Precision for machine tool drives The complete product range - Precision gear units - Ball screw motors - Rack and pinion drives

Gear engineering for machine tools Only the best for machine tools Precision metal-cutting machine tools become ever more productive and precise from machine generation to machine generation. Highspeed cutting and heavy-duty machines make very heavy demands on the drive axes. The gear units from STÖBER provide the right answer with new standards of drive engineering for these modern machine tool manufacturing requirements. Column boring mill Dynamic rapid traverse, continuous jerk free movements with instantaneous responses with variable loads are typical of the requirements for the metal...

Head start through innovation Gear ratios of up to i = 600:1 can be achieved with three-stage ServoFit® planetary gear units The practicality of STÖBER’s innovative developments is based on everyday proximity to machine tool customers. These high gear ratios or reductions enable the torque requirement to be obtained with smaller size motors. So designers of heavy metal-cutting machines can adjust the moment of inertia to perfection. This brochure for machine tool manufacturers combines tried and tested and new, innovative gear unit series, rack and pinion drives and ball screw drives to...

ServoFit® planetary gear units – for quality results Quality for high-end machine manufacture Helical planetary gear units with extremely robust housings ServoFit® planetary gear units are suitable for very high and maximum feed axis quality standards. The PH/PHA/PHQ/PHQA series differ mainly by their backlash and accelerating torque limits. Due to the extremely rigid construction and high STÖBER manufacturing quality level of the ServoFit® helical planetary gear units, they have earned a special place in machine tool manufacture. They stand out for their: The modular STÖBER system offers...

Uncompromised solutions from an extensive range ServoFit® PH(A) planetary gear unit Designed for high and very high machine tool manufacturing requirements such as reliability and torsional and tilting rigidity. Gear unit sizes: PH(A)3 – PH(A)10 Gear ratio: 4 – 100 Accelerating torque: 50 – 7,500 Nm Backlash PH: ″ 3 – 4 arcmin Backlash PHA: ″ 1 – 2 arcmin ServoFit® ServoFit® PHQ(A) planetary gear unit PH(Q)K right-angle Quattro system planetary gear unit ServoFit® PHKX right-angle planetary gear unit These gear units have four planets. This gives an increase in torque of up to 35% for the...

STÖBER rack and pinion drives – the new benchmark The new output bearing housing puts an end to oversized drives With the new output bearing housing and the new pinion/gear/flange interface configuration, all specification sizes have been significantly improved. The feed force was previously limited by the maximum permissible tilting moment of the gear unit bearings. The new output bearing housing lightens the load on the output bearings in the planetary gear unit. The lower tilting moment enables a smaller gear unit size to be used and a smaller motor to be fitted. The choice can now be...

From two specialists – for a perfect solution Supply as a complete gear unit/pinion/rack system Precision racks from ATLANTA STÖBER supplies the complete mechanical solution with motor adapter and coupling (type depends on gear unit) for connection to all common makes of servo motors for machine tool manufacture. With two rack classes (UHPR and UHP), STÖBER offers a complete ATLANTA rack range for very high specifications in machine tool manufacture. In addition to the helicaltoothed racks, straight-cut racks are also available. ME motor adapter with EasyAdapt® coupling ATLANTA precision...

Super compact ball screw motors from STÖBER For spindles of your choice High-efficiency motor engineering The universal, super compact STÖBER ball screw motors are designed for universal mounting to spindles from many different manufacturers. The super compact STÖBER ball screw motors offer an extremely high volume output. The basis is the industrial application of an orthocyclic tooth winding system. For individual solutions The STÖBER EZS and EZM ball screw motors in 2 sizes (5 and 7) and 3 lengths (power stages) offer a broadly based range for standard applications. This new system...

Also for direct drive of the spindle nut STÖBER EZM ball screw motor for spindle nuts with a flange to DIN 69051-5 A hollow shaft motor is needed for direct drive of a spindle nut. The STÖBER EZM servo ball screw motor with its generously sized flanged hollow shaft has been developed for these applications. Special axial angular contact ball bearings absorb the high axial forces from the ball screw drive. The design of the flange meets the requirements of DIN 69051-5, type S. As an alternative to the type S version, the flange nut can be mounted on the flanged shaft of the motor through...

ServoStop gear brake Simplifies assembly and servicing Cyclic brake test The holding torque of the brake system can be automatically tested when necessary (cyclic brake test). The brake lining is refreshed by several automatic “grinding” operations. Using the ServoStop gear brake, it is quite easy to remove or replace the motor on a vertical axis without any extra precautions. Fail-safe spring-loaded brake These brake management functions are carried out by the master control system. The holding brake integrated in a motor adapter is an electrically operated spring applied brake which is...

Quality from in-house production Quality is also a question of use of resources For reliable and durable use in metalcutting machine tools, planetary gear units must be highly rigid in design and flawless in manufacture. STÖBER is at the forefront worldwide for the manufacture of planetary gear units in this category. The reason for its leader position is mainly its in-depth experience over many decades in the manufacture of gear units with high-precision helical gearing. Example: ServoFit® PHQA planetary gear unit. Top gearing quality gives a backlash of < 1 – 1.5 arcmin Manufacture of the...
