<p>The invention relates to a soft-actuated and moment-limited centrifugal ball coupling, which is mainly provided with several dampers on the spider shaft between the spider blades. Said dampers consist of 4 to 6 blocks each of which is secured to the spider shaft via a dish spring, or of 4 to 12 permanent magnetic blocks, magnetic leakage-proof pads therebetween and a hood which are secured to the spider shaft by a fastener. The advantages of the coupling according to the invention are fair arrangement, good soft-actuated performance, low friction, long service, wide applicability, high reliability and convenience for use and maintenance and so on.</p> |
