TCG（Trochoid cam gear）
High performance rack arranged trochoidal tooth form in a straight line. By Koyo combining the two on pin provided with a roller which is a rolling contact with the tooth surface, I realize the rotation over linear motion by rolling completely, allowing nimble maneuverability and positioning with high accuracy in non-backlash.
High performance gear disposed circumferentially trochoidal tooth profile similar to cam rack. By combining the pinions on which is provided a roller which is a rolling contact the tooth surface, I realize the movement transmission by rolling full, and facilitates a light rotation transmission and positioning with high accuracy in the backlash.
By the bearing support on both sides a roller which engages with the trochoidal tooth profile, light rotation and positioning with high accuracy in the backlash – rotation, rotation – allows for linear motion transmission.
