Description

1The invention relates to pole-pole: synchronous electric machines, in particular, to a device for fastening a winding of potential between adjacent poles.

A rotor of a pole-mounted electric machine is known, comprising poles with winding coils, excitations mounted on them using self-aligning strips mounted with their spherical surface on the lateral surfaces of the spacer element, spaced axially split, with a locking element in the section. In this design, the spacer does not provide uniform clamping of the turns of the coil, which can lead to breakage of interpolar. connections, to the violation of monolithic isolation of the turns of the roller due to its vibration. : The purpose of the invention is to increase the reliability of the field winding. To do this, on both ends of the spacer element, protrusions are made restricting the movement of the self-aligning strips along the height | Those whose surfaces, facing the deployment element, are filled with spherical,

 And as the fixing element, a conical stud was used to provide a split number of turns of two adjacent coils.

At the poles 1 of the rotor 2 in the vacant and synchronous machines are located Katui1 of the field of excitation 3, the side contacts of which are wedged with the help of spacers / 4.

Spacer 4 is made detachable; along the axis of the machine, there is a cone hole in the connector, into which the rim is located, the cone pin 5 and the omraN end t are attached to the rod 6, which is located along the rim axis of the rotor 2. 7, allowing wedging of the coils of the field driver, 3.

In the side surfaces of the strut 4, self-restraining clamps are located; j

the strips 8, supported in zappa shiki 9; On the surface 1O, overlapping} {by me, the strips 8, which are in contact with the strut 4, are curvilinear. On the side surface when the press Lank; 8, facing the field winding coils 3, there is an insulating gasket 11 attached to it in a known manner. Coils 3 racks nivakug tightening the nut 7t. The tightening torque of the nut 7 is transmitted through. The stud 6 on the strut 4 and the self-aligning clamping strips 8, which tightly press the turns of the coil 3 along the entire height of the clamp 8, thereby ensuring reliable fastening of the turns of the coils of adjacent poles.

: Self-clamping clamp: Folder 8 is provided by the curvilinearity of the supporting surfaces 10 of the ylanck itself ,. The clamping strips 8 touch the spacer 4 curvature: neyunimn surfaces with both the center of the box storina strina 4 and the ends, Such a spacer provides self-installation of the pressure bars relative to the turns of the coil, allowing evenly
