Title:
摩擦伝動装置
Document Type and Number:
Japanese Patent JP4816093
Kind Code:
B2
Abstract:
A friction drive device transmits torque by frictional contact between rollers. The friction drive device includes a casing, a drive roller that is supported for relative rotation with respect to the casing, a driven roller that is supported for relative rotation with respect to the casing, a cam mechanism that presses the drive roller and the driven roller into contact with each other, and a damper. The cam mechanism includes a surface that is disposed at an angle with respect to a tangent of the contact between the drive roller and the driven roller, and includes a rotational support part that is disposed on the surface and supports one of the drive roller and the driven roller such that displacement along the surface by the rotational support part maintains the frictional contact for transmitting the torque. A damper reduces vibration of the rotational support part caused by torque fluctuation in rotational direction.
