FIELD: engines and pumps.SUBSTANCE: flywheel unit comprises bulky flywheel resting by its upper and lower surfaces on the balls. Said flywheel is rigidly secured at the bush fitted on the shaft with the help of fasteners. Circular grooves following the shape of said balls are made at the bush end surfaces. Independent bulky separators with grooves separating the support balls are arranged in the flywheel top and bottom zones. Said balls can revolve free at the expense of the other two groups of balls fitted in two circular grooves on the separator inner surface.EFFECT: disengagement of flywheel at uncontrolled rotor acceleration, ruled out heating of balls, their contact and skidding.2 dwg |
