Serie ZTRSPHQ

Our newly developed STOBER planetary gear units are especially impressive thanks to their outstanding precision and performance, as well as very low backlash, high torsional stiffness and exceptionally constant speed.

Quattro Power due to four-planet gear system. Bolted supporting bearing holder. Integrated pinion. Felt gear optional. Helical gearing. On request: Reduced play, right-angle input, direct motor attachment.

Supporting Bearing Holder

- Robust cast housing
- Optimized for stiffness due to internal ribs.
- The supporting bearing permits maximum feed force, minimizes the bending and increases the service life.
- Closed protected construction.

Output pinion

- Gearing quality 5
- Case hardened and ground
- Optional concentricity ≤ 10 µ

The choice of a pinion, which is as small as possible, reduces torque allowing the use of a smaller gear unit.

Mounting Positions

- Any mounting position.
- You can find the explanation of the mounting positions and the respective quantities of lubricant in the document Quantity of lubricant for gear units ID 441871

Lubricants and Maintenance

Gear unit:
- Synthetic lubricant CLP HC ISO VG 150
- Lubricated for life
- Maintenance-free

Rack and pinion drive:
- Optionally lubrication with felt gear
- Connectiion available for central lubrication or lubricator
- Lubrication of the rack and pinion drive must be carried out by the customer.
- For this purpose, we recommend only the use of high quality synthetic oil based grease of NLGI grade 0.

Paint Finish

Black RAL 9005

Motor Adapter ME/MEL

- Fast and easy motor attachment
- Single-part, rugged coupling with expanding function
- Lowest mass moments of inertia for highest dynamics
- Balanced for quiet, vibration-free operation, even at high speed
- Large range of motor shaft diameters
- Error-free thanks to exact centering of the motor
- For reduced backlash, the motor shaft bearing must have a design that is axially backlash-free

Motor Adapter MF/MFL

- Fast and easy motor attachment
- Rugged, laser-welded bellow coupling with expanding function
- With integrated thermal length compensation, compensates for linear expansion of the motor shaft
- Motor shaft decoupled from axial forces
- Balanced for quiet, vibration-free operation, even at high speeds
- Large range of motor shaft diameters
- Error-free thanks to exact centering of the motor

Option ServoStop

- Integrated in the motor adapter, electrically released spring-loaded brake.
- When the power is removed, in the event of a power failure or an emergency stop ServoStop will brake both drive and machine shaft safely and reliably.
- Zero-backlash plug-in coupling.
