Angled worm gears for NEMA23 motors The HFOS gears are a series of inexpensive, very compact worm gears. By means of an adaptor Kit they can be mounted directly on motors with a NEMA23 standard flange, such as the MAC050-141 series of integrated AC servo motors and QuickStep integrated step motors. They will however also find applications with a wide range of common stepper motors with NEMA23 flanges. These gears offer the advantage over planetary gears that they by nature are angled and gives a very short total length of motor plus gear. The gears can be delivered both right- and left-angled as well as with output shaft to both sides. A wide range of gearing ratios, from 6:1 to 75:1 are available. When ordering, various worm and cogwheel materials can be chosen in order to optimize the gear for the application. On the output side the gears can be delivered with a 30 mm machined recess for centering and 4 M5 threaded mounting holes. A mounting fixture is available for mounting of the motor-gear combination • Gear ratios from 6:1 to 75:1 • Small build-in length, appx. 73 mm • Inexpensive solution for many less demanding applications • Adaptor kit for NEMA23 flanges • Can be adapted to customer application • Simpel and robust design
