Gear transmission is a major form of power transmission, of which the reliability greatly
affects the life of many mechanical devices. Gears have two main failure modes, namely …

This paper studies the dynamic response of a wind turbine gearbox under different
excitation conditions. The proposed 4 degree-of-freedom (DOF) dynamic model takes into …

Optimising the hob used to manufacture gears is an attractive approach for minimizing the
gear tooth root stress. However, currently available approaches often require modifying the …

High contact ratio gears are used to minimize the stresses generated on the tooth surface.
This research article represents an idea to enrich the contact strength of gear drive using …

The most common gear strength calculations performed in accordance with ISO/TC 60/SC 2
include surface durability and root bending strength. Typical geared power transmissions …

A generalised non-dimensional multi-parametric model for involute spur gear design is
presented, considering manufacturability and geometrical compatibility, where the latter …

This paper proposes an original method to determine the gear tooth root stresses from a 3D
finite element (FE) flexible multibody approach and a full-FE contact-based formulation. The …

A precise estimation of the bending and contact stresses, as well as the true friction value
during the gear mesh, are critical aspects of a cost-effective and safe gear design. Previous …

Strength research is always one of the study focuses of face gear drives. However, a
strength calculation solution, in which bending stresses, contact stresses, and bulk …

In this paper, a two-dimensional computational model is proposed for predicting the initiation
position and propagation path of subsurface crack of spur gear tooth flank. In order to …
