Diagnostics of cycloidal gear speed reducers in vertical multirotor system / [PDF]

, 2017
This paper deals with failure diagnostic problems of vertical axis rotating machine driven by ten cycloidal gear reducers with high coupling ration. The cycloidal gear drive is not back drivable device and in case of only one cycloidal drive failure from

Analysis of Flow Characteristics of Straight Conjugate Crescent Gear Pump at Variable Working Conditions

Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
The working conditions (i.e., gas content, working pressure, and working temperature) of oil in the actual hydraulic system are always in a dynamic process, which will cause the basic properties of oil (i.e., density, absolute viscosity, and effective bulk modulus) to change and further generate changes of the flow characteristics in the straight ...

The Computational Fundamentals of Spatial Cycloidal Gearing [PDF]

, 2009
The tooth flanks of bevel gears with involute teeth are still cut using approximations such as Tredgold’s and octoid curves, while the geometry of the exact spherical involute is well known. The modeling of the tooth flanks of gears with skew axes, however, still represents a challenge to geometers.

Research on adaptive cruise control algorithm considering road conditions

IET Intelligent Transport Systems, Volume 15, Issue 12, Page 1478-1493, December 2021., 2021
Abstract As one of the most important ADAS systems, traditional adaptive cruise control is only suitable for relatively simple working conditions such as expressways, and it is difficult to deal with complex traffic environment and road working conditions.

3D-printable low-reduction cycloidal gearing for robotics

2022 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2022
The recent trend towards low reduction gearing in robotic actuation has revitalised the need for high-performance gearing concepts. In this work we propose compact low-reduction cycloidal gearing, that is 3D-printable and combined with off-the-shelf components.

Parametric Design on Internal Gear of Cycloid Gear Pump with NX10.0 [PDF]

IOP Conference Series: Materials Science and Engineering, 2017
The parametric equation of the theoretical contour curve of cycloid gear was established in this paper. Using the NX10.0 software, parametric design of cycloidal gear profile curve was carried out, and the radius of curvature with the contour curve of cycloid gear was analyzed.

Conservation and management implications of genetic and geometric scale variation in the ancient fish giant featherback (Chitala lopis)

Journal of Fish Biology, Volume 109, Issue 3, Page 1558-1580, September 2026.
Abstract Giant featherback (Chitala lopis) is an ancient species of freshwater fish considered globally extinct until extant populations were re‐discovered in the Sundaland region of Indonesia in 2022. To improve management of the remaining populations, this study used genomic DNA and landmark‐based geometric morphometric analyses of fish scales to ...

Reduction of gear pair transmission error with tooth profile modification [PDF]

, 2008
The gear noise problem that widely occurs in power transmission systems is typically characterised by one or more high amplitude acoustic signals. The noise originates from the vibration of the gear pair system caused by transmission error excitation ...

Fold Walker: An Origami‐Inspired Quadruped Robot for Multipattern Locomotion and Object Grasping

Advanced Robotics Research, Volume 2, Issue 1, February 2026.
This article presents Fold Walker, an origami‐inspired quadruped robot capable of multipattern locomotion and object grasping. With each leg featuring two rotational folds, the robot can transform from a flat 2D configuration into complex 3D poses. Furthermore, its trunk and legs can be one‐shot 3D printed as a unified structure, greatly simplifying ...

Generating Cycloidal Gears for 3D Printing

CoRR, 2016
(Shortened version of abstract in article itself) This article describes an algorithm for producing, for any desired resolution and any desired numbers of wheel and pinion teeth, polygonal approximations to the shapes of a pair of cycloidal gears that mesh correctly. An Octave implementation of the algorithm, mostly written in 2014, is included.
