Toothed 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.
Synchronic toothed clutch 1
Input is blue shaft with which pink male cone disk has sliding joint.
Output is green gear (having face teeth) with which orange female
cone disk has sliding joint due to three bolts.
To connect the clutch move the pink disk to the right (via the grey
shifter). At first it makes the orange disk and the green gear rotate to
some extend due to friction at cone surfaces to ease teeth
engagment proccess after.
Planetary clutch
The orange gear is input. The violet carrier is output.
Using the pink screw to hold or release the internal gear, hence to let the
output carrier rotate or pause.
When the internal gear is released, the system has two degrees of
freedom. However the load at the output carrier keeps it immobile to
eliminate one.
Worm gear clutch 1
There is an eccentricity between the rotary axis of orange worm
and the one of the grey bracket.
Teeth on the worm and on the wheel must be rounded to ease
the engagement process.
Positioning device for the bracket is not shown.
The clutch connection should be done when the driving shaft
stops
Double Cardan joint (not shown) is used for transmitting motion to the worm.
Worm gear clutch 2
Turn pink lever (having an eccentrical pin) to raise or lower left
end of the orange shaft thus to connect or disconnect the clutch.
Teeth on the worm and on the wheel must be rounded to ease
the engagement process.
Positioning device for the lever is not shown. The clutch
connection should be done when the driving shaft stops
Instead of bevel gear drive, double Cardan joint can be used for transmitting motion to the
worm.
This idea is taken from US patent 20110247440 A1.
Rack gear clutch 1
Input: pink crank that rotates continuously.
Output: yellow gear shaft that oscillates.
Use green lever to close or disclose the clutch via orange cam.
The mechanism is used in washing machines.
Friction clutch 1
The orange shaft is driving. The clutch is connected by the spring
force (manual force is possible).
Positioning device for the violet lever at the clutch’s disconnected
position is not shown.
Friction clutch 2
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.
Friction clutch 3
Multiple-disk clutch.
The orange shaft and the yellow cylinder are driving. The two
orange outer disks are slidingly splined in the yellow cylinder.
The green shaft is driven. The blue part and the two green inner
disks are slidingly splined on the green shaft.
The clutch is connected by the spring force which presses inner
disks and outer disks together through the blue part (manual force is
possible).
Positioning device for the white lever at the clutch’s disconnected position is not shown.
Friction clutch 4
Cone clutch.
The orange shaft is driving. The clutch is connected by the spring
force. To step on the white pedal to disconnect the transmission.
Friction clutch 5
Blue elastic bush is fixed on the yellow driven shaft by a pin.
Pink bush carrying red wedge has sliding key joint with the yellow
shaft. When the pink bush moves to the left, the red wedge
expands the elastic bush. The latter goes into contact with the
inner cylindrical surface of the green driving shaft thus connects
the clutch by friction.
Belt clutch 1
The blue pulley is driving The orange one is driven.. The green
one is idle.
To rotate the pink crank to move the yellow slider for clutch
controlling.
Belt clutch 2
The orange pulley is driving. The yellow one is
driven..
Using the blue lever to move the orange pulley closer
to the yellow pulley to stop the transmission.
The violet lever is for braking the driven pulley when
it stops or rotates back under the lowered object’s
weight.
The red spring is for returning the violet lever.
Centrifugal clutch 1
Input: blue shaft.
Output: green shaft.
Yellow sliders have prismatic joints with the input shaft.
When velocity of the input shaft increases to prescribed value, the
yellow sliders move outward by centrifugal force, press on the inner
surface of the output shaft and thus connect the clutch by friction.
Centrifugal clutch 2
Input: green shaft.
Output: blue shaft.
The brown friction disk has prismatic joint with the blue output shaft.
When velocity of the input shaft increases to prescribed value, because
of centrifugal force the yellow arms push orange pins of the pink disk
towards the brown friction disk and thus connect the clutch by friction.
Centrifugal clutch 3
Input: blue shaft.
Output: green shaft.
Yellow sliders have prismatic joints with the input shaft.
When velocity of the input shaft increases to prescribed value, the
yellow sliders move outward by centrifugal force. Pink friction disks
press on the output shaft disks with large force (due to toggle action
of the grey bars) and thus connect the clutch by friction.
Centrifugal clutch 4
Input: blue disk.
Output: green disk.
Yellow levers have revolution joints with orange pins of the input disk.
When velocity of the input disk increases to prescribed value, because
of centrifugal force the yellow levers engage with teeth of the output
disk and thus connect the clutch.
