Abstract

Изобретение относыс  ручным механизированным инструментам и может бьпь использовано в лесной промышленности Цель изобретени  - более эффективное снижение вибрации руко ток управлени . Переносна  моторна  пила включает опорную рему 1 с руко тками управлени  2 и бензо- бачон 3, пильный аппарат 4, двигатель Ь, коленчатый вал 6, маховик 7 и коническую передачу, состо щую из шестерен 8, 9 с паразитным колесом 10 Вал 11 паразитного колеса 10 расположен перпендикул рно коленчатому валу 6. Опорна  рама 1 соединена с двшателем 5 при помощи амортизаторов 12 Соосно с валом 11 паразитного колеса 10 установлено кольцо 13, состо щее из отдельных секторов Каждый сектор св зан с валом 11 колеса 10 упругими рессорами При работе пилы неуравновешенные силы и моменты привод т к колебани м корпуса двигател  5, которые передаютс  через амортизаторы 12 на руко тки 2 опорной рамы 1 Расположение дополнительной массы кольца 13 на валу паразитного колеса 10 позвол ет увеличить приведенный момент инерции трансмиссии и уменьшить неравномерность вращени  коленчатого вала 6. Это приводит к дополнительному снижению вибрации на корпусе двигател  5 и на руко тках управлени  2. 3 ил.The invention relates to manual mechanized tools and can be used in the forest industry. The purpose of the invention is to more effectively reduce the vibration of the control knobs. The portable motor-saw includes a bearing 1 with control handles 2 and a benzobachon 3, a saw unit 4, an engine b, a crankshaft 6, a flywheel 7 and a bevel gear consisting of gears 8, 9 with a parasitic wheel 10 Shaft 11 of a parasitic wheel 10 is located perpendicular to the crankshaft 6. The supporting frame 1 is connected to the driver 5 by means of shock absorbers 12 Coaxially with the shaft 11 of the parasitic wheel 10 a ring 13 is installed, consisting of separate sectors Each spring is connected to the shaft 11 of the wheel 10 by elastic springs When the saw is unbalanced These forces and moments result in oscillations of the engine casing 5, which are transmitted through shock absorbers 12 to the handles 2 of the support frame 1. The arrangement of the additional mass of the ring 13 on the shaft of the parasitic wheel 10 makes it possible to increase the reduced moment of inertia of the transmission 6. This leads to an additional reduction of vibration on the engine casing 5 and on the control knobs 2. 3 yl.
