DRIVE ARRANGEMENT FOR TRAMMING CONVEYOR

摘要

A sprocket (26) drive system for a chain conveyor comprises a motor (15) driven transmission which is coupled to a planetary gear unit (16) for speed reduction. The output sprocket (26) is located near the center between the motor (15) and the planetary gear unit (17). To make the combination more compact in size and efficiency, the drive from the motor (15) is transmitted by means of a shaft (48) coaxially through the drive shaft of the planetary gear unit (17) and through the drive shaft of the transmission unit (35). The coaxial shaft (48) is then coupled to the transmission unit (17) input shaft (36). The transmission output shaft (38) is coupled to the planetary gear box and then to the drive sprocket (26).
