Multi-drive system for mining and tunnelling conveyors

摘要

A drive system for conveyors used in mining and tunnelling industries is equipped with several similar drive units (4,13) each comprising asynchronous motor (5), coupling (6), gearbox (7) and additional coupling (8) A controller/regulator unit (10,20) exerts overriding influence on drive units (4,13) and their couplings (6,7,8) which collectively embody decoupling facility operating in conjunction with chain drive of conveyor itself (2) During load take-up phase drive units (4,13) are able to transmit required torque independently of each other in stepped or continuous sequence
