Precision Planetary Gear Boxes PTSC Properties The PTSC series of planetary gear boxes is designed in flange construction and with a backlash of ≤ 0,1 arcmin can be considered a zero backlash gear box. Due to a patented self-adjusting mechanism the precision stays constant over the entire and exceptional longlife endurance of 20.000h. A high efficiency, combined with a high tilting- and torsion stiffness as well as a low breakaway torque make this gear box unique in the market. PTSC planetary gear boxes are available in 7 sizes (additional sizes are under construction) with lifetime lubrication. They can be combined with our TAC-servo or TIS-stepper motors to rotary tables or other drive units. To optimize the installation space it is possible to add a bevel gear box on the input. For higher quantities and on request it is possible to get the PTSC gear boxes as sub-assembly without flange cover for direct integration into a structure. Advantages • Backlash ≤0,1arcmin for highest precision • Constant precision during the entire life endurance • Life endurance up to 20.000h, low cost of ownership • Efficiency >90%, energy efficient, drive with smaller motors possible • Low noise, low vibrations • Low heat development for longer lifetime of components and lubricants, suitable for S1 continuous operation • Low mass moments of inertia for dynamic operation • very good tilting- and torsion stiffness for straight-to-the-point positioning • Low break away torque for better controlling of the system • Lost Motion ≤0,6arcmin, precision also at low torques • Compact design, low weight • Hollow shaft version allows a feed-through of cables or tubes
