Abstract
The invention discloses a hot sleeve structure of a large electromotor rotor core, comprising a revolving shaft which is sheathed with the rotor core, the two ends of the rotor core are mounted with two clamping seat boards, annular grooves are opened outside the two clamping seat boards in the circumstance of the revolving shaft, supporting seat boards are embedded in the annular grooves, and a jacking device is arranged between the supporting seat boards and the clamping seat boards. The invention adopts the manners of opening grooves on the revolving shaft, arranging supporting seat boardsin the grooves and pressing the rotor core by the jacking device through the clamping seat boards, thus effectively avoiding the phenomenon of shaft climbing of the rotor core, ensuring the service life of the electromotor to be greatly enhanced, and producing almost no influence on mechanical property of the electromotor shaft.
Description
Technical field
The present invention relates to motor, be specifically related to the shrunk-in shaft structure of high capacity motor rotor core.
Background technology
Existing high capacity motor is in order to strengthen the rigidity of high-speed electric expreess locomotive rotating shaft, and solution critical whirling speed problem, mostly adopt rotor punching to build up back unshakable in one's determination shrunk-in shaft technology, the axle surface keyseat not that this technology is cooperating with iron core, motor transmitted power or moment of torsion be without key, but rely on the interference fit of circle and axle in the rotor core fully.Large-size machine is too big because of its shaft length size, and when adopting shrunk-in shaft technology, rotor core is heated to fitting temperature, puts a back natural cooling.When using shrunk-in shaft technology, as not adding certain treatment measures, " climbing axle " phenomenon of rotor core appears in rotor core through regular meeting in cooling procedure, i.e. rotor core departs from axial length in cooling procedure, make motor reduce greatly useful life.
The content of invention
Above-mentioned deficiency at existing high capacity motor rotor core shrunk-in shaft structure, the applicant improves through research, the shrunk-in shaft structure of another kind of high capacity motor rotor core is provided, be implemented under the situation that does not change structural material, guaranteeing under the motor shaft characteristic acceptance condition, take the measure of advantages of simple, solve in the problem that does not have high-quality enforcement Large Rotor shrunk-in shaft technology unshakable in one's determination under the situation of large-scale press device.
Technical scheme of the present invention is as follows:
A kind of shrunk-in shaft structure of high capacity motor rotor core, comprise rotating shaft, be set with rotor core in the rotating shaft, the two ends of rotor core are equipped with the clamping seat board, clamp the outside of seat board in the groove that circumferentially has ring-type of rotating shaft two, groove is embedded with the support seat board, between support seat board and clamping seat board jack unit is installed.
Its further technical scheme is: be connected with at least three jack units of evenly arranging between described support seat board and relative clamping seat board thereof.
Its further technical scheme is: the width of described groove is 40mm, and the degree of depth is 20mm.
Its further technical scheme is: described jack unit is a jack device.
Useful technique effect of the present invention is:
The present invention's employing recessing in rotating shaft also is provided with the support seat board therein, with jack unit by clamping the mode that seat board is exerted pressure to rotor core, effectively avoided the appearance of the rotor core phenomenon of " climbing axle ", motor is improved useful life greatly, and the mechanical property of motor rotary shaft is not almost influenced.
Description of drawings
Fig. 1 is a structure chart of the present invention.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further.
As shown in Figure 1, the present invention includes rotating shaft 1, be set with rotor core 2 in the rotating shaft 1, the two ends of rotor core 2 are equipped with two and clamp seat board 5, two clamping seat boards 5 with rotor core 2 clampings.Clamp the outside of seat board 5 in the groove that circumferentially offers ring-type 6 of rotating shaft 1 two, the width of described groove 6 is 40mm, the degree of depth is 20mm, groove 6 is embedded with and supports seat board 4, be connected with the jack unit of evenly arranging more than three 3 between the sidewall that supports seat board 4 and the clamping seat board 5 relative with it, described jack unit 3 is a jack device.Jack unit 3 of the present invention exerts pressure for rotor core 2 by clamping seat board 5, and rotor core 2 axially be not offset in cooling procedure, has effectively avoided " climbing axle " phenomenon of rotor core 2.
Installation process of the present invention is as follows: after treating that rotor core 2 hot jackets are installed in the rotating shaft 1, the semicircular ring chuck that place two specialized designs, processes, two semicircular ring chucks are closed as a whole with bolt as supporting seat board 4, between the sidewall that supports seat board 4 and clamping seat board 5, the jack unit of evenly arranging more than three 3 is installed, exert pressure for rotor core 2 by clamping seat board 5, finish hot cover process.After hot cover process is finished, treat rotor core 2 coolings to a certain degree, then can pull down supporting seat board 4.
Above-described only is preferred implementation of the present invention, the invention is not restricted to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from spirit of the present invention and design, all should think to be included within protection scope of the present invention.
