GEO5 calculates dimensions, operation angle, velocity and acceleration of Maltese cross gears. GEO5 generates drawings of Maltese cross wheel and driving wheel 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.

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

Size of the Geneva mechanism can be defined either by external diameter of the Maltese cross or by center distance. Then enter width of slots and driving bolt diameter. Dimensions of arc segments used as locking device are calculated by GEO5, just enter minimum wall thickness at slots and clearance between arc segments of Maltese cross and driving wheel.

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

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

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

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

Drawing of Maltese cross, driving wheel, diagrams and tables can be exported as DXF- or IGES files, and opened in CAD. Layers, colours and text font can be configured in GEO5.

Maltese cross wheel, driving wheel, 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.

GEO5 provides help text and auxiliary images. Warnings and error messages occur if exceeding a limit. For every error message you can have a description and remedy suggestion.

Units can be switched between metric (mm) and imperial (inches).

GEO5 is available as 32-bit app or as 64-bit app for Windows 11, 10, 8, 7.
