Description
Technical field
The present invention relates to a kind of pressure roller bearing of papermaking equipment drive end, especially relate to three collar bearings that a kind of inside and outside assembly is cylindrical roller.
Background technique
In paper industry, the roller shell of crown controlled roll is round fixing roll shaft rotation, and the bearing on the pressure roller requires to possess good error of centralization compensation ability and high bearing capacity.A large amount of uses at present is the selfaligning roller bearing of biserial on the pressure roller.When all adopting aligning roller; Usually bearing capacity is not enough and cause bearing life low; When adopting spheric roller bearing and roller bearing to make up the centre circle that guides rotation; It is oversize to cause the bearing radial space to occupy again, thereby must reduce the problem of rolling element size, makes that the bearing capacity of bearing reduces, the lost of life.
Summary of the invention
The objective of the invention is the deficiency for solving the problems of the technologies described above, three collar bearings that provide a kind of inside and outside assembly to be cylindrical roller have bearing capacity height, precision height, advantage easy for installation, as to be easy to safeguard, save installing space.
The present invention is the deficiency that solves the problems of the technologies described above; The technological scheme that is adopted is: a kind of inside and outside assembly is three collar bearings of cylindrical roller; Comprise outer ring, centre circle and inner ring, be provided with the rolling element I in the raceway between outer ring and centre circle, be provided with the rolling element II in the raceway between centre circle and inner ring; Rolling element I and rolling element II all are arranged in the retainer separately; Described rolling element I and rolling element II are cylindrical roller, and the outer diametric plane of outer ring is a spherical, are provided with one deck wearing layer on the spherical surface of outer ring.
The end face of described centre circle is provided with tapped hole.
External diameter is the cylndrical surface in the described inner ring.
Described centre circle internal diameter is worn three ribs, is respectively both ends of the surface rib and a centre rib, and the centre circle external diameter is the cylndrical surface.
The internal diameter of described outer ring is worn three ribs, is respectively both ends of the surface rib and a centre rib.
Because the bearing on the pressure roller requires to possess good error of centralization compensation ability; It is therefore a large amount of at present on the pressure roller that what use is that the selfaligning roller bearing of biserial meets the demands; Yet because this class bearing often causes bearing life low owing to bearing capacity is not enough, and other class bearing can't use, and therefore the pressure roller bearing at the papermaking equipment drive end often needs to change; Not only delay work and mistake, but also wasted a large amount of financial resources.
The invention has the beneficial effects as follows: the present invention is designed to spherical through the outer diametric plane with the outer ring; The outer spherical surface of outer ring cooperates with the split bearing seat of band inner ball surface; The roller that satisfies in the paper-making process is the aligning requirement, and the high-abrasive material that outer diametric plane applies increases the sliding friction pair life-span of external diameter outer spherical surface and bearing support inner ball surface; Two roller assemblies all adopt roller bearing, under the certain prerequisite of radial space, compare with adopting spheric roller bearing, can increase roller diameter or roller number, thereby increase the bearing capacity of bearing, under the identical external load, increase bearing life; Outer diametric plane of inner ring and the outer diametric plane of centre circle are the cylndrical surface, and outer ring aperture surface and centre circle aperture surface reduce technology difficulty greatly for the cylndrical surface of band rib, improve the bearing machining accuracy.
The present invention is a concrete working condition of considering papermaking equipment, and the inside and outside rolling element assembly of design is three collar bearings of cylindrical roller structure, and the outer ring is static with inner ring during the bearing working of design, and centre circle rotates.That utilizes diametric plane and bearing support aperture surface outside the outer ring in the design makes the self adaption aligning movingly, has rationally utilized the space.This design increases bearing capacity, the life-span of bearing, and compact structure is easy to maintenance.

Embodiment
As shown in the figure, a kind of inside and outside assembly is three collar bearings of cylindrical roller, comprises outer ring 1, centre circle 4 and inner ring 7; Be provided with rolling element I 2 in the raceway between outer ring 1 and centre circle 4; Be provided with rolling element II 5 in the raceway between centre circle 4 and inner ring 7, rolling element I 2 is arranged in the pocket hole of retainer I 3, and rolling element II 5 is arranged in the pocket hole of retainer II 6; Described rolling element I 2 is cylindrical roller with rolling element II 5, and the outer diametric plane of outer ring 1 is a spherical.The outer ring outer spherical surface not only satisfies the aligning requirement with cooperating of bearing support inner ball surface; The also axial displacement of axes bearing outer-ring; At this moment, the external diameter sphere of outer ring and bearing support internal diameter sphere are sliding friction pair, thereby on the outer diametric plane of outer ring, are coated with coating rubbing-layer to improve bearing life.The external diameter middle part of outer ring has oil groove, and 120 degree, three oil holes spaced apart, for the outer assembly of roller provides lubricated.
The present invention, the end face of bearing centre circle 4 is provided with tapped hole and is connected with the rotation roller, during the motion of rotation roller, drives the centre circle rotation through attachment screw, and the centre circle of rotation drags the outer assembly of roller and the roller inner assembly is done rotation and revolution motion; Cylindrical roller separates through the brass retainer, and retainer guiding rolling element rotates.
The present invention, external diameter is the cylndrical surface and does not all have rib in the described inner ring, and is separable with interior roller assembly; The centre circle internal diameter is worn three ribs; Be respectively both ends of the surface rib and a centre rib, be used to limit the axial position of two row rollers in the roller assembly in the bearing, the centre circle external diameter is the cylndrical surface and does not have rib; Make that this bearing centre circle and outer roller assembly are separable, be easily installed in dismounting; The internal diameter of outer ring is worn three ribs; Be respectively both ends of the surface rib and a centre rib; The outer ring outer spherical surface applies one deck wear-resistant material layer; The hardness of wearing layer is HRC65-80, and the thickness of wearing layer is preferably used 2-3 ㎜, the axial position of two row rollers in three outer roller assemblies of rib restriction bearing that the outer ring aperture surface is provided with.
The present invention; Described rolling element I is arranged between outer ring aperture surface and the outer diametric plane of centre circle; The rolling element I concerns to the position through three shelves margin dead axles on the outer ring; Described rolling element II is arranged between centre circle aperture surface and the outer diametric plane of inner ring, and the rolling element II concerns to the position through three shelves margin dead axles on the centre circle.
The present invention; When roller system receives radial force effect generation deflection deformation; Run-off the straight between the turning axle of centre circle and the horizontal line, because interior roller assembly is roller bearing with outer roller assembly, the outer roller assembly active force of centre circle inclined push is rib in the outer ring; Thereby make the outer ring twist, realize aligning.
The inner ring of bearing cooperates with axle, and the inner ring middle part has 120 degree, three oil holes spaced apart, for the roller inner assembly provides lubricated.
