The model utility content
The purpose of this utility model, be to provide a kind of compact type crossed roller flange bearing, and this bearing is combined into conventional crossed roller bearing, flange bearing, by tapered roller and steel ball alternative arrangement, possesses the comprehensive bearing of two kinds of bearing characteristicses.This bearing has that rigidity is high, reliability is high, load is high, long service life, smooth running, closely and the characteristics such as still can guarantee accurately at a high speed.Can bear the directive loads such as radial load, axial load and moment load simultaneously.
The technological scheme adopted is:
A kind of compact type crossed roller flange bearing, comprise outer ring, inner ring, combined rolling body and dust cover, it is characterized in that:
Described combined rolling body, comprise tapered roller, steel ball; Tapered roller and steel ball are arranged in a crossed manner, and are provided with spacing block between each tapered roller and a corresponding steel ball, to prevent collision or the slippage between rolling element.One row combined rolling body is installed in by the raceway formed between outer ring and inner ring.
The profile of outer ring is the flange shape, and four bolts hole are arranged, and the internal raceways cross section of outer ring is reversed V-shape, and an inclined-plane of reversed V-shape raceway is tapered roller raceway, and the raceway wrapping angle is greater than 45 degree, so can bear larger axis to load and radial load.There is the first spherical arc raceway at another middle part, inclined-plane of above-mentioned reversed V-shape raceway, the large end face of the corresponding tapered roller of the first spherical arc raceway, and inclined-plane, the both sides while of the first spherical arc raceway is as the rib of tapered roller and steel ball.
Inner ring is comprised of the first half inner rings and the second half inner rings, and the inner ring raceway cross section after combination is V-arrangement.The inclined-plane of corresponding the first half inner rings of the V-arrangement raceway of inner ring is tapered roller raceway, and there is the second spherical arc raceway at the middle part on the inclined-plane of corresponding the second half inner rings of the V-arrangement raceway of inner ring, for steel ball rolling channel, the small end face of the corresponding tapered roller of the second spherical arc raceway, inclined-plane, the both sides while of the second spherical arc raceway is as the rib of tapered roller and steel ball.There is certain interval between the second spherical arc raceway and circular cone rolling element small end face.In bearing movable, the second spherical arc raceway does not bear the load of tapered roller.
The exterior edge face of outer ring is provided with dust cover and the first seal ring, is oil sealing and dust cover combination; The inner of outer ring and the second half inner ring contact position are provided with the second seal ring, for many contact seals, thereby improved the pollution of pollutants such as preventing dust, fine particle, the utility model raceway is the line contact with the direction that contacts of roller, another direction is the some contact, this Points And lines contact makes the speed of bearing and bearing capacity obtain taking into account, and can bear radial load, axial load and tilting moment, can be used for the application of complicated applied force simultaneously.
The utlity model has following advantage:
1, owing to being to have applied circular cone and the steel ball center line is 90 ° of cross arrangements, there is outstanding running accuracy.
2, the size of Internal and external cycle, by inferior limit ground miniaturization, has been saved axial dimension.
3, the Points And lines contact makes the speed of bearing and bearing capacity obtain taking into account.
4, can bear radial load, axial load and tilting moment, can be used for the application of complicated applied force simultaneously.
5, to place unidirectional, axially loaded, good adaptability is arranged, the place of application has obtained expansion.
The utility model is best suited for the purposes of revolving table, mechanism hand rotary part, precision rotation worktable, medical machine of the joint portion of industrial robot or rotary part, machining center etc., alternative biserial angular contact bearing, double-row conical bearing, especially alternative existing automobile hub unit bearing, can use as a kind of novel automobile hub unit bearing.
