High Reduction Right-Angle Gearboxes for Compact Drive Systems

Dunkermotoren introduced a new WG gearbox series that combines worm and planetary gearbox technologies in a compact right-angle configuration intended for industrial automation, robotics, medical devices, and mobile systems. The new drive solution targets applications requiring high reduction ratios, repeatable positioning accuracy, and high torque transmission within limited installation space.

Combination Design Extends Reduction Capability
The WG series integrates a worm gearbox with a planetary gearbox in a single assembly. This multi-stage configuration enables reduction ratios beyond the practical range of conventional single-stage right-angle gearboxes while maintaining relatively compact dimensions.

In many machine architectures, design constraints require a balance between installation space, torque output, positioning precision, and system cost. Single-stage bevel gearboxes typically provide compact right-angle power transmission but are limited in achievable reduction ratios. Spur gearboxes can offer cost advantages at lower ratios but are similarly constrained in reduction range. The WG design addresses this gap by combining multi-stage reduction capability with a compact right-angle layout.

According to Dunkermotoren, the resulting reduction-to-size ratio enables higher transmission reductions without a proportional increase in gearbox dimensions. This is particularly relevant for positioning systems, swivel axes, lifting mechanisms, and adjustment drives where compact mechanical integration is required.

Targeted for Automation and Medical Technology
The WG gearbox range was developed for applications operating under dynamic loads and restricted space conditions. Intended use cases include conveyor systems, robotics, automation equipment, medical handling systems, and autonomous mobile platforms.

The gearboxes support high acceleration and peak torque loads while maintaining repeatable positioning accuracy. Defined self-locking characteristics and low-noise operation also make the system suitable for sensitive medical environments such as operating tables, patient beds, and medical positioning equipment.

For battery-powered or mobile automation systems, compact dimensions and transmission efficiency are relevant factors in reducing overall energy consumption and system weight. Dunkermotoren states that the WG series is compatible with multiple motor platforms across its drive portfolio, supporting integration flexibility for OEMs developing compact motion-control systems.

Proven Gearbox Technologies Combined
Rather than introducing a completely new transmission architecture, Dunkermotoren based the WG series on existing worm and planetary gearbox technologies already used in standalone and combined drive systems. The approach reduces development and integration risk while supporting predictable multi-stage performance and long operating life under demanding duty cycles.

Benedict Hermann, Manager R&D Gearboxes at Dunkermotoren, stated that the company focused on combining established gearbox technologies to achieve a favorable balance between reduction capability, installation size, and overall system cost.

Three Sizes for Broad Integration
The WG combination gearbox series is available in three sizes: WG 52, WG 63, and WG 75. The product line is intended to support a broad range of industrial and medical motion-control applications where conventional right-angle gearbox concepts reach practical limits in reduction range or packaging efficiency.

By combining compact right-angle power transmission with multi-stage reduction, the WG series expands the available design options for OEMs developing high-torque, precision-oriented mechanical systems within constrained installation envelopes.
