Product Description

Internal Freewheels FDE
for press fit on the outer ring
with sprags, available in three types
Internal Freewheels FDE are sprag freewheels with anti-friction bearing dimensions.
The freewheels FDE are used as:
 Overrunning Clutches
 Indexing Freewheels
The standard type and the type with P-grinding for increased service life and indexing accuracy do not have bearing support. In the case of the standard type, every second sprag has been be replaced by a cylindrical roller; this freewheel can accept radial forces. Nominal torques up to 2 400 Nm. The torque is transmitted on the inner and outer ring by press fit. Bores up to 95 mm.

Application example
Two Internal Freewheels FDE 65 CFP, type with P-grinding, as indexing freewheels in the spring drive of a high-voltage switch. The contacts of high-voltage switches must be separated from each other within a few milliseconds upon shut down. The abrupt opening is achieved by a pretensioned spring. When this is triggered the contacts are pulled apart from each other. After the switch is switched back on, the release spring is retensioned. This is executed by a
camshaft that drives two indexing freewheels. This turns the shaft of the release spring at a
specified angle in small steps. The solution with indexing freewheels replaces a more expensive reduction gear. The P-grinding type ensures an increased service life and considerable indexing precision.
Internal freewheels FDE in standard type and type with P-grinding are without bearing support.
Concentric alignment of inner and outer ring must be provided by the customer. The permissible run out (T.I.R.) must be observed. The torque is transmitted on the inner and
outer ring by press fit. In order to transmit the torques specified in the table, the outer ring
must be accommodated in a housing with an external diameter K. The housing is made of
steel or grey cast iron in minimum quality GG- 20. When using other housing materials or smaller external diameters, we urge you to contact us regarding the transmissible torque.
The tolerance of the housing bore D must be ISO P6 and the tolerance of the shaft must be
ISO p6. The permissible operating temperature of the freewheel is - 40°C to 80°C.
An oil lubrication of the specified quality must be provided.
