Description
(54) ПЕРЕНОСНАЯ МОТОРНАЯ ПИЛА(54) PORTABLE MOTOR SAW
1one
Изобретение относитс к переносным моторным пилам и может быть использовано в лесной промышленности.The invention relates to portable motor saws and can be used in the forest industry.
По основному авт. св. № 785033 известна переносна моторна пила, включающа корпус двигател , пильный аппарат, бензобак и руко тки управлени , жестко соединенные в опорную раму, имеющую основание полую стойку, амортизаторы, св зывающие стойку с опорной рамой, смонтированный в стойке стержень, верхний конец которого имеет груз, а нижний жестко св зан ° с основанием стойки, подпружиненную относительно основани стойки втулку, св занную тросом с упором, щарнирно смонтированным на корпусе, двигател . В этой мотопиле достигаетс снижение основной гарМОНИКИ опрокидывающего момента двагател на рабочем режиме и холостом ходу 1.According to the main author. St. No. 785033 is a known portable motor saw comprising an engine body, a sawing apparatus, a gas tank and control handles rigidly connected to a support frame, having a base hollow rack, shock absorbers connecting the rack to the support frame, a rod mounted in the rack, the upper end of which has a weight and the bottom is rigidly connected to the base of the rack, spring-loaded relative to the base of the rack, a sleeve connected by a cable with a stop pivotally mounted on the housing of the engine. In this motor saw, the main harmonics of the overturning moment of the two-wheel drive on operating mode and idling 1 are reduced.
Однако дополнительные гармоники указанного момента не подвергаютс гашению, что не позвол ет осуществить высокоэффектное снижение уровн вибрации на двигателе и руко тках мотопилы.However, the additional harmonics of this point are not damped, which does not allow for a highly effective reduction of the vibration level on the motor and chainsaw handles.
Целью изобретени вл етс повышение эффективности гашени вибрации на двигателе и руко тках.The aim of the invention is to increase the efficiency of vibration damping on the engine and the handles.
Цель достигаетс тем, что груз выпол нен в виде стакана, внутри которого вдоль оси установлен упругий стержень, средн часть которого жестко св зана со стенками стакана посредством перемычки, а концы снабжены дополнительными грузами.The goal is achieved by the fact that the load is made in the form of a glass, inside which an elastic rod is installed along the axis, the middle part of which is rigidly connected to the walls of the glass by means of a web, and the ends are supplied with additional weights.
На фиг. 1 изображена переносна моторна пила, общий вид; на фиг. 2 - вид А на фиг. 1.FIG. 1 shows a portable motor-saw, general view; in fig. 2 is a view A of FIG. one.
