Gearboxes are critical to the performance of many machines, from vehicles to wind turbines. Hydrodynamic bearings in gearboxes improve this performance by minimizing friction, extending service life and significantly increasing power density.
Find out how Miba bearings in gearboxes can achieve this.
Gearboxes must function reliably in many applications under extreme conditions. Hydrodynamic bearings can increase the performance of gearboxes and extend the application limits in a wide range of industries.
Miba relies on hydrodynamic bearing technology for gearboxes. They work hydrodynamically. A lubricating film between the bearing and shaft separates the two surfaces. This reduces friction and extends the service life. You can find out more about our plain bearings on our axial and radial plain bearings product pages.
For planetary gearsets in main gearboxes, Miba develops flexible solutions made of steel backing, bearing metal and coating. This reduces the installation space of the hydrodynamic slide bearings in the gearbox to just a few millimeters and enables higher power densities.
Bearing metals that can withstand the high temperatures and requirements can be applied directly to the friction surface (inner diameter of the gear wheel) by means of sputter coating. This can reduce the overall weight.
This application utilizes Miba bearings in the gearboxes, which ensure high speeds, effective vibration damping and rigidity. Depending on the requirements, the bearings can be designed with tilting pads.
With the flexible bearing solution consisting of steel backing, bearing metal and coating, the installation space can be reduced to just a few millimeters, thereby achieving higher power densities.
The use of Miba hydrodynamic bearings in various gearbox applications has achieved impressive results.
This results in up to two thirds less ground noise. Aircraft can land at airports for longer in the evening as the reduced noise development leads to a noticeable reduction in noise levels. Emissions are also reduced - CO2 by 15 % and NOx by 50 %.
Overall, it can be stated that, depending on the application, hydrodynamic bearings can increase the performance and reliability of the systems.
Thanks to the hydrodynamic mode of operation, the bearing also enables low-maintenance use and a long service life.
Hydrodynamic bearings are an enormous benefit for gearbox applications in wind turbines, aircraft turbofans, turbomachinery and off-highway vehicles. Hydrodynamic bearings
Thanks to their space-saving design and flexible design options, hydrodynamic bearings help to reduce energy costs and increase machine performance.
