Lohmann + Stolterfoht (L+S) has a long and respected history in the development and manufacture of high-performance gearboxes, primarily for:
● Marine Propulsion Systems: Including main propulsion drives, thruster drives, and auxiliary gearboxes.
● Industrial Applications: Such as mining, cement production, and other heavy-duty industries.
● Mobile Applications: Gearboxes for Mobile machinery such as Mining Shovels and Haul Trucks.
The high loads and often continuous operation in marine and industrial settings can accelerate bearing wear.
Gear teeth can experience wear, pitting, or breakage due to stress, misalignment, or lubrication issues.
Worn or damaged seals can result in lubricant loss, contamination (especially in marine environments), and accelerated wear.
Improper installation or external forces can cause shaft misalignment, leading to vibration and premature wear.
Problems with flexible couplings (like those in the Spiroflex series) can affect power transmission and lead to vibration.
