Control device, image forming device, wear detecting method, program, and storage device |
摘要 |
A control device includes a transmission unit including a first gear rotating with a motor shaft and a second gear rotating with a rotating roller which drives a rotated body, a speed detecting unit for detecting the rotational speed of the rotated body or rotating roller, a motor controlling unit for maintaining a constant motor shaft rotational speed based on the rotational speed, a converting unit for converting the rotational speed to a relationship between a frequency contained in a variation of the rotational speed in association with time and a variation value of the rotational speed, and a wear detecting unit for detecting a predictor of wear of cogs in at least one of the first and second gears when the variation value at a specified frequency, determined based on the number of the cogs of the first gear and the motor shaft rotational speed, exceeds a threshold value.
