Fig. 1-5 is please referred to, the present invention provides a kind of technical solution:
Motor rotor component is connected to the rotor core 2 of 1 lateral wall of rotor cylinder including rotor cylinder 1, interval, vertically prolongs
Protrude into shaft 4 in the middle part of 1 inner cavity of rotor cylinder and mirror settings and the company for being fixedly connected on 1 end point of rotor cylinder
Protection mechanism 3 is connect, connection protection mechanism 3 is connected in the junction of the rotor cylinder 1 and shaft 4；The middle part on 1 top of rotor cylinder
It opens up with the axis hole 11 passed perpendicularly through for shaft 4；Connection protection mechanism 3 is turned by being movably set in 4 outer surface of shaft and being tightly attached to
Sub- 1 surface of cylinder is connected to 31 top of connecting plate and is connected in connecting plate 31 in the connecting plate 31 of cirque structure, interval to be turned
First screw 32 on sub- 1 top of cylinder is opened in the first square-shaped notch 312 of 31 lateral wall of connecting plate, is welded in this
31 top middle portion of connecting plate is simultaneously movably set in the protecting tube 33 of 4 lateral wall of shaft, through being opened in 33 lateral wall of protecting tube
Second notch 331, the reinforcing for being sheathed on 33 lateral wall of protecting tube and protecting tube 33 being held on to the " U "-shaped structure of 4 outer wall of shaft
Ring 34 is connected in 34 lateral wall of reinforcing ring and reinforcing ring 34 is connected in the second screw 35 of 4 lateral wall of shaft and vertical is inserted
Enter in the first notch 312 and be connected in the rectangular limited block 36 in 1 top of rotor cylinder by screw to constitute；Second screw
35 one end extends into the second notch 331 and is fixedly linked with the lateral wall of shaft 4；Ring body one end of reinforcing ring 34 is fixed with
One convex block 341, the ring body other end of reinforcing ring 34 are fixed with the second convex block 342 with 341 flush of the first convex block, the first convex block
341 and second convex block 342 side between be connected with bolt 343, the side of the first convex block 341 and the second convex block 342 is run through
It offers and is passed through for bolt 343 and slide opening 3411 that shape is rectangular.
The middle part perforation on 31 top of connecting plate offers the perforation 311 passed perpendicularly through for shaft 4, the inner hole of the perforation 311
Wall is in contact with the outer axis body of shaft 4.
The side view shape of first convex block 341 and the second convex block 342 is rectangular configuration, first convex block 341 and second convex
The whole size of block 342 is identical；3411 left side of slide opening of the first convex block 341 is extended in the stud left end of bolt 343, and stud is left
End, which is welded with, determines nut；The stud right end of bolt 343 extends 3411 right side of slide opening of the second convex block 342, and the right end of stud
It is threaded with traveling nut；The stud of bolt 343 is artificially slided along the length direction of slide opening 3411.
Non-slip groove is distributed in the inner tubal wall of protecting tube 33 location interval that is in contact with 4 lateral wall of shaft, which cuts
Face shape is in " S " shape wavy shaped configuration；The setting of non-slip groove is capable of increasing the degree of roughness of 33 inner tubal wall of protecting tube, increases protection
The frictional force of 33 inner tubal wall of pipe, enables protecting tube 33 to clench the outer wall of shaft 4, is easy to use protecting tube 33 to shaft
4 carry out reinforcement processing with 1 junction of rotor cylinder.
The present invention can form in shaft 4 and 1 junction of rotor cylinder by the connection protection mechanism 3 of setting and reinforce knot
Shaft 4, connecting plate 41 and rotor cylinder 1 are firmly fixed on one by structure, so that the motor rotor component is when used for a long time,
Shaft 4 and rotor cylinder 1 are bonded always in one, effectively prevent occurring shaft 4 when in use being separated with rotor cylinder 1
The case where influencing motor rotor component normal use, while can be using protecting tube 33 and connecting plate 31, in shaft 4 and rotor post
1 junction of body forms protection structure, carries out enclosing protection to shaft 4 and 1 junction of rotor cylinder, reduces the motor rotor component
Shaft 4 and 1 top junction of rotor cylinder occur fractureing the probability of rupture event when in use, to be conducive to the rotor
The popularization and use of component.
Working principle: in use, the top that connecting plate 31 is connected in rotor cylinder 1 by the first screw 32 is advanced with, this
When 31 top of connecting plate perforation 311 and 1 top of rotor cylinder axis hole 11 it is vertically opposite and be mutually communicated, limited block 36 is vertical
It is placed in the first notch 312, and limited block 36 is connected in the top of rotor cylinder 1 using screw；Then by protecting tube
33 are vertically welded in the top middle portion of connecting plate 31, and reinforcing ring 34 is set in the outer tube wall of protecting tube 33, then successively by shaft 4
It is inserted perpendicularly into 33 inner cavity of protecting tube, perforation 311 and axis hole 11, recycles reinforcing ring 34 to be firmly clamped in protecting tube 33 at this time
The work of shaft 4 and the installation of rotor cylinder 1 is completed in the outer surface of shaft 4；Finally by the rotor core of motor rotor component
2, rotor windings are placed on rotor cylinder 1, complete the installation of motor rotor component, and rotor core 2, rotor windings are mounted on
Method on rotor is common method in the market, and and therefore not to repeat here.
Wherein, the second screw 35 of 34 ring body side of reinforcing ring need to protrude into the second notch 331 in advance, by reinforcing ring 34 and turn
4 stationary phase of axis is connected；Protecting tube 33 is firmly clamped in shaft 4 using reinforcing ring 34, to play reinforcing to shaft 4
Purpose, reducing the motor rotor component, there is the rupture event that fractures in shaft 4 and 1 top junction of rotor cylinder when in use
Probability prevents occurring the case where shaft 4 separates influence motor rotor component normal use with 1 phase of rotor cylinder when in use.
The reinforcing step of reinforcing ring 34 are as follows: user uses the second screw 35 first, by 34 middle section of reinforcing ring and shaft 4
Axis body stationary phase is connected, then moves position of the bolt 343 in slide opening 3411；When bolt 343 is located proximate to protecting tube 33
When outer tube wall, the traveling nut of rotating bolt 343 drives the second convex block 342 to continue close to the first convex block 341, in the second convex block
342 continue during to the first convex block 341, and the interior annular aperture of reinforcing ring 34 persistently reduces and generates chucking power, drives
33 caliber of protecting tube persistently reduces and generates chucking power, and protecting tube 33 is tightly clamped in shaft 4, and then reinforcing ring 34 is to anti-
Pillar 33 plays clamping effect, so that protecting tube 33 and shaft 4 are firmly held on one, when 343 position of bolt is far from protecting tube
When 33 outer tube wall, reinforcing ring 34 no longer clamps protecting tube 33, so that protecting tube 33 is no longer clamped shaft 4.
The transverse width of limited block 36 is equal with the transverse width of the first notch 312 in the present invention, to allow limited block 36
Lateral wall tightly fit in the inner wall of the first notch 312, be conducive to limited block 36 and connecting plate 31 limited, prevent from turning
Connecting plate 31 facilitates the use of the motor rotor component the case where 1 top of rotor cylinder is subjected to displacement when axis 4 uses.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
