Abstract
The utility model discloses a permanent magnetism dc servomotor rotor with annular magnet steel belongs to permanent -magnet machine rotor technical field. Including rotor core, annular magnet steel and a restraint end plate, rotor core stretches out two at least bosss in the periphery epirelief at its outside end place, and the restraint end plate is equipped with two at least bosss on its periphery, annular magnet steel divides on next terminal surface be equipped with with rotor core's boss, first, two pits of boss matched with of restraint end plate, in rotor core puts into annular magnet steel's central through hole, and lucky card of its boss place in in the first pit, in above -mentioned central through hole is put into to the restraint end plate, and its boss just the card arrange in in the second pit, rotor core and restraint end plate fixed connection are in the same place. After adopting above -mentioned technical scheme, fixed connection's rotor core and restraint end plate are put on the pit that annular magnet steel both ends face was seted up through the boss card respectively, have realized that rotor core, restraint end plate and annular magnet steel's is integrative fixed.
Description
【Technical field】
The utility model is related to a kind of permanent-magnet DC electric motor rotor with annular magnetic steel, belongs to permanent-magnet DC electric motor rotor
Technical field.
【Background technology】
Annular magnetic steel is fixed most important for the normal operation of permanent magnet DC motor with being reliably connected for rotor core.
In prior art, permanent-magnet DC electric motor rotor includes annular magnetic steel, rotor core and two pieces of end plates, and there is annular magnetic steel center to lead to
Hole, rotor core is located in this central through hole, and glue is adhered to two pieces of end plates of the left and right end face of annular magnetic steel and is fixed by rivet
Rotor core, so realizes annular magnetic steel and rotor core and is integrally fixed structure.
The installation fixed structure of above-mentioned annular magnetic steel and rotor core is carefully analyzed, it is seen that the permanent magnet DC motor turns
There is following technical deficiency in son：Gluing operation interference from human factor is big, affects the stability of batch jobs, glue became uneven meeting
Affect adhesive strength, especially motor operating temperature rise can cause glue accelerated ageing with the passage of working time, when end plate with
After the adhesive strength of annular magnetic steel is reduced, when motor rotates at a high speed, end plate bears larger electromagnetic force, and annular magnetic steel with
End plate bears larger centrifugal force, and this will cause rotor core to produce relative rotation with annular magnetic steel, affects the normal work of motor
Make.In addition, glue bonding not only needs firing equipment, and glue curing needs the time to be dried, and production efficiency is low.
【Utility model content】
The technical problems to be solved in the utility model is to overcome the shortcomings of that above-mentioned prior art exists and provides one kind and exempt from
Simple for structure, the fixed reliable permanent-magnet DC electric motor rotor with annular magnetic steel of glue bonding.
To solve the above problems, the technical solution of the utility model is as follows：
A kind of permanent-magnet DC electric motor rotor with annular magnetic steel, including a rotor core and one has central through hole
Annular magnetic steel, its improvement is：Also include a restraint end plate, the periphery that the rotor core is located in its outboard end
Convex to stretch out at least two boss, the restraint end plate is provided with least two boss on its periphery, and annular magnetic steel is in one
Individual end face is provided with the first pit being engaged with the boss of rotor core, and annular magnetic steel is provided with and limit on its another end face
The second pit that the boss of moved end plate is engaged, rotor core is inserted in central through hole, and its boss is placed in described just
In one pit, restraint end plate is inserted in central through hole, and its boss is placed in second pit just, rotor core with limit
Moved end plate is fixed together.
Compared with prior art, the beneficial effects of the utility model are as follows：
After using above-mentioned technical proposal, the rotor core being fixed together and restraint end plate are respectively by respective convex
Decometer is put on the pit opened up in annular magnetic steel both ends of the surface, and the one for realizing rotor core, restraint end plate and annular magnetic steel is consolidated
It is fixed.Therefore the utility model is capable of achieving to exempt from glue bonding, and its is simple for structure, assembles simple and effective, and fixed reliability is high, works as motor
Fully meet this rotor when rotating at a high speed reliably to operate.

【Specific embodiment】
In order to be more clearly understood that technology contents of the present utility model, now lift following examples and be described in detail.
Refer to shown in Fig. 1,2,3,4,5,6, a kind of permanent-magnet DC electric motor rotor with annular magnetic steel, including one turns
Sub- iron core 1 and one have the annular magnetic steel 2 of central through hole 20, and its improvement is：Also include a restraint end plate 3, it is described
Rotor core 1 stretches out at least two boss 11 (the present embodiment is distributed evenly and at intervals the periphery that its outboard end is located is convex
Have three boss 11), the restraint end plate 3 is provided with least two boss 31 on its periphery, and (the present embodiment is evenly and at intervals
Three boss 31 are distributed with), annular magnetic steel 2 is provided with the boss with rotor core 1 on one end face (being shown in right side)
11 the first pit C11 (the present embodiment has three) being engaged, annular magnetic steel 2 is on its another end face (being shown in left side)
The the second pit C31 (the present embodiment there are three) being engaged with the boss 31 of restraint end plate 3 is provided with, rotor core 1 inserts center
In through hole 20, and its boss 11 is placed in the first pit C11 just, and restraint end plate is inserted in central through hole 20, and its
Boss 31 is placed in the second pit C31 just, and rotor core 1 is fixed together with restraint end plate 3.
In the present embodiment, rotor core 1 is fixedly connected with restraint end plate 3 by three rivets 4.
When the utility model is specifically installed, toward central through hole 20 rotor core 1, three boss of rotor core 1 are built into
11 are placed in respectively in three the first pit C11 of the right side of annular magnetic steel 2, then restraint end plate 3 are inserted into central through hole 20
Interior, three boss 31 for making restraint end plate 3 are placed in respectively in three the second pit C31 of the left side of annular magnetic steel 2, are finally
Three rivets 4 of plant, are fixedly connected rotor core 1 with restraint end plate 3.
Paste because annular magnetic steel 2, rotor core 1 and restraint end plate 3 this three exempt from glue, eliminate glue bonding
With firing equipment, just not there is a problem of yet glue need after time dry solidification and coating because motor operating temperature rise accelerates glue
The aging problem of water, and the problem of the glue became uneven of coating.
