Product Overview
The AT-H Series right angle servo gearbox is a high-strength right-angle gear reducer designed for modern automation equipment that requires precise positioning, compact size, and stable torque delivery. Equipped with a hollow output shaft, the AT-H Series offers flexible installation, excellent concentricity, and strong torque transmission—ideal for servo motor applications where space constraints and alignment flexibility are critical.
This AT-H Series right angle servo gearbox is built using high-precision spiral bevel gears, manufactured from SCM415 nickel-chromium alloy steel and hardened to HRC60 for exceptional durability. The gear geometry follows internationally recognized standards from organizations such as the American Gear Manufacturers Association (AGMA), which sets engineering benchmarks for power transmission systems.
By combining a spiral bevel gear stage with a high-efficiency planetary mechanism, the AT-H Series right angle servo gearbox achieves smooth operation, low noise, and efficiency ≥ 98%. The robust dual taper roller bearing structure gives the gearbox superior rigidity and enables it to handle high radial and axial loads—even under dynamic load changes.
To support design engineers in their selection process, reference materials from trusted engineering sources such as the Engineering Toolbox and Machine Design’s technical gear resources help illustrate the principles behind torque, inertia, and gear performance. The AT-H Series right angle servo gearbox is engineered following these established mechanical design fundamentals, ensuring compatibility with demanding automation applications.
Additionally, the importance of precision gear engineering has been widely documented by research institutions, including the NASA Mechanical Drive Systems Branch, which has published high-level studies on gear materials, lubrication, and load capacity. This reinforces how proper gear geometry and metallurgy—both used in the AT-H Series—are critical to high-performance servo gear reducers.
With frame sizes ranging from 55 mm to 220 mm, torque outputs from 15 Nm to 1600 Nm, and gear ratios from 3:1 to 100:1, the AT-H Series right-angle servo gearbox is versatile enough to support a broad range of servo motor capacities from 50W up to 15kW.
This makes it a reliable right-angle solution for industries requiring high precision, compact mechanical design, and long-term durability—such as robotics, CNC machinery, packaging automation, semiconductor manufacturing, and industrial logistics.
