Abstract
The utility model relates to a sealing ring rotation preventing type sealing bearing which comprises a bearing inner ring, a bearing outer ring and a steel ball, wherein a sealing ring is arranged between the bearing outer ring and the bearing inner ring, and a contact lip is arranged at the bottom of the sealing ring; and the top of the sealing ring and the bearing outer ring are fastened through a pin. The sealing ring rotation preventing type sealing bearing enhances the sealing performance of the sealing ring, prevents the sealing ring from shifting along with small particles like fine sand even under severe environment and effectively avoids slip during usage of the bearing.
Description
Technical field
The utility model relates to a kind of bearing, especially a kind of seal ring spline formula stuffing box bearing that prevents that seal ring from skidding.
Background technique
The seal ring that carries on the existing bearing, have Sealing and skeleton, the interior Zhou Yousan of Sealing the identical contact lip of thickness that is arranged in parallel, contact with the outer diametric plane of bearing inner race, the monolateral magnitude of interference of the outer diametric plane of contact lip and bearing inner race is about 0.4mm, the skeleton outer side surface has the rib of positioning seals, its closing in diameter than the big 1.0mm of bearing inner race external diameter about.This structure is for being mixed with for the bearing of working under the rugged environments such as steam, dust, silt for a long time, because small particles such as long-time silt are dry easily, driving seal ring like this when bearing working easily is shifted, thereby aggravated the wearing and tearing of bearing, finally caused the bearing shortening greatly in working life.
The model utility content
The technical problems to be solved in the utility model is: a kind of seal ring spline formula stuffing box bearing that is difficult for skidding is provided.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of seal ring spline formula stuffing box bearing, comprise bearing inner race, bearing outer ring and steel ball, be provided with seal ring between described bearing outer ring and the bearing inner race, described seal ring bottom has the contact lip; The top of described seal ring is fastening by pin and bearing outer ring.
In order to increase the lubricity of bearing, bearing outer ring described in the utility model is provided with oilhole.
The number of contact lip described in the utility model is 3.
The beneficial effects of the utility model are, solved the defective that exists in the background technique, strengthen the sealing of seal ring, made that bearing in time can be along with small particles such as fine sand be shifted in rugged environment lower seal more yet, effectively prevented bearing skidding in use.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Among the figure: 1, bearing outer ring; 2, bearing inner race; 3, steel ball; 4, seal ring; 5, contact lip; 6, oilhole; 7, pin.
Embodiment
With preferred embodiment the utility model is described in further detail by reference to the accompanying drawings now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of seal ring spline formula stuffing box bearing as shown in Figure 1 comprises bearing inner race 1, bearing outer ring 2 and steel ball 3, is provided with seal ring 4 between described bearing outer ring 1 and the bearing inner race 2, and described seal ring 4 bottoms have contact lip 5; The top of described seal ring 4 is fastening by pin 7 and bearing outer ring.
In order to increase the lubricity of bearing, bearing outer ring described in the utility model is provided with oilhole 6.
The number of contact lip 5 described in the utility model is 3.
What describe in the above specification is embodiment of the present utility model, various not illustrating is construed as limiting flesh and blood of the present utility model, the person of an ordinary skill in the technical field after having read specification can to before described embodiment make an amendment or be out of shape, and do not deviate from essence and the scope of model utility.
