METHOD TO DETERMINE REDUCED MOMENT OF INERTIA FOR MOVABLE MACHINE LINK AND A DEVICE TO IMPLEMENT IT Russian patent published in 1994 - IPC

FIELD: measuring equipment. SUBSTANCE: inertia mass 1 of thin thread device receives a part of kinetic energy of machine links. J₂ moment of inertia of device movable parts is known. ω₁ driving link angular speed before operation controlling device and ω₂ angular speed of the link and inertia mass 1 at the moment of their operation are measured. Desired reduced moment of inertia J₁ of the machine is determined on the base of law of conservation of momentum. Controlling device includes inertia mass 1, recorders of machine and inertia mass 1 angular speed, friction clutch 8 to switch on inertia mass, control aid in the form of switching 21, and freewheel clutch 15 to connect machine drive with main shaft. EFFECT: determination of reduced moment of inertia. 2 cl, 3 dwg
