Embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with the utility model
Implemented premised on technical scheme, give detailed embodiment and specific operating process, but guarantor of the present utility model
Shield scope is not limited to following embodiments.
As shown in Figure 1-Figure 3, a kind of non-contact rotary axle safeguard structure includes being sequentially sleeved at rotary shaft 3 from left to right
On anti-guard housing 1 and protective jacket 2, the anti-outer wall of guard housing 1 is stepped, and has a terrace 5, and the anti-left end external diameter of guard housing 1 is more than anti-
The right-hand member external diameter of guard housing 1, the part 4 that the anti-left end of guard housing 1 is coordinated by the connection of the first screwing bolts 10 with rotary shaft 3, anti-guard housing 1 are right
End port be provided with stretch out turn edge 6, turn edge and ring-shaped groove 7, anti-guard housing 1 formed between 6 and the terrace 5 of the outer wall of anti-guard housing 1
The bottom of terrace 5 of outer wall is provided with discharge launder 8 straight down, and the top of discharge launder 8 connection ring-shaped groove 7, the inwall of protective jacket 2 is in rank
Scalariform, the left end internal diameter of protective jacket 2 are more than the right-hand member internal diameter of protective jacket 2, and the left end port of protective jacket 2 covers the anti-right-hand member port of guard housing 1, prevent
The right-hand member of sheath 2 is fixedly connected with rotary shaft 3 by the second screwing bolts 11, and gap is left between anti-guard housing 1 and rotary shaft 3 and is prevented
Also gap is left between sheath 2 and anti-guard housing 1, i.e., anti-guard housing 1 and rotary shaft 3 and protective jacket 2 are non-contact, can't be because of rotation
Turn friction and damage, service life length.After this Standard is complete, the annulus gap of complications is formed together with rotary shaft 3, is prevented outer
Portion's solid, liquid enter.
Operation principle：Most of solid, liquid are stopped that small part can enter in ring-shaped groove 7, because of annular by protective jacket 2
The structure of groove 7 is influenceed, and solid, liquid are not easily accessible inside protective jacket 2, but can be influenceed because of gravity（See Fig. 2）, along arrow side
Discharged to the discharge launder 8 for being moved to lower section, reach the effect for preventing outer solid, liquid from entering；When rotary shaft 3 rotates,
Because being fixed with rotary shaft 3, solid, the liquid being in contact with it can be influenceed to do by centrifugal force to be moved protective jacket 2 away from axis direction,
Also hence in so that protection effect more preferably；The motor of this structure is placed in environment unshielded, being completely exposed, torn open for a period of time
After opening, solid, the liquid of outside entrance are found no.
Circumferentially be provided with annular groove 9 on the left end port inner wall of protective jacket 2, the cross sectional shape of annular groove 9 to be semicircle or
Half elliptic, on the basis of ring-shaped groove 7, increase the surface area of ring-shaped groove 7, and then increase water storage space, can be simultaneously
Exclude the ponding of more multicapacity.
Annular flange 12, the annular flange 12 and the installation slotted eye phase of part 4 are circumferentially provided with the anti-right-hand member end face of guard housing 1
Coordinate, to ensure the stabilization of the anti-installation site of guard housing 1.
This non-contact rotary axle safeguard structure, by motor actual fabrication, and empirical tests, do not wear, it is not necessary to special
Maintenance, has preferable protection effect.
