ZM3 calculates dimensions of synchronous belt drives according to ISO 5296 (MXL, XXL, XL, L, H, XH, XXH), ISO 17396 (T und AT), ISO 13050 (G, H, R, S).

Predimensioning

ZM3 searches for a suitable synchronous belt drive by input of transmission ratio, power, speed.

Select your favorite belt profile and belt width. From pulleys number of grooves together with approximate center distance or belt length or belt number of grooves, ZM3 calculates exact center distance and other dimensions of synchronous belt and pulleys.

ZM3 calculates tangential force and permissible belt load and belt stress.

The calculation results and input data can be printed out on any Windows printer. Alternatively, ZM1 can generate an HTML or TXT file for editing with an Internet Browser or spreadsheet program.

Drawings of belt and pulleys can be displayed on screen, printed out or exported to CAD via DXF or IGES interfaces.

ZM3 generates true scale profile drawings of trapezoidal profiles to ISO 5296, ISO 17396-T, ISO 17396-AT. ISO 13050-H can be generated as trapezoidal profile with large radii. Profiles G, R, S according to ISO 13050 cannot be generated, these are approximated as trapezoidal profile.

ZM3 generates production drawings of the pulleys. The drawing includes a header to ISO 7200 and an index of alterations taken from the program.

CAD Export

ZM3 generates STL files of the pulleys with trapezoidal profile to produce models by means of a 3D printer.

An auxiliary text can be displayed for all entries. Auxiliary texts and diagrams can be modified and appended by the user. When error messages are shown, you can have a description and remedy suggestion displayed.

ZM3 is available as 32bit and 64bit version for Windows 11, Windows 10, Windows 7.
