Angular planetary gearbox, straight teeth, Ø 80 mm, reduction 5:1, 13 arc minutes, 67 N.m GBY080005K

Application and Key Features in Drive Systems

This straight-toothed angular planetary gearbox is a key component for precise motion control in industrial automation, particularly when paired with Lexium series servo drives. With a diameter of 80 mm, the unit is designed to effectively increase torque while reducing rotational speed, which is essential for handling heavier loads or demanding applications. Thanks to a gear ratio of 5:1, the motor can operate within its optimal speed range, while the output shaft delivers significantly higher torque – up to 67 N.m. This configuration enables stable transmission of high loads without risking motor overload, which is especially critical in continuous processes.

The precision of this reducer is ensured by parameters such as 13 arc.min (backlash), representing minimal tooth clearance. For the installer, this means easier calibration and reduced need for frequent position adjustments; for the end user, it translates into repeatable motion and high-quality operations, such as positioning of working heads or manipulator arms. The simple construction with straight teeth results in lower structural complexity and often reduced noise levels during operation compared to complex spiral gear systems, making it an excellent choice for machines operating in quiet environments or near operators.

Construction and Practical Installation

Mounting this accessory does not require specialized tools for complex assemblies, as its dimensions and connection method are standard for the Lexium product family. The reducer is classified as an "accessory," meaning it is not a replacement part for another device but rather an enhancement to the drive system, expanding its capabilities. Its compact housing with an 80 mm diameter allows integration even in space-constrained areas where every centimeter counts.

In practical operation, this gearbox stands out due to several key features affecting its durability and performance. It is designed to transmit torque up to 67 N.m, enabling safe operation under dynamic load changes without risk of mechanical damage. Simultaneously, the backlash of 13 arc.min ensures the precision required in applications demanding motion repeatability, eliminating unnecessary "play" of the output shaft. The product was developed as a dedicated solution for Lexium servo drives, eliminating compatibility issues related to mounting and electrical connections – the installer does not need to search for additional adapters or modify mounting arrangements. The use of straight teeth simplifies manufacturing and servicing while ensuring predictable friction and wear characteristics throughout the device's lifecycle, which is particularly valuable in machines operating intensively for many hours daily.

Selecting the appropriate model requires understanding the relationship between its dimensions and mechanical performance. In the case of this gearbox, its compact 80 mm diameter does not compromise the high output torque reaching 67 N.m, allowing installation in tight spaces without sacrificing drive power. At the same time, the 5:1 gear ratio and backlash of only 13 arc.min make the unit ideal for applications requiring precise position control while transmitting high rotational forces. Straight teeth further support this balance by offering quieter operation and reduced mechanical wear compared to more complex geometric solutions.

Operating Conditions and System Durability

This device is intended for industrial applications where reliability is paramount. As a mechanical accessory, it has no independent electrical power source – its sole function is to mechanically adapt the motor characteristics to the machine's requirements. Consequently, the reducer does not generate additional energy losses typical of electronic systems, but merely transmits mechanical energy with minimal friction losses within the gearbox.

It is worth noting that although this product is not covered by a take-back program (Take-back: No) from the manufacturer as part of a closed-loop lifecycle system for this specific model, its construction based on proven Schneider Electric solutions ensures long service life when properly installed and lubricated (if required). For installers, this means reduced
