The design of
Variator has been based on our principals' wide knowledge of
mechanical friction drives and has enabled much higher horse powers
to be transmitted.
The Variator consists of on outer casing (D) and end cover (P) in
which the co-axial shafts (C and M) are mounted. These rotate in
Power is transmitted
from the input shaft through a pressure device (N) to the drive disc
(L) thence to a series of double conical drive rollers (A) which are
free to rotate on fixed inclined spindles (G).
The carrier (H) in which the spindles are located is held on the end
cover boss and is so arranged that is can be moved axially by means
of the rack (K) and pinion (J).
From the drive
rollers, power is transmitted to the outer ring (E) and pressure
device (F) and thence to the output shaft through the drive flange
Due to the geometry
of the power transmitting components, the input and output shaft
rotate in opposite direction
