Lifting chain type lifting chain
Lifting chain type lifting chain, also known as chip joint chain, lifting chain joints, etc., it is used for lifting device of the sprocket orchainb lock on the pulley, and other requirements of compact transmission of low speed and heavy loading. It has the advantage that the welding ring lifting chain, and work is more reliable. With chip lifting chain and sprocket instead of manual hoist wire rope and drum, the structure is compact. Its disadvantage is that the chain weight is bigger, only one-way flexible, not bending tendency, lubrication and maintenance difficulties. Installed in the Buddha mountain hydropower station of 100 tons 50 tons/double gate door leaf chain hoist type lifting chain structure. The chain consists of pin plate, gasket and cotter pin. In order to facilitate the chain of loading and unloading, and chain pin shaft can be made into optical axis, and put in the sleeve. Chain on the transmission of the friction wheel turned a tooth plate rotating Angle the schematic diagram of figure 2 is a chain. Figure in the drive chain wheel turned a tooth, the location of the plate, the rotation Angle. Chain to the position, the rotation Angle. Sprocket teeth when the driving chain wheel turned two teeth, dynamic sprocket turned a ratio of 2.
