Abstract
The invention discloses an air gap adjustable permanent magnet motor, which comprises a stator, a rotor, an outer ring of a main bearing, an inner ring of the main bearing, and a conical support. The outer ring of the main bearing is connected with a connecting flange disk positioned on the right side through a bolt II. A through hole I is formed at the periphery of the connecting flange disk in the circumferential direction. A through hole II which has the same radial position as the through hole I is formed on the rotor support. The rotor support and the connecting flange disk are connected together through a bolt III which is arranged in the through hole I and the through hole II. At least two wedged bosses are uniformly distributed at the periphery of the connecting flange disk. The wedged bosses are provided with at least two screwed holes I and provided with a tapered wedge. At least two through holes III and at least two screwed holes II are formed on the tapered wedge. A bolt IV is arranged in the screwed hole I through the through hole III, and a bolt V supports the wedged bosses through the screwed holes II. Through the air gap adjustable permanent magnet motor, an air gap can be conveniently and quickly adjusted.
Description
Technical field
The present invention relates to a kind of magneto, especially relate to a kind of air gap adjustable permanent magnet motor.
Background technology
Compare with electric excitation, the efficient of magneto is higher, is used widely because of it need not excitation unit.But there is the problem of assembling difficulty in magneto, in the time of particularly need adjusting the air gap uniformity between stator and rotor, its assembly manipulation process more bothers, must be earlier during assembling with stator, rotor fastening good after the uniformity of air gap between energy measurement stator and rotor, if air gap can not meet design requirement, fastening bolt must be unclamped, readjust the relative position between stator and rotor, treat that relative position adjusts, after fastening bolt tightened, measure the air gap between stator and rotor once more, so repeatedly, the air gap until between stator and rotor meets design requirement.Along with the continuous increase of power of motor, used fastening bolt is also increasing, twists a Bolt Torque and wants 2-3 hour, if motor regulating the qi flowing in the channels crack is several times repeatedly assembled a motor so and spent 1-2 days time possibly, operating efficiency is extremely low.
Summary of the invention
The objective of the invention is to overcome the above-mentioned defective that prior art exists, provide a kind of air gap air gap adjustable permanent magnet motor fast easy to adjust.
Technical scheme of the present invention is: it comprises stator, stator support, rotor, rotor supports, the base bearing outer ring, the base bearing inner ring, taper is supported, described stator and stator support are connected, rotor and rotor supports are connected, taper is supported the big end in the right and is connected with stator support, taper is supported left side small end and is linked to each other with the base bearing inner ring, the base bearing outer ring links to each other with the mounting flange that is positioned at its right side by bolt II, the circumferencial direction of mounting flange periphery has through hole I, have the through hole II identical on the rotor supports with through hole I radial position, rotor supports and mounting flange link together by the bolt III that places through hole I and through hole II, evenly be furnished with at least two inclined-planes wedge type boss radially at the mounting flange circumferential position, the wedge type boss is provided with at least two screwed hole I, and be provided with wedge, the inclined-plane of wedge matches with wedge type boss inclined-plane, wedge contacts with the internal diameter of rotor supports, on wedge, be provided with at least two through hole III and at least two screwed hole II, bolt IV places screwed hole I by through hole III, bolt V withstands the wedge type boss by screwed hole II, air gap between stator and the rotor is n, guarantee that air gap has the adjustment amount of m, when m≤n, the diameter of through hole II is than the big m of diameter of bolt III, through hole III diameter is than the big m of diameter of bolt IV, like this, under the situation that bolt III and bolt IV do not extract, all can produce relative motion radially between wedge and mounting flange and rotor supports and the mounting flange.
The invention has the beneficial effects as follows: on the wedge type boss wedge is installed, to stator, when rotor assembles, can regulate stator, gap between rotor by regulating the wedge radial position, help guaranteeing that stator, rotor have uniform air gap at circumferencial direction, air gap is regulated simple to operate quick.

Embodiment
The invention will be further described below in conjunction with drawings and Examples.
With reference to accompanying drawing, present embodiment comprises stator 1, stator support 2, rotor 3, rotor supports 4, base bearing outer ring 14, base bearing inner ring 16, taper supports 17, described stator 1 is connected with stator support 2, rotor 3 is connected with rotor supports 4, the big end in 17 the right is supported in taper and stator support 2 is connected, the left side small end of taper support 17 links to each other with base bearing inner ring 16 by bolt I18, base bearing outer ring 14 links to each other with the mounting flange 5 that is positioned at its right side by bolt II 12, the circumferencial direction of mounting flange 5 peripheries has through hole I 6, have the through hole II 7 identical on the rotor supports 4 with through hole I 6 radial positions, rotor supports 4 and mounting flange 5 link together by the bolt III19 that places through hole I 6 and through hole II 7, evenly be furnished with 6 inclined-planes wedge type boss 9 radially at mounting flange 5 circumferential positions, wedge type boss 9 is provided with 2 screwed hole I10, and be provided with wedge 11, the inclined-plane of wedge 11 matches with wedge type boss 9 inclined-planes, wedge 11 contacts with the internal diameter of rotor supports 4, on wedge 11, be provided with 2 through hole III13 and 2 screwed hole II 15, bolt IV20 places screwed hole I10 by through hole III13, bolt V21 withstands wedge type boss 9 by screwed hole II 15, air gap between stator 1 and the rotor 3 is 4mm, guarantee that air gap has the adjustment amount of 4mm, then the diameter of through hole II 7 is than the big 4mm of diameter of bolt III19, through hole III13 diameter is than the big 4mm of diameter of bolt IV20, like this, under the situation that bolt III19 and bolt IV20 do not extract, all can produce relative motion radially between wedge 11 and mounting flange 5 and rotor supports 4 and the mounting flange 5.
Whether even along the air gap of circumferentially checking motor, when the air gap value that detects the somewhere when requiring the air gap value, bolt IV20 near the wedge this detection position 11 is tightened, because wedge 11 sagittal planes tilt, and through hole III13 diameter is bigger than the diameter of bolt IV20, so the outer face of wedge 11 can radially outwards be moved, because of wedge 11 contacts with rotor supports 4, wedge 11 is outside will to be promoted rotor supports 4 when mobile and also outwards move, thereby the feasible rotor 3 that is connected with rotor supports 4 also outwards moves, because the position of stator 1 is constant, so the air gap of this inspection positions will reduce, meanwhile, in the position relative with this detection position, its air gap value is less than requiring the air gap value, bolt IV20 near the wedge this position 11 is unclamped, V21 tights a bolt, this moment, wedge type boss 9 was by jack-up, because wedge 11 sagittal planes tilt, so the outer face of wedge 11 radially moves inward, again because the diameter of through hole I 6 and through hole II 7 is bigger than the diameter of bolt III19, rotor 3 will radially move inward, because stator 1 position is fixed, then the air gap that should locate increases, and other each position is also by at circumferencial direction uniform air gap being arranged up to stator 1 that makes whole motor and rotor 3 with the quadrat method operation.
More than be one embodiment of the present invention, a preferred demonstration example.The scope that patent application of the present invention is asked for protection has more than and is limited to described execution mode.All and technical scheme present embodiment equivalence all belongs to protection scope of the present invention.
