(54) ФРИКЦИОННАЯ МУФТА(54) Friction clutch

1one

Изобретение относитс к машиностроению , в частности к устройствам дл передачи врашени .The invention relates to mechanical engineering, in particular to devices for the transfer of dyeing.

Известна муфта, содержаш,а две полумуфты , взаимодействующие от механизма управлени через пружину 1.Known clutch, containing, and two coupling halves, interacting from the control mechanism through the spring 1.

Недостатком его вл етс сложность механизма управлени .Its disadvantage is the complexity of the control mechanism.

Наиболее близка к предлагаемой фрикционна муфта, содержаща ведущую и ведомую полумуфты, выполненные в виде втулок и смонтированный в них упругий элемент.2.Closest to the proposed friction clutch, containing the leading and driven coupling halves, made in the form of bushings and the elastic element mounted in them.

Недостатками его вл ютс разные .стабильности передаваемого момента и малый срок службы.The disadvantages of it are the different stability of the transmitted torque and the short service life.

Цель изобретени - повышение стабильности передаваемого момента и срока службы..The purpose of the invention is to increase the stability of the transmitted moment and service life.

Поставленна цель достигаетс тем., что муфта снабжена компенсационным кольцом , установленном в ведомой полумуфте, а упругий элемент выполнен в виде пружины раст жени с торцами, перпендикул рными оси и установлен в ведущей полу-, муфте с нат гом. Пружина и сопр гаемые с ней поверхности втулок выполнены коническими , кроме того, пружина выполнена из квадратной проволоки переменного сечени .The goal is achieved by the fact that the coupling is equipped with a compensation ring installed in the driven coupling half, and the elastic element is made in the form of an extension spring with the ends perpendicular to the axis and installed in the drive half-, tensioned coupling. The spring and the surfaces of the sleeves mating with it are made conical, in addition, the spring is made of square wire of variable cross section.

На фиг. 1 изображена фрикционна муфта , продольный разрез; на фиг. 2 - коническа пружина; на фиг. 3 - пружины с витками переменного сечени .FIG. 1 shows a friction clutch, a longitudinal section; in fig. 2 - conical spring; in fig. 3 - springs with coils of variable cross section.

Муфта содержит ведущую полумуфту 1 и ведомую полумуфту 2, выполненные в виде втулок с подшипниковыми узлами 3 и 4, установленными на неподвижном валу 5. На ведущей втулке установлено, например, зубчатое колесо 6, при помощи которого она проводитс в непрерывное вращение (привод не показан). Во встречно расположенных отверсти х втулок с нат гом установлена пружина раст жени 7, выполненна либо в виде .винтовой цилиндрической The clutch contains a leading half coupling 1 and a driven half coupling 2, made in the form of sleeves with bearing assemblies 3 and 4 mounted on a fixed shaft 5. On the driving sleeve there is, for example, a gear wheel 6, with which it is held in continuous rotation (drive not shown ). In the oppositely located openings of the sleeves with a tension, a tension spring 7 is installed, either in the form of a screw-type cylindrical

S пружины, либо винтовой конической пружины , или щлифованной пружины из квадратной проволоки. S springs, either a helical conical spring, or a ground wire made of square wire.

Пружина 7 .выставлена относительно стыка контактирующих с.ней поверхностей дл Spring 7. Is set relative to the junction of the contacting surfaces.

Claims

0 is obtained on the south side of the frictional moment and is fixed by a compensation ring 8 mounted on the shaft 5 between the end of the bearing surface of the spring 7 and the bearing unit 3. On the driven sleeve are installed drivers 9 for driving the coil with a tape carrier (not shown). The clutch works in the following way. . When the driving half coupling 1 rotates by a drive, the torque is transmitted to the spring 7 in contact with the driven coupling half 2 connected by a driver 9 with a coil (not shown) having a smaller continuously varying angular velocity. When this spring 7, twisting with friction turns around each other, selects the remaining mounting gap until it stops at the end of the bearing unit 3 through the compensation ring 8, comes into contact along the whole forming line of turns with the surface of the sleeve 2 and slips relative to it. Claims of the invention A friction clutch comprising a driving and driven half coupling, made in the form of bushings and an elastic element mounted in them, characterized in that, in order to increase the stability of the transmitted moment and service life, it is equipped with a compensation ring installed in the driven half coupling and the elastic the element is designed as a spring, stretched with the ends perpendicular to the axis, and is installed in the leading coupling half with tension. 2. The coupling according to claim 1, characterized in that the spring and the surfaces of the sleeves associated with it are tapered. 3. Coupling according to claim 1, characterized in that the spring is made of square wire of variable cross section. Sources of information taken into account during the examination 1.
