Involved "inner" and "outside" herein, it is consistent with the inner side and outer side of carrying roller, i.e., in the axial direction, close to support
Direction inside roller is "inner", is "outside" far from the direction inside carrying roller
Please refer to attached drawing 1- Fig. 6.In a specific embodiment of the present invention, seal assembly 1 includes 11 He of outside seal
Inner seal liner 12.Outside seal 11 includes: sealing cover 110, first with cyclization 113, the first radial seal tooth 111.Inner seal liner
12 include: second with cyclization 121, the second radial seal tooth 122.The sealing cover 110 of outside seal 11 is close to the outer end of bearing block 2
Face setting.First the inside of sealing cover 110 is arranged in cyclization 113, and first is arranged with cyclization 113 in sealing cover 110 in other words
The upper side close to bearing block 2.First is interference fitted with cyclization 113 with axis 5.I.e. outside seal 11 is connected as one with axis 5.
First radial seal tooth 111 is multiple.Multiple first radial seal teeth 111 are coaxially arranged, and radially arrange.First is radial close
Sealing tooth 111 is annular.First annular seal space is formed between two neighboring first radial seal tooth 111.
Second radial seal tooth 122 be it is multiple, multiple second radial seal teeth 122 are coaxially arranged, and radially arrange.Phase
The second seal chamber is formed between adjacent two the second radial seal teeth 122.Second matches with cyclization 121 and the inner cavity interference of bearing block 2
It closes, i.e., inner seal liner 12 is linked together with bearing block 2.First one end of radial seal tooth 111 far from outside seal 11, in other words
First radial seal tooth 111 is connected in second in cyclization 121 close to one end of bearing block 2.First in outside seal 11
Radial seal tooth 111 is inserted into the second seal chamber.The second radial seal tooth 122 on inner seal liner 12 is inserted into the first sealing
In chamber.First radial seal tooth 111 and the second radial seal tooth 122 have cooperatively formed radial labyrinth sealing.
In the present embodiment, the sealing cover 110 of outside seal 11 close to bearing block 2 be arranged, for stop external impurities into
Enter in carrying roller.And the sealing of the radial labyrinth between sealing cover 110 and bearing 3 is set and prevents external impurities along sealing cover 110
Gap between bearing block 2 enters in carrying roller.In addition, since the gap between sealing cover 110 and bearing 3 can all be used to
First radial seal tooth 111 and the second radial seal tooth 122, therefore the first radial seal tooth 111 and the second radial seal are set
The axial length of tooth 122 can with long enough, then radial labyrinth sealing axial passage long enough, to improve leakproofness
Energy.
In a specific embodiment of the present invention, outside seal 11 further includes first axis sealing tooth 112.Inner seal liner
12 further include the second axial seal tooth 123.First axis seals the setting of tooth 112 first in cyclization 113, and first axis seals
Tooth 112 is also annular.Second axial seal tooth 123 is arranged on the smallest second radial seal tooth 122 of internal diameter, and second is axial close
Sealing tooth 123 also is annular.First axis sealing tooth 112 and the second axial seal tooth 123 are axially arranged, axial labyrinth is formed
Sealing.Axial labyrinth seal further provides sealing performance.
