Jaw clutch
The orange shaft is driving. The clutch is connected by the spring
force (manual force is possible).
Positioning device for the pink lever at the clutch’s disconnected
position is not shown.
Ratchet clutch
The pink pawl connects the orange driving shaft to the blue driven one.
To rotate the green pin of helix slot for controlling the clutch.
Pin clutch
Clutch for small-size eccentric presses.
The big pulley rotates continuously. For connecting the clutch push
down the violet pedal to allow the pin come into contact with curve
slots on the pulley under the pink spring’s force.
The spring for return the pedal after pushing is not shown.
Keep pushing down the pedal to make the crankshaft rotate
continuously.
Rotary key clutch
Clutch for medium-size eccentric presses.
The big pulley rotates continuously. For connecting the clutch, step
on a pedal (not shown) to pull down the green slider. Then the pink
rotary key can rotate (under the red spring’s force) when it meets
the slot in the big pulley hole, thus makes the crankshaft rotate.
The green slider goes up to disconnect the clutch.
Keep down the pedal to make the crankshaft rotate continuously.
The small picture shows how the rotary key rotates in round hole
between the crankshaft and the big pulley when they are immobile.
One way clutch 1 (gear)
The blue gear is input.
A disengaging idler rises in a slot because of gear forces when
the drive direction is reversed.
The mechanism should be used only for low speed because of
gear collision.
One way clutch 3 (jaw)
The orange input shaft rotates two directions but the transmission
is possible for one direction only.
There is collision when the output green shaft stops, so the
mechanism should be used only for low speed.
One way clutch 4 (slider)
The pink input disk rotates two ways but the transmission to the
yellow disk is possible only for one.
The mechanism should be used for low speed because of collision.
One way clutch 5 (spring)
The cyan input shaft rotates two directions but the
transmission is possible only for one. The rotation
direction that tends to wind the spring is transmitted
to the yellow output shaft due to friction force between the spring and the shafts. For the
inverse direction the yellow output shaft may rotate if there is no braking force or load
applied to it.
The helix spring needs not be fastened at either end; a slight interference fit is acceptable.
The spring helix direction decides the transmission direction.
One way clutch 6 (spring)
The cyan input shaft rotates two directions but the
transmission is possible only for one by the pink
spring.
The rotation direction that tends to wind the pink
spring is transmitted to the yellow output shaft due to friction force between the pink spring
and the shafts.
The blue bush is stationary. The orange spring is for keeping the yellow output shaft
immobile when it stops.
The helix springs need not be fastened at either end; a slight interference fit is acceptable.
The spring helix direction is the key factor for this mechanism.
One way clutch 7 (helical gear)
The blue input shaft rotates two directions but the transmission is
possible only for one. The pink shaft moves longitudinally when the
input shaft reverses because of axial component of gear force in the
helical gear drive.
The mechanism should be used only for low speed because of gear
collision.
Face gear 14
One way clutch.
The blue input shaft rotates two directions but the transmission is
possible only for one. The pink shaft moves longitudinally when
the input reverses because of axial component of gear force in
the blue gear drive. The orange rings represent thrust bearings.
The mechanism should be used only for low speed case because
of gear collision.
