Description of planetary gear system
The equipment uses the following three planetary gear systems:
- Sun gear 24/90 ("B" in the figure given on the previous page) and its planet gears
- Sun gear 65/60 ("K") and its planet gear
- Sun gear 24/28 ("O") and its planet gear
This section describes the planetary gear system of sun gear 24/90 ("B"). It consists of sun gear
24/90, two planet gears 34, arm A, and arm B as shown below.
Planetary Gear System
If the motor rotates, sun gear 24/90 rotates so that the rotational torque is transmitted to the
engagement between the sun gear and planet gears 34. Since the arms and planet gears are so
designed that the moment of the arms is less than that of the planet gears, the arms turn around
the center shaft in the same direction as sun gear 24/90.
If the planet gear(s) becomes engaged with any other gear so that the arm cannot turn furthermore,
the rotational torque of sun gear 24/90 is transmitted to that planet gear. Accordingly, the planet
gear starts rotation in the opposite direction of sun gear 24/90.
