Description

Наличие канавок 5 и 6 снижает жесткость элементарного контакта: винт, тело качени , гайка. Из-за сжати  гайки 3 в осевом направлении до плотного прилегани  ее витков одии к другому жесткость винтовой пары определ етс  не жесткостью гайки - пружины, а жесткостью соединени : винт, тело качени , гайка, а также количеством тел качени . Измен   размеры канавок, .выполненных на боковых поверхност х .гайки, и подбира  требуемое количество тел качени , легко получить высокую жесткость предлагаемой винтовой пары.The presence of grooves 5 and 6 reduces the stiffness of the elemental contact: screw, rolling body, nut. Due to the compression of the nut 3 in the axial direction, until its turns fit snugly to another, the stiffness of the screw pair is determined not by the stiffness of the nut - spring, but by the stiffness of the connection: screw, rolling body, nut, and the number of rolling bodies. By changing the dimensions of the grooves made on the side surfaces of the nut, and selecting the required number of rolling elements, it is easy to obtain a high rigidity of the screw pair.
