FIELD: machine building.
SUBSTANCE: pulse variator consists of generator of mechanic oscillations, of regulating mechanism and of rectifying mechanism. The rectifying mechanism consists of summing and differential mechanisms, driven shafts of which are coupled with brakes (14, 14', 15, 15') by means of controlled transmission gears (17, 17', 18, 18') with varied gear ratio. The generator creates oscillating motion of driven links with trapezoid law of variation of their velocity and with phases successively set off relative to each other at a quarter-period and successively summed. By means of controlled transmission gears brakes operate at continuous torque under an optimal mode at any gear ratio of the variator; brakes operation is synchronised with generator operation.
EFFECT: increased reliability, service life and efficiency of variator.
