Abstract
Изобретение относитс к лесной промышленности и может использоватьс в машинах дл валки и раскр жевки леса. Целью вл етс повышение надежности и упрощение конструкции. Пильное устройство содержит корпус 1, гидродвигатель 2, поворотный кронштейн 3 с шиной 4, звездочку 5, пильную цепь 7. Звездочка 5 установлена со стороны шины 4 в кронштейне через подшипник 6 и подсоединена к валу двигател 2, а с противоположной подшипнику стороны поджата упором 9 относительно корпуса. Упор 9 обеспечивает фиксирование звездочки 5 и кронштейна 3 в корпусе от осевого перемещени . Установка звездочки 5 в кронштейне 3 обеспечивает надежное совмещение направл ющих дл цепи 7 на шине 4 и звездочке 5. Работа пильного устройства осуществл етс включением двигател 2 и привода поворота кронштейна 3, злтсм ора- щением звездочки 5 приводитс о действие пильна цепь 7 и осуществл етс надвигание на срезаемое дерево. После завершени пилени привод поворота кронштейна 3 реверсируют, шина 4 и кронштейн 3 возвращаютс в исходное положение. 1 з. п. ф-лы, 3 ил. (Л СThe invention relates to the forest industry and can be used in machines for felling and cutting wood. The goal is to increase reliability and simplify the design. The sawing device includes a housing 1, a hydraulic motor 2, a swing arm 3 with a tire 4, an sprocket 5, a saw chain 7. The sprocket 5 is installed on the tire 4 side in the bracket through the bearing 6 and connected to the engine shaft 2, and an emphasis 9 relative to the body. The stop 9 provides for fixing the sprocket 5 and the bracket 3 in the housing against axial movement. The installation of the sprocket 5 in the bracket 3 ensures reliable alignment of the guides for the chain 7 on the tire 4 and the sprocket 5. The saw device is operated by turning on the engine 2 and the rotation drive of the bracket 3; Sliding on the tree being cut. After the sawing is completed, the rotation drive drive of the bracket 3 is reversed, the tire 4 and the bracket 3 return to their original position. 1 h. n. f-ly, 3 ill. (Ls
