Abstract

Изобретение относитс к выемочным машинам и может быть использовано в горной или горнодобывающей промышленности. Цель - повышение надежности работы машины за счет исключени реверса привода при смене направлени движени машины. Она включает корпус 1, поворотные редукторы 2 с исполнительными органами /ИО/ 3, бесцепной механизм подачи с колесами 11 и его привод 19. Последний выполнен в виде т говой цепи /ТЦ/ обводной звездочки и приводных звездочек 5, кинематически св занных между собой и установленных на центральных валах 4, имеющих зубчатые колеса 12 и 13. При этом ТЦ 18 установлена с возможностью взаимодействи со звездочкой и обхвата обеих звездочек 5 с противоположных сторон. Кажда звездочка 5 св зана с соответствующим колесом 11 поседством электромагнитной муфты 14. При включении привода 19 через ТЦ 18 и звездочки 5 передаетс вращение на ИО 3, т.е. до начала движени машины ИО 3 начинают работу. Движение машины произойдет после включени муфты 14. При работе ИО 3 при реверсе направлени перемещени не мен ют направление вращени . 2 ил.The invention relates to excavation machines and can be used in the mining or mining industry. The goal is to increase the reliability of the machine by eliminating the reverse of the drive when changing the direction of the machine. It includes body 1, swivel gearboxes 2 with executive bodies / IO / 3, chainless feed mechanism with wheels 11 and its drive 19. The latter is made in the form of a traction chain / TC / bypass sprocket and drive sprockets 5, kinematically connected with each other and mounted on central shafts 4 having gears 12 and 13. At the same time, the shopping center 18 is installed with the ability to interact with the asterisk and the girth of both asterisks 5 from opposite sides. Each sprocket 5 is associated with a corresponding wheel 11 by the electromagnetic clutch 14. When the actuator 19 is turned on, the TC 18 and the sprocket 5 are transmitted to IO 3, i.e. Before the start of the movement, the IO 3 machines begin to work. The movement of the machine will occur after the clutch 14 is turned on. When the IO 3 operates with the direction of movement reversed, the direction of rotation does not change. 2 Il.
