A Simplified Method for Examining Profile Deviations of Conjugate Disk Cams
(The American Society of Mechanical Engineers (ASME), 2008)The profile errors of conjugate disk cams can be indirectly examined by means of measuring the conjugate condition of the assembled conjugate cam mechanism. This paper demonstrates how to measure ... -
Singularity-Free Joint Actuation in Omnidirectional Mobile Platforms With Powered Offset Caster Wheels
(The American Society of Mechanical Engineers (ASME), 2008)This paper presents the analysis of singularity and motion capability of a mobile platform articulated by offset powered caster wheels. Specifically, it presents the analysis of the equations ... -
Dynamic Transmission Error Prediction of Helical Gear Pair Under Sliding Friction Using Floquet Theory
(The American Society of Mechanical Engineers (ASME), 2008)An analytical solution to the dynamic transmission error of a helical gear pair is developed by using a single-degree-of-freedom model with piecewise stiffness functions that characterize the ... -
Noncircular Bevel Gear Transmission With Intersecting Axes
(The American Society of Mechanical Engineers (ASME), 2008)Noncircular bevel gear can achieve variable transmission between intersecting axes. Based on polar coordinates, a design method for noncircular bevel gears is presented. The geometric characteristic ... -
Analysis of Rotational Precision for an Isosceles-Trapezoidal Flexural Pivot
(The American Society of Mechanical Engineers (ASME), 2008)An isosceles-trapezoidal flexural pivot can be of great use for practical designs, especially in the cases that a pure rotation about a virtual pivot is required. The analysis of rotational ... -
Generation of Epicyclic Gear Trains of One Degree of Freedom
(The American Society of Mechanical Engineers (ASME), 2008)New planetary gear trains (PGTs) are generated using graph theory. A geared kinematic chain is converted to a graph and a graph in turn is algebraically represented by a vertex-vertex adjacency ... -
Modified Disturbance Function Method for a 6-6 Gough–Stewart Parallel Manipulator to Traverse the Singularity Hypersurface
(The American Society of Mechanical Engineers (ASME), 2008)Due to the motion uncertainty at the singular point, while the manipulator traverses the singularity hypersurface and moves from one singularity-free region to another, its motion is uncertain. ... -
A Class of Parallel Robots Practically Free of Parallel Singularities
(The American Society of Mechanical Engineers (ASME), 2008)This paper presents a class of 6-DOF three-legged parallel robots that are practically free of parallel singularities. The robots of this class have legs with a characteristic passive pair of ... -
