Design of Internal Geneva Drives

(C) Copyright 2018-2019 by HEXAGON Software, Berlin


Calculation and Design of Geneva mechanism

GEO7 calculates dimensions, operation angle, velocity and acceleration of internal Geneva drives. GEO7 generates drawings of Maltese wheel and driving crank as DXF or IGES files to be used with your CAD software. The component parts can be generated as STL files, then printed on a 3D printer and assembled as functioning model of a Geneva mechanism.


Dimensions

Number of slots in the Maltese wheel may be 4, but also any number between 3 and 100.

Size of the Geneva mechanism can be defined either by crank length or by center distance between crank and Maltese wheel. Then enter width of slots and driving crank diameter. Dimensions of arc segments used as locking device are calculated by GEO7, just enter minimum wall thickness and clearance between arc segments of Maltese wheel and driving wheel.


Diagrams

Angle of rotation of the Maltese wheel as function of the driving crank as well as velocity and acceleration over one revolution can be shown as diagram.


Animation

Rotation of Maltese wheel and driving crank can be simulated on screen as animation.


Text Output

Input data and calculation results may be printed, saved as text file or HTML file, or exported to MS Excel via OLE interface.


Graphics Output

Drawings and diagrams can be printed on any Windows printer, or exported to CAD.


CAD Interface

Drawing of Maltese wheel, driving crank, diagrams and tables can be exported as DXF- or IGES files, and opened in CAD. Layers, colours and text font can be configured in GEO7.


STL Interface

Maltese cross wheel, driving crank, bearing plate and spacer sleeve can be generated as STL file and produced with 3D printer. This way you can assemble a Geneva mechanism with the printed parts, just to be completed with metal bolt and shafts.
