Description

щей полумуфты 3 относительно ведомой по центрирующей втулке 9, см гча толчки и удары в передаче.coupling half 3 relative to the driven centering sleeve 9, see gcha pushes and shocks in the transmission.

При достижении максимального момента кулачки обеих полумуфт вход т во взаимный контакт, предохран торсион от перенапр жени и поломки.When the maximum moment is reached, the cams of both coupling halves enter into mutual contact, protecting the torsion from overvoltage and breakage.

Упругое закручивание торсиона 5 создает также трение между пластинами 6, что способствует затуханию колебаний в передаче.The elastic twisting of the torsion 5 also creates friction between the plates 6, which contributes to the damping of oscillations in the transmission.

Выполнение упругой зубчатой муфты с составным торсионом обеспечивает поглощение муфтой большей части энергии за счет трени между пластинами составного торсиона; применение ее дл передачи больших крут щих моментов. Расположение упругого элемента по оси муфты исключает возникновение дополнительных изгибающих моментов на соедин емые валы и их подшипники. Муфта проста в изготовлении и монтаже. Надежность муфты в эксплуатации выражаетс в предотвращении аварийных ситуаций, св занных с разрушением упругого элемента, поскольку такое разрушение не приводит к разъединению муфты.The implementation of an elastic gear coupling with a composite torsion ensures that the coupling absorbs most of the energy due to the friction between the plates of the composite torsion; using it to transmit high torques. The arrangement of the elastic element along the axis of the coupling excludes the occurrence of additional bending moments on the connected shafts and their bearings. The clutch is easy to manufacture and install. The reliability of the coupling in operation is expressed in the prevention of emergency situations associated with the destruction of the elastic element, since such destruction does not lead to the separation of the coupling.
