Traction drive has many advantages over a gear mechanism. For example, its backlash is negligible and instantaneous variation of reduction ratio is very small at any rotary angle. These advantages are attractive for high-precision servomechanisms that rotate at constant speed, such as NC gear processing machines. However, there has been little research reported on this subject so far. Thus, we developed a constant-velocity servomechanism that uses traction drive as its reduction mechanism, and carried out experiments to confirm its performance. Moreover, we propose torque compensation using slip-speed feedback to compensate the effect of torque disturbance and confirmed its usefulness by experiments. In this paper, the dynamics of the traction drive applied to constant velocity servomechanisms is introduced, and the method of disturbance compensation using slip-speed feedback is discussed. Then, details of the traction drive, control system and detecting systems are described, and the experimental results are presented.
