Embodiment Construction
[0017] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0018] Such as figure 1 As shown, the damping wheel 2 is fixed on the support frame 1, the enameled wire 4 is pulled out from the cylindrical coil 3 mounted on the damping wheel 2, and the enameled wire 4 passes through the guide wheel 5, the tensioning wheel 24, and the limit wheel 11 one by one. After winding on the salient pole rotor 12. The salient pole rotor 12 is mounted on the rotary table 14 , the motor 20 is connected to the reducer 17 through a coupling 21 , and the output shaft of the reducer 17 is connected to the rotary table 14 through a connecting flange 16 .
[0019] The motor 20 rotates to drive the shaft coupling 21 and the reducer 17, and after being decelerated by the reducer 17, it is output by the output sha...

The invention discloses a salient pole rotor coil winding device for realizing the adjustable tension and the maintenance of the constant tension of an enameled wire. The device comprises a closed-loop negative feedback constant tension automatic control mechanism. When the tension of the enameled wire is changed, a tension wheel moves up and down, and a movable block is driven to move up and down. A pressure sensor installed between the movable block and the spring senses the change of pressure. According to the mechanism, the closed-loop negative feedback constant tension automatic control is formed, and the tension of the enameled wire is constant. The tension can be set in advance, when large tension is needed, the position of an adjusting screw is adjusted to be lower, the spring prepressure is increased correspondingly, and the movable block is pushed to press downward such that the tensioning force of the enameled wire is increased correspondingly. The enameled wire which is connected between a guide wheel and a limiting wheel is pressed by a tensioning wheel, and the included angle between the guide wheel and the tensioning wheel is same with the included angle between the enameled wire between the guide wheel and the limiting wheel and the tensioning wheel center vertical line. According to the salient pole rotor coil winding device, the electric performance of the enameled wire is stable and reliable, and a guarantee is provided for the production of generators with excellent and reliable performance.
Description
technical field [0001] The present invention relates to mechanical equipment, in particular, the present invention relates to a salient pole rotor coil winding device. Background technique [0002] At present, the salient pole rotor coils used in domestic generators are mainly wound by hand, and the salient pole rotor automatic winding machines are only produced in the United Kingdom and the United States, but the price is very expensive. Manual winding has problems such as high cost and low efficiency, non-adjustable and unstable enameled wire tension. Contents of the invention [0003] The purpose of the present invention is to provide a salient pole rotor coil winding device which realizes the adjustable tension of the enameled wire and keeps the tension constant through the closed-loop control of the controller after adjustment. [0004] The technical solution provided by the present invention is: a salient pole rotor coil winding device, including a support frame 1, ...
