Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Embodiment 1
Referring to Fig. 1, in the embodiment of the present invention, a kind of high-performance dust-proof machine sealing structure, including passing through gear-box 3
Rotor 1, bearing 2, tension axle sleeve 4 and outer end cap 6, the gear-box 3 are equipped with outer end cap at the position that respective rotor 1 is pierced by
6, outer end cap 6 is fixed on gear-box 3 by multiple fastening screws 1, is installed between the inner wall and rotor 1 of the gear-box 3
Have bearing 2, outer end cap 6 here has a dust reduction capability, and in order to further enhance its anti-dust performance, the rotor 1 it is outer
Portion, which is arranged with, tenses axle sleeve 4, and in order to not influence the normal rotation of rotor 1, tensing between axle sleeve 4 and rotor 1 is clearance fit,
The excircle for tensing axle sleeve 4 is equipped with a circle step 11, and step 11 is solid by the side wall of more fastening screws 28 and gear-box 3
Fixed connection, the bottom end of outer end cap 6, which is overlapped on, to be tensed on axle sleeve 4, and is equipped between tension axle sleeve 4 at the step in outer end cap 6
Sealing ring 1 is very big to reduce the situation that dust enters in outer end cap 6 and occur.
Embodiment 2
Referring to Fig. 1, on the basis of embodiment 1, the present embodiment has been made as follows in order to further enhance anti-dust performance
It improves, specific:
(1) bottom end of the outer end cap 6 is tensed filled with sealing glue between axle sleeve 4, although in height vibration and high enthusiasm
