CVT
A completely steel made chain variator works with a constant power
output while changing speed and torque: also recent developments
in automotive industry are based on PIV technology.
Variation of torque with constant power output, high efficency with
torque sensor, good level performances as a result of high tech
chains, independent speed control of driving and driven unit, drive
management with several driven units are the most important features
of CVT applications.
Technical Data
Power Rating: up to 150 kW
Speed range: R= 2,4 up to 6
POSIDISC variable speed gear
The spherical disc gear POSIDISC is the 'all-rounder' amongst the
infinitely variable speed gears from PIV: easy maintenance, favourable
behaviour in extreme operating conditions and the speed adjustement
both during operation and at standstill, make it very interesting.
The gear is completely insensitive to jolt operation. Even if the
output is blocked per short times, no damage occurs: a starting
or safety clutch is not needed. Operating factors need not be specified
for dimensioning, the gear can be run with its catalogue torque
in continuous operation.
Technical Data
Variation Ratio: 6 – 10 or up to output speed = 0
Power Rating: up to 3 kW
POSICHAIN Variable speed gear
The PIV POSICHAIN (A200 and RH series) gear is the 'classic' infinitely
variable speed gear from PIV.
The most important features are:
Simple maintenance and high efficiency that enables economical solutions,
even in continuous operation, and high speed setting accuracy.
The features of the 'torque converter' permit high torques at small
speeds. Extensive accessories such as regulating device, tachometer,
position response synchro, limit switch extensions and speed governor
are also avaible. High system protection for operation in dirty
environments.
Technical Data
Torque (T2max): up to 160.000 Nm
Speed range R= 2 – 3 – 4 and 6
Power Rating: up to 175 kW
POSIMAR Generator drive
The POSIMAR generator drive is the ideal adaptation between the
varying-speed motor (ship's engine, railway engine, generator motor
etc.) and the constantly-rotating power generator. An electro-hydraulic
control integrated in the gear adjusts the ratio so that the generator
speed is kept constant to 1%.
Technical Data
Variation Ratio: up to 6
Power Rating: up to 400 kW
