Abstract
Assembled bearing roller sealing device relates to the auxiliary equipment of bearing roller, especially relates to a assembled bearing roller sealing device. Including outer seal (1), sealing ring (2), inner sealing piece (3), its characterized in that, outer seal (1) be provided with hollow assembly post (11), inner sealing piece (3) be provided with with assembly intermediate layer (31) of assembling post (11) looks adaptation, the one end opening of assembly intermediate layer (31), the other end is sealed, sealing ring (2) and assembly intermediate layer (31) looks adaptation, the utility model discloses can improve the quality of bearing roller, increase the life of bearing roller, simple structure, convenient to use's positive effect.
Description
Technical field
The utility model is related to the auxiliary equipment of carrying roller, more particularly to a kind of assembled carrier roller sealing device.
Background technology
Carrying roller is the vitals of ribbon conveyer, and species is more, and quantity is big.It account for the 35% of a ribbon conveyer totle drilling cost, generate more than 70% resistance, therefore the quality of carrying roller is particularly important.Seal ring for carrier rollers not only can prevent working media from leaking, and be also prevented from the immersion work internal body such as mud, dust, water, the damage of Idler bearing be caused, so as to affect the quality and service life of carrying roller.At present, domestic seal ring for carrier rollers is mostly labyrinth sealing, is the sealing means using blocking airflow.This seal ring for carrier rollers causes the rotational resistance of carrying roller big because seal clearance is little, the sealing number of teeth.
The content of the invention
The purpose of this utility model is to provide a kind of assembled carrier roller sealing device, and suitable to reach seal clearance, Idler bearing is not corroded by extraneous medium, and the rotational resistance of carrying roller is less, it is possible to increase the quality of carrying roller, increase the service life of carrying roller, simple structure, purpose easy to use.
Assembled carrier roller sealing device provided by the utility model, including outside seal, sealing ring, inner seal liner, it is characterised in that described outside seal is provided with hollow assembling post, inner seal liner is provided with the assembling interlayer being adapted with assembling post；The one end open of described assembling interlayer, other end sealing；The sealing ring is adapted with assembling interlayer.
Assembled carrier roller sealing device provided by the utility model, sealing ring is placed on the assembling interlayer sealed end of inner seal liner, and outside seal is assembled post and is coupled from the assembling interlayer openend of inner seal liner.Outside seal can isolate supporting roller bearing seat outer with extraneous medium, so as to realize the sealing of supporting roller bearing seat outer；Inner seal liner can isolate Idler bearing with extraneous medium, so as to realize the sealing of Idler bearing；The planar line contact slide friction of the arc surface of sealing ring and the plane of inner seal liner, outside seal, had not only realized sealing effectiveness but also can reach that coefficient of friction is minimum, the reduction of the frictional contact surface of assembled carrier roller sealing device, the rotational resistance of carrying roller accordingly reduces.Therefore, the utility model has seal clearance suitable, and Idler bearing is not corroded by extraneous medium, and the rotational resistance of carrying roller is less, it is possible to increase the quality of carrying roller, increases the service life of carrying roller, simple structure, good effect easy to use.
Description of the drawings
Accompanying drawing part discloses the utility model specific embodiment, wherein,
Fig. 1, Standard figure of the present utility model；
Fig. 2, the structural representation of outside seal of the present utility model；
Fig. 3, the structural representation of sealing ring of the present utility model；
Fig. 4, the structural representation of inner seal liner of the present utility model.
Specific embodiment
As shown in Figure 1,2,3, 4, assembled carrier roller sealing device provided by the utility model, including outside seal 1, sealing ring 2, inner seal liner 3, outside seal 1 is provided with hollow assembling post 11, and inner seal liner 3 is provided with the assembling interlayer 31 being adapted with assembling post 11；The one end open of described assembling interlayer 31, other end sealing；The sealing ring 2 is adapted with assembling interlayer 31.
The utility model when in use, first, from the openend of the assembling interlayer 31 of inner seal liner 3, sealing ring 2 is put into the sealed end of assembling interlayer 31；Then, from the openend of the assembling interlayer 31 of inner seal liner 3, the assembling post 11 of outside seal 1 is put into into assembling interlayer 31, extruding outside seal 1 and inner seal liner 3, the top for making assembling post 11 contacts with the sealing ring 2 in assembling interlayer 31, and outside seal 1, sealing ring 2, inner seal liner 3 are assembled into one；Finally, by the outside seal 1 of assembling one, sealing ring 2, inner seal liner 3 along the hollow bearing for being set in carrying roller of assembling post 11, the inflated diameter of assembling post 11 is consistent with the bearing diameter of carrying roller, the sealed end of assembling interlayer 31 is located at the outside of Idler bearing, the openend of assembling interlayer 31 is located at the inner side of Idler bearing, the inner side of assembling post 11 is in close contact with the bearing of carrying roller, the outside of outside seal 1 is in close contact with carrying roller, so as to Idler bearing be isolated with extraneous medium, reduce the rotational resistance of carrying roller.
The outside of above-mentioned inner seal liner 3 is provided with two symmetrical sealing flanks 32.Sealing flank 32 is symmetrical, can make the both sides stress of Idler bearing, and such as frictional force is consistent, reduces the rotational resistance of carrying roller, it is possible to increase the quality of carrying roller, increases the service life of carrying roller.
Above-mentioned sealing flank 32 is Mitsubishi's cylindricality, and the height for sealing flank 32 is highly identical with inner seal liner 3, and seal clearance is suitable, can effectively be stopped in the immersion carrying roller such as extraneous mud, dust, water, Idler bearing is not corroded by extraneous medium.
