Liebherr Wind Power Main Bearing Product Inheritance and Innovation-Single Row Tapered Roller Bearing

“ Turning one into two - Make one into two ”

Liebherr Wind Power Main Bearing Family Adds a Strong Member——Single-row tapered roller bearings。Liebherr as a strong technical partner，Take advantage of single row tapered roller bearings——More compact size for same fan capacity、Lighter weight、Lower torque effect，It provides a product more suitable for the current wind power market environment for major wind power main engine factories.。

Liebherr is now able to offer the wind power industry

Provide single row tapered roller main bearings

As more partners choose this main bearing layout，Liebherr Components is doing its best to meet customer requirements.。A set dedicated to wind power、The main bearing configuration consisting of two single-row tapered roller bearings has been successfully launched under the division of labor and cooperation of various departments.，This special layout is under our unique design.，It brings the best rolling characteristics and ideal force distribution to the bearing.。Through detailed finite element analysis and calculation during the development process,，Selection of precisely manufactured rolling elements、Strict machining tolerances are established to achieve precise preload in the installed state。The complete set of single-row tapered roller bearings manufactured based on the above technology realizes ideal load distribution.。

Complex and ingenious production process：

Induction Hardening Heat Treatment and Superfinishing

“Soft-belt-free induction hardening process requires extremely high positioning accuracy of induction equipment”Head of Technical Sales, Liebherr Components, Biberach, GermanyStefan MilotzkeExplain：“Liebherr has more than 60 years of experience in induction heat treatment of bearings.，This experience has enabled us to work perfectly with the four inductors of the soft belt-free induction heat treatment equipment。This is particularly important.，Because it can not only ensure that our final products meet the requirements of raceway surface hardness and hardened layer depth.，And the process stability of mass production is guaranteed.。”

Superfinishing can further refine the surface of the raceway。In the process.，The surface of the raceway is machined to a degree close to a mirror surface.，This can effectively reduce the wear of bearings.、Reducing the energy loss during rolling and improving the lubricating effect of the grease。This technology gives our main bearing products extremely high surface quality and longer service life.。
