Title:
MOTION CONVERSION MECHANISM
Document Type and Number:
WIPO Patent Application WO/2019/160452
Kind Code:
A3
Abstract:
The invention relates to mechanical engineering, and more particularly to devices for converting non-uniform rotational motion into uniform rotational motion and vice versa. A motion conversion mechanism comprises a housing, a common shaft, and a symmetrical differential reduction gear. The mechanism further comprises two rings for differential power flows, two cams having an inner working surface, and two cams having an outer working surface, and also two sliders with fingers. The profile of the cams having an inner working surface is described by the polar radius as a function of the polar angle and is an equidistant curve which is distanced outwardly from a first-order derivative of a basic closed curve by the size of the radius of a finger. The profile of the cams having an outer working surface is described by the polar radius as a function of the polar angle and is an equidistant curve which is distanced outwardly from a second-order derivative of a basic closed curve by the size of the radius of a finger. In a single revolution of the shaft, each ring performs two half revolutions back and forth. The result is smooth operation.
