Philadelphia Gear's Synchrotorque line includes hydroviscous
drives for variable output speed and torque control, as well as
clutching, braking and load absorbing. Products are available in
horizontal and vertical configurations as both stand-alone assemblies
or with built-in step-up or step-down gearing. Equipment enhanced
by use with Synchrotorque include pumps, compressors, fans, conveyors,
test stands, crusher drives, mill drives and marine propulsion drive
Because Synchrotorque products have 100-percent lockup capability, they offer significant energy savings over other variable speed device types that operate with fixed slip losses. This energy savings represents a significant reduction in lifecycle cost. And now, with the advent of the Mark VII Controller, Synchrotorque technology has taken another step forward.
Synchrotorque hydroviscous drives operate by shearing
an oil film to transmit torque - transmitting in proportion to a
variable clamping force. For unrestrained loads, the higher the
clamping force, the faster the output speed. The input driveplate
functions as the driver, and the output friction disc is faced with
a suitably grooved resilient material, acting as the driven member.
Precisely controlled clamping pressure between input drives, plates
and output friction discs allows for virtually infinite speed control
right up to 100-percent of input speed. This is the basis for controlled
torque transmission in the Synchrotorque drive.
By combining the hydroviscous clutch and gearing in
a common housing - the Synchrotorque Gear-Pak - several
economies can be realized:
Major drive components eliminated
Reduced foundation cost
Reduced total equipment initial cost
for Horizontal Applications
Synchrodrive for Horizontal Applications is ideal for
obtaining variable speed or soft-start capability with
existing equipment by locating the Synchrodrive between
the existing prime mover and the load device.
for Vertical Applications
Synchrodrive for Vertical Applications is ideal for the
best utilization of floor space, by vertically stacking
the prime mover, Synchrodrive, and the load device.
