Разуменне спіральных зубчастых перадач і іх пераваг

Helical cut gears are a distinct type of cylindrical gears with slanted tooth trace. Unlike spur gears, they offer a more substantial contact ratio, excel in quietness, and generate less vibration. This makes them capable of transmitting large amounts of force. The helical cut gears produced by WLY can be segregated into two groups according to the reference section of the gears, either in the rotating plane (transverse module) or normal plane (normal module).

Manufacturing Process of Helical Cut Gears

Producing helical gears involves using a spur gear hobbing machine and a hobbing tool. These gears can be created by tilting the hobbing tool when the reference portion of the gear is in the normal plane. However, this manufacturing process comes with a disadvantage as the twist of the teeth makes production more challenging.

Quality and Manufacturing Process

Regardless of the intricate process, WLY is fully capable of meeting your helical gear needs. Our manufacturing capabilities cover a wide range of sizes of custom helical gears with quality levels up to AGMA Q15. Whether you need metric, diametral, or other types of gears and splines, our team has the knowledge and experience to produce the high-quality gearing you need.


Helical Gears in Automotive Transmissions

Helical gears are often used in automotive transmissions as replacements for spur gears. They offer similar features and benefits to spur gears but are a more suitable option when higher velocities are required. In comparison to spur gears, helical gears have better tooth strength and a higher load carrying capacity. They also offer smoother and quieter operation due to their higher face contact ratio.

Advantages Over Spur Gears

Aside from smoother movement, higher speed capacity, and less noise, another advantage that helical gears offer over spur gears is their ability to be used with either parallel or nonparallel (crossed) shafts. This flexibility in design, combined with their high load and speed capabilities, often make them the preferred choice in applications that require non-parallel shafts or high speeds and loading.
