Abstract
A stator fixing device of a permanent magnet synchronous traction machine with an outer rotor structure comprises a machine base and an annular stator fixed to the machine base. The stator fixing device is characterized in that a cylinder of a traction wheel shaft through hole is transversely arranged on the machine base, the middle of the cylinder is driven by an outer rotor, the side face, on the root portion of the cylinder, of the machine base is a perpendicular end face, an annular stator inner hole is matched with a cylindrical surface of the cylinder on the machine base, the end face of the annular stator leans against a perpendicular end face of the machine base, a plurality of through holes are evenly formed in the annular stator in the axial direction, and a plurality of screws penetrate the through holes and are fixed to screw holes in the perpendicular end face of the machine base in a screwed connection mode. Compared with the prior art, the stator fixing device has the advantages of being simple in manufacturing technology, low in cost and reliable in work.
Description
Technical field:
The present invention relates to a kind of permanent magnetic synchronous traction machine stator fixture, refer to especially outer-rotor structure permanent magnetic synchronous traction machine stator fixture, belong to elevator technology field.
Background technology
Permanent magnetic synchronous traction machine rotating speed is low, torque is large, so permanent magnetic synchronous traction machine stator will bear very large tangential force, existing outer-rotor structure permanent magnetic synchronous traction machine stator is all to connect with key conventionally, must guarantee that stator can not become flexible under electromagnetic torque effect, so, the support coordinating with stator need to be processed keyway, and stator inner hole also needs to process keyway, and needs higher symmetry, restriction due to stand structure, processing keyway is also very inconvenient, can only process with slotting machine, and slotting machine precision itself is not high, so this scheme manufacturability is bad.
Summary of the invention
The object of the present invention is to provide that a kind of manufacturing process is simple, cost is low, reliable operation
the stator fixing apparatus of outer-rotor structure permanent magnetic synchronous traction machine.
The present invention seeks to realize like this: comprise support, be fixed on the circular stator on support, its special feature is that on support, being horizontally arranged with middle is the cylinder of the traction wheel shaft perforation of external rotor drive, the support side of cylinder root is a vertical end face, circular stator inner hole coordinates with the face of cylinder of cylinder on support, circular stator faces leans against on the end face that support is vertical, the ring of circular stator be axially evenly provided with some through holes, some screws spin and are fixed on the screw of the end face that support is vertical through through hole.
beneficial effect
1 screw processing technology is simple, with drill jig, can guarantee size
2 stator faces and support have long-pending compared with large contact surface, can be very soon by stator heat conduction support.
Cylinder on 3 stators and support can adopt loose fit, when stator needs maintain and replace, because its detachability maintain and replace is more convenient, has reduced maintenance cost and for ease of maintenaince.
Accompanying drawing explanation
Fig. 1 is the structural representation of " outer-rotor structure permanent magnetic synchronous traction machine stator fixture " of the present invention;
Fig. 2 is partial sectional view of the present invention;
Fig. 3 is exploded view of the present invention (explosive view).
Sequence number explanation in figure: support 1, circular stator 2, screw 3, junction of the edges of two sheets of paper pin 4, cylinder 1a, vertical end face 1b, support screw 1c, circular stator inner hole 2a, through hole 2b, traction wheel shaft bore a hole 5.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in the figure, its structure of the present invention is mainly comprised of support 1, circular stator 2, screw 3, in the middle of being horizontally arranged with on support 1, be the cylinder 1a of the traction wheel shaft perforation 5 of external rotor drive, traction wheel shaft is arranged in traction wheel shaft perforation 5 by the bearing rotation being arranged in the perforation of traction wheel shaft, circular stator inner hole 2a coordinates with the face of cylinder of the cylinder 1a at support center, the right side end face 1b vertical with the rank of support platform contacts, and screw 3 is connected with support screw 1c through the through hole 2b of circular stator 2.
More reliable for guaranteeing stator location, the present invention is drilling between circular stator inner hole 2a and the cylinder 1a at support 1 center, beats junction of the edges of two sheets of paper pin 4, sees Fig. 2.
Here, on the vertical end face 1b of the support of the root of cylinder 1a, be provided with annular installation base 5, the screw 3 that is horizontally through circular stator 2 is screwed in annular installation base 5 circular stator 2 is fixed on annular installation base 5, the stator winding end 2a end face 1b vertical with support that like this, had both guaranteed circular stator 2 forms certain air gap.
