Abstract
Keep concentric shaft coupling, lower shaft put in the shaping have lower axle sleeve centre bore, with the square jack of lower axle sleeve that lower axle sleeve centre bore leads to, the upper portion shaping of lower axle sleeve has the style of calligraphy of falling T slot, the square jack of last axle sleeve that the shaping has last axle sleeve centre bore, leads to with last axle sleeve centre bore is put in to the upper shaft, and the lower part shaping of last axle sleeve is T style of calligraphy plug tenon, in the T style of calligraphy plug tenon plug bush style of calligraphy of the falling T slot, the upper shaft plug bush is in the last axle sleeve centre bore of last axle sleeve, and the square inserted sheet plug bush of upper shaft is in the square jack of last axle sleeve, and it is together fixed with last axle sleeve that the square inserted sheet of upper shaft passes through the bolt, and the bolt passes the bolt fastening hole, in the lower axle sleeve centre bore of lower plug bush axle sleeve under, lower square inserted sheet plug bush is under in the square jack of axle sleeve, and lower square inserted sheet passes through the bolt fastening under on the axle sleeve. It can let two radical axis that link together remain throughout with one heart to improve the life of axle, avoid two radical axis to damage because of not concentric rotation.
Description
Technical field:
This utility model relates to shaft coupling technical field, can allow two more specifically to one
The axle being connected remains concentric shaft coupling.
Background technology:
Existing shaft coupling, is to be also secured on same rigid connector by two axles, when
Axle is when rotating, and two axles are not likely to rotate with one heart, so will result in axle height mill
Damage even fracture damage, thus reduce the service life of axle, the normal work of impact.Traditional
After two axles are linked together by shaft coupling, if in the case of the radial force of axle, axle is easy
Come off from shaft coupling, the normal work of impact.
Utility model content:
The purpose of this utility model is aiming at the deficiency of prior art, and provides a kind of and keep same
Heart shaft coupling, it can allow link together two axles remain concentric, thus improve axle
Service life, it is to avoid two axles are not because being to rotate with one heart and damage, meanwhile, with this practicality
When the axle of novel connection is by radial force, axle is difficult to from shaft coupling disengage.
Technology solution of the present utility model is as follows:
Keeping concentric shaft coupling, including upper shaft and lower axle, the end of upper shaft and lower axle all forms
Square inserted sheet, square inserted sheet forms bolt fixing hole；
The Lower shaft sleeve side that Lower shaft sleeve centre bore leads to is formed with Lower shaft sleeve centre bore on Lower shaft sleeve
Shape jack, the top of Lower shaft sleeve forms the font of falling T slot；
The Upper shaft sleeve side that Upper shaft sleeve centre bore leads to is formed with Upper shaft sleeve centre bore on Upper shaft sleeve
Shape jack, the bottom of Upper shaft sleeve is shaped to T font plug tenon；
In the T font plug tenon sleeve font of falling T slot, upper shaft sleeve is in the Upper shaft sleeve of Upper shaft sleeve
In central hole, the square inserted sheet sleeve of upper shaft in the square jack of Upper shaft sleeve, the square inserted sheet of upper shaft
Being fixed together with Upper shaft sleeve by bolt, bolt passes bolt fixing hole；
Lower axle sleeve in the Lower shaft sleeve centre bore of Lower shaft sleeve, the square inserted sheet sleeve of lower axle under
In the square jack of axle sleeve, the square inserted sheet of lower axle is bolted on Lower shaft sleeve.
Described on Upper shaft sleeve and Lower shaft sleeve, all form bolt head receiving space, the head of bolt
Portion is placed in this bolt head receiving space.
The beneficial effects of the utility model are:
It can allow link together two axles remain concentric, thus improves the use of axle
Life-span, it is to avoid two axles are not because being to rotate with one heart and damage, meanwhile, with this utility model even
When the axle connect is by radial force, axle is difficult to from shaft coupling disengage.
Accompanying drawing illustrates:
Fig. 1 is decomposing schematic representation of the present utility model；
Fig. 2 is the schematic perspective view of Upper shaft sleeve；
Fig. 3 is the schematic perspective view of Lower shaft sleeve；
The sectional view that Fig. 4 is Upper shaft sleeve when linking together with lower axle.
In figure: 1, upper shaft；2, lower axle；3, square inserted sheet；4, Lower shaft sleeve；5, upper shaft
Set；6, bolt head receiving space.
Detailed description of the invention:
Embodiment: as shown in Fig. 1 is to 4, keeps concentric shaft coupling, including upper shaft 1 and lower axle
2, the end of upper shaft 1 and lower axle 2 all forms square inserted sheet 3, molding on square inserted sheet 3
There is bolt fixing hole 31；
Form what Lower shaft sleeve centre bore 41 and Lower shaft sleeve centre bore 41 led on Lower shaft sleeve 4
The square jack of Lower shaft sleeve 42, the top of Lower shaft sleeve 4 forms the font of falling T slot 43；
Form what Upper shaft sleeve centre bore 51 and Upper shaft sleeve centre bore 51 led on Upper shaft sleeve 5
The square jack of Upper shaft sleeve 52, the bottom of Upper shaft sleeve 5 is shaped to T font plug tenon 53；
In the T font plug tenon 53 sleeve font of falling T slot 43, upper shaft 1 sleeve is at Upper shaft sleeve 5
Upper shaft sleeve centre bore 51 in, square inserted sheet 3 sleeve of upper shaft 1 is at the square jack of Upper shaft sleeve
In 42, the square inserted sheet 3 of upper shaft 1 is fixed together with Upper shaft sleeve 5 by bolt, bolt
Through bolt fixing hole 31；
Lower axle 2 sleeve is in the Lower shaft sleeve centre bore 41 of Lower shaft sleeve 4, and the square of lower axle 2 is inserted
Sheet 3 sleeve is in the square jack of Lower shaft sleeve 42, and the square inserted sheet 3 of lower axle 2 is solid by bolt
It is scheduled on Lower shaft sleeve 5.
Described on Upper shaft sleeve 4 and Lower shaft sleeve 5, all form bolt head receiving space 6, spiral shell
The head of bolt is placed in this bolt head receiving space 6.
Operation principle: upper shaft 1 and lower axle 2 are to be connected to one by Upper shaft sleeve 5 and Lower shaft sleeve 5
Rise, be by the T font plug tenon 53 sleeve font of falling T between Upper shaft sleeve 5 and Lower shaft sleeve 4
Slot 43 links together, between Upper shaft sleeve 5 and Lower shaft sleeve 4, there is small gap,
When upper shaft 1 rotates with lower axle 2, this small gap, it is simply that upper shaft 1 and lower axle 2
Movable adjustment space, under the upper shaft 1 effect with lower axle 2 rotator inertia, upper shaft 1 and lower axle
2 can be adjusted to one heart by nature, thus are avoided that two axles because not being to rotate with one heart and damage.
