2. 2. Principle of operationPrinciple of operation е Деталь 2 Деталь 1 Main principle: A fixation point A of an output Shaft (item 2) to the desired time In the right place movable the remaining points. Points O and M Are axes of rotation of the input Деталь 3 А Are axes of rotation of the input (item 3) and output shafts (item 3) respectively. Distance O-M is eccentricity of the variator and can change in the range of 0 to emax through mutual rotation of the Crank (item 1) and the input shaft (item 3). А CVT transmission ratio i = (R e) / e, where R - radius (distance Change of gear ratio i is due to changes in the eccentricity running at any rotation of an input shaft. The proposed principle uniform rotation of an output shaft. Principle of operationPrinciple of operation N O M (distance MN) pitch circle of the output shaft (part 2). eccentricity e. For e = 0 the output shaft of the variator is not principle provides unstressed fixation of point A and

5. 5. Operation parameters of drivesOperation parameters of drives Drives with frictional (belt) variators Works effectively in a range of angular velocities (ωmax/ωmin= 3–6). Efficiency is lower than in a mechanical gear. Drives with Moment Works most effectively in only a few points. Drives with MARS Works effectively in a wide range of angular velocity (ωmax / ωmin greater than 1000). Works effectively in creeping mode. Efficiency is comparable with the efficiency of a manual transmission. Drives with mechanical transmission Ideal drive Operation parameters of drivesOperation parameters of drives The dependence of the MARS efficiency and torque on the output shaft of the output speed and transmission ratio Works effectively in a wide range of angular greater than 1000).
