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.
Applications example:
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
