Calculation of chain gears to ISO 606


ZM1 calculates dimensions of chain gears according to ISO 606 and strength of chain gears according to Niemann/Winter. Roller chains can be selected from the data base provided.


ZM1 searches the data base and suggests an appropriate chain based on transmission ratio, power and drive speed. ZM1 determines the next even number of links for the chain and calculates the exact dimensions based on the approximate center distance.


The required chain is selected from the data base. ZM1 calculates the dimensions for chain and sprockets from the number of teeth of the sprockets and of the approximate center distance.

Strength Calculation

ZM1 calculates the static and dynamic breakage safety margin as well as the safety against permissible surface pressure. ZM1 determines the standard value of the joint surface pressure for roller chains. The life expectancy (Lv) of the chain is calculated according to Niemann.


Roller Chains to ISO 606

ZM1 calculates single, double or triple roller chains. The data base supplied with the program contains the dimensions and strength values for all sizes in accordance with ISO 606. Furthermore, chain gears according to the withdrawn standards DIN 8187 and DIN 8188 can be selected and calculated by means of a second database.


Loss of power and degree of efficiency are calculated from the joint friction coefficient and dimensions.


ZM1 determines the recommended type of lubrication from the diagrams for selecting type of lubrication (according to Niemann). The operation point of the calculated gear is shown in the chart.


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 the sprockets can be displayed on screen, printed out or exported as scale drawings to CAD via DXF or IGES interfaces.

Manufacturing Drawings

ZM1 generates production drawings of the sprockets. The drawing includes a header to ISO 7200 and an index of alterations taken from the program.
