Differences between assembly and actual test of hardened gear reducer

One of the key problems in the gearbox of hard tooth surface reducer is the inner ring fault caused by axial crack of rolling bearing. Turbine performance is achieved by quenching and carburizing materials. This shows that through hardened bearing development recommendations / WECS and failed axial cracks, while carburized bearings do not. Field experience shows that carburized bearing has low carbon core bearing, high nickel content, large residual compressive stress, and high amount of residual austenite, which provides higher fracture resistance and makes carburized bearing more durable than quenched bearing in wind power environment.
Hardened reducer
A hardened gear reducer is used to study how to assemble and reassemble the same test settings to affect measurement. The extension of torque loss between one component and another of the same test installation was observed. Rig conditions also affect the propagation of input torque. To understand how torque loss propagates changes due to assembly, test results can distinguish between changes due to differences between assembly and actual testing.
As an example of the advantages of this approach, consider an application that requires a ratio of 40:1. To achieve this ratio, all gears require three gears and four bearing sleeves. In general, the estimated efficiency of this hardened gear box will be 91% at 1750 rpm at full load. The overload capacity of the gearbox of this hardfacing machine will be scored with a unified service factor of 200% (catalog level). Instead, a worm gear system with the same ratio will require only two gear sets and two or three sets of bearings. (via helical gear mounted on motor shaft).
