Understanding Globoid Worm Gear: Features, Uses, and Maintenance

Globoid worm gear is an important gearing assembly that rotates against a wheel. The two shafts of the globoid worm gear are always at right angles. This gearing assembly is used in a variety of applications, including packaging machinery, elevators, and conveyors. It is a versatile solution for power transmission and can be used in both high-torque and low-speed applications. Let us take a closer look at this interesting product.

History of Globoid Worm Gear

The globoid worm gear was invented in the early 1900s by a German engineer named Wildhaber. The design improved upon the cylindrical worm drive, which had a limited load capacity. The globoid worm gear design used a special contour on the worm shaft and gear wheel to increase the contact area between the two components. This increased the gear's load capacity and efficiency.

Classification of Globoid Worm Gear

Globoid worm gear can be classified into two types: single-threaded and multi-threaded. The single-threaded globoid worm gear has a single helical thread on the worm shaft and on the gear wheel. The multi-threaded globoid worm gear has multiple threads on the worm shaft and gear wheel. The multi-threaded version has higher efficiency and better load capacity but is more expensive to manufacture.

Advantages of Globoid Worm Gear

The globoid worm gear design has several advantages over other types of gearing systems:

• Greater efficiency
• Higher load capacity
• Smooth and quiet operation
• Reduced wear and tear
• Longevity

Materials Used in Globoid Worm Gear

The globoid worm gear is typically made of steel, but other materials like bronze, aluminum, or plastic can also be used depending on the application. The worm wheel is usually made of bronze or cast iron. The gear material should be selected based on factors like load, speed, temperature, and humidity.

Installation, Maintenance, and Repair

Installation of the globoid worm gear requires proper alignment and lubrication. The gear should be installed on a flat, clean surface and the shafts should be aligned to ensure smooth operation. Lubrication is essential to reduce friction and wear. The gear should be inspected periodically for signs of wear and damage. Repairing the globoid worm gear can be complex and requires specialized knowledge and tools. In case of damage, it is recommended to consult a professional.
