Hypoid gears are a type of gear used to transmit power between shafts that are not parallel but intersect at an angle. They have a unique design where the pinion (small gear) is offset from the center of the gear, allowing for smoother operation and higher load capacity. This offset helps reduce friction and wear, making them suitable for heavy-duty applications. These gears are commonly found in automotive differentials and industrial machinery. Their ability to handle high torque and provide quiet operation makes them a popular choice in various mechanical systems. Overall, hypoid gears are essential for efficient power transmission in many engineering applications.
