Product Detail

Features

Complete Freewheels FAV with lever arm are roller freewheels with sleeve bearings. They are grease-lubricated and therefore maintenancefree.

The freewheels FAV are used as:

➧Backstops

➧Indexing Freewheels

for applications with low speed freewheeling operation when used as a backstop or with a low to medium total number of actuations when used as an indexing freewheel.

Nominal torques up to 2 500 Nm.

Bores up to 80 mm.

Application example

Two Complete Freewheels FAV 50 in the roller feed of a sheet metal processing machine. The indexing freewheel arranged on the left is driven via a bell crank with an adjustable lift. This enables an infinite setting of the feed. The backstop arranged on the right prevents the indexing rollers from running backwards while the indexing freewheel carries out its back stroke. Often, an additional small brake is provided in order to prevent the accelerated sheet metal strip from advancing.

Mounting
When used as a backstop, the backdriving tor-
que is supported by the lever arm. The lever arm
must not be clamped into position. It must
have 0,5 to 2 mm play in the axial and radial di-
rections.
When used as an indexing freewheel, the lever
arm serves as the indexing lever.
The tolerance of the shaft must be ISO h6 or j6.
