Abstract

Изобретение относитс  к машиностроению, а именно к опорно-поворотным устройствам башен со след щим приводом, например башен стационарного телескопа. Цель изобретени  - повышение долговечности путем снижени  нагрузочного момента. Крестово-роликовый подшипник состоит из внутреннего 2 и наружного 1 колец, цилиндрических роликов 3 высотой, меньшей, чем диаметр, и сепарирующих антифрикционных вкладышей 6, охватывающих ролики по части их цилиндрической и торцовых поверхностей. При вращении колец и роликов сепарирующие антифрикционные вкладыши 6 преп тствуют касанию торцов роликов 3 о дорожки качени  4 и 5. Трение роликов 3 о вкладыши остаетс  величиной посто нной, т.к. во всех случа х контактирование происходит одними и теми же элементами, что позвол ет снизить нагрузочный момент и повысить плавность вращени . 3 ил.The invention relates to mechanical engineering, in particular to rotary support devices of towers with a tracking drive, for example, towers of a stationary telescope. The purpose of the invention is to increase durability by reducing the load torque. The cross-roller bearing consists of inner 2 and outer 1 rings, cylindrical rollers 3 with a height less than the diameter, and separating antifriction liners 6, covering the rollers on a part of their cylindrical and end surfaces. During the rotation of the rings and rollers, the separating antifriction liners 6 prevent the ends of the rollers 3 from touching the raceway 4 and 5. The friction of the rollers 3 against the bearings remains constant as In all cases, the contacting occurs with the same elements, which makes it possible to reduce the loading moment and to increase the smoothness of rotation. 3 il.
