 are separately installed with retainer packing ring 8, the raceway bus of bearing inner race 2 and bearing outer ring 1 is straight line, and both are thin-walled parts, described bearing outer ring 1 wall thickness is 37.5mm, described bearing inner race 2 wall thickness are 39.5mm, described cylindrical roller 36 diameters are 60mm, long 70mm, and be that line contacts with raceway, pass through accurate Calculation, suitably reduce rolling element diameter, in having strengthened, outer ring 1 wall thickness, and adopt the pattern that completely fills roller, improve bearing load carrying capacity, the load-carrying properties that significantly promote bearing in the situation that not strengthening bearing boundary dimension, meet the usage requirement of main shaft of vertical-shaft wind driven generator bearing more.
As preferably, inner ring 2 is provided with the mounting groove of installing for axial elasticity back-up ring 5, an axial elasticity back-up ring 5 radially side embeds in mounting groove, between opposite side and outer ring 1, form the gap that enters bearing inside for lubricant oil, mounting groove is to paste to face the annular groove that inner ring 2 arranges, and the radial cross section of axial elasticity back-up ring 5 is and the rectangle of mounting groove adaptation.
As preferably, the radial cross section of dust slinger 6 is " L " shape, and horizontal component is resisted against on outer ring 1, dust slinger 6 and outer ring 1 internal diameter interference fit.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendments or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
