At China Gear Motions, we manufacture the most durable and high-quality precision ground helical gears in the industry. We supply compressor and supercharger companies around the world with this type of gear for mainly one reason…to reduce noise. The teeth on helical gears are cut at an angle to the face of the gear. This allows helical gears to operate much more smoothly and quietly than spur gears. Not only does this type of gear reduce noise, it is also stronger and lasts longer than spur gears.
When deciding which type of gear is best for your project there are a number of important measurements that should be considered. These include number of teeth, pitch diameter, outside diameter and center distance. The use of helical gears is generally needed when the application involves high speeds, large power transmission, or where noise reduction is important. This is why most car transmissions use them.
There are both single and double helical gears. Single helical gears consist of a single line of angled teeth around the perimeter of the gear. Double helical gears use two tracks of mirrored, angled teeth. These tracks are often separated by a gap for different machining objectives, but can be in direct contact with one another.
Helical gears can be produced by a number of precision gear manufacturing methods in a variety of materials. The methods used include shaping, milling, hobbing and casting. Materials used range from steel and cast iron to aluminum bronze. The materials used in gear design also play a large role in its performance and should be assessed based on the application. This is where temperature, speed and load all help determine requirements.
Our precision gear manufacturing facilities in Dongguan and Shenzhen Guangdong provide large volume and single or low quantity helical gears. Below you will find our capabilities for ground helical gears.
