SU1618960A1 - Pulsed speed-varying gear - Google Patents

Abstract

This invention relates to mechanical engineering, in particular, to variable continuously variable transmissions-variators. The aim of the invention is to expand the range of adjustment of the rotational speed of the driven shaft while maintaining the dimensions of the variator by another implementation of the mechanism for changing the rotational speed of the driven shaft. The mechanism for changing the speed is made in the form of a drive shaft 2 mounted on the splines with longitudinal protrusions, each of which has an end surface inclined to the axis of the shaft 2. In the eccentric washers 8, radial grooves are made, in which the protrusions of the bushing are placed, moving along the shaft 2, changes the eccentricity of the washers 8, the swing angle of the rocker arms 4 and the angular velocity of the driven shaft 3 11 or so change.

Claims (2)

Claim A pulse variator comprising a drive shaft, eccentric washers located on it, a driven shaft, freewheeling mechanisms installed on it according to the number of eccentric washers, rocker arms, connected at one end to the corresponding freewheel mechanisms, and the other to eccentric washers, and a rotation speed change mechanism driven shaft, characterized in that, in order to expand the range of regulation of the frequency of rotation of the driven shaft while maintaining the dimensions, the mechanism for changing the frequency is made in the form installed on the drive shaft with the possibility of axial movement of the sleeve with at least two longitudinal protrusions on its outer surface, in which the end surface facing the eccentric washers is inclined to the axis of the sleeve, and radial grooves are made on the eccentric washers to interact with the corresponding ribs.
