DRIVE SHAFT WITH DIRECT-MOUNTED SPROCKETS FOR FILTRATION APPARATUS

Document Type and Number:

WIPO Patent Application WO/2016/084516

Kind Code:

A1

Abstract:

An essentially maintenance-free drive shaft (55) with direct-mounted sprockets is disposed on a chain-driving unit (14) for driving a conveyor (13) of a filtration apparatus. The drive shaft (55) with direct-mounted sprockets is provided with a shaft body (60), a pair of metal plate sprockets (61, 62), and first mounded sections (71) and second mounded sections (72) that are obtained from weld beads. The first mounded sections (71) are formed at the respective corners formed by the two side surfaces (61b, 61c) of the first metal plate sprocket (61) and the shaft body (60), and the first mounded sections (71) are formed so as to alternate, changing position in the circumferential direction of the shaft body (60). The second mounded sections (72) are formed at the respective corners formed by the two side surfaces (62b, 62c) of the second metal plate sprocket (62) and the shaft body (60), and the second mounded sections (72) are formed so as to alternate, changing position in the circumferential direction of the shaft body (60). Torque that is input to the shaft body (60) is transmitted to the metal plate sprockets (61, 62) via the mounded sections (71, 72).
