Description
【Technical field】
The utility model is related to small-sized or micromachine, more particularly to small-sized or micromachine motor shaft and ball axle
Hold the structure of inner ring plus glue fastening.
【Background technology】
Small-sized or micromachine motor shaft is fixed together with ball bearing inner ring.
When the inner ring of motor shaft and ball bearing coordinates for gap, prior art can be in motor shaft and ball bearing
Add glue fastening between circle, the glue includes anaerobic adhesive, but motor shaft is when driving heavy load and vibrating, if glue is less
Or adding not in place, motor shaft easily slowly loosens skidding friction with the inner ring of ball bearing, so as to cause motor shaft and ball
The inner ring abrasion and heating of bearing, in the course of time, small-sized or micromachine just produces abnormal sound, and the life-span also correspondingly shortens.
If glue is excessive, glue is easily extruded to enter inside ball bearing again, and causes stuck ball bearing.
If the inner ring of motor shaft and ball bearing is interference fit, relatively difficult during ball bearing press-in motor shaft；And
And when the inner ring magnitude of interference of motor shaft and ball bearing is too big, easily cause damage to ball bearing again in process of press in.
【Utility model content】
The technical problems to be solved in the utility model is to avoid above-mentioned the deficiencies in the prior art part and provide a kind of electricity
Arbor and ball bearing inner ring add the structure and motor shaft that glue fastens, good etc. excellent with simple in construction, fixation and quality
Point.
The utility model solves the technical scheme that the technical problem uses：
The structure that a kind of motor shaft and ball bearing inner ring plus glue are fastened is provided, including motor shaft and is fixed on the motor shaft
On ball bearing；The motor shaft is at the position of the fixed ball bearing provided with least one circle groove；In the ball axle
After the inner ring held is arranged on the motor shaft, except there is glue the outer surface that the motor shaft fixes the position of the ball bearing
Outside water, also there is the glue in the groove；By the glue, the inner ring of the ball bearing is secured to the motor shaft
On.
In order that ball bearing is successfully pressed into motor shaft and does not damage ball bearing, the motor shaft and the ball axle
The inner ring held coordinates for gap.
The glue is anaerobic adhesive.
In order to fix more firm and not allow glue to flow out, the motor shaft is provided with the position of the fixed ball bearing
Three circle grooves of certain intervals distance, thus have more places to store glue.
A kind of lead-out wire protective case on micromachine is also provided；Including cylindrical type bottom and cylindrical type head, with
And the groove between the cylindrical type bottom and cylindrical type head, also through the cylindrical type bottom, groove and cylindrical type
The central through hole on head, the outer dia of the cylindrical type bottom and cylindrical type head is all higher than the outlet of the end cap of micromachine
The diameter of through hole；The lead-out wire protective case also include holding greatly the circular platform type guide part that couples with the cylindrical type head and with this
The cylindrical type insertion section of circular platform type guide part small end connection, the central through hole of the lead-out wire protective case also extends through the circular platform type
Guide part and cylindrical type insertion section；The outer dia of the cylindrical type insertion section is less than the diameter for going out line three-way hole of the end cap,
So that the cylindrical type insertion section and the line three-way hole that goes out of the end cap coordinate for gap.
Compared with the existing technology compared with the utility model motor shaft adds the structure and motor shaft of glue fastening with ball bearing inner ring
Beneficial effect be：
First, the utility model is miniature encloses groove at the position of fixed ball bearing due to motor shaft provided with least one, this
The motor shaft of structure, ball bearing be pressed into motor shaft when, the capacity of glue is sufficient, be also not in glue addition less than
The phenomenon of position so that the inner ring of motor shaft and ball bearing is fixed very firm；
2nd, because the glue of redundance can be pressed against inside each groove, glue enters ball after will not being extruded
Bearing inner and stuck ball bearing；
3rd, because the inner ring of motor shaft and ball bearing coordinates for gap, therefore ball bearing can successfully be pressed into motor
Axle, ball bearing will not also be damaged.
In summary, the utility model motor shaft has simple in construction, solid with the structure that ball bearing inner ring adds glue to fasten
Determine the advantages of firm and quality is good.

【Embodiment】
The utility model is described in further detail with reference to each accompanying drawing.
Referring to Fig. 1 to Fig. 4, a kind of motor shaft and ball bearing inner ring add the structure that glue is fastened, including motor shaft 10 and solid
It is scheduled on the ball bearing 20 on the motor shaft 10；The motor shaft 10 is provided with least one at the position of the fixed ball bearing 20
Enclose groove 11；After the inner ring of the ball bearing 20 is arranged on the motor shaft 10, except the motor shaft 10 fixes institute
Stating the outer surface at the position of ball bearing 20 has outside glue, also there is the glue 30 in the groove 11；By the glue 30,
The inner ring of the ball bearing 20 is secured on the motor shaft 10.
Referring to Fig. 1 to Fig. 4, in order that ball bearing is successfully pressed into motor shaft and does not damage ball bearing, the motor
The inner ring of axle 10 and the ball bearing 20 coordinates for gap.
The glue 30 is anaerobic adhesive.
Referring to Fig. 1 to Fig. 4, in order to fix more firm and not allow glue 30 to flow out, the motor shaft 10 is fixed described
Three circle grooves 11 of the position of ball bearing 20 provided with certain intervals distance, thus have more places to store glue
30。
Referring to Fig. 3, the utility model is before the press-in motor shaft 10 of ball bearing 20, first in the motor shaft close to groove 11
Position applies appropriate glue 30 before 10, the inner ring of ball bearing 20 then is pressed into motor shaft 10, during press-in
Glue 30 can be squeezed backward, and a part of glue 30 stays in the outer surface at the position of fixed ball bearing 20, and redundance
Glue 30 can be pressed against each the inside of groove 11.The motor shaft 10 of this structure, when ball bearing 20 is pressed into motor shaft 10, glue
30 capacity is sufficient, is also not in that glue 30 adds phenomenon not in place so that motor shaft 10 and ball bearing 20
Inner ring is fixed very firm；Because the glue 30 of redundance can be pressed against each the inside of groove 11, glue 30, which will not be extruded, to be come
After enter the inside of ball bearing 20 and stuck ball bearing；Because the inner ring of motor shaft 10 and ball bearing 20 is matched somebody with somebody for gap
Close, therefore ball bearing 20 can successfully be pressed into motor shaft 10, ball bearing 20 will not also be damaged.
Embodiment described above only expresses preferred embodiment of the present utility model, and it describes more specific and detailed,
But therefore it can not be interpreted as the limitation to the utility model the scope of the claims;It should be appreciated that for the common of this area
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In protection domain of the present utility model;Therefore, all equivalents done with the utility model right and modification,
The covering scope of the utility model claim should be belonged to.
