Roller Screw versus Ball Screw Actuators
In the ever-evolving field of engineering, roller screw technology has become a significant force in linear electric actuator motion control....
Axial planetary gearboxes with flange output shaft and with helical gearing. For servo drives with high specifications set for reliability, torsional and tilting rigidity.
7 sizes (PH3 to PH10).
Accelerating torques of 50 to 7,500 Nm.
Gear ratios from i = 5 to 100 (up to PH9=8) or from i = 9 to 10 (PH9 and PH10).
Backlash smaller than 3 arcmin.
Optional ServoStop: with a in the motor adapter integrated fail-safe brake.
The planetary gearbox can be supplied with a motor adapter and backlash-free EasyAdapt® coupling, suitable for every type servo motor. This coupling compensates thermal expansion of the motor. In addition, the gearboxes can be executed with a drive shaft.
The Power Line planetary gearbox is characterized by the output shaft executed as flange (according to IAO 9409) (PH3-PH8). Through the helical gearing and construction, the gearbox has high torsional and tilting rigidity, high accuracy and runs extremely quiet.
Two gantry robots for a repacking line with a working range of 2200 x 2030 x 1900 mm in the X-Y-Z plane where crates are stacked. The capacity of the stackers is calculated on crates of 10 kg and 6 cycles/min. There is also a product transfer unit in the repacking line with a working area of 1700 x 600 mm for handling rejected products.
The basis of the systems are the robust HSB portal axles from the Gamma series with double recirculating ball guides and toothed belt transmission. Due to the limited installation height, telescopic axes for the Z-movement have been used here. The linear modules are equipped with our Stöber planetary gearboxes, flexible for mounting any type/brand of servo motor.
The Stober ServoFit® gearboxes are available with a flexible system adapter and couplings for many servomotor
Assembly of the servo motor is simple. If desired, this can be carried out at the workshop of ATB Automation.
We supply slewing ring bearings, oscillating mountings, tensioner devices from stock and we also have spiral bevel gearboxes, servo gears and electromechanical actuators in our delivery program.
In addition we also select and offer the right components and systems for motion control solutions, such as servo gear motors, linear servo actuators and complete XYZ cartesian systems.
