Abstract
The invention discloses a large-size plain-and-ball cylindrical roller bearing and relates to the field of bearings. An inner sphere outer ring, an outer sphere center ring, an inner ring and a rolling body that is provided with a retainer component and arranged between the outer sphere center ring and the inner ring to achieve the purposes of self-aligning and axial displacement; and as the inner ring is not provided with a flange, the bearing can serve as an axial play bearing to achieve the axial displacement, achieve transmission of the movement and load in a large span, bear a higher radial load and make up an angle error caused by a manufacturing error and a mounting error to realize self-aligning, overcomes extension caused by the shaft, and realizes the axial displacement.
Description
[technical field]
The present invention relates to field of bearings, especially relate to a kind of large-scale slip and rolling combination cylinder roller bearing.
[background technique]
Known, existing bearing comprises bearing inner race, bearing outer ring, one group of rolling element and retainer, and described one group of rolling element is distributed in the described retainer, described retainer is between described bearing inner race and described bearing outer ring, and the profile of described bearing outer ring is cylindrical body.The configuration of bearing generally is divided into fixed end and free end, be installed in respectively the two ends of axle, then pack in two bearing supports, because there is certain deviation in the axle center of two bearing supports, and the profile of bearing outer ring is cylindrical body, to bear larger radial load for the large cylindrical roller bearing, when the needs bearing stride is larger, the angular error that causes owing to foozle and alignment error, so also so that aligning performance is the performance of angular adjustment can't realize, and can carry out self-aligning for having at present, and realizing the bearing of the characteristics of axial displacement, the application in the large size bearing field seems more and more important.
[summary of the invention]
In order to overcome the deficiency in the background technique, the invention discloses a kind of large-scale slip and rolling combination cylinder roller bearing, the present invention utilizes inner ball surface outer ring, outer spherical surface centre circle, inner ring and the rolling element with the retainer assembly that is provided with between described outer spherical surface centre circle and inner ring reaches the purpose of self-aligning and axial displacement.
In order to realize described goal of the invention, the present invention adopts following technological scheme:
A kind of large-scale slip and rolling combination cylinder roller bearing, comprise inner ball surface outer ring, outer spherical surface centre circle, inner ring, rolling element and retainer, its interior facade of described inner ball surface outer ring is inner ball surface, its outer facade of described outer spherical surface centre circle is outer spherical surface, described outer spherical surface centre circle places the inside, inner ball surface outer ring, form a bearing bush structure, be provided with inner ring in described outer spherical surface centre circle the inside, between outer spherical surface centre circle and inner ring, be provided with retainer, be provided with rolling element in the retainer, described outer spherical surface centre circle forms the outer ring of rolling element.
The bearing of described large-scale slip and rolling combination cylinder roller, described retainer are integral window type frame structure, adopt the brass material manufacturing.
The bearing of described large-scale slip and rolling combination cylinder roller, described rolling element is cylindrical roller, is at least single-row roller bearing.
The bearing of described large-scale slip and rolling combination cylinder roller, described inner ring is not for being with the rib inner ring.
Owing to adopted technique scheme, the present invention to have following beneficial effect:
Described large-scale slip and rolling combination cylinder roller bearing, by utilizing the inner ball surface outer ring, the outer spherical surface centre circle, inner ring and the rolling element with the retainer assembly that is provided with between described outer spherical surface centre circle and inner ring reach the purpose of self-aligning and axial displacement, rib is not with in the inner ring design, can be used as the play bearing, realize axial displacement, in motion between the large span of realization and the transmission of load, have and to bear larger radial load, the angular error that can remedy foozle and alignment error simultaneously and cause realizes self-aligning, overcome because stretching of axle realizes the bearing of axial displacement.

Fig. 1 is cross section structure schematic representation of the present invention.
Fig. 2 is overall structure schematic representation of the present invention.
Among the figure: 1, inner ball surface outer ring; 2, inner ring; 3, outer spherical surface centre circle; 4, rolling element; 5, retainer.
[embodiment]
By the following examples can be detailed explanation the present invention, disclose purpose of the present invention and be intended to protect all technological improvements in the scope of the invention.
By reference to the accompanying drawings 1 and 2 described large-scale slips and rolling combination cylinder roller bearing, comprise inner ball surface outer ring 1, outer spherical surface centre circle 3, inner ring 2, rolling element 4 and retainer 5, described inner ball surface outer ring 1 its interior facade is inner ball surface, described outer spherical surface centre circle 3 its outer facades are outer spherical surface, described outer spherical surface centre circle 3 places 1 the inside, inner ball surface outer ring, form a bearing bush structure, and concentric structure, be provided with inner ring 2 in described outer spherical surface centre circle 3 the insides, between outer spherical surface centre circle 3 and inner ring 2, be provided with retainer 5, be provided with rolling element 4 in the retainer 5, described outer spherical surface centre circle 3 forms the outer ring of roller bearing.
Implement large-scale slip of the present invention and rolling combination cylinder roller bearing, comprise inner ball surface outer ring 1, outer spherical surface centre circle 3, inner ring 2, rolling element 4 and retainer 5, inner ring 2 is not for being with the rib design, can be used as the free end bearing, realize axial displacement, retainer 5 is integral window type structure, has higher intensity, good frictional behaviour, vibration damping, antifriction, noise reduction, turn round the characteristics such as flexible, can realize higher precision, stability, the bearing bush structure that inner ball surface outer ring 1 and outer spherical surface centre circle 3 consist of, when the angle of arrival error, inner ball surface outer ring 1 is fixing, inner ring 2 drives rolling element 4, retainer 5 and outer spherical surface centre circle 3 swing adjustment together in the spherical raceway of inner ball surface outer ring 1, can compensate the diaxon bearing and misalign the concentric error that occurs, can realize the self-aligning requirement, and the spindle nose that described outer spherical surface centre circle 3 is bearing shell is the outer ring of roller bearing, thereby compact structure, therefore the invention solves and to satisfy the load requirement, the requirement that has again aligning function and axial displacement function has reached its bearing requirement in application.
Part not in the detailed description of the invention is prior art.
