Description
Technical field
This utility model belongs to sealing protection technical field and in particular to a kind of efficient sealed rotational structure.
Background technology
At present for almost all of motor type product, due to there is rotary shaft, therefore difficult to realize efficiently dust-proof anti-
Water effect.Thereby result in auxiliary products affected by environment very big, cause the equipment cannot be normal in heavy showers snowy day gas, dust atmosphere
Use, so not only have a strong impact on the production capacity of equipment, and economic loss can be caused in fault.
Utility model content
The purpose of this utility model is to provide a kind of efficient sealed rotational structure, solves there is rotary shaft in prior art
The not good problem of device sealing effectiveness.
This utility model be employed technical scheme comprise that：A kind of efficient sealed rotational structure, including rotary shaft, rotary shaft
For multidiameter, rotary shaft is outer to be socketed with retaining collar, the collar and seal ring from its big end successively to small end；The axis hole of retaining collar sets
It is equipped with labyrinth oil seal groove for forming labyrinth seal and rotary shaft between；Pass through lip-type packing between rotary shaft and retaining collar
Sealed；The outer end of the collar has a through hole, and the outer end of retaining collar has a blind hole coaxial with this through hole, the through hole of the collar and
Securing member is installed in the blind hole of retaining collar, is sealed by O-ring seal between retaining collar and the collar；The collar and envelope
Sealed by the form of labyrinth seal between ring；Seal ring and rotary shaft are interference fit.
A kind of feature of efficient sealed rotational structure of this utility model also resides in：
The outer face of seal ring offers tapped blind hole.
Lip-type packing is the secondary bead structure of band.
The beneficial effects of the utility model are：This utility model be completely suitable for motor product in the market and its
He has the equipment of rotary shaft, and it can strengthen product hermeticity energy, strengthens the dustproof and waterproof effect of product, to adapt to severe
Environment, simultaneously with low cost, in the case of not affecting motor production cost, improve the serviceability of product, and then improve
The environmental suitability of corollary equipment, improves industry production capacity, reduces rate of breakdown, reduces economic loss.
Brief description
Fig. 1 is a kind of structural representation of efficient sealed rotational structure of this utility model.
In figure, 1. rotary shaft, 2. lip-type packing, 3.O type sealing ring, 4. retaining collar, the 5. collar, 6. securing member, 7.
Seal ring.
Specific embodiment
With specific embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings：
A kind of efficient sealed rotational structure of this utility model, as shown in figure 1, including rotary shaft 1, rotary shaft 1 is ladder
Axle, rotary shaft 1 is outer to be socketed with retaining collar 4, the collar 5 and seal ring 7 successively from its big end to small end；The axis hole of retaining collar 4 sets
It is equipped with labyrinth oil seal groove for forming labyrinth seal and rotary shaft 1 between；Pass through lip close between rotary shaft 1 and retaining collar 4
Seal 2 is sealed；The outer end of the collar 5 has through hole, and the outer end of retaining collar 4 has the blind hole coaxial with this through hole, the collar 5
Through hole and retaining collar 4 blind hole in securing member 6 is installed, carried out by O-ring seal 3 between retaining collar 4 and the collar 5
Sealing；Sealed by the form of labyrinth seal between the collar 5 and seal ring 7；Seal ring 7 and rotary shaft 1 are interference fit.Seal ring
7 outer face offers tapped blind hole.Lip-type packing 2 is the secondary bead structure of band.
This utility model makes rotary shaft 1 reach efficient double sealing using lip-type packing 2, seal ring 7.Rotary shaft 1 with solid
Determine rotating part and standing part that the collar 4 is respectively product, certainly exist gap between the two, this utility model is exactly to make two
Realize sealing between person, reach efficient dustproof and waterproof effect.Lip-type packing 2 is the secondary bead structure of band, well protects outside powder
Dirt and liquid pass through the gap entrance cavity between rotary shaft 1 and retaining collar 4；Using fastening between retaining collar 4 and the collar 5
Part 6 fastening is installed, and using blind hole, and is sealed with O-ring seal 3, and good protection external dust passes through fixed cover with liquid
Gap between ring 4 and the collar 5 enters cavity；The collar 5 and seal ring 7 adopt labyrinth seal, and seal ring 7 and rotary shaft 1 adopt interference
Cooperation, hot jacket is installed, and groove is staggered to form labyrinth, and effectively protection external dust is externally entering cavity, seal ring 7 outer end with liquid
Face increases tapped blind hole, in the case of ensureing sealing, easy to disassemble；Retaining collar 4 axis hole increases labyrinth oil seal groove, with rotation
Form labyrinth, effectively protection inner chamber lubricant grease is revealed between axle 1.
