Helical Gear

As a well-known professional manufacturer and factory in China, Raydafon must be your trustworthy partner. We control the key processes in our own factories to ensure that every helical gear meets international standards from raw materials to finished products, and can control the price within a reasonable range to help customers obtain cost-effective transmission solutions.

Raydafon focuses on the in-depth research and development and manufacturing of helical gears. Its products are widely used in wind power speed increasers, automobile gearboxes, machine tool spindle drives, logistics conveyor lines and other industrial fields. Our helical gears are all processed by CNC hobbing, with tooth surface accuracy reaching ISO 6 level. The product design can bring greater overlap, effectively reduce operating noise and vibration, and improve transmission efficiency and load-bearing capacity. Whether it is heavy-duty equipment such as mining machinery or medical equipment with extremely high requirements for silence, we can provide matching high-performance gears for them.

Each helical gear is produced in Raydafon's own factory throughout the entire process - from 20CrMnTi carburizing steel cutting, CNC gear hobbing, carburizing and quenching, to gear grinding and finishing, and inspection before delivery. The entire process strictly implements the ISO 9001:2015 quality system. The gear measurement center can detect key indicators such as tooth guide error and helix angle deviation to ensure that the meshing noise of the finished product is ≤70dB, ensuring smooth transmission and durability.

At present, Raydafon's product has been widely used in wind power, electric vehicles, and high-end automation equipment, and its customers include well-known brands such as Goldwind Technology and BYD. For example, the large-module helical gear customized for a wind power company significantly reduces the operating vibration of the gearbox through the tooth top trimming design, and improves the operating stability and life of the whole machine.

Whether it is a helical gear with single-stage transmission and high-torque scenarios, or a multi-stage structure and high-precision positioning solution, Raydafon can provide you with professional selection suggestions and optimization support. If you need detailed data sheets, selection manuals or customized service quotations, please feel free to contact the Raydafon team. We promise to provide you with detailed technical and commercial support within 24 hours.

Can Helical Gears Be Used At Any Angle?

When many users first come into contact with helical gears, they often ask: "Can this type of gear be used for transmission at any angle?" The answer is not completely. Although helical gears have smoother and lower noise transmission characteristics, their working angles are limited and they are mainly suitable for power transmission between parallel and oblique axes.

In general, helical gears are most suitable for transmission between parallel axes because their helical gear structure can achieve a high degree of overlap, thereby reducing vibration, noise and increasing load capacity. In certain specific working conditions, helical gears can also be used for staggered axes (non-vertical cross axes), the so-called "oblique transmission", but this method will be accompanied by a certain degree of axial force and efficiency loss, which is not as stable as orthogonal transmission (such as bevel gears).

If you need a transmission structure with an angle of 90° or more, it is recommended to use bevel gears or spiral bevel gears, which are designed for vertical axes, with higher transmission efficiency and more reliable meshing.

In addition, helical gears are not the first choice for transmissions with atypical angles (such as 45° or 120°). Even if they can be achieved through special structural coordination, most engineers still prefer to use special gear types suitable for transmissions at this angle to ensure reasonable structure and reliable life.

Helical gears cannot be used for any angle. If there are special angle requirements, Raydafon's engineering team can provide a complete transmission solution including bevel gears, bevel shaft helical gears, etc., to help you choose the most suitable gear type to maximize the stability and efficiency of equipment operation.
