Harmonic Driver

TTRA Series
Properly applied to rotary table/position device, ATC,
tooling machine and each automatic mechanism
connected with servo motor directly.
The features of TTRA series are direct output, tightening engagement, and high accuracy.
TTRV-E Series
Developed for robotic industries.
The size of TTRV series is compact and light weight and
short dimension could eliminate the inertia of Robot swing
to achieve high precise positioning .
TTRV-C Series
Mechanism designers concern to array the cables or tubes properly due to the space limits or the interfering phenomenon between cable and structure during operation.
TTRV-C series could conquer this problem effectively due to it’s hollow design that allows tube & cable through the reducer-self.
TTRD-C Series
For meeting every demand in various industry, the input shaft of most robotic arm
and machines requires hollow-designed and connected with servo motor directly.
TTRD-C series is developed to solving the matter. The design of TTRD-C series
successfully carried out hollow-designed and directly connection with servo.
These features present more convenient and application-friendly .
TTRAC Series
Hollow body design,
allows the hydraulic tubes and electrical cables through
the reducer, belt input, proper to short
and limited space application.
TTGV / TTGH Series
Substituted for the two-stage planetary gear reducer.
Higher precision, lower cost, multi-teeth mesh,
highest rigidity, high torque, long service life,
extremely proper for high impact machine.
TTRAR Series
To meeting lots of requirements from customer side,
trunnion axis as short as possible,
which make the whole machine compact and space-saving.
TTRDR-C Series
To meet requirements from customer side,
are rotary table as low as possible,
which make the whole machine compact and space-saving .
