Wide Variable Speed Belts

-
Pulleys in the WB series use wide variable speed belts for the most efficient
transmission of torque through the widest possible speed range. These pulleys
are two-side moveable for the best possible belt alignment when used with a
grooved companion sheave. However, the location of the belt centerline close
to the bore end of the pulley reduces the overhung load on motor bearings and
seals. Precision-calibrated springs maintain correct pressure, keeping the belt
properly tensioned and minimizing belt slip.
WB pulleys can be used on both adjustable and fixed center drives. They offer maximum service when lubricated through a convenient grease fitting and occasionally run through the speed range.
Belt Selection
-
WB pulleys offer optimum speed ratios because they are used with wide
variable speed belts. Pulley flanges are designed to match standard belt angle
and width, so each pulley model must be matched to the correct belt to insure
full speed range and maximum torque capacity.
Adjustable Center Drives
-
The typical adjustable center drive consists of: the WB pulley mounted on the
motor shaft; a grooved

Adjustable Center Drives
-
The typical adjustable center drive consists of: the WB pulley mounted on the
motor shaft; a grooved companion sheave mounted with a bushing on the
driven shaft; an adjustable motor base; and a variable speed belt. A wide range
of pulley sizes and horsepower ratings are available from the WB series to fit
the system requirements, and Lovejoy offers the correct drive belt, companion
sheave, bushing, and motor base to complete the package.
Fixed Center Drives
-
Fixed center, or compound, drives offer greater driven speed ranges in a
compact space. A fixed center drive consisting of a WB spring-loaded pulley and
an adjustable pulley to match offers the best possible package for “C” mount
configurations where zero offset is critical. Zero offset means that the driver
and driven units are in line with one another, and the driven pulley is mounted
in such a way that the belt rides as close as possible to the driven unit. This
reduces overhung load and provides a smoother running drive. Three WB fixed
center drive packages are available, from 1/3 through 3 HP.
