HOISTING AND LOWERING DRIVING ENGAGEMENT MULTI-ROW CHAIN

摘要

the entire chain of the present invention is achieved by adjusting the weight balance of the blood and lift the weight of the chain width direction to improve the load balance in, piseung river raises stably to the upper position the chain improves the durability, to realize the miniaturization of the reduction, the chain size of the driving noise and the internal toothed plate and the intermediate toothed plate chain width direction biased for its object to provide a coupling multi-row chain for the lifting drive to suppress. ; coupling multi-row chain for the lifting drive of the invention To this end 100 is inside the tooth plate 110 and the bush (120 ) and the mold of the intermediate toothed plate 140 and the outer tooth plate 150 and provided with a connecting pin 160, the inner tooth plates 110 and the intermediate toothed plate 140 and the outer tooth plate 150 is the same shape punching and processing, respectively from the same direction by, and is connected to the internal toothed plate 110 and the intermediate toothed plate (140) and a status at least one chapter, the rest plate and the inside and outside the other hand the external toothed plate (150). ; lifting chain, tooth plate, weight balance,
