AI Technical Summary
During the generator winding embedded process, the wire insertion of the stator core with iron ring generator is high and the operation is inconvenient. Especially when the heavy stator core with iron ring generator is embedded, the process of manually rotating the stator core with iron ring generator is cumbersome.
An electric device for wire-embedding of generator windings is designed, including a miniature reducer motor, an active roller, an auxiliary roller and a rubber sleeve. The active roller is driven to rotate through the miniature reducer motor to drive the stator core of the generator with iron ring, and the auxiliary roller assists the rotation through the friction of the rubber sleeve to achieve semi-automatic wire-embedding operation.
The semi-automated operation of generator winding stator core embedded wires is realized, which reduces labor intensity and improves operating efficiency. It is suitable for generator stator core embedded wires with iron ring generators of different specifications, and is safe, maintainable and low-cost.

[0019] As shown in the figure, an electric device for generator winding embedding includes a micro reduction motor 4, and also includes a driving roller 7 and an auxiliary roller 1 horizontally spaced apart on a base 2; the outer walls of the driving roller and the auxiliary roller are provided with a rubber sleeve 8 in contact with the outer wall of the generator stator core; one end of the driving roller is provided with a driven gear 6; the main shaft of the reduction motor is provided with a driving gear 3 meshing with the driven gear, the reduction motor drives the driving roller to rotate through the driving gear and the driven gear, the driving roller drives the stator core of the generator with an iron ring to rotate through the friction force of the rubber sleeve of the driving roller, and the rotating stator core of the generator with an iron ring drives the auxiliary roller to rotate through the friction force of the rubber sleeve of the auxiliary roller.
[0020] The generator stator core is a generator stator core 9 with iron rings. When embedding the wire, the generator stator core with iron rings is placed horizontally between the active roller and the auxiliary roller, and slot paper is inserted into the slots of the stator core. When the winding embedding of each slot at the stator core is completed, the reduction motor drives the stator core to rotate until the next embedding position at the stator core reaches the work station.
[0021] When the next wire embedding position of the stator core reaches the working position, the reduction motor stops, and the active roller and the auxiliary roller stop rotating under the combined action of the gravity of the stator core of the generator with iron rings and the friction of the rubber sleeve.
[0022] The active roller and the auxiliary roller are respectively fixed on the base with KP004 bearing seats 5.
[0023] The rotation speed of the micro reduction motor is not greater than 16r / min.
[0024] A switch for starting and stopping the motor is provided at the power supply circuit of the micro reduction motor.
[0025] Example:
[0026] This example proposes an electric device for generator winding embedding, which converts electrical energy into mechanical energy. The micro reduction motor drives the active roller to rotate, and the generator stator core with iron ring is used as the rotating medium, which indirectly drives the auxiliary roller. Through the friction force of the rubber sleeves on the main and auxiliary rollers, a mechanical transmission is formed in which the active roller, the generator stator core with iron ring and the auxiliary roller are linked together.
[0027] like Figure 1 : Fix the active roller and the auxiliary roller on the base respectively with KP004 bearing seats, and then place the stator core of the generator with iron ring horizontally between the active roller and the auxiliary roller. The micro reduction motor 4 drives the active gear 3, the active gear 3 drives the driven gear 6, and the driven gear 6 drives the active roller 7, and indirectly drives the auxiliary roller 1 through the stator core of the generator with iron ring 9. In this way, the active roller 7, the stator core of the generator with iron ring 9 and the auxiliary roller 1 rotate together through the friction force of the rubber 8.
[0028] When embedding the wire, the stator core of the generator with iron rings is placed horizontally between the active roller and the auxiliary roller, the slot paper is inserted, and the starting device drives the stator core with iron rings to rotate and trim the slot paper. When embedding the wire, the starting device drives the stator core with iron rings to rotate to different positions for embedding the wire for each slot winding.
[0029] In this example, the speed of the micro-reduction motor 4 can be adjusted to 16 r / min. Under the weight of the stator core 9 of the generator with iron rings, the micro-reduction motor 4 is stopped and the device stops rotating.
