Analysis of Geneva mechanism using dwell symmetrical coupler curve mechanism

Materials Today: Proceedings, 2021
Abstract Conveyor belt is a dedicated machine which is used in transporting the goods in assembly line area. This machine is driven by using a single mechanism for an operation. Here the focus is on the Geneva wheel which is used for this respective operation.

The pure-rolling cam-equivalent of the Geneva mechanism

Mechanism and Machine Theory, 2006
Abstract This paper deals with the kinematic synthesis of a pure-rolling cam mechanism kinematically equivalent to a conventional Geneva mechanism. This mechanism was designed as composed of a primary and a secondary mechanism, which work in parallel to produce an indexing motion on the driven link, identical to the wheel of the Geneva mechanism ...

Two Station Geneva Mechanisms

Journal of Mechanical Design, 1994
A conventional Geneva mechanism must have at least three radial slots (stations). This paper shows that it is possible to design a Geneva mechanism with only two slots, provided that the shape of the slot is not a straight radial line but a curved line. The design procedure of the two slot Geneva wheel is outlined in this paper.

Multistage Geared Geneva Mechanism

Journal of Mechanical Design, 1979
Design concepts for an n-stage geared Geneva mechanism, which is an assembly of n Geneva mechanisms connected by (n−1) gear trains, are proposed in this paper. The dwell time produced by the system is a function of (n−1) phase angles, the combined number of slots on all the wheels and the number of pins on all cranks in the system.

Analysis and Synthesis of Mechanical Error in Geneva Mechanisms—A Stochastic Approach. Part 1: External Geneva Mechanism

Journal of Mechanical Design, 1982
Because of error of manufacture and assembly, the output kinematic characteristics of a Geneva mechanism will be different from the desired ones. In this paper an analysis procedure is developed to find the error in acceleration and jerk of external Geneva mechanisms from the view-point of probability theory.

Analysis and Synthesis of Mechanical Error in Geneva Mechanisms—A Stochastic Approach. Part 2: Internal Geneva Mechanism

Journal of Mechanical Design, 1982
Because of error of manufacture and assembly, the output kinematic characteristics of a Geneva mechanism will be different from the desired ones. In this paper an analysis procedure is developed to find the error in acceleration and jerk of internal Geneva mechanisms from the viewpoint of probability theory.

Kinematic Analysis of Flexible Geneva Mechanisms

Transactions of the Canadian Society for Mechanical Engineering, 1988
The deformation of Geneva wheels resulting from a unit normal unit force applied at the point of contact between the driving pin and the wheel is determined using the finite element method. The dynamic and static forces driving the Geneva wheel, and wheel deformations are computed. The output of the flexible Geneva wheel is determined with the help of

Design of Geneva Mechanism with Curved Slots

Applied Mechanics and Materials, 2013
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 employed to derive an analytical description of the profile of the curved slots with and without an offset feature.

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.

Geneva Mechanisms Connected in Series

Journal of Engineering for Industry, 1975
Two suitably matched Geneva-wheels driven in series are proposed to convert uniform rotary motion to intermittent rotary motion. The suggested mechanism is simple, and its kinematic characteristics are very desirable. The output motion starts and ends with zero acceleration. The acceleration increases gradually at the beginning and ends smoothly at the
