Planetary Gearbox for AGV | AGV Drive Gearbox Selection Guide - Siemage

AGV (Automated Guided Vehicle) and AMR (Autonomous Mobile Robot) drive systems demand compact, precise and reliable transmission components. As a planetary gearbox manufacturer, Siemage supplies precision planetary reducers and hollow rotary platforms widely used in AGV drive wheels, steering units and lifting mechanisms. This guide explains how to select the right planetary gearbox for your AGV application.

Planetary gearbox for AGV: why gearbox quality matters

An AGV must start and stop smoothly, position repeatedly, carry rated loads and run continuously through a shift. The gearbox between the servo motor and the drive wheel directly determines positioning accuracy, motion smoothness and energy consumption. Compared with worm gear reducers, planetary gearboxes offer higher efficiency, lower backlash and a more compact size for the same torque, which makes them the preferred choice for servo-driven AGV systems.

Key parameters when selecting a planetary gearbox for AGV

Recommended series for AGV and AMR applications

• Precision planetary reducers SABL / SAD – for AGV drive wheels and steering axes where low backlash and high torque density are required.

• Precision planetary reducers SAB / SADL – for servo-driven positioning and indexing applications on automated guided vehicles.

• Hollow rotary platforms – for AGV steering units and rotary assemblies, combining bearing, housing and output in one compact unit.

• Custom planetary gearboxes – special ratios, input shafts, flanges, materials and protection levels developed according to your AGV chassis design.

Typical AGV drive configuration

A common AGV drive setup uses a servo motor coupled to a precision planetary gearbox driving the wheel hub. For AGVs with steering functionality, a hollow rotary platform is often used in the steering unit to provide smooth rotation and accurate angle control. Siemage supports this architecture with reducers designed for high overload capacity during acceleration, braking and obstacle handling.

Customization and integration support

Every AGV project has unique requirements in wheel diameter, travel speed, load capacity and working environment. Siemage provides customized planetary gearbox solutions covering special ratios, input interfaces, output flanges, sealing and protection levels. Our engineering team can review your torque, speed and space constraints and propose a matched transmission solution.

Frequently asked questions

Q: What ratio is typically used for AGV drive wheels?

A: For standard AGV drive systems with servo motors running at 2,000-3,000 rpm, ratios around 1:20 to 1:60 are commonly selected depending on wheel diameter and required travel speed. Siemage standard planetary gearboxes cover 3:1 to 200:1, so most AGV configurations are directly available.

Q: Can you provide a custom planetary gearbox for our AGV model?

A: Yes. We regularly design custom planetary gearboxes with special ratios, input shafts, flanges and materials according to the AGV chassis and drive layout. Send us your motor data, wheel size and load requirements for a proposal.

Q: How does backlash affect AGV positioning?

A: Backlash is the play between gear teeth. Lower backlash gives more consistent stopping position and repeatable navigation accuracy. Siemage single-stage reducers offer backlash down to 1 arcmin, suitable for high-precision AGV positioning.
