Abstract
Изобретение относитс к машиностроению и м. б. использовано в качестве привода исполнительных механизмов с прерывистым движением при больших нагрузках Цель - повышение надежности работы и долговечности механизма путем устранени трени собачки и фиксатора о зубь храпового колеса при холостом ходе. Храповой механизм включает храповое колесо 1, установленное на ведомом валу 2, расположенном на стойке 3, и приводную собачку. Последн выполнена в виде двуплечего рычага 4 и закрепленного на одном его конце подпружиненного наконечника 5. Другой конец двуплечего рычага 4 посредством т ги 9 с пальцем 11 св зан с коромыслом 13 и приводом (П) 8 в виде силового цилиндра. При перемещении П 8 палец 11, пройд весь паз 12, вступает в контакт с коромыслом 13 и поворачивает его против часовой стрелки, вывод из зацеплени с зубь ми храпового колеса 1 фиксатор 16 В начале рабочего хода П 8 палец 11 перемещает вдоль паза 12 коромысло 13, которое продолжает оставатьс в покое, удерживаемое силой трени от пружины При этом наконечник 5 входит в зацепление с храповым колесом 1 и при дальнейшем перемещении П 8 поворачивает храповое колесо 1 относительно вала 2. 6 ил Ј (/This invention relates to mechanical engineering and m. B. used as a drive for actuators with intermittent movement under heavy loads. The goal is to increase the reliability of operation and durability of the mechanism by eliminating the friction of the dog and the lock on the teeth of the ratchet wheel when idling. The ratchet mechanism includes a ratchet wheel 1 mounted on the driven shaft 2, located on the rack 3, and the drive dog. The latter is made in the form of a two-arm lever 4 and a spring-loaded tip 5 fixed at one end thereof. The other end of the two-arm lever 4 is connected to the rocker 13 and the drive (P) 8 in the form of a power cylinder by means of a pull 9 with a finger 11. When P 8 is moved, the finger 11, having passed the entire groove 12, comes into contact with the rocker 13 and turns it counterclockwise, disengages the ratchet wheel 1 with the teeth of the latch 16 At the beginning of the working stroke P 8, the finger 11 moves along the groove 12 the rocker 13 which continues to remain at rest, held by the force of friction from the spring. In this case, the tip 5 engages with the ratchet wheel 1 and with further movement of P 8 turns the ratchet wheel 1 relative to shaft 2. 6 il Ј (/
