Abstract
1. Способ термической обработки лазерным лучом рабочей части зубьев шестерни, отличающийся тем, что поверхностный слой рабочей части зубьев шестерни, изготовленной из ванадиевой стали, нагревают лазерным лучом постоянной плотностью мощности в интервале 107…108 Вт/м2 со скоростью 1…3 см/с, обеспечивают структурные превращения в поверхностном слое, увеличивая твердость от поверхности в глубь, при этом лазерный луч располагают по нормали к рабочей поверхности зубьев, для чего шестерне придают пространственно-колебательное движение. ! 2. Способ по п.1, отличающийся тем, что пространственное движение шестерни осуществляют так, чтобы траектория лазерного луча соответствовала форме рабочей поверхности зуба шестерни. ! 3. Способ по п.1, отличающийся тем, что колебательное движение шестерни осуществляют с частотой 50 Гц с амплитудой колебания до 0,5 мм в направлении, перпендикулярном траектории движения лазерного луча. 1. The method of heat treatment with a laser beam of the working part of the gear teeth, characterized in that the surface layer of the working part of the gear teeth made of vanadium steel is heated by a laser beam with a constant power density in the range of 107 ... 108 W / m2 at a speed of 1 ... 3 cm / s , provide structural transformations in the surface layer, increasing the hardness from the surface to the depths, while the laser beam is placed normal to the working surface of the teeth, for which the gear is given a spatially vibrational motion. ! 2. The method according to claim 1, characterized in that the spatial movement of the gear is carried out so that the path of the laser beam matches the shape of the working surface of the gear tooth. ! 3. The method according to claim 1, characterized in that the oscillatory movement of the gear is carried out with a frequency of 50 Hz with an oscillation amplitude of up to 0.5 mm in a direction perpendicular to the path of the laser beam.
