Description

Freewheel clutches (overrunning clutches) are designed to prevent the transfer of torque from the driven shaft to the driving shaft when the driven shaft starts to rotate faster than it should be or in the opposite direction.

Thus, overrunning clutches are used for the purpose of connecting and disconnecting the transfer of forces when changing the parameters of rotation, transforming the reciprocating motion into a continuous translational motion, etc.

These features allow the use of overrunning clutches in lifting and transport equipment, mining, food, energy and other industries.

Examples of their application include preventing the rollback of conveyors and chains, connecting and disconnecting gears from motors, protecting mechanisms from overloads and inertial movement, ensuring shaft rotation in the presence of several motors, when some are working, others are not, and in other cases.

Ringspann offers an extensive range of overrunning clutches:
