Abstract
The utility model discloses high-mechanic load waterproof carrier roller sealing arrangement, it comprises axle (1) and cylindrical shell (2), in axle, be pressed with dust boot (11), between protective cover and cylindrical shell, adaptation has the bearing seat (3) in the axle of being socketed in, between one end that bearing seat contacts with dust boot and axle successively by contacting iron hoop (10), iron seal cover cap (8), inner seal ring (7) and Y shape rubber ring (9) form the first sealing, the lip of Y shape rubber ring with contact iron hoop close contact, on lip, scribble lubricating grease, bearing seat seals (4) away from one end of protective cover the end of by and contacts formation the second sealing with axle, in the axle of bearing seat inside, be arranged with tapered roller bearing (5), between tapered roller bearing and protective cover, be provided with end ring (6).The beneficial effects of the utility model are to adopt the more effectively intrusion of anti-sealing and dust of above structure, protection bearing, and annular support member can provide higher bearing load.
Description
Technical field
The utility model relates to sealing arrangement, relates in particular to high-mechanic load waterproof carrier roller sealing arrangement.
Background technology
Carrying roller is one of major part carrying on belt conveyer transmission, normally at its two ends, bearing and strut member is installed by special steel pipe, then has an axle to be fixed on support body, and belt does friction of rolling and works on carrying roller.The quality of its quality directly affects the service life of belt conveyer.Domestic current utilization widely idler structure adopts single-groove grooved bearing and non-contacting seal device, has the shortcomings such as the low and water-proofness of bearing load power is poor, when carrying roller bearing load is excessive and water inlet after cause bearing premature failure, carrying roller is low service life.
Utility model content
To be that existing idler structure is unreasonable there is the shortcomings such as the low and water-proofness of bearing load power is poor to the technical problems to be solved in the utility model, and a kind of high-mechanic load waterproof carrier roller sealing arrangement is provided for this reason.
The technical solution of the utility model is: high-mechanic load waterproof carrier roller sealing arrangement, it comprises axle and cylindrical shell, in described axle, be pressed with dust boot, between described protective cover and cylindrical shell, adaptation has the bearing seat in the axle of being socketed in, between one end that described bearing seat contacts with dust boot and axle successively by contacting iron hoop, iron seal cover cap, inner seal ring and Y shape rubber ring form the first sealing, the lip of described Y shape rubber ring with contact iron hoop close contact, on described lip, scribble lubricating grease, described bearing seat seals to contact with axle the end of by away from one end of protective cover and forms the second sealing, in the axle of described bearing seat inside, be arranged with tapered roller bearing, between described tapered roller bearing and protective cover, be provided with end ring.
The improvement of such scheme is to be provided with annular support member between the sealing of the described end and axle.
The beneficial effects of the utility model are to adopt above structure can reduce carrying roller friction drag, thoroughly completely cut off the access passage of water and dust, form the cavity of leak tightness, this structure is the intrusion of anti-sealing and dust more effectively, play the effect of protection bearing, make that this structure is suitable to be used under the condition of work under bad environment, extend the service life of carrying roller without maintenance; Annular support member can provide stronger bearing load.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram;
In figure, 1, axle, 2, cylindrical shell, 3, bearing seat, 4, end sealing, 5, tapered roller bearing, 6, shaft block ring, 7, inner seal ring, 8, iron seal cover cap, 9, Y shape rubber ring, 10, contact iron hoop, 11, dust boot, 12, annular support member.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the utility model comprises axle 1 and cylindrical shell 2, it is characterized in that being pressed with in described axle dust boot 11, between described protective cover and cylindrical shell, adaptation has the bearing seat 3 in the axle of being socketed in, between one end that described bearing seat contacts with dust boot and axle successively by contacting iron hoop 10, iron seal cover cap 8, inner seal ring 7 and Y shape rubber ring 9 form the first sealing, the lip of described Y shape rubber ring with contact iron hoop close contact, on described lip, scribble lubricating grease, described bearing seat seals 4 away from one end of protective cover the end of by and contacts formation the second sealing with axle, in the axle of described bearing seat inside, be arranged with tapered roller bearing 5, between described tapered roller bearing and protective cover, be provided with end ring 6.
When installation, bearing seat 3 is welded on cylindrical shell 2, penetrate axle 1 and be pressed into successively end sealing 4, tapered roller bearing 5, end ring 6 and by the poted assemblies having assembled (7,8,9) integral press mounting in roll body, Y shape rubber ring 9 double-contact lips are coated grease and are played lubrication and seal effect, last indentation sealing assembly two (10,11), because two poted assemblives assemble before press-fiting, save and press-fited the time.
Poted assemblies one is respectively inner seal ring, Y shape rubber ring, iron seal cover cap from inside to outside, and poted assemblies two is respectively contact iron hoop and dust boot composition from inside to outside.
In order to make carrying roller can bear higher load, can between end sealing and axle, be provided with annular support member 12, the material of annular support member is preferably elastomeric material, can improve on the one hand the sealing property of the second sealing, the impact of the radial runout power that can reduce on the other hand carrying roller on the second sealing, extends the service life of end sealing.
