Expect Increased Efficiency with Hypoid Gearing Instead of Worm Gearing
Worm gears are the most common gear type. An alternative to a worm gear is the hypoid gear. Hypoid gears may look similar to worm gears at a glance, but due to the materials used for construction and the difference in how hypoid gears interact, they therefore transmit torque differently. Hypoid gears can show an overall cost and efficiency advantage. Two main factors in the cost of either type of gear set are material and manufacturing. Hypoid gear sets require a smaller footprint than a worm gear set to transmit the same amount of torque, thus giving hypoid gear sets a fit into tighter places. The result is more torque for less cost. A hypoid gear set can also have nearly twice the torque capacity of a similar sized worm gear reducer. With hypoid gear sets, efficiency remains constant with varying throughput speeds and across ranges of ratios compared to that of a worm gear set.
