Description
Technical field
The series excited machine rotor of a kind of short sleeve technology of the utility model relates to motor production and motor rotor production technology and improves, and belongs to the electromechanical equipment production technical field.
Background technology
Motor is industrialization, modern main symbol, has been widely used in various fields.The kind of motor is more, and different types of motor production technology, specification requirement have nothing in common with each other, and for the combination between high-power synchronous machine manufacturing, especially rotor and rotor winding, is a difficult problem of puzzlement motor manufacturing enterprise always.In traditional production technique, the rotor winding is made, and winding combines the long sleeve pipe insulation technology of most employings with rotor.This mainly is to consider the integrated needs of rotor, but in press-fiting the link of rotor core, because the power of holding tightly between long sleeve pipe and the rotating shaft is bigger; So it is also bigger to press-fit the pressure that needs, press-fiting easy generation deformation in the process at bigger pressure lower rotary shaft, product percent of pass is descended; Even less deformation takes place; Also can have a negative impact to the rotor dynamic balancing, simultaneously, the motor manufacturing cost of using long sleeve technology is than higher.In order further to reduce cost, improve the quality of products and qualification rate, the utility model is open, and a kind of series excited machine rotor of short sleeve technology can be realized reducing manufacture difficulty for this reason, and improve the rotor dynamic equilibrium problems, reduces manufacturing cost simultaneously.
Summary of the invention
The utility model is invented a kind of series excited machine rotor of short sleeve technology.Goal of the invention is: solve the series excited machine rotor in the processing process, reduce production costs, reduce manufacture difficulty, improve the rotor dynamic balancing performance, improve the quality of products and qualification rate.
In order to realize the foregoing invention purpose, the utility model comprises rotating shaft, preceding insulating end plate, rotor core, insulating sleeve pipe, afterwards insulating end plate is formed, and the insulating sleeve pipe box is positioned at mid portion in rotating shaft; Preceding insulating end plate, rotor core, back insulating end plate successively are installed in the rotating shaft of overlapping the pipe spreader of having chance with, and it is characterized in that: rotor core specifically is loaded on the insulating sleeve pipe, and the length of rotor core slightly is shorter than the length of insulating sleeve pipe.
Said rotor insulation pipe spreader length exceeds each 5mm of iron core two ends.
Said front and back insulating end plate integral body is " protruding " font, and its ragged edge edge is equal with the outer of rotor winding.
The rear end of insulating end plate is connected with the front end of insulation insulating sleeve pipe before described, and the front end of preceding insulating end plate extends to the rear end of fan blade.
The rear end of described back insulating end plate is connected with the rear end of insulation insulating sleeve pipe; The rear end of back insulating end plate extends to the front end of commutator.
The rear end of insulating end plate before said, the front end of back insulating end plate all is enclosed within on the insulating sleeve pipe.
Further refinement analysis
The insulating sleeve pipe of said rotating shaft is placed in outer the combining closely with rotor core, winding of rotating shaft and is integrally formed.The existence of insulating sleeve pipe mainly is in order to guarantee the good insulation performance performance to be arranged between rotating shaft and iron core, the winding, also should have integraty preferably simultaneously, so long sleeve technology is all adopted in the insulation of conventional art shaft.But long sleeve technology is used, and processing and manufacturing difficulty in process of production is bigger, and cost is higher, for this reason, changes the short sleeve fabrication techniques at present, and does not change when using long sleeve pipe to make, and the fit system of technological process and each parts shortens use with long sleeve pipe.It is characterized in that: rotor insulation pipe spreader length exceeds about each 5mm of iron core both sides.Reduce holding tightly with joint efforts between sleeve pipe and the axle to reach, reduce the distortion of rotating shaft and reduce manufacturing cost.
The insulating end plate at said iron core and insulating sleeve pipe two ends, for solving between winding enamelled wire and the rotating shaft, insulation and security regulations and set.It is characterized in that: front and back insulating end plate diameter is consistent with rotor winding external diameter, to reach the expose portion that covers the two ends of rotor winding.Preceding insulating end plate length, axle head fan blade place before extending to, back insulating end plate length extends to rear axle end plate commutator place.The similar round mouth funnel of the profile of insulating end plate, the effect of protection, fixing, insulation is played at the two ends of being inserted in the rotor winding.
