b) Attaching the “A” Base Rotational Adapter Accessory to the RMS
The drive belt links the 3-
step Pulley mounted on the
“A” base to the 3-step Pulley
on the RMS. For a one-to-
one correspondence,
connect the two pulleys
using the o-ring on the
middle step of each pulley.
Each revolution of the
Rotating Platform or
Gyroscope corresponds to
one revolution of the RMS.
If desired, a 5-to-1 ratio can
be attained by putting the o-
ring on the top or bottom
steps.
The pulley attaches to the
underside of the rotating
shaft with the shoulder screw. Please note the pulley orientation
illustrated in Figure 13. The bracket connects to the “A” base of the
Rotating Platform or the Gyroscope and to the RMS rod clamp.
