(З) УПРУГАЯ МУФТА(H) ELASTIC CLUTCH

1one

Изобретение относитс к машиностроению .The invention relates to mechanical engineering.

Известны упругие муфты, содержащие две полумуфты, соединенные торообразной оболочкой til.Known elastic couplings containing two half-couplings connected by a toroidal shell til.

Недостатками этой муфты вл ютс высока линейность характеристики и сложность изготовлени оболочки.The disadvantages of this coupling are the high linearity of the characteristics and the complexity of manufacturing the casing.

Наиболее близкой к предлагаемой вл етс упруга муфта, содержаща две Нолумуфты, соединенные упругими элементами С-образного сечени 2.Closest to the present invention is an elastic coupling comprising two zero couplings connected by elastic elements of a C-shaped section 2.

Недостатками этой муфты вл ютс отсутствие предохранительных свойств и линейность упругой характеристики.The disadvantages of this coupling are the lack of safety properties and the linearity of the elastic characteristic.

Цель изобретени - расширение эксплуатационных возможностей муфты за счет п эидани ей предохранительных свойств и изменени упругой характеристики .The purpose of the invention is to expand the operational capabilities of the coupling due to the protection properties and changes in the elastic characteristic.

Поставленна цель достигаетс тем, что упруга муфта, содержаща две полумуфты, соединенные упругими элементами С-образного сечени , снабжена соединительными пальцами, одна из полумуфт выполнена в виде двух, соединенных между собой дисков с кулачками на периферийной поверхности, друга - в виде барабана с радиальными прорез ми в боковых стенках, расположенного между дисками, упругие элементы шарнирно соединены с пальцами, расположенными параллельно оси муфты равномерно по окружности в два р да, при этом концы пальцев внутреннего р да закреплены в дисках , а концы пальцев внешнего р да установлены в пазах барабана с возможностью перемещени и взаимодействи с кулачками дисков.The goal is achieved by the fact that the elastic coupling, containing two coupling halves connected by elastic C-section elements, is provided with connecting fingers, one of the coupling halves is made in the form of two disks connected to each other with cams on a peripheral surface, and the other in the form of a drum with radial slots in the side walls located between the disks, the elastic elements are pivotally connected to the fingers parallel to the axis of the coupling evenly circumferentially in two rows, with the ends of the fingers of the inner p Yes, they are fixed in the disks, and the ends of the fingers of the outer row are installed in the grooves of the drum with the possibility of movement and interaction with the cams of the disks.

Claims

The clutch contains elastic C-section elements 1, the sides of which are vulcanised bushes 2 and 3, pivotally connected to fingers C and 5, axially fixed washers 6 and 7 and resting on two discs with cams 8 and 9. Bar 10 s radial grooves in the side walls are connected to half coupling 11 Cams 8 and 9 are fixed on sleeve 12 The coupling works as follows. The torque from the coupling half 11 through the drum 10, the fingers 5g the disks with the cams 8 and 9 and the elastic elements 1 is transferred to the sleeve 12. as torque increases the rotation of elastic elements in the hinges, their elongation and along the gate of the coupling half relative to each other. At the same time, the ends of the fingers move along the profile of the cams 9. This causes their movement in the radial grooves of the drum 10, the additional elongation of the elastic elements and the increase in the stiffness of the coupling. When the moment reaches the maximum value, the fingers 5 move out in the radial direction to the maximum value and begin to slip relative to the cams 8 and 9, disconnecting the kinematic chain. The cam profile can be changed. The law of change in torsional rigidity and the magnitude of the maximum torque transmitted by the clutch. The use of the coupling allows to obtain a series of nonlinear elastic characteristics without replacing the elastic elements by changing the shape of the cam profile and protects the drive parts from overloads when the moment reaches a value greater than the specified one, which expands the range of its use and improves the smoothness of the drive, its reliability and durability. The invention of the Elastic Coupling, containing two half-couplings connected by elastic elements of the C-shaped section, is necessary to enhance the operational capabilities by imparting safety properties and the possibility of changing the elastic characteristic. connecting fingers, one of the coupling halves is made in the form of two disks interconnected with cams on the peripheral surface, and the other in the form of a drum with radial slits in the side walls located between the disks, the pack These elements are pivotally connected with said fingers parallel to the axis of the coupling evenly circumferentially in two rows, with the ends of the fingers of the inner row fixed in the disks, and the ends of the fingers of the outer row are mounted in the grooves of the drum with the ability to move and interact with cams of disks.
