Crank of a partition

Slider crank mechanism with satellite pulley

The diameter of the big pulley is double the one of the green pulley. The length of each crank = R The slider's stroke = 4R The belt should be toothed. It is possible to use chain drive instead of belt one. STEP files of this video: http://www.mediafire.com/file/frn0cmys8sedruy/SliderCrank

Gear and linkage mechanism 1

A slider crank mechanism of two conrods and two cranks. The latters are fixed to two gears in mesh. Owing to the symmetric arrangement the piston axle moves rectilinearly (even if no cylinder (the left mechanism)). Lateral forces from piston applied to cylinder are negligible. STEP files o

Folding door controlled by cable

The door consists of two slider-crank mechanisms. Driving parts are violet sliders that are brought into motion by a motor via a cable drive of two pink pulleys. Lower branch of the cable is fixed to the left slider. The upper branch is fixed to the right slider. Thanks to the eccentricit

Gear slider crank mechanism 1

The hole center on the orange lever reciprocates according the motion rule (the green closed curve) that differs from the one of a ordinary slider-crank mechanism. This mechanism is applied in wire drawing machines for guiding wire (in red) to its coil. STEP files of this video: https://

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
