Geometric Modeling and Fatigue Strength Simulation of Bevel Gears with Variable Radius Tooth Root

open access: yesJixie chuandong, 2022
Aiming at the problem that most of the teeth root of straight bevel gears adopt fixed radius fillet transition with 0.3 times of modulus, which tends to to cause large bending stress on the tooth root and reduce the service life of bevel gears, a design ...

A 3D Printing Strategy for Hard Curved Surfaced Circuits: From Materials to Applications

open access: yesAdvanced Science, Volume 12, Issue 36, September 25, 2025.
Conventional PCB etching (multi‐step) and indirect transfer techniques fail to meet structural electronics’ demands for lightweight, miniaturized, and customized manufacturing. 3D‐printed conformal circuits enable direct integration of conductive traces into substrates or onto surfaces, achieving integrated structural‐functional fabrication.

直齿锥齿轮齿廓圆弧修形

open access: yesJixie chuandong, 2007
In order to minimize the fluctuation of gear transmission error and combined torsional mesh stiffness, tooth profile modification with circular curve was developed for involute bevel gears. At the same time it must ensure the variation of the load appear

Research on Gear Box Fault Diagnosis Technology Based on PCA‐EDPSO‐BP Neural Network

open access: yesIET Collaborative Intelligent Manufacturing, Volume 7, Issue 1, January/December 2025.
This paper takes the gear of the gearbox as the research object, and uses the deep learning model to analyse the gear operation data to realise the intelligent diagnosis and prediction of gear faults. ABSTRACT As a key transmission component, the gear failure (such as broken teeth, wear, pitting, etc.) of the gearbox can easily lead to equipment ...
