Crown gears are a type of gear used to transmit power between shafts that are at right angles to each other. They have a conical shape and feature teeth that are cut at an angle, allowing for smooth engagement and efficient power transfer. Crown gears are commonly found in various mechanical systems, including automobiles and industrial machinery. These gears are often used in applications where space is limited, as they can effectively change the direction of motion without requiring additional components. Their design allows for high torque transmission, making them suitable for heavy-duty applications in fields like robotics and aerospace engineering.
