Frequently Asked Questions
The self-locking property of a worm gearbox depends on the gear ratio and the lead angle of the worm. At high reduction ratios (generally from i = 30:1), our worm gearboxes are self-locking, meaning the output shaft cannot drive the input shaft into rotation. This is particularly advantageous in lifting and positioning applications, as no additional brake is required.
The efficiency of worm gearboxes typically ranges between 40% and 90%, depending on the gear ratio, lubrication, and operating conditions. Lower reduction ratios generally achieve higher efficiencies. Our high-performance worm gearboxes are designed for optimal efficiency and use high-quality materials to minimize friction losses.
Our range includes worm gearboxes with gear ratios from 5:1 to 100:1. This allows both moderate speed reductions and very high reductions to be achieved in a single gear stage. The maximum output torque is up to 4,368 Nm depending on the frame size.
Our worm gearboxes are factory-filled with high-quality lubricants and are prepared for continuous operation. Depending on the series, synthetic gear oils or special greases are used. The lubrication intervals and recommended lubricants are documented in the respective catalogs. For continuous operation under heavy load, we recommend regular oil level checks.
Worm gearboxes are characterized by particularly quiet and low-vibration operation, as the tooth engagement between the worm and worm wheel occurs by sliding contact. This makes them ideal for applications where noise is a critical factor, such as in building services, medical technology, or stage technology.
The standard operating temperature of our worm gearboxes is between -10°C and +40°C ambient temperature. Special versions with adapted lubrication and seals are available for extended temperature ranges. Under high continuous loads, the permissible gearbox temperature should be monitored to ensure optimum service life.
Yes, our worm gearboxes are available both as standalone gearboxes and in combination with electric motors. We offer fully assembled gear motors with three-phase, single-phase, or DC motors. Thanks to the wide range of frame sizes and gear ratios, a suitable motor-gearbox combination can be put together for virtually any drive task.
