一、前言采用圆环链作牵引和承载构件的斗式提升机等设备,普遍用带链窝的链轮作驱动轮。对于取料头成刚性L型的链斗卸船机,由于要在圆环链上安装取料斗和支承滚轮,并且链斗运行轨迹较复杂,因此不能采用普通链窝式链轮,而必须使用齿形链轮作为驱动轮。这种结构在引进的1200t/h链斗卸船机上已被采用。交通部水运所研制了刚性L型链斗卸船机模型,图1为链斗运行轨迹。取料斗背部伸出四块特殊形状的支持板,板中间安装销轴,料斗与链条借助销轴相联,销轴一端安装支承滚
I. Preface The use of circular chain for traction and carrying components bucket elevator and other equipment, generally with a chain of sprockets for the drive wheel. For a rigid L-shaped chain bucket unloader with a pick-up head, since the hopper and the support roller are to be installed on the circular chain and the running path of the chain bucket is complicated, a normal chain-type sprocket can not be used and must be used Toothed sprockets serve as drive wheels. This structure has been adopted on the introduction of 1200 t / h chain bucket unloader. Ministry of Transportation developed a rigid L-chain bucket unloader model, Figure 1 is the chain bucket running track. The hopper back protruding four special shaped support plate, the middle of the plate to install the pin, the hopper and the chain linked by a pin, one end of the pin bearing ring installed
