Planetary Gear Drive

The drive arrangement consist of electric motor a multi-stage planetary gear reducer and a single stage spur gear transmission. The electric motor is flanged-mounted to the input of the planetary gear reducer, which in turn is flange-mounted to the input of spur gear transmission. The hollow input of the spur transmission can be keyed directly on to the crystalliser shaft. The drive unit can be aligned in a convenient direction with respect to the crystalliser axis and its torque arm structure is to be bolted at the convenient place. No other additional structure, such as base frames or any couplings are required. The drive unit is completely enclosed & oil-tight. All internals including bearings are oil-lubricated, oil change is recommended only once a season.
