Abstract
A permanent magnet motor rotor structure allowing rapid replacement of a rotating shaft comprises the rotating shaft, a rotor iron core and a permanent magnet; the rotating shaft is provided with an annular boss; a plurality of first bolt installing holes are distributed in the boss; a rotor support sleeves the front side of the annular boss of the rotating shaft; the rotor support is provided with second bolt installing holes which are matched with the first bolt installing holes respectively; the first bolt installing holes and the second bolt installing holes are locked together through a plurality of bolts so as to enable the boss to be fixedly connected with the rotor support; the outer side of the rotor support is fixedly connected with a rotor iron core; the permanent magnet is embedded in the rotor iron core. According to the permanent magnet motor rotor structure allowing the rapid replacement of the rotating shaft, the rotating shaft is fixedly connected with the rotor iron core through the bolts directly and accordingly the rotating shaft is convenient to detach and a rotor is convenient to maintain.
Description
Technical field
The present invention relates to a kind of rotor structure for permanent magnet motor, particularly a kind of rotor structure for permanent magnet motor that can quick-replaceable rotating shaft.
Background technology
Permanent magnet machine rotor comprises rotating shaft, rotor core and permanent magnet.The permanent magnetic electric machine rotor iron core of this traditional structure and rotating shaft be assembled with two kinds of modes: a kind of is that its concrete number of assembling steps is: 1. rotor punching laminates by rotor core heating and rotating shaft hot jacket are assembled; 2. rotor core heating; 3. rotor core and the assembling of rotating shaft hot jacket.Another kind is directly to connect by flat key.When machine shaft need be safeguarded because of external force deformation, rotating shaft cannot be dismantled, and can only change whole rotor.Along with constantly riseing of rare earth permanent-magnetic material price, the maintenance cost of motor is corresponding improve also.If dismounting is convenient in rotating shaft, can greatly reduce the magneto maintenance cost required because rotating shaft damages.
Summary of the invention
Technical problem to be solved by this invention is, in prior art, after rotor set installs, rotating shaft cannot be dismantled, and increased because rotating shaft damages the maintenance cost causing, and a kind of rotor structure for permanent magnet motor that can quick-replaceable rotating shaft is provided.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of rotor structure for permanent magnet motor that can quick-replaceable rotating shaft, it comprises rotating shaft, rotor core and permanent magnet, in this rotating shaft, annular boss is set, on this boss, be distributed with a plurality of the first bolt mounting holes, one rotor field spider is sheathed on the annular boss front side of this rotating shaft, and on this rotor field spider, offer the second bolt mounting holes matching with the first bolt mounting holes, a plurality of bolts are by first, two bolt mounting holes lock together to realize this boss and are fixedly connected with rotor field spider, this rotor field spider outside is fixedly connected with rotor core, on this rotor core, be embedded permanent magnet.
Further being improved to of such scheme, this first bolt mounting holes hoop is distributed on this boss.
Further being improved to of such scheme, offers a plurality of duplicate removals hole on this rotor field spider.The plurality of duplicate removal orifice ring is to being distributed on this rotor field spider.The two ends indent of this rotor field spider, to alleviate the weight of rotor field spider.
Further being improved to of such scheme, the front end of this rotor core is provided with front trim ring, and rear end is provided with back-up ring, so that rotor core is further compressed.
Further being improved to of such scheme, this bolt was coated with screw thread fastening glue before installing, and between this rotor field spider and rotating shaft, adopted interference fits.
Further being improved to of such scheme, this rotating shaft arranges this annular boss by the shaft shoulder.
Compared with prior art, beneficial effect of the present invention is:
1, the present invention, by uniform first and second bolt mounting holes of difference on the annular boss of rotating shaft and on rotor field spider, is directly connected and fixed rotating shaft and rotor core by bolt, to facilitate the dismounting of rotating shaft and the maintenance of rotor.
2, bolt of the present invention was coated with screw thread fastening glue before installing, and between rotor field spider and rotating shaft, adopted interference fits, had further facilitated the dismounting of rotating shaft and the maintenance of rotor.
3, the present invention is directly connected and fixed rotating shaft and rotor core by bolt, in rotary course, can not collect together phenomenon, if motor bearings need to overhaul also, can rotating shaft be exited to rotor from non-transmision end by unloading bolt, facilitates the replacing of bearing.
4, the present invention offers duplicate removal hole on rotor field spider, offers the comparison of duplicate removal structure with driving motor on rotor iron core lamination, and the present invention's duplicate removal on rotor field spider can not affect rotor magnetic circuit.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present invention.
In figure: 1-rotor field spider; 2-rotating shaft; 3-back-up ring; 4-rotor core; 5-front trim ring; 6-boss; The 7-the first bolt mounting holes; The 8-the second bolt mounting holes; 9-bolt; 10-shaft shoulder; 11-duplicate removal hole.
Embodiment
As shown in Figure 1, rotor structure for permanent magnet motor of the present invention comprises: 1. rotor field spider, 2. rotating shaft, 3. back-up ring, 4. rotor core, 5. front trim ring.Rotor core by silicon steel sheet punching, be overrided to form.Rotor core is as an overall structure completely mutually connecting, and mechanical strength is relatively high, easy to make.On the shaft shoulder 10 of this rotating shaft 2, annular boss 6 is set, on this boss 6, be distributed with a plurality of the first bolt mounting holes 7, rotor field spider 1 is sheathed on annular boss 6 front sides of this rotating shaft 2, and on this rotor field spider 1, offer the second bolt mounting holes 8 matching with the first bolt mounting holes 7, a plurality of bolts 9 lock together to realize being fixedly connected with of this boss 6 and rotor field spider 1 by first and second bolt mounting holes 7,8.This rotor field spider 1 outside is fixedly connected with rotor core 4, and offers a plurality of duplicate removals hole 11 on this rotor field spider 1.Bolt 9 was coated with screw thread fastening glue before installing, 2 interference fits of rotor field spider 1 and rotating shaft, and then trim ring 5, rotor core 4 before installing.After rotor core 4 installations, permanent magnet is embedded in rotor core 4, finally back-up ring 3 is pressed in rotor core 4.
