Description
Technical field
This utility model belongs to field of bearings, a kind of double-layer rolling bearing.
Background technology
Bearing (Bearing) is a kind of important spare part in plant equipment in the present age.Its major function is to support machinery rotary body, reduces the coefficient of friction in its motor process, and ensures its rotating accuracy.
Rolling bearing is typically by outer ring, inner ring, rolling element and retainer four part composition, when using, inner ring is relatively rotated by rolling element with outer ring, although bearing all has sealing lid, but when working environment very severe, still it is very easy between inner ring and outer ring enter the impurity such as dust, dust is attached on rolling element, rolling element generation sharp wear, whole bearing is caused to be continuing with, now need to carry out bearing is replaced, but within being, due to bearing, the axis hole that by professional equipment axle is embedded into bearing in use, it is replaced bothering very much, and need permanent stopping the operation of a machine, affect production efficiency.
Utility model content
For the deficiencies in the prior art, this utility model provides one and has layer rolling body, after one layer of rolling element weares and teares, without whole bearing is taken off by machine, another layer of rolling element is used to continue to ensure the normal operation of machine, avoid the permanent machine that makes to stop, improving the double-layer rolling bearing of production efficiency.
For achieving the above object, this utility model provides following technical scheme: a kind of double-layer rolling bearing, including inner ring, outer ring and rolling element, centre circle it is additionally provided with between inner ring and outer ring, described rolling element includes the first rolling element and the second rolling element, described first rolling element is between inner ring and centre circle, described second rolling element is between centre circle and outer ring, it is provided with dismountable first fixture between described inner ring and centre circle, between described centre circle and outer ring, is provided with dismountable second fixture.
The most described first fixture and the second fixture are annular fixing plate, and the side of described inner ring, centre circle and outer ring all offers screw, and on described annular fixing plate, corresponding screw is provided with plate hole, is equipped with bolt in described plate hole and screw.
Further described bolt is dormant bolt, and described annular fixing plate respective panels hole site offers counterbore, and the head of described dormant bolt is positioned at counterbore.
Further described rolling element is ball or cylindrical roller.
It is provided with dust plug in further described screw.
Compared with prior art, this utility model is when using, by one of the first fixture or the second fixture are taken off, make on bearing, to leave one, just can ensure that the first rolling element or the second rolling element carry out reducing the operating of friction when rotating, after wearing and tearing at the rolling element used, just the fixture being fixed on bearing side can be taken off, another fixture is fixed on bearing, the rolling element stop motion originally operated can be made, another rolling element carries out reducing the operating of friction, without whole machine is stopped bearing for a long time by taking off on axle, shorten downtime, improve production efficiency.

Detailed description of the invention
Referring to figs. 1 through Fig. 4, the embodiment of this utility model double-layer rolling bearing is described further.
A kind of double-layer rolling bearing, including inner ring 1, outer ring 3 and rolling element, centre circle 2 it is additionally provided with between inner ring 1 and outer ring 3, described rolling element includes the first rolling element 5 and the second rolling element 6, described first rolling element 5 is between inner ring 1 and centre circle 2, described second rolling element 6, between centre circle 2 and outer ring 3, is provided with dismountable first fixture 7 between described inner ring 1 and centre circle 2, be provided with dismountable second fixture 8 between described centre circle 2 and outer ring 3.
When carrying out using this bearing, the axle of machine is penetrated in the axis hole 19 of bearing, the first fixture 7 between inner ring 1 and centre circle 2 is taken off, second fixture 8 remains fixed between centre circle 2 and outer ring 3, as shown in Figure 3, now inner ring 1 just can move with the first rolling element 5 of centre circle 2, start machine, axle is when rotating, axle drives inner ring 1 rotation to make inner ring 1 relatively rotate with centre circle 2, first rolling element 5 contributes for reducing friction, and centre circle 2 and outer ring 3 geo-stationary, the second rolling element 6 does not play reduction rubbing action；After the first rolling element 5 occurs to enter dust between abrasion or inner ring 1 and centre circle 2, temporarily cease machine, first fixture 7 is fixed on inner ring 1 and centre circle 2, and the second fixture 8 is taken off on outer ring 3 by centre circle 2, as shown in Figure 2, now start machine, the axle of machine drives inner ring 1 and centre circle 2 common rotation, and relatively rotate with outer ring 3, now the second rolling element 6 contributes for reducing friction, and the first rolling element 5 is without motion, the first fixture 7 and the second fixture 8 only need to be dismantled or install to whole process, without bearing is taken off by the axle of machine, operating process is easy, the saving time, improve production efficiency；The replacing to bearing is carried out again after the first rolling element 5 and the second rolling element 6 all wear and tear.
The most described first fixture 7 of the present embodiment and the second fixture 8 are annular fixing plate, the side of described inner ring 1, centre circle 2 and outer ring 3 all offers screw 31, on described annular fixing plate, corresponding screw 31 is provided with plate hole, it is equipped with bolt 76 in described plate hole and screw 31, during dismounting annular fixing plate, only need to be screwed out by screw 31 and plate hole by bolt 76, corresponding annular fixing plate is separated after screwing out by bolt 76 with bearing；When this annular fixing plate is installed, corresponding annular fixing plate is placed into bearing side correspondence position, bolt 76 through plate hole and is tightened in screw 31, just inner ring 1 can be fixed with outer ring 3 with centre circle 2 or centre circle 2 by annular fixing plate, whole operating process is without the equipment of specialty, and installing/dismounting process is easy；And annular fixing plate can carry certain weight, it is to avoid untapped first rolling element 5 or the second rolling element 6 bear weight and wear and tear in advance, increase the service life；Annular fixing plate has the effect intercepting dust simultaneously, prevents dust and impurity from entering in untapped first rolling element 5 or the second rolling element 6, it is ensured that it is the cleanest.
The preferred described bolt 76 of the present embodiment is dormant bolt 76, described annular fixing plate respective panels hole site offers counterbore, the head of described dormant bolt 76 is positioned at counterbore, when the fixed plate that changes the outfit is fixed on bearing side by dormant bolt 76, the head of dormant bolt 76 is positioned at counterbore, just can ensure that the head of dormant bolt 76 does not protrudes from annular fixing plate, annular fixing plate surfacing, it is to avoid bearing collides other objects when rotating.
It is provided with dust plug in the preferred described screw 31 of the present embodiment, when on inner ring 1, centre circle 2 or outer ring 3 without annular fixing plate, dust plug is filled in the screw 31 of corresponding exposure, enter dust in avoiding screw 31 and block, being taken out in the screw 31 filling in sky by dust plug during use, dust plug is preferably made up of rubber.
In the present embodiment, rolling element is ball or cylindrical roller.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
