A ship that transported gypsum required a new solution for their bucket elevator. Previous gear units were leaking oil, due to the gypsum environment degrading the output seals. In addition, bolts were ´popping´ due to the high axial and radial loads being experienced.
A solution was proving difficult, especially given the small envelope size required.
The Solution: Brevini´s S-Series Gear Unit, plus In House Local Engineering Design.
First, Brevini´s design engineers visited the ship and completely measured the available space. They then produced a customised design to meet the unique application requirements.
Four drives were supplied, consisting of a custom designed foot-mount gearbox with a special input including a one-way bearing.
A special output sealing arrangement was also designed, consisting of labyrinth o-rings and a double-lipped seal.
The bolts on the keeper plate drive flange were upsized, to adequately bear the loads of this demanding application.
The resulting solution delivered high torque, high axial & radial load bearing capacity, all within a small envelope size.
