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 ...

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.

Simulation Research on Trapped Oil Pressure of Involute Internal Gear Pump
Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 The main structure of an internal gear pump consisted of an internal gear pair, including an internal gear and an external gear. The internal gear pump had oil trapping phenomenon like other hydraulic gear pumps. In order to solve the oil trapping phenomenon of involute gear pump with internal meshing tooth profile, in this paper, the mathematical ...

TEETH GEOMETRY AND CONTACT PRESSURE CALCULATION OF EXTERNAL CYCLOIDAL GEARS [PDF]
Scientific Journal of Silesian University of Technology. Series Transport, 2018 Cycloidal (also called epicyclical or convex-concave) gears are used less often than common involute gears, which are very easy to manufacture and can be modified by corrections to the gear profile.

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.

Quantitative correction method for the grinding errors of cycloidal gears in precision reducer
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2020 The motion accuracy of a precision reducer mainly depends on the transmission quality of the cycloid-pin gear, which is determined by the grinding accuracy of the cycloidal gear. The poor meshing characteristics caused by grinding errors in the cycloidal
