Computerized generation and simulation of meshing of a novel crown gear coupling avoiding edge contact

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2019
To avoid the occurrence of the hub tooth tip edge contact with the sleeve tooth root flank and the sleeve tooth tip edge contact with the hub tooth root flank, a novel crown gear coupling composed of a hub with profile crowning, longitude crowning, and ...

Compliance error compensation in robotic-based milling [PDF]

open access: yes, 2014
The paper deals with the problem of compliance errors compensation in robotic-based milling. Contrary to previous works that assume that the forces/torques generated by the manufacturing process are constant, the interaction between the milling tool and ...

Tooth surface mismatch design of cycloidal bevel gear based on two directions modification of pinion cutter

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing
Aiming at the sensitivity of installation errors caused by the complete conjugated tooth surface of cycloidal bevel gear, a method of tooth surface mismatch design which only modified the pinion cutter along two directions was proposed.

The Tooth Contact Analysis of a Heavy-load Planetary Gearing [PDF]

open access: yesProceedings of the 5th International Conference on Advanced Design and Manufacturing Engineering, 2015
Keywords: Planetary gearing; Tooth contact analysis; Modal analysis; ANSYS Abstract. This paper presents a method for analyzing the tooth contact situations of a heavy-load planetary gearing based on Ansys Workbench. Firstly, a 3D finite element model of the whole gearing is established with 10 node tetrahedron elements.

A Semi-Analytical Load Distribution Model for Cycloid Drives with Tooth Profile and Longitudinal Modifications

open access: yesApplied Sciences, 2020
The current load distribution model for cycloid drives based on the Hertz contact stiffness typically assumes a two-dimensional planar problem without considering the tooth longitudinal modification effects, which fails to comply with the practical ...

Finite element modelling and load share analysis for involute worm gears with localised tooth contact [PDF]

open access: yes, 2001
A new approach has been developed by the authors to estimate the load share of worm gear drives, and to calculate the instantaneous tooth meshing stiffness and loaded transmission errors. In the approach, the finite element (FE) modelling is based on the

An Engineered Living Material With Pro‐Angiogenic Activity Inducible by Near‐Infrared Light

open access: yesAdvanced Functional Materials, EarlyView.
NIR‐responsive engineered living materials (ELMs) for controlled angiogenesis: Near‐infrared (800 nm) light activates engineered probiotic bacteria within alginate‐based living materials to secrete a blood vessel‐regenerating protein. The released protein promotes pro‐angiogenic effects in endothelial networks and chick chorioallantoic membranes.

Nano‐Engineered Titanium Implants Loaded With Gingival Fibroblasts‐Derived Microvesicles Enhance Early Osseointegration And Soft Tissue Attachment In Vivo

open access: yesAdvanced Healthcare Materials, EarlyView.
Our study showed that human primary gingival fibroblast–derived microvesicles on nano‐engineered titanium implants promote early osseointegration and soft‐tissue attachment in vivo. ABSTRACT Titanium dental implants require both reliable osseointegration and peri‐implant soft tissue seal formation to ensure long‐term success. While osseointegration has

Investigation of Load Sharing and Dynamic Load Characteristics of a Split Torque Transmission System with Double-Helical Gear Modification

open access: yesShock and Vibration, 2021
A new dynamic model for a two-input two-path split torque transmission system which considers meshing error, time-varying meshing stiffness, and meshing-in impact is proposed.
