Description
Technical field
The invention belongs to hydraulic generator yoke technical field.
Background technology
The hydraulic generator yoke generally adopts solid yoke and stacked yoke.Solid yoke generally is used for the high speed small-capacity generator, with rotating shaft monobloc forging or hot jacket in rotating shaft, Surface Machining has the dove tail to be used for fixing magnetic pole.The solid yoke that the small size generator adopts because rotor is not very heavy, does not need large-scale tool and mould and large-scale punching.And in the large scale generator, adopt solid yoke can make rotor very heavy, and dovetail slot needs special milling head processing, and work efficiency is low and milling head is fragile, the processing cost height, therefore, the large scale generator adopts stacked yoke usually.Stacked yoke be with one group of overlapping hot jacket of magnet yoke ring on the rotor field spider in the rotating shaft, outer round surface is processed with the T tail and is used for fixing magnetic pole, its rotor weight is light, but its T tail need be made large-scale punch die and use the punching out of large-tonnage punch press, processing cost is still very high, and the yoke strength and stiffness are poor, and trouble is installed.
Summary of the invention
Purpose of the present invention provides a kind of large scale generator that is used for for the deficiency that solves above-mentioned prior art existence just, does not need large-scale tool and mould and large-tonnage punch press processing T tail, the low and easy-to-install bracket type solid magnet yoke of water-wheel generator of processing cost.
The objective of the invention is to be achieved through the following technical solutions.
Bracket type solid magnet yoke of water-wheel generator comprises hub-type rotor field spider in rotating shaft of rotating shaft, hot jacket, is set in the yoke outside the described rotor field spider; Described rotor field spider is uniformly distributed along the circumference and is provided with at least 4 support arms, and the rotor field spider outer round surface in corresponding support arm position is processed with first keyway; Described yoke is made up of one group of coaxial magnet yoke ring that stacks, correspondingly with support arm in magnet yoke ring be provided with the stud that one group of inner surface is processed with second keyway, between per two magnet yoke rings that stack, be provided with the septal branch bracer, be outside equipped with wind deflector at each septal branch bracer; Between first keyway and second keyway, be fitted with taper key.
The support arm of described rotor field spider has 6 ~ 8.Yoke is made up of 3 ~ 6 coaxial magnet yoke rings that stack.First keyway and second keyway are the wedged bottom keyway.Cover plate is equipped with at two ends at taper key.Spacing between per two magnet yoke rings that stack is 50mm.Rotor field spider outer round surface in corresponding support arm position is processed with boss, and first keyway is machined on the boss.Described septal branch bracer is trapezoidal back-up block, and it is the outside V-arrangement of opening that correspondence is arranged on the outer wind deflector of each septal branch bracer.Stud is welded in the magnet yoke ring.
The present invention need not large-scale tool and mould and large-scale punching can be processed T tail or dove tail on magnet yoke ring, obviously reduce the generator manufacturing cost, both draw the lightweight advantage of stacked yoke, possessed the low advantage of solid yoke dove tail processing cost again, be specially adapted to the large scale generator.
Further set forth content of the present invention below in conjunction with Figure of description.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
As shown in the figure, the present invention includes rotating shaft 3, hub-type rotor field spider 2, be set in the outer yoke 1 of rotor field spider.Rotor field spider is uniformly distributed along the circumference and is provided with at least 4 support arm 2a, and preferred 6 ~ 8, present embodiment is symmetrically arranged 6.Rotor field spider cylindrical 2b surface in the support arm outer end is processed with the first keyway 2c.Can take to process boss earlier, again the processing first keyway 2c on boss at the rotor field spider outer round surface.Yoke 1 is made up of one group of coaxial magnet yoke ring that stacks, and generally adopts 3 ~ 6 coaxial magnet yoke rings that stack to stack the composition yoke, and the spacing between per two magnet yoke rings that stack is 50mm.Magnet yoke ring is cast steel ring or forged steel ring.The position corresponding with the support arm 2a of rotor field spider in magnet yoke ring is provided with the stud 5 that one group of inner surface is processed with the second keyway 5a.Support arm 2a, the first keyway 2c, the second keyway 5a, stud 5 quantity are identical.Rotor field spider boss and stud make yoke that axial restraint be arranged and can generation not move axially when operation.Separate as the radial ventilation ditch with back-up block 8 between per two magnet yoke rings that stack, in conjunction with being arranged on the outer wind deflector 7 of each septal branch bracer, cooling air can smooth and easy Radial Flow when making operation.Present embodiment septal branch bracer 8 is trapezoidal back-up block, and correspondence is arranged on each septal branch bracer outer wind deflector 7 and is the outside V-arrangement of opening.The first keyway 2c and the second keyway 5a all are processed as the wedged bottom keyway.During assembling, with rotor field spider 2 hot jackets in rotating shaft 3, the relative back integral body that combines with the first keyway 2c on the rotor field spider of the second keyway 5a on the stud 5 is hung in circle in the yoke 1, insert between first keyway and second keyway taper key 4 also urgent again behind the location, rotor field spider and yoke are fused, then stud and magnet yoke ring are welded.Cut the taper key that exceeds end face, the cover plate 6 of burn-oning again prevents in when hypervelocity operation yoke to swell circle taper key does not have pressure and loosening falling down.The taper key of the present invention and first keyway and second keyway adopt precision-fit, by the shearing to taper key moment of torsion are passed to yoke during operation, and magnet yoke ring expansion rear magnetic yoke still can be located when overrunning in the running simultaneously, can reset fully after the deceleration.Yoke assembling simultaneously also need not be heated, and the support yoke did not break away from when keystroke guaranteed to overrun again after yoke is expanded, and installment work is simple.Stud be again with rotor field spider on first keyway pairing after be soldered to again on the yoke, to the positional precision of keyway on support high request too not, easy to process.
The present invention promptly can adopt conventional tool and mould and punch press to yoke side of milling and processing dovetail slot after having beaten taper key 4, promptly can dispatch from the factory then.Can select whole Transporting or unclamp taper key to split out separately transportation of rotor field spider according to transportation condition.The present invention alleviates rotor weight, and processing is simple, low cost of manufacture.
