Replacement worm gears for coal pulverisers
Renold Gears specialises in providing replacement worm gears for coal pulverisers, at coal fired power stations, and has a replication programme to provide interchangeable replacements for existing coal pulverisers installed worldwide. The coal pulverisers at power generation plants grind the coal to a fine dust before it is mixed with warm air and blown into the furnace where it ignites in a similar way to if it were a gas.
The replacement worm gears can be manufactured to the Renold gear form or reverse engineered from original parts. The company is also expert in producing high-quality custom-made worms and worm wheels. In the production of worm gearing the Renold gear form is widely respected for its performance and reliability in a wide variety of applications such as coal pulverisers.
Renold supply huge centre distance worm gears with up to 54" (1220mm) gearing centres. Each gear set is manufactured using the highest specification, centrifugally cast, bronze alloy worm wheel rims to ensure maximum tooth strength.
Worm shafts are manufactured from high-quality alloy steel with the threads case hardened to produce a uniform, hardened thread flank with a precision-ground finish. The gear teeth are hobbed to a predetermined backlash and lead correction for each size of mill.
