Planetary gearbox, straight teeth, Ø 60 mm, reduction 5:1, 10 arc minutes, 40 N.m GBX060005K

Precision and Torque in a Compact Housing

This planetary gearbox from the GBX series has been designed as a key component of the Lexium drive system, combining high torsional stiffness with compact dimensions. With an outer diameter of 60 mm, the device fits perfectly into mounting spaces requiring space savings without compromising performance. Designed to work with stepper motors with a diameter of 55 mm (BSH series) and 70 mm (BMH series), it ensures a direct mechanical connection that minimizes backlash and increases the responsiveness of the entire motion control system.

The interior of the gearbox features simple gearing, which, combined with a black-anodized aluminum housing, enhances its durability and corrosion resistance. The output shaft made of C45 steel guarantees long-term operation even under heavy loads. A key design aspect is that the gearbox is lubricated for life – this means no maintenance or grease replacement is required throughout its service life, significantly simplifying service processes and reducing installation maintenance costs.

Application in Demanding Automation Applications

The device performs particularly well in applications where positioning precision and the ability to transmit high torque are critical. With a reduction ratio of 5:1 and a maximum continuous torque of 40 N.m, the gearbox effectively increases the torque available at the output, allowing heavier loads to be driven while maintaining optimal motor speed. Low backlash (maximum 10 arc minutes) ensures high position repeatability, which is critical in packaging machines, industrial robots, or internal transport systems.

High energy efficiency of 96% translates directly into lower energy losses and reduced heating of the system during continuous operation. The gearbox can be mounted in any position – vertical, horizontal, or inverted – giving installers great flexibility when designing the drive system. The operating temperature range from -25°C to +90°C allows the device to be used even in difficult environmental conditions, e.g., in production halls without air conditioning or in rooms with variable ambient temperatures.

Key Parameters and Operational Benefits

When choosing this model, it is worth analyzing its technical parameters in the context of specific application requirements: a reduction ratio of 5:1 is optimal for tasks requiring increased torque with a moderate speed drop. The maximum continuous torque of 40 N.m allows heavy loads to be transmitted without the risk of damage during continuous operation. Low backlash below 10 arc minutes guarantees high positioning precision and minimizes return error after a change in direction of motion. High torsional stiffness of 2.3 N.m/arcmin ensures resistance to deformation under load and better system reaction dynamics. The lightweight construction with a mass of approx. 0.9 kg facilitates mounting and reduces the inertia of the entire drive system, while the IP54 protection rating for the output shaft protects against dust and water splashes, ensuring safe operation in standard industrial conditions.

For installers, data regarding forces acting on the output shaft is also important: the maximum radial force is 340 N, and the axial force is 450 N (assuming an operating time of 30,000 hours). These values allow for the safe design of working mechanism mounts without the risk of excessive gearbox bearing wear. The moment of inertia of only 0.078 kg.cm² means the system reaches the required speed very quickly, which is crucial in work cycles requiring frequent starts and stops. The noise level does not exceed 58 dB (measured at a distance of 1 meter), making this model suitable also for applications operating near operators or in quiet production zones.
