Rotary key clutch 1b

Clutch for medium-size eccentric presses (25 to 45 tons). The large input pulley, which is idly mounted on the crankshaft, rotates continuously. For connecting the clutch, step on a pedal (not shown, same as the one shown in the video    • Pin clutch 1b  ) to pull down the cyan 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 cyan slider goes up to disconnect the clutch. In the final scene of the video, the outside end of the pink key is cut away to clearly show the interaction between the key and the pulley slot. Keep down the pedal to make the crankshaft rotate continuously. STEP files of this video: https://www.mediafire.com/file/eg0xhe...
