Freewheels Backstop One Way Clutch Bearing FXM 51-25 FXM51-25 FXM51

The FXM one-piece flywheel is equipped with an overrunning clutch. occur. Low speed During flywheel operation, centrifugal force F C causes the damper to lift off the outer ring. In this operating state, the flywheel is wear-free, ie has an infinite service life.

    The figure shows a flywheel with the takeoff X in the flywheel state. The slider is supported in a cage connected to the inner ring and rotates together with the inner ring. The centrifugal force F C exerted on the flange center of gravity S causes the flange to rotate counterclockwise and press against the support ring of the cage. This results in a space a between the skate and the outer ring; the flywheel works without contact. If the speed of the inner ring drops to the point where the centrifugal force acts on the slinger less than the spring force F F, the slinger will stop on the outer ring again and the flywheel is ready to lock. If used as an overrunning clutch, the drive speed should not exceed 40% of the starting speed.

    The maximum transmissible torque is 2 times the specified nominal torque.

    The theoretical nominal torque applies only for ideal concentricity between the inner and outer ring. In practice, the concentricity is affected by the bearing play and centering errors of the neigh bouring parts.

    Then the nominal torques specified in the table apply, whilst taking into consideration the existing run out (T.I.R.).Higher speeds upon request.
