A database suited to this purpose is one that uses dBase format or the integrated The materials used for making gears can be selected from a database and transferred to ZAR1. Spur gears can be generated as STL files and manufactured by means of a 3D printer. Planetary gear train and a sectional view of the tooth action can be displayed on the screen or output as a CAD drawing. A single tooth, the tooth space, the complete gear, gear-generating tool, The tooth shape with involutes and envelopes can be calculated precisely and plotted out in CAD. ZAR1 generates drawings of the front and side elevation of the gears calculated, plus tables containing the You can execute an animation of the gear tooth contact.ĭXF and IGES interfaces allow ZAR1 to be linked to CAD and DTP systems. In the case of internal gear and planetary gear trains, the internal gear can be shown rotating within the ring gear. The tooth shape can be displayed graphically by means of simulation using the gear-cutting tool. Simply input transmission ratio and number of stages.Īll input data and results can be output clearly on the screen or on a printer. ZAR1+ calculates pre-dimensioning for multistage gears. To enable users to optimize gear trains with extra-depth gearing, the program allows the tool dimensions of normal and protuberance profiles to be defined freely, with and without The load-bearing capacity with respect to tooth root fatigue fracture and pitting can be calculated in conformance with either DIN 3990 / ISO 6336 Parts 1 to 3 or DIN 3990 / ISO 6336 Part 41 (Vehicle Pinion/rack gears can be calculated by setting number of teeth for gear wheel 2 higher than 1000. Tooth thicknesses, backlash, chordal dimension over two teeth, diametral dimension M over balls and over pins, and all permissible errors in conformance with DIN 3961 and DIN 3962. On entering the gear quality and tolerance zone, the program also calculates the gear data, Once the user has entered the pressure angle, helix angle, normal module, the numbers of teeth, facewidth and addendum modification coefficients or the center distance, the programĬalculates all the important geometrical data, tool dimensions and contact ratio factors.

ZAR1+ generates STL files for 3D printing of the gear wheels. The program contains appropriate interfaces for linking it to CAD systems and databases. The ZAR1+ gear calculation program calculates the geometry and strength of externally and internally toothed straight spur and helical gears with involute toothing as well as rack-pinion gears in conformance
