大家好压缩包里的文章和pdf的有些重复的 如果大家想下看看 就先下压缩包里的看少哪篇再下哪篇本人新手带来的不便 望各位好友谅解 好的！我先 下载 好的，谢谢了，太谢谢了 非常感激楼主 非常感激楼主 楼主辛苦了，上传这么多文件也挺费劲 好东西，谢谢楼主 回复 2# 北方钰泉觉得那些论文讲的都不是很详细，细节的地方没有写出来 Magnetic powder clutch by the transmission unit (input shaft) and driven unit (output shaft into the merger. In the space between the two groups of unit, fill a granular magnetic powder (Hugh about 40 microns) deposition. When magnetic coil nonconductive, torque transmission not from wonders in driven shaft, but if the coil electromagnetic electricity, because magnetic force function and attract magnetic powder produce sclerosis phenomenon, even after sliding between in the torque transmission.
Magnetic powder clutch is a kind of the superior performance of automatic control components. It with magnetic powder for medium for control means with exciting current, achieve control of braking or transferred major purpose. Its output in turn major and exciting current good linear relationship with speed or sliding and has nothing to do with fast response and simple structure, etc. Widely used in wire, cable, packaging, printing, paper and paper processing, textiles, rubber, leather, metal foil tape processing and other relevant coiling device tension automatic control systems. Magnetic powder clutch also used in the buffer starting, overload protection, speed, etc.

Magnetic powder magnetism gas characteristics, and poor powder mutual adhesion stability, sliding torque very stable, and the relative rotation several no relationship can abiding constant torque.
(4) continuous sliding operation use
Come loose hot effect excellent thermal deformation and adopt uniform cooling structure, plus the magnetic powder high heat resistance, allow links and braking power and sliding big power, can smooth sliding operation, and won't cause vibrations.
(5) link sleek, no impact
Links to the impact of the tiny, no impact on the smooth start and stop. And resistance torque is tiny, won't cause useless calorific value.
(6) suitable for high frequency operation
Response of quick and special quick cooling structure, suitable for high frequency operation use.
(7) lightweight, maintenance-free, long service life
The lightweight, use concise type of high-temperature coil and special grease bearings, and in the light of attrition easily impose wear-resisting armature and prolong service life special treatment.
