Abstract: The way of the high speed and energy saving technology on comber is reducing inertia force, movement speed and acceleration of parts on comber. With mechanical design optimization method, The separation roller system and nip plates transmission on HC350 type of comber is optimized to reduce the velocity and acceleration of parts on HC350 comber, and the HC500 comber are developed. Compared HC500 comber with HC350, the nip plate velocity valley value and acceleration peak value were reduced by 31.3% and 33%, the movement velocity valley value and the acceleration peak value of detaching roller were reduced 15% and 50% respectively. We are experiment on HC500 and HC350 comber and the result shows that HC500 comer has good high-speed performance and power saving effect.

Key words: comber, high-speed performance, power consumption, optimization design
