GENERAL INFORMATION
The following operating and maintenance instructions are
intended to help with general installation and maintenance
procedures.
It is presumed that system design, as well as all work with regard
to transport, assembly, installation, starting-up, maintenance and
repair, is performed by qualified personnel or supervised by
skilled labor taking overall responsibility.
BASIC OPERATION AND SPEED ADJUSTMENT
Titan

Adjustable-Speed Drives are ideal for use when operating
conditions dictate infinitely variable output speeds over a fixed
range. The Titan

Drive consists of a motor, belt casing, and
main gear drive.
The beltbox contains an Adjusting Pulley (Driver) that is attached
to the motor output shaft. A handwheel (or optional Electric
Remote Control) is used to vary the operating pitch diameters of
the driver pulley in-turn making a corresponding adjustment to the
Spring Pulley (Driven). Belt center distance remains fixed.
Speed is typically adjusted by loosening the lock nut handle on
the handwheel.
INSTALLATION
Titan

drive packages may be supplied with a variety of gear
units including foot-mounted, flange-mounted or shaft-mounted
options.
Complete drive packages may also be assembled in the
“U”-Flow or “Z”-Flow patterns as shown on Page 4.
When selecting the drive installation site, one should remember
that air-cooled motors are ideally designed for ambient
temperatures between -4°F and +104°F (-20°C and +40°C) and
for installation at altitudes of 3,300ft (1,000m) above mean sea
level.
The installation site should also ensure the following:
•
Unrestricted airflow over the motor and variable speed drive.
•
Accessibility to the oil fill-hole, level-hole and vent-hole
locations on the main gear drive.
•
A foundation (mounting base) of adequate size that is flat,
torsionally rigid, and vibration-proof.
•
Adequate shaft alignment between the drive and the driven
equipment.
•
Adequate space to allow motor removal and/or maintenance.
•
In cases where brake motors are used, fan guard removal
may be necessary to allow for brake adjustment and
maintenance.
MOTOR
Please reference the manufacturers Installation and Maintenance
Manual/s to obtain detailed instructions pertaining to the motor or
brakemotor.
Connect the motor in accordance with the wiring diagram
information supplied with the motor. Be sure the voltage supplied
to the motor is accordance with the rated voltage on the
nameplate. A protective motor switch is recommended to help
protect the motor windings from overload and/or phase failure.
To insure the same performance the replacement motor must be
of the same design and style as the original. The end of the
motor shaft must also have a tapped hole in it as shown below.

BELT CASING
Pulleys are manufactured from the corrosive resistant and
extremely durable alloy “Durfondal” to provide superior wear
resistance and assure grooving and wear will be minimized under
rated operating conditions. Pulleys are permanently grease
lubricated and should require no disassembly during the normal
life of the Titan
TM
drive. All sliding components are coated to
resist fretting and corrosion.
When operating in extremely dusty or dirt environments, an air
filter must be installed to the main housing vents to protect the V-
belt, pulleys, and coated shafts.
When operating in areas of higher ambient temperatures, or when
installed where ventilation is poor, additional cooling may need to
be applied to the belt housing.
The adjustment wheel spindle (511) must occasionally be cleaned
and lubricated to assure trouble-fee operation. Detailed
instructions concerning belt removal and pulley removal will be
covered in later sections of this manual.
WARNING:
LOCK OUT POWER before any maintenance is
performed. Make absolutely sure that no
voltage is applied while work is being done on
the drive.
WARNING:
Speed adjustments must be performed when
the motor is operational. Failure to comply
may damage the belt and pulleys.
WARNING:
Initial adjustment of the speed stops located
internal to the beltbox are completed at the
factory. Further adjustments of the speed
stops can cause damage to the beltbox and/or
main drive.
