robot servo motor flange

Description

One problem with connecting shafts to metal servo motor output gears is that the screw connection is axial. The metal output gear is placed directly on the pinion shaft via internal gearing and screwed centrally with a screw. If we now want to screw our own gear onto the output gear in the axial direction, the screw heads will reach the outer edge of the output gear and therefore a printed output gear is only possible if the diameter of the base circle is larger than the diameter of the gear. If the outer diameter of the tooth circle is to be as large as the diameter of the output gear, a different solution with an axial torque coupling is required.
The design that Tim Lueth invented for the servo motor already exists in a very similar form under the name guide pot with detent disc from the company Ganternorm. It can also be used with a spring element between the detent discs for coupling if no magnet is used. In contrast to Ganternorm, however, the routine can design any size.

This construction consist of a
a) guide pot (Führungstopf GN187,1)
b) Locking plates (Rastscheibe GN187.4)
c) Locking plates (Rastscheibe GN187.4)
d) Standard gearing (module 1, 19 teeth)
