Design and Investigation of an Asymmetric Logarithmic Spiral Gear Drive
Applied Bionics and Biomechanics, Volume 2022, Issue 1, 2022., 2022 Sliding on gear teeth working surfaces has negative effects on the performances of gears, such as tooth surface wear, pitting, etc. In order to reduce the gear sliding during high speed and heavy load, a new type of pure rolling gear, named as an asymmetric logarithmic spiral gear, is designed referring to the characteristics of the Issus planthopper ...

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 ...

Parameter based definition of eccentric cycloid gearings
Forschung im Ingenieurwesen, 2023 AbstractCurrent challenges for today’s industry are an increase in gear ratio in one stage, an increase in load capacity as well as an increase in efficiency compared to standard gears. The standard tooth profile for cylindrical gears is an involute. This tooth profile has certain limits for external gearings regarding its geometry, e.g., undercutting ...

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.

Deformation Investigations on the Flexspline with the Conic Curve Combined Cam Wave Generator
Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 The deformation of the flexspline and the meshing quality are largely determined by the profile of a wave generator. The wave generator with a combined profile can effectively reduce or improve the deformation stress and strain of the flexspline for improving the transmission efficiency and reducing wear or noise.

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.

Shock and Vibration, Volume 2021, Issue 1, 2021., 2021 Compared with dual‐mass flywheel (DMF) and DMF with simple‐type centrifugal pendulum vibration absorber (CPVA), DMF with bifilar‐type CPVA has a better damping performance in the whole speed range of engine. The related research mainly focused on local models, such as dynamic model of DMF and dynamic model of CPVA, and the effect of the curvature path ...

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.
