3.1.2 Method of operation
(see Fig. 1 and Fig. 2 )
The three-phase AC motor (11BA) drives the mechanically adjustable variable speed pulley (1BA)
which drives the spring-loaded variable speed pulley (2BA) via the V-belt (3BA). This pulley is fitted
onto the driving shaft of the reduction gearbox (12BA). The variable speed pulleys and the V-belt are
covered by the housings (4BA and 5BA).
The speed is adjusted via the adjustment facilities (6BA, 7BA, 8BA), i.e. by turning the handwheel
or operating the adjusting motor to move the pulley flange of the mechanically adjustable variable
speed pulley (1BA) in the axial direction. The speed is indicated by means of the speed indicator in
the handwheel or a DC tacho or an impulse recorder and a display.
