More Information
Summary:In a roller type transmission device (1), an array (11) of transmission pin rollers is press fit circularly into an inner side surface (10a) of a stationary ring (1 0), and an array (18) of controllable pin rollers is press fit circularly into an inner side surface (13c) of a rotational ring (13). To pin rollers (11a, 18a), employed are high precision cylindrical rollers or needle rollers which are usually used for a roller bearing or the like. Such is the structure that the array (11) of transmission pin rollers and the array (18) of controllable pin rollers work as inner teeth to make a backlash phenomenon minimum, rendering a pitch distance precise between the pin rollers, maintaining a uniform tooth profile with a high precision, equalizing a surface roughness and improving a meshing precision between the pin rollers (11a, 18a) and the teeth (7a, 8a).
