Helical Gear System

• Web Helical gears are cylindrical gears whose teeth are not parallel to the axis of rotation. The teeth are angled and appear as a segment of a helix. Helical gears can transmit power between parallel or right.
• Special teeth in helical gears are positioned at a specific angle to the shaft and the gear face. When two teeth in a helical gear system make contact, the initial point of touch is at one end of the tooth, and as the gears turn, the contact gradually expands until the two teeth are fully engaged.
• The helical gear rack has helical teeth cut into a surface of a square or circular cross-section rod, and its working principle is that the small cylindrical helical gear meshing.
