VARIABLE SPEED DRIVES
-
The Accuspeed variable speed drive is a totally new concept in design and materials application. Accuspeed is intended for those industrial equipment applications requiring precise variable speed control and postive power transmission.
UNIQUE PULLEY DESIGN
Accuspeed utilizes a V-ribbed belt concept in combination
with modern materials technology to carry the traditional accuracy of
the expanding pulley to new performance standards. Th
ere are three major elements in the Accuspeed pulley design; a
face plate, 12 precision machined segments on which the belt rides, and
a cone. The face plate and the cone, which are the carriers for
the machined segments, are machined of an engineering polymer possessing
high tensile strength and excellent ductility. The grooves in the
face plate and the cone are precisely matched to accommodate the segments
and their keepers and permit free movement during the expansion and retraction
of the pulley surface.
OPERATING PRINCIPLE
Varying the position of the cone
in relation to the face plate causes the segments to move outwardly or
inwardly in the grooves of the face plate, thereby expanding or contracting
the surface of the pulley. This action is smooth, accurate and
stepless, assuring infinitely variable speed.
V-RIBBED BELT
Because the V-ribbed driving surface of the belt bottoms completely on the precision-machined pulley segments, maximum friction between the belt and the pulley is acheived, resulting in an extremely high load carrying capacity and positive power transmission. Belt tension is easily established and maintained. The quality of the belt used assures long service life.
