Variable Speed
INSTALLATION GUIDE
HOW TO INSTALL BELTS
Take special care during the installation of variable speed
belts to avoid damage to the belts and sheaves. You may
have to open variator sheaves fully to facilitate installation.
You may also have to shorten the drive center distance to
allow for easy installation. You may have to remove sheaves,
as well. After assembly, return the drive center distance to
normal and recheck drive alignment.
TENSION
Spring loaded sheaves, which apply the tension required
to handle the design load, govern variable speed belt
tensioning.
BELT GUARDS
Belt guards ensure cleanliness and safety. Screened,
meshed, or grilled guards are preferable because they
allow for air circulation and heat escape. Note: Refer to
www.osha.org.
IDLERS
Idlers are not recommended for variable speed drives.
