Description

In doing so, the flywheel 6 rotates clockwise. The rollers 14 are not enclosed, and the flywheel 5 does not rotate.

When operating in the second mode, the electric motor 12 is put into operation and rotation through the pulley 10, the transmission 9 is transmitted to the flywheel. When the handwheel 5 is rotated clockwise, the rollers 14 are wedged, as a result of which the handwheel 6 also rotates clockwise. When clutch 7 is turned on and brake 8 is turned off, rotation is transmitted to the crankshaft shaft 2. From the crankshaft shaft, through the rod 3, the movement is transmitted to the slider 4. By reciprocating, the slider 4 performs technological work.

When operating in the third mode, the electric motors 12 and 13 simultaneously turn on, the rotation of which through the pins 10 and 11, gear 9, the flywheels 5 and 6 with the clutch 7 turned on and the brake 8 off, is transmitted to the crankshaft 2. From the crankshaft shaft 3 the motion is transferred to the slider 4. The slider, moving reciprocatingly, produces technological work. At the initial moment of the press operation, the flywheel 6 lags behind the flywheel 5 (the flywheels 5 and 6 rotate clockwise), resulting in the rollers 14 becoming jammed, and both the flywheels, rotating in the engaged state, increase the torque by Krivoschipnom shaft 2 and the kinetic energy of the flywheel.

When operating in the fourth mode, the electric motor 13 is put into operation and rotation through the pin 11, the transmission 9 is transmitted to the flywheel 6. The rotation of the flywheel 6 is counterclockwise. In this case, the rollers 14 are wedged and the flywheels 5 and 6 are interconnected.

With the brake off, 8 jerks turn on the clutch 7, and the rotation is transmitted to the crank shaft 2. From the crankshaft shaft, through the rod 3, the movement is transmitted to the slider 4. This mode of operation can

be used when removing the press from the thrust.
