Вращение эксцентриков преобразуетс  в поперечные перемещени  cncTeLMbi черв чна  пара - коническа  пара шестерен, а вместе с ней .и в поперечные .перемещени  бурового става 4. Это (вызывает /сложную траекторию движени  коронки 5 по забою, ш результате чего поперечное сечение шпура увеличиваетс , а сама коронка контактирует со стенками щлура только в одной точке, не вызыва  ,их заглажива и , что .повышает дегазирующее воз(действие шпура на массив.axially in the hole of the gear 14, it rotates, which is then transmitted through gear 13, the worm to 12 and the worm gear 11 to the eccentrics 10. The rotation of the eccentrics is converted into lateral movements together with it. and in transverse movements of the drill rod 4. This (causes / complex trajectory of the crown 5 on the face, w resulting in the cross-section of the hole increases, and the crown itself contacts the walls of the hole only at one point a and that increases the degassing power (the effect of the hole on the array.
