Flange-Mounted Helical-Worm Gear Units with Hollow Shaft: Compact Power for Diverse Applications
Engineered for seamless integration and high performance, our Flange-Mounted Helical-Worm Gear Units with Hollow Shaft deliver superior efficiency and durability across industrial sectors. Designed for space-constrained environments, these units combine helical and worm gear technologies to provide smooth, low-noise operation with high torque capacity.
Key Features:
Hollow Shaft Design: Enables direct motor coupling or shaft-to-shaft connections, eliminating additional components and reducing installation time.
Flange Mounting: Simplifies setup with a compact footprint, ideal for machinery requiring precise alignment (e.g., conveyors, mixers, packaging equipment).
Dual Gear Technology: Helical gears ensure high efficiency, while worm gears offer high reduction ratios and self-locking capabilities for safety.
IP65 Protection: Dust and water-resistant housing for reliable operation in harsh conditions.
Customizable Ratios: Available in a wide range of reduction ratios (5:1 to 100:1) to meet specific speed and torque demands.
Applications:
Perfect for textile machinery, material handling systems, food processing equipment, and automation lines. The hollow shaft design is particularly advantageous for applications requiring quick tool changes or belt/pulley integration.

Q1: What are the installation advantages of the hollow shaft design?
A: The hollow shaft allows direct motor coupling or shaft-to-shaft connections without additional adapters, reducing setup time and costs. It also simplifies integration with belt drives, pulleys, or tools requiring quick changeovers.
Q2: Which industries benefit most from these gear units?
A: Ideal for material handling (conveyors, lifts), food processing (mixers, slicers), textile machinery (looms, spindles), and automation (robotic arms, packaging lines).
Q3: How efficient are helical-worm gears compared to standard reducers?
A: Helical gears offer 90-95% efficiency for high-speed applications, while worm gears provide self-locking functionality and high reduction ratios (up to 100:1). Combined, they balance efficiency and torque capacity.
Q4: Can the gear units withstand wet or dusty environments?
A: Yes! With IP65/IP67 ratings, they resist water jets and dust ingress. For corrosive settings, optional stainless steel coatings or aluminum housings are available.
Q5: Are there customization options?
A: Absolutely! Choose from:
Reduction ratios (5:1 to 100:1)
Input/output shaft orientations
Mounting flanges (F2, F3, etc.)
Lubrication types (grease or oil bath)
Q6: How often should maintenance be performed?
A: Lubrication checks every 6 months are recommended. Annual inspections ensure optimal performance, especially in high-temperature or heavy-duty applications.
Q7: What noise levels can I expect?
A: The helical gear design minimizes noise to ≤75 dB, making it suitable for noise-sensitive environments like food processing plants or workshops.
Q8: Do these units come with a warranty?
A: Yes! A 2-year warranty covers defects in materials and workmanship. Extended warranties are available for continuous-duty operations.
Q9: Can they handle shock loads?
A: Built with reinforced bearings and alloy steel gears, they tolerate short-term overloads up to 150% of rated torque.
