Description
Technical field
The utility model relates to motor components, and in particular to a kind of rotor.
Background technique
Motor is made of rotor and stator two parts, it is turn for realizing electric energy and mechanical energy and mechanical energy and electric energy
Changing device.Rotor is divided into motor rotor and generator amature.Rotor is the rotating part of motor, including rotor iron
The parts such as core, rotor windings and shaft.
Motor working principle is that electric energy is converted into magnetic energy (magnetic field), and two magnetic fields generate torque (angled thrust and suction
Power), operate rotor, magnetic energy is converted into mechanical energy.The effect of rotor core is exactly to give the more smoothly access of magnetic flux one, this
Access is just magnetic circuit.
Rotor core is generally made of the superposition of multi-disc silicon steel sheet, these silicon steel sheets are generally formed by mould punching, then
It covers one by one and forms rotor core in shaft.The upper silicon steel sheet of rotor core is provided with winding bore, is full of copper coil in winding bore, I
Be referred to as copper wire winding.
In the motor production process of modernization, the production process of rotor be such that produce first shaft and
Then multi-disc silicon steel punching is covered and forms rotor core in shaft by the silicon steel punching of rotor core；Finally on rotor core
Around entering copper wire winding.
Therefore the organization of production process of rotor must be carried out according to following precedence:
(1) shaft is produced first；
Then etc. (2) silicon steel stamping sheets are covered form iron core in shaft again by shafts after having produced；
(3) finally on iron core around entering copper wire winding.
The production cycle of shaft is very long, and the production process of shaft is generally divided into material heat treatment, machining, stress elimination
The processes such as heat treatment, surface treatment, these treatment processes allow shaft to have suitable rigidity, hardness and intensity
With
Wear resistance.Before shaft does not complete the production, other subsequent assembly not can be carried out.Iron core must wait
Turn
It can just be inserted in after axis finished product, since iron core is made of many pieces of silicon steel stamping sheets, it is covered one by one in shaft
Upper shape
It is quite time-consuming at iron core；Last procedure be the silicon steel punching Shangrao being superimposed enter rotor copper around
Group, together
The reason of sample, copper wire winding form iron core after the completion of must also waiting silicon steel punchings superposition to be inserted in and just can be carried out.Therefore
Motor
The time of the entire fabrication cycle of rotor is longer.
Therefore need a kind of rotor structure, this rotor structure unlike the prior art, can with multiple working procedure simultaneously into
Row, can greatly save the production cycle of rotor.
Utility model content
The purpose of this utility model is to provide a kind of motor rotor constructions to solve mentioned above in the background art ask
Topic.The technical solution of the utility model are as follows: a kind of rotor, including shaft and silicon steel stamping sheets, the four of silicon steel stamping sheets
The multiple winding bore of Zhou Kaiyou, centre bore surrounding are provided with locating slot, the silicon steel stamping sheets have it is multiple be superimposed, be superimposed
Copper wire winding is wound in the winding bore of silicon steel stamping sheets together；It further include a sleeve, the tail portion of the sleeve is equipped with one
A annular convex platform, the end vehicle of the sleeve have screw thread, and collar nut is screwed on the screw thread, the sleeve
Middle cylinder is surrounded by multiple evagination positive stop strips, and an inner wall keyway is provided on the inner hole wall of the sleeve；The shaft
Middle part is axis, one end of axis be preceding spindle nose, axis the other end be rear spindle nose, a keyway is provided on axis, in keyway
It is placed with a flat key；The sleeve is fitted on axis, is fixedly connected between sleeve and axis by flat key；The silicon steel punching
The centre bore of tabletting covers on the middle cylinder of sleeve, and the locating slot on silicon steel stamping sheets centre bore is stuck on evagination positive stop strip,
The collar nut is screwed on screw thread and is tightly pressed together silicon steel stamping sheets.
Traditional rotor is directly to wear silicon steel stamping sheets on the rotary shaft, and assembling process must be according to according to both
Fixed sequencing successively carries out.The utility model increases a sleeve, can be through on sleeve silicon steel stamping sheets in advance, then lock
The collar nut of sleeve；After shaft completes, the related silicon steel stamping sheets of sleeve can be pressed directly on the axis of shaft.By
Heat treatment is not needed in sleeve and structure is simple, and process is rapid, therefore can be in the process of shaft, synchronous processing
Sleeve simultaneously covers silicon steel stamping sheets superposition on sleeve, can also enter copper wire winding in silicon steel stamping sheets Shangrao of superposition.Shaft adds
Axis of the silicon steel stamping sheets together with sleeve indentation shaft of copper wire winding will be wound with after work using press.
Preferably, the axis is equipped with an annular stop boss, the ring of the sleeve tail portion close to one end of rear spindle nose
The annular stop boss of shape boss and axis is close together.Annular stop boss can play the work for limiting the pushed position of sleeve
With so that the pushed position of each shaft is identical.Process of press in is convenient without additionally controlling compression distance using technological means
Assembling process, also improves assembly precision.
Preferably, the key connection mode of the sleeve and axis is non-removable interference fit type.
To sum up, utility model has the advantages that
Due to increasing sleeve, the production process of shaft can with the additive processes of silicon steel stamping sheets, copper wire winding around entering
Process is synchronous to be carried out, and sleeve is directly pressed into shaft after the completion of shaft production.It compared with prior art must be in finished product shaft
On be superimposed the production methods of silicon steel stamping sheets piecewise, silicon steel stamping sheets can be superimposed, simultaneously by the utility model on sleeve in advance
And wind copper wire winding and form an entirety, this is integrally finally pressed into shaft.When therefore can save a large amount of production
Between, substantially shorten the production cycle of rotor.
