INDOFAB driveheads are specially designed for compatibility with scraping mechanism used in Clarifiers, Thickeners, HRSCC and similar equipments. Their robust design of mounting and overload protection system has been developed exclusively for Industrial and Wastewawter applications where inlet load is fluctuating.
These Drives are typically made of CS or Graded Iron Worm Wheel resting on a large size Bearing (Steel Balls & Bearing Strip Liners forming a bearing cage) driven by Alloy Steel Hardened worm fixed to the Worm Shaft. The EN8/EN19 Worm shaft is driven & coupled by suitably selected Gear box & Motor. The Worm Shaft, Worm, Worm Wheel with all bearings, Adaptor & Thrust collar are Splash Oil Bath Lubricated in a Gear Housing & Top covered with a housing cover. The gear housing & cover are typically shaped to give large base & easy foundation holes, Oil Indicator, Oil Drain, Inspection Cover & Seals / gaskets to be put in place.
