Abstract
The utility model relates to a bearing, in particular to an angular contact cylindrical roller bearing. The angular contact cylindrical roller bearing comprises a bearing outer ring, a bearing inner ring and an angular contact roller bearing holder mounted between the bearing outer ring and the bearing inner ring; a plurality of cylindrical rollers are assembled uniformly on the angular contact roller bearing holder; and the two end surfaces of the cylindrical roller are opposite to the bearing outer ring and the bearing inner ring respectively. The angular contact cylindrical roller bearing provided by the utility model combines the advantages of an angular contact bearing and a cylindrical roller bearing, improves the rigidity of the bearing, improves the load-carrying capacity of the bearing and prolongs the rated service life of the bearing; moreover, the bearing can be applied to the occasions that angular contact bearings and cylindrical roller bearings are required originally, so that the installation space of components is saved greatly.
Description
Technical field
The utility model relates to a kind of bearing, relates in particular to a kind of angle contacting roller bearing.
Background technique
In ten big types of the traditional bearings, the branch of angular contact bearing and roller bearing is arranged, and angular contact bearing is main with angular contact ball bearing, angular contact ball bearing can bear radial load and axial load simultaneously.Can under high rotational speed, work.Wrapping angle is big more, and axial carrying capacity is high more.Highi degree of accuracy and high-speed bearing are got 15 degree wrapping angles usually.Under responsive to axial force, wrapping angle can increase.Single-row angular contact ball bearing can only bear the axial load of a direction, when bearing radial load, will cause additional axial force.And can only axes or shell in the axial displacement of a direction.If duplex is installed in pairs, make the outer ring of pair of bearings relative, promptly wide end surface is to wide end surface, and narrow end surface is to narrow end surface.Can avoid causing additional axial force like this, and can axle or shell are limited in the axial internal clearance scope at both direction.
Angular contact ball bearing can have relative displacement because of the raceway of its Internal and external cycle on horizontal axis; So can bear radial load and axial load simultaneously---joint load (single-row angular contact ball bearing can only bear folk prescription to axial load, therefore generally all often adopts paired mounting).The material of retainer has brass, synthetic resin etc., according to bearing type, service condition and distinguish.
Cylindrical roller and raceway are line contact bearing.Load carrying capacity is big, mainly bears radial load.Rolling element and the friction of lasso rib are little, are suitable for high speed rotating.Have or not rib according to lasso, can divide single row bearings such as NU, NJ, NUP, N, NF are arranged, reach double row bearings such as NNU, NN.This bearing is the separable structure in inner ring, outer ring.Inner ring or outer ring do not have the roller bearing of rib, and its inner ring and outer ring can relatively move to axial, use so can be used as the free end bearing.A certain side in inner ring and outer ring has two ribs, and the lasso of opposite side has the roller bearing of single rib, can bear a direction axial load to a certain degree.General use steel plate pressing cage, or Cuprum alloy car system retainer.But also some uses polyamide shaping retainer.
In the existing part assembling; Usually need angular contact bearing and roller bearing be used in combination; Though combined the advantage of angular contact bearing and roller bearing like this; Reach the effect of better use, but in the part installation process, can occupy a lot of spaces, make troubles for follow-up processing.
The model utility content
The technical problem that the utility model will solve is: in order to save the installing space of component, and combine the advantage of angular contact bearing and roller bearing, the utility model provides a kind of angle contacting roller bearing.
The utility model solves the technological scheme that its technical problem adopted: a kind of angle contacting roller bearing; Comprise bearing outer ring, bearing inner race and be installed in bearing outer ring and bearing inner race between the angular contact roller bearing retainer; Evenly be equipped with the roller of several cylinders shape on the described angular contact roller bearing retainer, the both ends of the surface of described columniform roller are respectively with respect to bearing outer ring and bearing inner race.
In order to improve the rigidity of bearing, the inner ring of described angular contact roller bearing retainer has lug, nib.
In order to improve the bearing load ability, rectangular triangle in the cross section of described bearing outer ring and bearing inner race and hypotenuse are relative, and the length of described hypotenuse is greater than the diameter of described columniform roller.
For the ease of the cooperate installation of bearing with bearing, the corner of described bearing outer ring and bearing inner race outer surface is and leads fillet.
The beneficial effect of the utility model is; The angle contacting roller bearing of the utility model in conjunction with the advantage of angular contact bearing and roller bearing, has improved the rigidity of bearing; Increased the load capacity of bearing; Prolong the rating life of bearing, made script need to use the occasion of angular contact bearing and roller bearing only need use the utility model to get final product, saved the installing space of component greatly.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the optimum embodiment's of the utility model angle contacting roller bearing structural representation.
Fig. 2 is the sectional view of Fig. 1.
Among the figure 1, bearing outer ring, 2, bearing inner race, 3, the angular contact roller bearing retainer, 3-1, lug, nib, 4, roller.
Embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the schematic representation of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Shown in Figure 2 like Fig. 1; Be the optimum embodiment of the utility model angle contacting roller bearing; Comprise bearing outer ring 1, bearing inner race 2 and be installed in bearing outer ring 1 and bearing inner race 2 between angular contact roller bearing retainer 3; Evenly be equipped with the roller 4 of several cylinders shape on the angular contact roller bearing retainer 3, the both ends of the surface of columniform roller 4 are respectively with respect to bearing outer ring 1 and bearing inner race 2.The inner ring of angular contact roller bearing retainer 3 has lug, nib 3-1.The rectangular triangle in cross section and the hypotenuse of bearing outer ring 1 and bearing inner race 2 are relative, and the length of hypotenuse is greater than the diameter of described columniform roller 4, and the corner of bearing outer ring 1 and bearing inner race 2 outer surfaces is and leads fillet.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
