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.
