TechBlog #7 | The Influence of Bearing Selection on Gear Modifications

An important aspect of gearbox development is the practical design of gear modifications. The article will demonstrate the degree to which the selection of rolling bearings can influence the required gear modifications.

Design of Gear Modifications

Load-induced deformations and displacements in gearboxes can lead to significant gear mesh misalignment. This can cause uneven load distribution across the face width and greatly reduce gearbox safety factors. To avoid this scenario, gear modifications must be designed to compensate for these deformations. This requires detailed analysis of all gear deformations. The single-stage gearbox in Figure 1 will provide an example of how strongly the selection of the bearing type, together with the axial bearing design and bearing clearance, can influence gear modifications.
