METHOD OF DRYING POLYMERIC INSULATION OF FINGERIES OF BRACKETS OF ELECTRIC MACHINE SHIELDS FOR INFRARED LASER RADIATION AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC F26B3/30 

FIELD: machine engineering.

SUBSTANCE: method of drying the polymer insulation of the evenly rotating finger of the bracket of the brush holder EM of electric machines (EM) by infrared (IR) laser radiation is carried out by directing IR laser radiation emitted by an IR laser linearly moving along the axis of rotation of the finger. The device for implementing the drying method consists of a finger holder with a reducer, a container with impregnating material and a lifting mechanism with a fixed IR laser. Cartridge fastening fingers secured to the driven gear reducer driven by an electric motor, and for effecting uniform rotational brush holder bracket fingers around its axis, the container with the impregnating material is placed on the lifting mechanism and is designed for impregnating the brush holder bracket finger dipping, lifting mechanism consists of levers with hinges, rollers and feed screw with electric motor and intended to carry out idling mechanical lifting ma at which the supply container upwardly with the impregnating material, and the stroke of the lifting mechanism in which the feed material down to the impregnating vessel, the IR laser is mounted on an arm lifting mechanism.

EFFECT: energy consumption and time are reduced for process operations by impregnation and drying.
