FRICTION TYPE DAMPER FOR MOTOR, SCANNER DRIVE MECHANISM, SCANNER DEVICE, AND IMAGE FORMING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a friction type damper for a motor, preventing the fly of wear debris of the friction type damper without a cost increase. SOLUTION: The friction type damper comprises a steel case 33 mounted on a rotating shaft 70 of the motor 9, a permanent magnet inertial body 31 arranged in the case 33, and a skid material 32 of a predetermined friction coefficient arranged between the case 33 and the inertial body. The skid material forms a labyrinth gap between the inertial body 31 and the case 33 in a passage communicating an arrangement position with the outside. COPYRIGHT: (C)2006,JPO&NCIPI
