The helical gears in this set have been skillfully machined using precision CNC machines. Through precise machining, the gears operate more effectively, with improvements in performance, reduced noise, and lower power consumption. These gears have been reinforced and feature an improved axle, while also boasting a lower gear ratio for faster operation - earning them the name "High Speed gears". The shellised construction of this kit decreases its weight, minimizing the load on the motor and reducing power consumption. Additionally, the motor itself is designed for high speed operation. In comparison to traditional gears with straight tooth profiles, helical gears offer several advantages such as quieter operation, smoother running due to increased contact points, higher durability and more precise motion control. These properties make helical gears a popular choice in mechanical and mechatronic systems.
