Abstract

Изобретение относится к машиностроению, в частности к приводным механизмам, и может быть использовано в робототехнике и в станочных приводах. Заявленный двухступенчатый планетарно-цевочный редуктор включает установленный на жестко связанных между собой двух неподвижных фланцах поворотный корпус, на внутренней поверхности которого установлены оси, находящиеся в зацеплении с эпициклоидальными зубьями сателлитов, причем каждый сателлит установлен на трех ведомых валах, равномерно размещенных по окружности и закрепленных во фланцах с возможностью вращения, при этом ведомые валы посредством зубчатой передачи кинематически связаны с центрально расположенным входным валом, три одинаковых сателлита установлены на ведомых валах через эксцентриковые подшипники с поворотом каждого сателлита на угол 120°, при этом количество осей поворотного корпуса, количество зубьев зубчатых колес ведомых валов и шестерен входного вала кратно трем. В частном случае выполнения зубчатая передача между ведомыми валами и входным валом может быть выполнена двухрядной, на шлицах ведомого вала последовательно установлены первое зубчатое колесо, три эксцентриковых подшипника с сателлитами и второе зубчатое колесо, а количество шлицев на ведомых валах кратно трем. Кроме того, одинаковые шестерни входного вала могут быть установлены на шлицах, зубья шестерен входного вала нарезаны со смещением относительно шлицев на величину, равную 1/2 зазора в зубчатом зацеплении, а шестерни установлены оппозитно. Также два неподвижных фланца могут быть соединены между собой при помощи ступенчатых пальцев, центральная ступень которых выполнена утолщенной.The invention relates to mechanical engineering, in particular to drive mechanisms, and can be used in robotics and machine tool drives. The claimed two-stage planetary-gear reducer includes a rotary body mounted on rigidly interconnected two fixed flanges, on the inner surface of which axles are mounted that engage with the epicycloidal teeth of the satellites, each satellite being mounted on three driven shafts uniformly placed around the circumference and fixed in flanges with the possibility of rotation, while the driven shafts by means of a gear are kinematically connected with a centrally located input shaft, t and the same satellite are mounted on the driven eccentric shafts through bearings with the rotation angle of each satellite at 120 °, while the number of rotary axes of the housing, the number of gear teeth driven shafts and gears of the input shaft of a multiple of three. In the particular case of a gear transmission between the driven shafts and the input shaft can be made two-row, the first gear wheel, three eccentric bearings with satellites and the second gear wheel are sequentially installed on the splines of the driven shaft, and the number of splines on the driven shafts is threefold. In addition, the same gear input shaft can be installed on the splines, the teeth of the gears of the input shaft are cut offset from the splines by an amount equal to 1/2 of the gap in the gear teeth, and the gears are installed opposite. Also, two fixed flanges can be interconnected by means of stepped fingers, the central step of which is made thickened.
