Wittenstein Releases Compact, Zero-backlash Gearheads Engineering360 News Desk | April 28, 2015 German precision motion specialist Wittenstein has unveiled what it calls a new generation of compact, zero-backlash gearheads with independently movable teeth. Key tolerance per DIN 6885 is +0. When computerized gear design is considered, usage of tables requires a number of interpolations; usage of charts requires curve fitting; and usage of semi-analytical methods needs a numerical algorithm and may have convergence problems. The following are important features requiring tolerance specification to control backlash: runout in both gear and pinion (or worm), profile, pitch, tooth thickness, and helix angle. AGMA website. Manufacturing quality of gears makes a huge difference. This driving gear wheel has been installed in a medium-speed engine with backlash present at four different positions; with additional backlash checked on. For over 30 years, MITRPAK® right-angle drives have set the standard for reliable operation, often in extremely demanding environments.
