Abstract
The utility model belongs to the technical field of cylinder roller bearings, mainly relates to a three-row cylinder roller bearing axial composite cage, which is a sectional type straight pocket structure, wherein the inner diameter and the outer diameter surfaces of the cage (1) are provided with a plurality of copper blocks (2) which is used to contact with the surface of a baffle side when the cage works, and the upper and the lower end surfaces of the cage are provided with the copper blocks (2). The copper blocks (2) which are arranged on the inner diameter and the outer diameter surfaces of the cage are discontinuously arranged, and copper blocks (2) on the inner diameter and the outer diameter surface of the cage are symmetrically arranged. The three-row cylinder roller bearing axial composite cage reduces the friction of a cage steel base body and a bearing baffle side, also reduces the friction of bearing cage steel support legs and raceway surfaces at the same time, simultaneously increases the reliability of the bearing, and prolongs the service life of the bearing at the same time.
Description
Technical field
The utility model belongs to the roller bearing technical field, relates generally to a kind of three-row cylinder roller bearing shaft to composite cage.
Background technique
At present, domestic three-row cylinder roller bearing shaft has two kinds of common structures to roller cage, and a kind of is aluminium or the copper pocket hole retainer of taking turns, and a kind of is the straight pocket hole retainer that the steel tape welding connects leg, because three-row cylinder roller turntable bearing size is all bigger, so the general sectional making that adopts.These two kinds of retainers are all good the horizontal Use Limitation fruit of bearing, but when bearing vertically uses, retainer drops on the bearing edge guard naturally, the friction of external diameter and bearing edge guard is very big in the retainer, especially this class bearing substantially all is a low-speed heave-load, so between retainer and the bearing edge guard big friction is arranged all always, thereby reduces the reliability of bearing; Because the steel entity, external diameter is bigger with the rib friction in it to second kind of retainer, and its steel leg is also big with raceway frictional force, and destruction roller surface easily also, influences bearing life at shortening bearing service time.
Summary of the invention
The purpose of this utility model is to propose a kind of three-row cylinder roller bearing shaft to composite cage, retainer and the friction of rib face and the friction of steel leg and roller surface when reducing bearing and vertically using, the reliability of raising bearing.
The utility model is finished the technological scheme that its invention task taked:
A kind of three-row cylinder roller bearing shaft is the straight pocket hole structure of segmented to composite cage; The internal diameter of described retainer is provided with several copper billets with outer diametric plane, is used for making when retainer is worked set copper billet to contact with the rib surface; The upper and lower end face of described retainer is provided with copper billet, to guarantee the conformity of retainer center, pocket hole and roller centre.
Set copper billet is arranged for being interrupted on the internal diameter of retainer, outer diametric plane.
Copper billet on retainer internal diameter, the outer diametric plane is symmetrical arranged.
Copper billet on the retainer upper and lower end face is arranged for being interrupted.
A kind of three-row cylinder roller bearing shaft that the utility model proposes is to composite cage, not only reduced the friction of bearing edge guard and retainer steel base, also reduce simultaneously the friction of retainer steel leg and roller surface, when having improved the bearing reliability, prolonged the working life of bearing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A sectional drawing of Fig. 1.
Among the figure: 1, retainer, 2, copper billet.
Embodiment
With embodiment the utility model is illustrated in conjunction with the accompanying drawings:
As shown in Figure 1 and Figure 2, a kind of three-row cylinder roller bearing shaft is the straight pocket hole structure of segmented to composite cage; The matrix of composite cage 1 is a carbon steel material, and the internal diameter of retainer 1 is provided with some copper billets 2 with outer diametric plane, and the copper billet on the inside and outside diametric plane of retainer is arranged for being interrupted, and the copper billet on retainer internal diameter, the outer diametric plane is symmetrical arranged; The upper and lower end face of described composite cage is provided with copper billet 2.
During work, the copper billet on the composite cage 1 contacts with the rib surface, makes the steel base of composite cage 1 not contact with the rib surface, has reduced the friction on composite cage steel base and rib surface; When using under the operating mode of roller bearing in the vertical direction low-speed heave-load, axially composite cage 1 drops on the bearing edge guard naturally, because the utility model is provided with copper billet 2 on the surface of the interior external diameter of axial composite cage, because the friction factor of copper product is little, surfacing is again carried out with retainer in the back of copper billet welding simultaneously, can slow down axial cage and bearing edge guard frictional loss, prolong the use of bearing.
