drygear® Worm Gearboxes with Accessories – Precise Positioning Without a Motor
The drygear® RL-D worm gearboxes from igus are available in numerous sizes and configurations, offering maximum flexibility for a wide range of applications. One feature shared by all variants is the integrated central bore for routing cables or lines, enabling a particularly compact and tidy design.
All worm gearboxes can optionally be combined with perfectly matched motor kits and initiator kits. In addition, a comprehensive range of accessories is available, allowing the gearbox to be positioned comfortably and precisely by hand—ideal for adjustment, calibration, or positioning applications.
For manual adjustment, the drygear® worm gearbox can optionally be equipped with a handwheel. Depending on the application requirements, various versions are available:
- Handwheel with fixed handle
- Handwheel without handle
- Handwheel with safety handle
- Handwheel with foldable handle
The handwheel enables sensitive and controlled positioning of the output shaft, even at higher gear ratios. Especially during commissioning, maintenance work, or in applications with infrequent position changes, manual adjustment provides a simple and safe solution—completely without electrical power.
The gearbox can be complemented with additional functions to make manual operation even more convenient:
- Position indicator for a direct and easy-to-read display of the current position
- Hand clamp to securely lock the set position
This combination allows for reproducible adjustment and ensures that the position is reliably maintained even under external influences.
The worm wheel is made of tribologically optimized high-performance plastics and enables completely lubrication-free dry operation. The gearbox is therefore maintenance-free, clean, and particularly durable. All sizes are available for applications with increased axial as well as radial loads. In addition, the variants can be configured with a single-sided or double-sided output flange.
Thanks to their robust, corrosion-free design, drygear® RL-D worm gearboxes with accessories are ideally suited for industrial applications, test rigs, adjustment units, or machinery where precise manual positioning and maintenance-free operation are essential.
