Hirata Helical is a type of helical gear that has been widely used in various industries, including automotive, aerospace, and industrial machinery. The helical gear is a type of gear that has teeth that are angled at a certain degree, typically between 10 to 45 degrees, relative to the axis of rotation. This design allows for smoother and quieter operation compared to traditional spur gears, as the teeth engage and disengage more gradually.
Design and Functionality
The Hirata Helical gear is designed with a specific helix angle that allows for optimal performance and efficiency. The gear teeth are cut at an angle, which enables them to engage and disengage smoothly, reducing vibration and noise. This design also allows for a higher load-carrying capacity and improved durability compared to spur gears. Additionally, the helical gear design enables the transmission of power at an angle, making it suitable for applications where the input and output shafts are not parallel.
