Two-stage slewing drive with extended center distance and high precision

In response to the customer’s specific requirements for a slewing drive used on automation equipment, U-TRSM has successfully developed a customized slewing drive solution through in-depth communication and technical efforts, which meets the demanding requirements of “extended center distance with maintained high precision.”

1. Key product improvements and advantages

Extended center distance solution: Based on the standard model 10411, an intermediate transmission gear has been innovatively added to effectively increase the center distance, while ensuring that precision and torque transmission capacity remain uncompromised. This perfectly meets the installation and operational requirements of the customer’s automation equipment.

High-performance parameters:

• Max speed: 70 rpm — suitable for medium to high speed operation scenarios
• Axial load: 751 kN, radial load: 281 kN — providing strong load-bearing capacity
• Standard torque: 3415 Nm, tilting moment: 58 kNm — ensuring stable performance under high-load conditions

2. Highlights of the two-stage transmission technology

As a key R&D focus of U-TRSM, this two‑stage transmission slewing drive offers multiple advantages:

• Significantly reduced gear meshing friction, lowering energy consumption and improving operational efficiency.
• Optimized layout, smaller size, and lighter weight, especially suitable for space‑constrained applications.
• Capable of withstanding high torque and impact loads, ensuring strong operational stability and extended service life.
• Low replacement cost for the pinion, helping to reduce equipment maintenance costs.

Through customized design and technological innovation, this product achieves an optimal balance of key parameters such as center distance, precision, torque, and energy consumption, providing a reliable transmission solution for the efficient and stable operation of automation equipment.
