Abstract

Изобретение позвол ет повысить надежность перемотки ленточных материалов. Устройство содержит размещенные на корпусе ведущий, промежуточный и ведо.мый валы, фрикционный диск, установленный на промежуточном валу и ролик, расположенный на ведомом валу с возможностью осевого перемещении . В торец выходного вала вмонтирован винт-водило, на котором расположены два зубчатых колеса, имеющих разницу в количестве зубьев один или два и наход щихс в зацеплении с удлиненной шестерней, а шестерн -вал предназначена дл предотвращени перекосов. I ил.The invention allows to increase the reliability of rewinding of tape materials. The device contains the leading, intermediate and driven shafts placed on the housing, a friction disk mounted on the intermediate shaft and a roller located on the driven shaft with the possibility of axial movement. At the end of the output shaft, a screw carrier is mounted on which two gears are located, having one or two teeth in difference in the number of teeth that engage with an elongated gear, and the gear-shaft is designed to prevent distortions.

Изобретение относитс к машиностроению , и может быть использовано в механизмах дл сматывани тонких ленточных материалов - отходов штамповочного производства.The invention relates to mechanical engineering, and can be used in mechanisms for coiling thin tape materials - stamping waste.

Цель изобретени - повышение надежности работы.The purpose of the invention is to increase the reliability of work.

На ведуш ем валу 1 закреплены шкив 2 и зубчатое колесо 3, которое находитс в зацеплении с другим зубчатым колесом, закрепленном на валу 4, и на котором расположен фрикционный диск 5 лобового вариатора, контактирующий со след щимA pulley 2 and a gear wheel 3 are engaged on the lead shaft 1, which is engaged with another gear wheel mounted on the shaft 4 and on which the friction disk 5 of the frontal variator is in contact with the follower wheel.

В результате винт-водило 9 вывинчивает от себ зубчатое колесо 8 вместе с роликом 6, тем самым мен ет передаточное число. При достижении роликом 6 крайнего (при полной намотке ленты) положени ступица ролика б вместе с зубчатым колесом 8 резьбой выходит из зацеплени с винтом 9 на безрезьбовую шейку винта 9.

В первоначальное положение ролик 6 устанавливаетс путем несколькихAs a result, the screw carrier 9 unscrews the gear wheel 8 together with the roller 6, thereby changing the gear ratio. When the roller 6 reaches the extreme (when the tape is fully wound), the hub of the roller b, together with the gear wheel 8, disengages from the screw 9 on the threadless neck of the screw 9. By this time the winding of the tape ends, and the output from the engagement of the screw-9 it is provided as blocking from jamming. Roller 6 is set to its original position by several
