Abstract
The utility model discloses a centering roller bearing with a sealing ring, in particular relates to a centering roller bearing which is provided with a sealing ring and has sealing performance. The centering roller bearing is provided with an internal ring, an external ring and a retaining frame, wherein, the retaining frame is arranged between the internal ring and the external ring; the retaining frame consists of two punching iron retaining frames; a screening ring is arranged between the two punching iron retaining frames; bores are uniformly distributed in the circumferential direction of the punching iron retaining frames; furthermore, the bores on the two punching iron retaining frames are crossly arranged; each bore is internally provided with a spherical roller. The centering roller bearing is characterized in that ring-shaped sealing strips are arranged between two axial ends of the internal ring and the external ring. The centering roller bearing is not easy to be damaged and has long service life.
Description
Technical field
The utility model relates to a kind of roller bearing.Specifically, be the selfaligning roller bearing that has seal ring with sealability.
Background technique
At present, the various roller bearings that mechanically use all are to contain inner ring, outer ring and retainer.Retainer wherein is between inner ring and the outer ring, it is made up of two punching press iron retainers, between two punching press iron retainers middle spacer ring is arranged, they circumferentially be evenly equipped with the pocket hole, and cross-shaped layout between the pocket hole on two punching press iron retainers all has a spherical roller in each pocket hole.Because this roller bearing only is made up of inner ring, outer ring and retainer and roller, make to be open type between the axial two ends of not repaying its inner ring and outer ring.Because be open type between the axial two ends of inner ring and outer ring, outside the roller in retainer and the pocket hole thereof was exposed to, dust, foreign material and harmful gas easily entered bearing inside, bearing damages easily.Therefore, the working life of this bearing is not long.
The model utility content
Problem to be solved in the utility model is to overcome defective in the background technique, a kind of selfaligning roller bearing that has seal ring is provided.This selfaligning roller bearing, not fragile, long service life.
For addressing the above problem, take following technological scheme:
The selfaligning roller bearing that has seal ring of the present utility model contains inner ring, outer ring and retainer.Retainer wherein is between inner ring and the outer ring, it is made up of two punching press iron retainers, between two punching press iron retainers middle spacer ring is arranged, they circumferentially be evenly equipped with the pocket hole, and cross-shaped layout between the pocket hole on two punching press iron retainers all has a spherical roller in each pocket hole.Be characterized between the axial two ends of inner ring and outer ring the ring packing sheet being arranged all.
Take such scheme, have the following advantages:
Because the utility model encloses within it and the axial two ends of outer ring between be provided with the ring packing sheet, make the roller in retainer and the pocket hole thereof be sealed between inner ring and the outer ring, avoided dust, foreign material and harmful gas to enter bearing inside, make bearing not fragile, thereby prolonged the working life of bearing.
Description of drawings
Accompanying drawing is the selfaligning roller bearing structural representation that has seal ring of the present utility model.
Embodiment
As shown in drawings, the selfaligning roller bearing that has seal ring of the present utility model contains inner ring 2, outer ring 1 and retainer 3.Retainer 3 wherein is between inner ring 2 and the outer ring 1, it is made up of two punching press iron retainers, spacer ring 4 in being equipped with between two punching press iron retainers, they circumferentially be evenly equipped with the pocket hole, and cross-shaped layout between the pocket hole on two punching press iron retainers all is equipped with a spherical roller 5 in each pocket hole.In order to prevent that dust, foreign material and harmful gas from entering bearing inside, avoid the damage of bearing, prolong the working life of bearing, between the axial two ends of inner ring 2 and outer ring 1, be provided with ring packing sheet 6.This ring packing sheet is a sheet rubber.
For ease of fixing of ring packing sheet 6, on the inner side surface circumferencial direction of the axial two ends of outer ring 1, all be processed with groove, the outside of two ring packing sheets 6 embeds respectively in this two groove, and is between the outer side surface of the inside that makes two ring packing sheets 6 and inner ring 2 and contacts that shape is movable to be cooperated.
