Preferably, further include spacing card, which is connected to bearing housing by screw D, while the spacing card end is inserted
In the annular groove for entering drive sleeve front.
Preferably, the drive sleeve rear end is fastening part, which is more than front end, and in the fastening part
Groove is offered, through-hole and threaded blind hole are respectively arranged at left and right sides of the groove, the through-hole and blind hole are used for screw
B, and drive sleeve is anchored on by rotary shaft by screw B.
Preferably, the straight slot of the axle sleeve rear end, width and length are all higher than the width and length of key.
The utility model has the advantages that：
The utility model is designed reasonably, it is simple in structure, it is easy to use, mechanical seal bearing can be avoided to the maximum extent
Damage, can there is certain displacement between drive sleeve and axle sleeve so that when play occurs for rotary shaft, axle sleeve will not be with rotary shaft
Mobile, only drive sleeve is moved with rotary shaft；
By rationally designing key, key is connect by screw with drive sleeve, then key is put into the straight slot of axle sleeve, ensure axis
Set is rotated with drive sleeve, when play up and down occurs for rotary shaft, drive sleeve tightening on the rotary shaft, with movement, axle sleeve due to
Bearing positions, and the movement without axial direction occurs keeps its sealing effect more preferable, use the longevity to protect mechanical seal
It orders longer；
By improving, the utility model can protect the bearing of mechanical seal, when extending the use of bearing to greatest extent
Between, the service life of mechanical seal is extended, simultaneously as being packaging type, does not have to site installation test, is easily installed, structure letter
Single, significant effect is worthy to be popularized.

Specific implementation mode
The utility model is described in detail below in conjunction with attached drawing 1- Fig. 2, to the skill in the utility model embodiment
Art scheme is clearly and completely described, it is clear that and the described embodiments are only a part of the embodiments of the utility model, and
The embodiment being not all of.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creativeness
The every other embodiment obtained under the premise of labour, shall fall within the protection scope of the present invention.
As Figure 1-Figure 2, the utility model provides a kind of mechanical seal bearing protection formula drive mechanism herein, including
It is installed on the axle sleeve 1 of rotary shaft 8, which is provided with straight slot；
The key 3 being installed in 1 straight slot of axle sleeve；And
Drive sleeve 2,2 front end of drive sleeve are connect by screw A4 with key 3, and are also set up in the 2 front outer circle of drive sleeve
Annular groove.
Further include spacing card 5, this is fixed according to a kind of mechanical seal bearing protection formula drive mechanism described in the utility model
Bearing housing 11 is connected to by screw D6 away from card 5, while 5 end of spacing card is inserted into the annular groove of 2 front of drive sleeve.
According to a kind of mechanical seal bearing protection formula drive mechanism described in the utility model, 2 rear end of the drive sleeve is
Fastening part, which is more than front end so far, and offers groove 2.1 in the fastening part, in the groove 2.1 or so two
Side is respectively arranged with through-hole and threaded blind hole, and the through-hole and blind hole are used for screw B7, and by screw B7 by drive sleeve 2
It is anchored on rotary shaft 8.
According to a kind of mechanical seal bearing protection formula drive mechanism described in the utility model, 1 rear end of the axle sleeve leads to
Slot, width and length are all higher than the width and length of key 3.
The utility model specific implementation is as follows：
When it is implemented, paying attention to design key 3 and leading to the length fit dimension of keyway on axle sleeve 1, design transportable
Distance is fixed by spacing card 5；The processing of drive sleeve 2 is somewhat more complex, is integrated with positioning, holds a variety of work(such as transmission tightly
Can, therefore it is concentric to should be noted that the processing at 2.1 both ends of groove needs when processing.In actual use, key 3 is put into the logical keyway of axle sleeve 1
It is interior, by drive sleeve 2 be packed into axle sleeve 1, pays attention to 2 nose threads hole of drive sleeve is corresponding with key through-hole, with screw A4 by key 3 and be driven
2 connection of set；Spacing card 5 is put into 2 front end annular groove of drive sleeve, notices that the direction of spacing card 5 should not be anti-loaded, with screw D6 by spacing
Card 5 is connect with bearing housing 11, and thus collection installs.Spacing card quantity is uniformly distributed as required.
After machine envelope and the utility model are packed into rotary shaft 8 at the scene, this integrated mechanical sealing is consolidated with screw C12
After being scheduled in equipment, screw B7 is tightened, drive sleeve 2 is held tightly in rotary shaft 8；Screw D6 is finally unclamped, spacing card 5, peace are removed
Dress up work(；Drive sleeve 2 holds rotary shaft 8 tightly with rotation, and key 3 drives axle sleeve 1 to rotate, mechanical seal normal work；When equipment goes out
Now abnormal, play occurs for rotary shaft 8, and drive sleeve 2 is moved together with rotary shaft 8, and key 3 leads to also with moving together in axle sleeve 1
It is moved in slot, and axle sleeve 1 can't be moved since bearing 9 positions, in this way, bearing 9 would not be outer by what should not be born
Power and cause premature breakdown；It ensure that the service life of mechanical seal to greatest extent.
The utility model is designed reasonably, it is simple in structure, it is easy to use, mechanical seal bearing can be avoided to the maximum extent
Damage, can there is certain displacement between drive sleeve and axle sleeve so that when play occurs for rotary shaft, axle sleeve will not be with rotary shaft
Mobile, only drive sleeve is moved with rotary shaft；
By rationally designing key, key is connect by screw with drive sleeve, then key is put into the straight slot of axle sleeve, ensure axis
Set is rotated with drive sleeve, when play up and down occurs for rotary shaft, drive sleeve tightening on the rotary shaft, with movement, axle sleeve due to
Bearing positions, and the movement without axial direction occurs keeps its sealing effect more preferable, use the longevity to protect mechanical seal
It orders longer；
By improving, the utility model can protect the bearing of mechanical seal, when extending the use of bearing to greatest extent
Between, the service life of mechanical seal is extended, simultaneously as being packaging type, does not have to site installation test, is easily installed, structure letter
Single, significant effect is worthy to be popularized.
