(54) РЕВЕРСИВНЫЙ ЛЕНТОПРОТЯЖНЫЙ МЕХАНИЗМ(54) REVERSIBLE TAPE MECHANISM

1one

Изобретение относитс к области накоплени информации,а именно к ре- версивным лентопрот жным механизмам.The invention relates to the field of accumulation of information, namely, to reverse tape-carrying mechanisms.

Известен.реверсивный лентопрот жный механизм, содержащий электродвигатель , кинематически соединенный с реверсивным ведущим узлом, смонтиро-. ванным с возможностью воздействи на магнитную ленту 1 .The known reversible tape mechanism, containing an electric motor, kinematically connected to a reversible driving unit, is mounted. with the possibility of affecting the magnetic tape 1.

Такой реверсивный лентопрот жный механизм имеет относительно простую конструкцию, однако потребл ет значительную энергию на прот гивание магнитной ленты.Such a reversible tape mechanism has a relatively simple design, but consumes considerable energy to pull the magnetic tape.

Известен также реверсивный лентопрот жный механизм, содержащий реверсивный электродвигатель, кинематически соединенный с пассиками, размещенными на обгонных муфтах разностороннего действи , укрепленных соосно с ведущими валами, установленными в бесконечных ремн х, сопр женных с рулонами магнитной ленты, размещенными на сердечниках, и расположенных на обводных роликах, укрепленных на поворотных рычагах, установленных на корпусе 2.Also known is a reversible tape mechanism, which contains a reversible electric motor, kinematically connected to crawlers placed on overrunning clutches of a versatile action, fixed coaxially with drive shafts mounted in endless belts coupled to rolls of magnetic tape placed on cores and located on crawlers rollers, mounted on the swivel arms mounted on the housing 2.

Известный реверсивный лентопрот жный механизм потребл ет относительно небольшое количество энергии на транспортирование магнитной ленты.The known reversing tape mechanism consumes a relatively small amount of energy to transport the magnetic tape.

Недостаток подобного реверсивного лентопрот жного механизма состоит в значительном вли нии ударов и вибраций на него.The disadvantage of such a reversible tape mechanism is the significant impact of shocks and vibrations on it.

Цель изобретени - уменьшение вли ни ударов и вибраций на реверсивный лентопрот жный механизм.The purpose of the invention is to reduce the impact of shocks and vibrations on the reversing tape mechanism.

Цель достигаетс за счет того, что в реверсивный лентопрот жный механизм введены дополнительные оОводные ролцки, неподвижно укрепленные на корпусе и сопр женные с бес-г The goal is achieved due to the fact that additional water rollers are fixed in the reversing tape mechanism, fixed to the body and connected

15 конечными ПЛОСКИМИ ремн ми, а поворотные рычаги подпружинены один к другому.15 end FLAT belts, and pivoting levers are spring-loaded to one another.

На чертеже показан один из возможных вариантов предложенного ре20 версивного лентопрот жного механизма.The drawing shows one of the possible variants of the proposed reproducing tape mechanism.

Claims

The mechanism contains a reversible electric motor 1, kinematically connected by means of pulleys 2 and 3 to passives 4 and 5. Passik 4 is placed on overrunning clutches 6 of versatile action, and pass 5 is on overrunning clutches 7 of versatile action with which it is coupled through friction ring elements 8. 30 Overrunning clutches b and 7 of versatile operation are fortified coaxially with driving shafts 9 installed in endless flat belts x 10 and located on the bypass rollers 11 mounted on the swivel levers 12 mounted on the housing 13 and spring-loaded one to the other by means of a spring 14. Endless flat straps 10 are also matched with ilS rolls of magnetic tape 1b | placed on the cores 17. In this case, the magnetic tape 16 is coupled with the guide rollers 18 and magnetic heads 19. The proposed tape drive mechanism also contains additional bypass rollers 20, coupled with endless flat belts 10. Moreover, additional bypass rollers the rollers 20 are fixedly mounted on the housing 13. The ribbing of the magnetic tape 16 is ensured by rotating the respective drive shaft 9, moving the endless flat belt 10 placed on it. Moving an endless flat p Mn 10 causes the rotation of the coil 15 of the magnetic tape 15 matched to it. Due to this, the latter is pulled out from the other coil 15 of the magnetic tape 16, braked by another endless flat belt 10. Using the invention significantly reduces the effect of shocks and vibrations on the reversible leprosy mechanism. Claims of the invention A reversible tape mechanism comprising a reversible electric motor, kinematically connected to crawlers, placed on overrunning clutches of versatile action, fortified coaxially with leading All-in-line belts, coupled with rolls of magnetic tape, placed: on cores, and located on bypass rollers mounted on pivot arms mounted on the housing, characterized in that, in order to reduce the impact of shocks and vibrations, additional tional deflection rollers fixedly on the housing and fortified conjugated with endless flat belts, and the pivot arms are biased toward one another.
