Abstract

FIELD: mechanical engineering. SUBSTANCE: invention is designed for steplessly changing transmission ratio at high transmitted power, including stopping of driven shaft under load and reversing. Proposed variable-speed contains input and output shafts installed on bearings in housing, three-shaft differential, drive mechanisms, gear ratio change handle, two carriages with rollers, counterweight mounted on shaft rotating at angular velocity equal to that of input shaft, its center of mass, being located in antiphase relative to common center of mass of carriages. Shaft of carrier of three-shape differential composes integral unit with output shaft. Gear fitted on two other shafts of differential are furnished with drive mechanisms to impart rotation with relative 90o phase shift. Each drive mechanism includes two overrunning clutches rigidly coupled with differential gear by driven clutch members, and with input shaft by driving clutch members by means of cam and rollers to transmit oscillatory motion to driving clutch members with variable swing changed by gear ratio change handle. EFFECT: simplified design, reduced cost. 10 dwg

где mпр и mк - массы противовеса и каретки;
Rпр - радиус вращения центра масс противовеса;
ρcp - средний радиус вращения общего центра масс кареток.
High-torque variator, comprising input and output shafts mounted on bearings in the housing, a gear shift knob, a three-shaft differential, the carrier shaft of which with the satellite makes up a single link with the output shaft, and differential wheels coupled to the satellite are fitted with the possibility of communication on two other shafts rotational motion to a relative phase shift of 90 actuators, each of which includes an input shaft mounted to the cam, the two freewheel clutches with driven half couplings kinematically rigidly connected to the differential wheel, and driving ones with an input shaft, by means of rollers in contact with the cam, with the possibility of transmitting oscillatory motion to the leading coupling halves with an oscillation range that varies from the handle of changing the gear ratio, characterized in that it is equipped with input axes perpendicular to the axis shaft and mutually perpendicular guides with two carriages with rollers, as well as a counterweight mounted on a rotating with an angular speed of rotation ulachka shaft, for example, on the input shaft, so that its center of mass located in the opposite common center of mass of the carriages, and the relation
m CR R CR = 2m to ρ cp ,
where m CR and m to - the mass of the counterweight and the carriage;
R CR - radius of rotation of the center of mass of the counterweight;
ρ cp is the average radius of rotation of the common center of mass of the carriages.
