Brevini Posiplan gearboxes in Corus plan
Brevini has supplied 4 Posiplan gearboxes to Corus Scunthorpe steelworks; these hybrid gear units will be used to open and close doors on the iron desulphurisation process at its UK filter plant.
According to Brevini, the door drives needed to be compact, strong, durable, and able to provide high torque output and low energy input.
Brevini solution met all the application requirements: the Posiplan hybrid gearboxes combine the efficiency of low weight, high reduction ratios of planetary gear stages on the input side with the higher capacity, strength and durability of bevel helical gears on the output, suitable for medium to large sized industrial applications.
As well as reducing dust emissions, the new technology aimed to create a more pleasant working environment for employees and helped to speed up the steelmaking process. Doors have been designed that close to contain the fumes during the process while the extraction system draws them away.
The design of these ultra-compact gear units is based upon precise analyses using FEM (Finite Elements Method) techniques applied to 3D models, which means that performance, in terms of duration and silence, was optimized already in the virtual prototype phase.
The gearboxes are shaft mounted, making them suitable for applications that require 90 degree operation or survival in harsh environments. Finally, Brevini hybrid gearboxes use labyrinth sealing technology and high-performance bearings.
