Abstract

Изобретение относитс к машиностроению . Цель изобретени - повышение надежности устройства. В корпусе 1 наход тс ведущий 2 и ведомый 3 диски. Внутренние поверхности дисков 2 и 3 в сечении имеют полусферические поверхности , на которых расположены углублени . Углублени расположены на концентрических окружност х - уровн х с равным шагом как между углублени ми на самом уровне. так и между уровн ми, причем между уровн ми углублени соедин ютс канавкой попарно Между ведущим 2 и ведомым 3 дисками расположена опора 8, на которой укреплен подшипник 7 качени Подшипник 7 качени имеет внутреннюю обойму, закрепленную шарнирно на опоре 8, а наружна представл ет собой сочленение двух колец наружного, имеющего радиальные сквозные отверсти , в которые вставлены шарики 12, и среднего на наружном торце которого имеютс радиальные углублени . Шаг между шариками 12 и углублени ми в любом уровне на дисках 2 и 3 одинаков. Управление подшипником 7 осуществл етс через руко тку 17, внутри которой имеетс кнопка, св занна с двуплечим рычагом 19 через т гу 18. На концах двуплечего рычага 19 укреплены фрикционные колодки 20 так, что при нажатии на кнопку они соприкасаютс со средним кольцом подшипника 7. 5 ил. сл сThe invention relates to mechanical engineering. The purpose of the invention is to increase the reliability of the device. In case 1 there are master 2 and slave 3 disks. The inner surfaces of the disks 2 and 3 in cross section have hemispherical surfaces on which recesses are located. The recesses are located at concentric circles — levels with equal pitch as between the recesses at the level itself. and between levels, and between the levels of the recess are connected in pairs by a groove Between the driver 2 and the slave 3 disks there is a support 8, on which the rolling bearing 7 is strengthened. The rolling bearing 7 has an inner holder fixed pivotally on the support 8, and the articulation of two outer rings, having radial through holes, into which balls 12 are inserted, and on the middle end of which there are radial recesses. The pitch between the balls 12 and the recesses in any level on the disks 2 and 3 is the same. The bearing 7 is controlled through the handle 17, inside of which there is a button connected to the double-arm lever 19 through bar 18. At the ends of the double-arm lever 19, the friction pads 20 are fastened so that when the button is pressed, they touch the middle ring of the bearing 7. 5 il. cl

Claims

Claim

A multi-interval step gear comprising a housing in which the driving and driven disks are located, a bearing, a rolling bearing connected to the bearing, and a gear shifting mechanism, characterized in that, in order to increase reliability, the driving and driven disks are made with internal spherical surfaces on which spherical grooves located on concentric circles-levels with equal steps both between themselves and between circles-levels, grooves on adjacent levels are connected in pairs by grooves, n The outer race of the rolling bearing is made up of the outer and middle rings that are mounted for relative rotation and fixing, in the outer ring there are made radial through holes with a step equal to the pitch of the recesses on the disks, the middle ring is made with radial recesses equal to the number of holes in the outer ring, the gear is equipped with balls installed in the radial through holes of the outer ring of the bearing, 5 the inner race of the bearing is pivotally mounted on the support, and the gear mechanism with bones is connected with the middle ring of the bearing.
