Specific embodiment
The present invention will be further explained below with reference to the attached drawings:
As shown, the experimental rig of this hub bearing external seal air-tightness, mainly includes test seals 4, inner ring
10, outer ring 11, sealing plate 9 and ring flange 12, inner ring 10 and outer ring 11 are placed on ring flange 12, in outer ring 11 with ring flange 12
Between be equipped with test seals 4, the end face of inner ring 10 and outer ring 11 is engaged with sealing plate 9, between outer ring 11 and sealing plate 9
It is connected and fixed by pre-tightening screw rod 1, the circumferencial direction of outer ring 11 is equipped with threaded hole, and the circumferencial direction of sealing plate 9 is equipped with through-hole, in advance
The through-hole that tight screw rod 1 passes through sealing plate 9 is threadedly coupled with the threaded hole of outer ring 11.The contact of the end face of outer ring 11 and sealing plate 9
Place is equipped with end face seal I 3, and the end face of inner ring 10 and the contact position of sealing plate 9 are equipped with end face seal III 8, and inner ring 10 is located at outer ring
11 inside, the end face that inner ring 10 is contacted with sealing plate 9 are lower than the end face that outer ring 11 is contacted with sealing plate 9, and sealing plate 9 is equipped with
2 step surfaces fit with the end face seal I 3 of outer ring 11 and the end face seal III 8 of inner ring 10 respectively.It is connected on sealing plate 9
Adapter 5, sealing plate 9 are equipped with threaded hole, and the screw thread of adapter 5 is threadedly coupled with the threaded hole of sealing plate 9.Adapter 5 with
The contact position of sealing plate 9 is equipped with end face seal II 6.It is connected on the outside of adapter 5 tracheae (7), tracheae 7 is equipped with air gauge 2.
Hub bearing outer ring 11 and 10 endface of inner ring are encased inside end face seal I 3 and end face seal III 8 respectively, then cover into
