Optimization of High Speed Geneva Mechanisms

Journal of Mechanical Design, 1981
This paper presents an analytical and computer-aided procedure on the optimum design of Geneva mechanism. The subject is treated in two parts. In Part I, a set of parameters is derived for evaluating the performance and determining the dimensions of Geneva mechanism suitable for high-speed operation. The effects of geometry on dynamics, stress, as well

The kinematic synthesis of a linkage driven Geneva mechanism

Mechanism and Machine Theory, 1982
Abstract A method of synthesis of a 4-bar linkage that generates a figure 8 coupler curve to be used for the driving pin of a Geneva indexing wheel is presented. Constraints are imposed on the design which force the results to be a crank-rocker mechanism and ensure that the indexing period starts and terminates with zero acceleration and has no ...

Double Crank External Geneva Mechanism

Journal of Mechanical Design, 1993
A designer specified motion characteristics can be obtained using the double crank external Geneva mechanism presented in this work. This mechanism basically consists of double cranks and double curved slots that work together in generating the desired output motion.

Design and Fabrication of Paper Cutting Machine Using Geneva Wheel Mechanism

INTERNATIONAL JOURNAL OF SCIENTIFIC RESEARCH IN ENGINEERING AND MANAGEMENT
—In many small-scale industries and workshops, paper cutting is still performed manually, which is time-consuming, labor-intensive, and less accurate. This paper presents the design and fabrication of a semi-automated paper cutting machine using a Geneva

Analysis and Synthesis Procedures for Geneva Mechanism Design

IBM Journal of Research and Development, 1966
This paper contains general analytical results which can be applied to high-speed Geneva design. The results are derived from classical mechanics theory and provide explicit relationships between the performance parameters (those parameters such as contact stress, maximum load, etc., which can have a significant effect on the mechanism performance) and

A New Interpretation for the Dynamic Phenomena Associated with Geneva Mechanisms

Journal of Mechanical Design, 1979
The basic Geneva Mechanism is one of the most widely used intermittent motion mechanisms. The classification of its dynamic characteristics is established in this paper to make feasible, meaningful comparisons with all other available mechanisms for the same task.

Development of a New Geneva Mechanism With Improved Kinematic Characteristics

Journal of Mechanical Design, 1991
A Geneva wheel with curved slots is proposed as an intermittent rotary motion generating mechanism. The proposed mechanism has vastly improved kinematic characteristics. Changing the slot shape from a straight radial line to a curved line results in the elimination of shock loading at the beginning and end of the motion cycles and reduces the wheel ...

Irregular Geneva-Wheel and Geneva-Slider Mechanisms for the Generation of Nonuniform Index Ratios During a Cycle

Journal of Mechanisms, Transmissions, and Automation in Design, 1986
The article deals with Geneva mechanisms driven with multiple cranks for the generation of multiple indexings with different index ratios during a cycle of motion. Both, Geneva-wheel mechanisms, and Geneva-slider mechanisms for the generation of rotary and linear motions with dwells, respectively, are considered.
