Abstract
In the article the geometric determination of curvature radius is considered for teeth with cycloid profile. The equations are obtained for the determination of a radius of curvature with point coordinates of a cycloid profile. The conditions of convexo-concavity of a teeth profile are defined for transmission with intermediate rollers.

Summary
Strict requirements are imposed at balance of wait – dimensions - power for modern mechanisms and technical unit more-and-more. On the base on transmissions with intermediate rollers (TIR) reducers has optimum ratio of technical data. The rollers transfer loading by the angle of 180ْ. It allows transferring torque more than 5-10 times and repeated shot-time overload in comparison usual toothed gear transmissions. One of representatives of TIR is coaxial flat transmission with intermediate rollers, which is showed on Figure 1. The transmission works following way: motor rotates plant carrier H and the planet carrier made rollers to move radial in grooves of separator 2, as shows on Figure 1. The rollers contact with cycloid profile of central gear 3.
