Description
Technical field
The utility model is related to motor shaft, especially a kind of welded hollow motor shaft.
Background technology
It is a kind of motor shaft of prior art with reference to Fig. 1, Fig. 2.In order to ensure concentricity and intensity, motor shaft generally by
Same solid bar machining is formed, and causes motor shaft heavier-weight, and allowance is big, and manufacturing cost is high；And for protective wire
Road, it is to avoid circuit winds, circuit can only be passed through be connected on motor stator by the middle part of motor shaft 1, therefore motor shaft
Tube wall need drilling formed through wires hole 1, and due to structure limit and wiring needs, the two ends of through wires hole 1 may distinguish position
In the different angles and positions of motor shaft, this must just adopt the manufacture that multistage inclines drilling to form through wires hole 1, process work
Skill is complicated, difficulty is big, and machining accuracy and working (machining) efficiency are all relatively low.
The content of the invention
In order to overcome the deficiencies in the prior art, the utility model to provide a kind of welded hollow motor shaft.
The utility model solves the technical scheme that its technical problem adopted：
A kind of welded hollow motor shaft, which is provided with through wires hole, and the motor shaft is by hollow section and linkage section welding processing
Shaping, the hollow section is hollow tube；The hollow section tube wall is provided with jack hole, in the jack hole and the hollow section
Hole connects to form the through wires hole.
The jack hole is radially arranged on the hollow section tube wall.
The hollow section is formed by welding by multistage hollow pipe.
Two hollow pipes adjacent and that internal diameter is different weld joining place, and one end of its less internal diameter is another with larger interior diameter
One end is connected by chamfering.
The linkage section is hollow tube.
The beneficial effects of the utility model are：By the way that motor shaft is divided into into hollow section and linkage section, motor shaft is not reduced
Intensity, precision while can reduce the allowance of motor shaft；And hollow section is made up of hollow tube, motor shaft is realized
Lightweight；And hollow section tube wall is provided with the jack hole connected with hollow section endoporus and forms through wires hole, processing technology is simple, carries
High working (machining) efficiency, overall manufacturing cost is greatly reduced.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of prior art；
Fig. 2 is the sectional view of prior art；
Fig. 3 is structural representation of the present utility model；
Fig. 4 is preferred embodiment of the present utility model.
Specific embodiment
With reference to Fig. 3, a kind of welded hollow motor shaft which is provided with through wires hole 1, and motor shaft is welded by hollow section 2 and linkage section 3
Reprocessing shaping after connecing, on the premise of intensity, the precision of motor shaft is not reduced, can reduce motor shaft surface adds spare time
Amount, shortens process time, improves working (machining) efficiency.
And hollow section 2 is made using hollow tube, the weight of motor shaft can be reduced, realize lightweight；And through wires hole 1
Processing technology is simple, only need to drill on the tube wall of hollow section 2 and form jack hole 11, you can connect to be formed with the endoporus of hollow section 2
Through wires hole 1, meets the arrangement requirement of motor circuit, and overall manufacturing cost is greatly reduced.
Further, jack hole 11 can be radially arranged on the tube wall of hollow section 2, and through wires hole 1 inclines drilling shape without the need for multistage
Into technique is more simple, and machining accuracy is high, low cost.
With reference to Fig. 4, according to the outside dimension of motor shaft, hollow section 2 can weld structure by the different hollow pipe 21 of multistage external diameter
Into, the allowance on motor shaft surface is further reduced, working (machining) efficiency is improved, reduce processing cost.
And for the ease of welding, two two adjacent hollow pipes 21 such as the first hollow pipe 21a and the second hollow pipe 21b, its
In the second hollow pipe 21b internal diameter be provided with it is machined after formed heavy rank 213, the first hollow pipe 21a then correspond to machine add
Work has positioning rank 211 to coordinate with heavy rank 213, makes both fit clearances meet welding requirements, while concentricity is high, nothing is obvious welding
Connect deflection；And there is difference of height in both end faces, be easy to the filling of welded seam, be finished again after having welded, it is ensured that with one heart
Degree and excircle dimension.
Simultaneously as intensity requirement, hollow pipe 21 needs to ensure certain wall thickness, i.e., interior between two adjacent hollow pipes 21
Footpath may be different, and the internal diameter joining place after its welding forms ladder wedge angle, and the end of a thread is worn and be easily obstructed when being connected to the ladder position, causes
Threading is difficult, and during follow-up bracing wire, the insulating barrier of electric wire is easily worn, damages.Therefore, can two is adjacent and internal diameter not
The welding joining place of same hollow pipe 21, one end of its less internal diameter is provided with chamfering and is connected with the other end of larger interior diameter, makes down
The largest circumference at angle is equal to the larger interior diameter of another hollow pipe 21, and electric wire worn and be just not blocked when being connected to the position, weares and teares, and assembles
It is more easy.
Further, on the premise of intensity is met, linkage section 3 also can be made up of hollow tube, further realize motor
The lightweight of axle.
The utility model is simple and reasonable, by hollow section 2 on the premise of the intensity and concentricity of motor shaft is not reduced
Machine-shaping after welding with linkage section 3, reduces allowance, realizes lightweight, and processing technology is simple, and motor shaft is greatly reduced
Manufacturing cost.
