Globoid Worm Wheel · 模型 49357
A globoid worm wheel (also called hourglass worm gear) is a specialized type of worm gear where the worm has a concave (globoidal) shape that wraps partially around the worm wheel. Unlike cylindrical worm gears where the worm is straight, the globoid worm is curved to match the curvature of the gear, creating increased surface contact. Design Considerations Reduction Ratios: Typically, 5:1 to 300:1 Torque Capacity: Up to several thousand Nm in industrial applications Lubrication: Critical due to sliding contact; often requires specialized lubricants Materials: Worm typically hardened steel, wheel often bronze or polymer composites Globoid worm wheels represent an optimal solution when space constraints, high load capacity, and smooth motion transmission are critical requirements, justifying their higher cost and manufacturing complexity.
