Voith will debut its new BHS AeroMaXX technology for turbo parallel-shaft gear units at POWER-Gen Europe 2016 in Milan.
The German company said that the BHS AeroMaXX has inner housing and optimized sleeve bearings hat reduce power loss and oil consumption by 30 per cent or more.
“The solution has a passive-mechanical character and does not require any additional accessories. Operators profit from identical design standards, unchanged overall operating behaviour and maximum reliability.”
Voith said that due to the high pitch line velocities of up to 200 m/s, oil swirling and oil squeezing in the gear mesh account for a substantial part of the power loss of high-speed turbo gear units. It added that the BHS AeroMaXX technology reduces these losses by separating lubrication and cooling.
“An inner housing in the direct vicinity of the gear set absorbs heat and dissipates it into the bottom area on the external surface on the inner housing via cooling oil. This means that a substantially smaller volume of oil is required for the actual lubrication of the teeth contact surfaces and the swirling oil/air mixture is minimized.”
The BHS AeroMaXX is designed for high pitch line velocities in connection with medium to high powers that, for example, occur in the driveline of power plants with compressors and generators. In such applications, Voith said the technology can be retrofitted in already installed gear units during standard maintenance of the driveline, without additional downtime.
POWER-GEN Europe and Renewable Energy World Europe is taking place in Milan from 21-23 June. Voith is at Booth 3HD128.
