Abstract
The utility model discloses a seal device of a carrying idler bearing, which comprises a bearing arranged in a bearing carrier, an inner seal ring which is provided with a maze groove and fixedly arranged in the inner hole of the bearing carrier of the outside head face of the bearing, an outer seal ring which forms into a maze seal with the inner seal ring and is sleeved on the carrying idler bearing, a Z-shaped retaining ring which presses the inner seal ring into the outer ring of the bearing and arranged in the inner hole of the bearing carrier, an outer end housing fixedly arranged on the carrying carrier and positioned the outside of the Z-shaped retaining ring, and a seal ring device arranged on the Z-shaped retaining ring and the outer end housing. The seal ring device can better prevent dust and sand and water from entering into the bearing carrier. When working in the water or rainy day, the seal ring device centralizes water and obstructs water from outside. When the carrier idler is in stillness, the centralized water outflows through the outer head face. When the carrier idler is in operation, the centralized water is thrown out along the outer head face under the function of the centrifugal force, thereby achieving the purpose that the carrying idler prevents the dust and water in the abominable working environment, the service life of the carrying idler is prolonged.
Description
Technical field
The utility model relates to a kind of seal arrangement of bearing.
Background technique
At present, known carrying roller seal arrangement generally is made of inner seal ring, exterior seal ring, back-up ring and outer end cap.Be assembled to the two ends of support roller shaft at the axle two ends successively by the order of bearing, inner seal ring, exterior seal ring, back-up ring, outer end cap during assembling and be pressed in the bearing support, form flexuose labyrinth, prevent that dust and water from entering bearing.But, still there are a certain amount of sand and dust to enter into along narrow labyrinth clearance in the carrying roller at work, water is arranged in the working medium particularly or when working in the rainy day, a certain amount of water enters in the bearing along narrow labyrinth clearance inevitably, has shortened the working life of roller.
The model utility content
Technical problem to be solved in the utility model provides a kind of seal arrangement of thoroughly avoiding sand and dust and water to enter into the Idler bearing of Idler bearing.
For solving the problems of the technologies described above, the technical solution of the utility model is: the seal arrangement of Idler bearing, be installed between the roll body and support roller shaft of carrying roller, comprise the bearing support that is fixed on the described roll body inner end, be installed in the bearing in the described bearing support, the endoporus of the bearing support of the outside end face of described bearing is installed with the inner seal ring that is provided with maze trough, be arranged with the exterior seal ring that forms labyrinth seal with inner seal ring on the described support roller shaft, " Z " shape back-up ring of described inner seal ring being pressed to described bearing outer ring also is installed in the described inner hole of bearing seat, be positioned at described " Z " shape back-up ring outside on the described support roller shaft and also be installed with outer end cap, also be provided with gasket set between described " Z " shape back-up ring and the described outer end cap.
As a kind of improvement, described gasket set comprises the ring bodies that is arranged on described outer end cap inboard, " Y " shape seal ring is installed on the described ring bodies, and described " Y " shape seal ring contacts with described " Z " shape back-up ring near the edge of the wing of described " Z " shape back-up ring.
Owing to adopted technique scheme, the seal arrangement of Idler bearing, be installed between the roll body and support roller shaft of carrying roller, comprise the bearing support that is fixed on the described roll body inner end, be installed in the bearing in the described bearing support, the endoporus of the bearing support of the outside end face of described bearing is installed with the inner seal ring that is provided with maze trough, be arranged with the exterior seal ring that forms labyrinth seal with inner seal ring on the described support roller shaft, " Z " shape back-up ring of described inner seal ring being pressed to described bearing outer ring also is installed in the described inner hole of bearing seat, be positioned at described " Z " shape back-up ring outside on the described support roller shaft and also be installed with outer end cap, also be provided with gasket set between described " Z " shape back-up ring and the described outer end cap; The setting of gasket set, can better stop sand and dust and water to enter in the bearing support, when having water or rainy day to work, outside gasket set can be concentrated water and be blocked in, when carrying roller was static, concentrated water can flow out by outer end cap, during the carrying roller running, the water of concentrating also can be thrown out of at action of centrifugal force lower edge outer end cap, has thoroughly solved the purpose of carrying roller dustproof and waterproof in bad working environment, has prolonged the working life of carrying roller.
Description of drawings
Accompanying drawing is the utility model embodiment's a structural representation.
Embodiment
As shown in drawings, the seal arrangement of Idler bearing, be installed between the roll body 1 and support roller shaft 6 of carrying roller, comprise the bearing support 2 that is fixed on described roll body 1 inner end, be installed in the bearing 3 in the described bearing support 2, the endoporus of the bearing support 2 of the outside end face of described bearing 3 is installed with the inner seal ring 10 that is provided with maze trough, be arranged with the exterior seal ring 8 that forms labyrinth seal with inner seal ring 10 on the described support roller shaft 6, " Z " shape back-up ring 9 of described inner seal ring 10 being pressed to described bearing outer ring also is installed in described bearing support 2 endoporus, be positioned at described " Z " shape back-up ring 9 outsides on the described support roller shaft 6 and also be installed with outer end cap 4, also be provided with gasket set between described " Z " shape back-up ring 9 and the described outer end cap 4.
Described gasket set comprises the ring bodies 7 that is arranged on described outer end cap 4 inboards, and " Y " shape seal ring 5 is installed on the described ring bodies 7, and described " Y " shape seal ring 5 contacts with described " Z " shape back-up ring 9 near the edge of the wing of described " Z " shape back-up ring 9.The setting of " Y " shape seal ring 5, the sand and dust and the water that enter between outer end cap and the bearing support are concentrated in the groove of " Y " shape seal ring 5, when carrying roller is static, the water that concentrates on groove can flow out by outer end cap downwards along groove, during the carrying roller running, the water of groove also can be thrown out of at action of centrifugal force lower edge outer end cap, has reached the purpose of carrying roller dustproof and waterproof in bad working environment, has prolonged the working life of carrying roller.
