Description

большие по величине, нежели остаточные напр жени , созданные в секторе с меньшим усилием накатывани . Поэтому геометрическа  форма вала будет измен тьс , приближа сь к ир молинейной, до тех нор, пока внутренние напр жени  не уравновес тс .larger than residual stresses created in the sector with less rolling force. Therefore, the geometrical shape of the shaft will change, approaching the ir linear, until the internal stresses are balanced.

Можно подобрать такую программу изменени  усили  обработки галтели вала по окружности , чтобы биение последнего вошло в допустимые границы.It is possible to choose such a program for changing the processing forces of the fillet shaft around the circumference, so that the beating of the shaft is within the permissible limits.

Частным случаем описанного выше способа  вл етс  секториальна  (частична ) обработка галтели поверхностно-пластическим деформированием , когда обрабатывают только сектор галтели, расположенный со стороны вогнутости вала. Например, дл  достижени  правильной геометрической формы вала (фиг. 1) достаточно обработать с определенными усили ми сектор галтели 135 -180°- 225°.A special case of the method described above is sectorial (partial) treatment of fillets by surface plastic deformation, when only the fillet sector located on the side of the shaft concavity is processed. For example, in order to achieve the correct geometrical shape of the shaft (Fig. 1), it is sufficient to process the sector of the fillet 135-180 ° - 225 ° with certain forces.

Claims (2)

1. Способ упрочнени  галтелей валов поверхностным пластическим деформированием, отличаюшийс  гем, что, с целью повышени  усталостной прочности вала и обеспечени  правильной геометрической формы, поверхностное пластическое деформирование производ т переменным усилием, прилага  максимальное усилие со стороны вогнутости вала и минимальное со стороны выпуклости вала.1. The method of hardening shaft shafts by surface plastic deformation, characterized by heme, which, in order to increase the fatigue strength of the shaft and ensure the correct geometric shape, surface plastic deformation is effected with a variable force, exerting maximum force from the shaft concavity and minimum from the shaft bulge. 2. Способ по п. 1, отличающийс  тем, что поверхностное пластическое деформирование производ т посто нным усилием, причем усилие прикладывают только на участке вогнутости вала.2. A method according to claim 1, characterized in that the surface plastic deformation is carried out with a constant force, the force being applied only in the concavity of the shaft. 777777777777 Риг.1Riga.1
