Abstract
The invention provides a milled groove structure for a high-speed winding motor shaft. The milled groove structure comprises a revolving shaft iron core block, wherein a plurality of grooves are milled in the axial direction of the revolving shaft iron core block; vertical ribs are formed between adjacent grooves; and a key groove is milled in the axial center of one of the vertical ribs. Due to the adoption of the milled groove structure on a shaft of a high-speed winding motor, the shaft diameter is reduced on the premise of ensuring the ventilation area and the critical rotating speed of the motor, the yoke flux density of a rotor is lowered to the maximum extent, and the active power of the motor is increased; and moreover, the shaft is free from a welding seam, so that the safety coefficient is increased under the condition of high rotating speed.
Description
Technical field
The present invention relates to the axle construction of high speed coiling electric motor, the axle that is specifically related to a kind of high speed coiling electric motor mills groove structure.
Background technology
Mostly present high speed coiling electric motor is the flexible shaft rotor; Adopt weldering muscle axle to realize that axle receives size restrictions to do not little and critical whirling speed can not be satisfied the demand, have safety of welding seam property not high on the axle; The little then performance of coiling electric motor slip ring external diameter is excellent in addition, reduces the slip ring external diameter and also need reduce shaft diameter.Therefore from improving motor active power, practice thrift cost, reducing composite factors considerations such as slip ring external diameter and coefficient of safety, adopt the high speed coiling electric motor of weldering muscle axle construction, performance is unsatisfactory.
Summary of the invention
To existing the problems referred to above that adopt the high speed coiling electric motor of weldering muscle axle, the applicant improves through research, provides a kind of high speed coiling electric motor axle to mill groove structure, to improve motor active power, dwindle shaft size, to reduce cost.
Technical scheme of the present invention is following:
A kind of high speed coiling electric motor axle mills groove structure, comprises rotating shaft iron core shelves, said rotating shaft iron core shelves axially be milled with a plurality of grooves, form stud between the adjacent grooves, the axial centre of one of them stud is milled with keyway.
Its further technical scheme is:
Said groove radially evenly distributes rotating shaft iron core shelves, and the degree of depth of said groove is identical, width equates.
The quantity of said groove is even number.
The bottom land of said groove and cell wall transition position are fillet.
Useful technique effect of the present invention is:
The present invention be employed in the high speed coiling electric motor the axle on mill groove structure; Under the prerequisite that guarantees draught area and motor critical speed; Reduce shaft diameter, it is close to reduce rotor yoke magnetic most possibly, improves motor active power; And this structure does not have weld seam on axle, and coefficient of safety increases under high rotating speed.
Description of drawings
Fig. 1 is the radial cross-section after groove is axially milled in the rotating shaft of high speed coiling electric motor.
Embodiment
Further specify below in conjunction with the accompanying drawing specific embodiments of the invention.
As shown in Figure 1, mill machined grooves 2 in the axial of rotating shaft iron core shelves 1 with the disc type milling cutter, groove 2 radially evenly distributes rotating shaft iron core shelves 1, and the degree of depth of each groove 2 is identical, and width equates.The quantity of groove 2 is even number (being 6) in the present embodiment, so that calibration and processing.The gross area of groove guarantees that rotor axial has enough draught areas.Groove depth guarantees that axle remainder equivalent diameter satisfies requirement of strength and support performance.Concentrate to reduce stress with round-corner transition bottom land and cell wall joint.Form stud 3 between the adjacent grooves 2, the equivalent width of stud 3 needs proof strength enough.The axial centre keyseat 4 of a stud 3 (being the stud of the rightmost side in the present embodiment) is used for the rotor bushing iron core therein, realizes the radial location of rotor core.The diameter of rotating shaft iron core shelves 1 equals the internal diameter of rotor punching; After milling groove 2, the equivalent diameter of rotating shaft iron core 1 remainder should be able to proof strength and support performance.
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 basic design of the present invention, all should think to be included within protection scope of the present invention.
