Features

Internal Freewheels FD are sprag freewheels without an inner ring. The customer s hardened and ground shaft is used as the inner track. The freewheels FD are used as:

Backstops

Overrunning Clutches

Indexing Freewheels

The standard type and 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 outer ring by press fit.

Application example

Two Internal Freewheels FD 40 CFR of standard type with bearing support as overrunning clutches in the drive of the transport rollers in a packaging distribution unit. In normal oper ation, the transport rollers are driven by means of the freewheels that are working in driving operation. At the withdrawal station, the arriving packages can easily slip off as the drive is overrun by the freewheel (freewheeling operation).

 

Mounting

Internal freewheels FD in type standard 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 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.

The permissible operating temperature of thefreewheel is - 40°C to 80°C.

 

 

Lubrication

An oil lubrication of the specified quality must be provided.

Main products

 

1. One Way Bearing

alternative RINGSPANN high quality R&B brand FD12 sprag freewheel roller chain

1. Overrunning clutch

for multiple-machine drives or to separate the iner-tia of masses of a driven machine from the driving machine after it has been switched off.

2. Indexing clutch

which turns a shaft step by step, thus achieving indexed material feed or a variable speed.

3. Backstop

to prevent a machine shaft turning backwards. In this case the overrunning clutch acts as a brake

 

2.Needle roller bearings

Applications:

 

Backstop

A Backstop application is where rotation

is allowed in one direction and stopped in

the opposite.

Application examples:

· Conveyor equipment

· Mixers

· High voltage switches

· Furniture industry

· Turnstiles and revolving doors

· Geared motors

· Winches

· Elevators

· Cranes

· Strap/belt tighteners

· Bucket conveyors

· Belt reversing locks

· Fans

· Automatic doors (subway)

· Fire damper flaps

· Aviation technology

· Roller plants

· Summer skiing

 

Indexing clutch

A repeated drive then idle motion will

be transferred to the driven side, step by

step, as rotary motion in one direction (the

clamping direction).

 

Application examples:

·Paper processing (advance)

· Seeding machines

· Staplers (staples)

· Conveyor belts (drive)

· Ratchets

· Ratchet wrenches

· Roller advance

· Installation tools

· Automation technology

 

 

Overrunning clutch

If the speed of the driven side exceeds the

speed of the driving side,the freewheel-clutch disengages the driving and driven sides by switching from torque transimit to idle.

Application examples:

·Copier machines

· Printing machines

· Conveyor equipment

· Transport equipment (speed matching)

· Starters for combustion engines

· Ergometers

· E-bikes

· Bicycle hubs

· Starters

· Emergency power aggregates

· Generators

· Hybrid applications (E-mobility)

· Palletizing and storage systems

· Model helicopters

· Hand operated sirens

· Roller coasters

· Washing systems

· Continuous ovens

· Compressors

· Compensating gearboxes

· Gas turbine drives

· Pump drives

· Belt drives

· Wheelchairs
