环形链条的价格便宜,任意方向的挠性好,允许轨道有较小的垂直弯曲半径,轻巧美观,是悬挂输送机较为理想的牵引件。但是由于环形链条的制造误差较大,磨损较快,积累起来的节距误差使原来传统的链窝链轮与环形链条的啮合传动寿命短,有时几乎不能传动;另外,由于猫头吊(或称滑架)与环形链条的活连接接头使得链窝链轮须去除一部份齿形与链窝,从而产生传动与猫头吊节距安排上的麻烦。由于有以上两方面的麻烦,环链在悬挂输送机上并没有得到广泛的应用。
The price of the ring chain is cheap and flexible in any direction, allowing the rail to have a smaller vertical bending radius, which is light and beautiful, and is an ideal traction component for the hanging conveyor. However, due to the manufacturing error of the ring chain is relatively large and the wear is relatively rapid, the accumulated pitch error makes the transmission of the conventional chain sprocket and the endless chain to have a short transmission life and sometimes can not be driven at all. In addition, Said the carriage) and the endless chain of live joints make the chain sprocket to remove part of the tooth profile and the chain nest, resulting in transmission and cat head hanging pitch arrangement trouble. Due to the above two troubles, the endless chain is not widely used on the hanging conveyor.
