Machine unit operating conditions

The designed machine unit serves as the drive of the cradle elevator and can be used at enterprises in various directions. Drive consists of electric motor whose shaft is connected through elastic clutch to drive shaft of cylindrical reduction gear and open chain plate gear, driven shaft of which is drive shaft of elevator. The designed drive operates in 1 shift in non-revertive mode. The nature of the load is with small fluctuations.
