Three-dimensional static meshing characteristic analysis and vibration reduction design of a double helical gear

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2021
Although axial free floating of the driving pinion can automatically balance the load of the left and right helical gear pairs, it causes its three-dimensional vibration.

From Green Governance to Biodiversity Strategy: The Role of Environmentally Experienced Directors in Chinese Firms

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study investigates how directors with environmental protection (EP) backgrounds influence corporate biodiversity concern (BIO) among Chinese A‐share listed firms from 2008 to 2023. Drawing on Upper Echelons Theory, we argue that directors' environmental expertise shapes firms' biodiversity strategies.

Remanufacturing the Pinion: An Application of a New Design Method for Spiral Bevel Gears

open access: yesAdvances in Mechanical Engineering, 2014
Damages of a large spiral bevel gear drive as used in heavy industry typically affect the pinion. Even if the gear still could be used, the complete pair has to be changed. This leads to long off times, high costs, and unnecessary waste.
