FIELD: transport.SUBSTANCE: operation of the chain drive in underground opening whereat the coupling is arranged between drive engine and engine drive chain to transfer the required torque from said engine to the sprocket. Said coupling allows the adjustment of transferred torque. Note here that the torque transferred by the coupling at the drive engine start is set to the maximum magnitude and is decreased only after the engine preset rpm is reached.EFFECT: efficient and reliable prevention of the chain breakage in underground opening.5 cl, 4 dwg |
