Analysis of Geneva Mechanisms

Journal of the Society of Motion Picture Engineers, 1945
In the mechanical design of practically all types of instruments, it is necessary for certain parts to operate intermittently relative to a continuously moving part. A popular and simple means of obtaining this movement is by the use of the Geneva mechanism.

An improved Geneva mechanism for optimal kinematic performance

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2011
In this article, an alternative Geneva mechanism is presented and optimized. Unlike the original mechanism in which the driving pin operates at a fixed radius, the alternative mechanism benefits from a fixed groove cam which controls the radius of action of driving pin, resulting in continuous wheel acceleration and lower maximum velocity and ...

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

Computer Aided Design of Classic External Geneva Mechanism

Advanced Materials Research, 2014
Geneva mechanism is used as a mechanism for transforming rotary motion into intermittent motion and is able to achieve a precise movement and its lock, which makes it usable in many areas, particularly in timer devices, measurement devices, feed mechanisms, positioning mechanisms, pick-up and transport machinery, textile machinery etc.

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 ...

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

Synthesis of Combined Geneva Mechanism with Cycloid Crank

2011 Second International Conference on Digital Manufacturing & Automation, 2011
When the slot number of the geneva is fixed, the kinematic coefficient of common geneva mechanism is a fixed value, too. Using the cycloid production mechanism as the drive crank of geneva is equal to the mechanism with a variable length, variable velocity and along the cycloid moving crank, which makes the kinematic coefficient of the geneva mechanism

Improving Kinematic Characteristics of Geneva Mechanisms Using Variable Input Speed

Volume 7B: 26th Biennial Mechanisms and Robotics Conference, 2000
Abstract A method is proposed to improve the kinematic characteristics of the conventional Geneva mechanism. Rather than driving the input crank at a uniform speed, suitably changing the crank speed can not only eliminate the impact loading at the beginning and end of the motion cycles but also reduce the wheel peak velocity and/or the ...

DESIGN AND ANALYSIS OF GENEVA MECHANISM WITH CURVED SLOTS

Transactions of the Canadian Society for Mechanical Engineering, 2014
A simple yet comprehensive method is proposed for the design of a Geneva indexing mechanism with curved slots. In the proposed approach, conjugate surface theory is used to derive an analytical description of the profile of the curved slots with and without an offset feature.
