Helical Gear Design

The gears in a helical reducer are cut at an angle to the face of the gear. Unlike straight-cut spur gears, helical gears have teeth that are set at an angle to the gear axis, providing a gradual engagement of the gears. This design allows for more tooth surface contact, which distributes the load more evenly.

Smooth and Quiet Operation

The gradual engagement of helical gears results in a smoother and quieter operation compared to spur gears. This makes helical reducers ideal for applications where noise reduction is important.

High Load Capacity

Due to the increased surface contact between teeth, helical gears can carry more load than spur gears of the same size. This makes helical reducers suitable for high-load applications.

Increased Efficiency

The efficiency of helical reducers is generally higher than that of spur gear reducers, particularly at higher speeds. This is due to the reduced friction and heat generated by the smoother operation of helical gears.


Helical reducers can be used in a variety of applications and industries, including automotive, industrial machinery, conveyors, and material handling systems.


The enhanced load distribution and reduced stress on individual teeth contribute to the longevity and durability of helical reducers.

Axial Thrust

One characteristic of helical gears is that they generate axial thrust, a force parallel to the axis of rotation. This requires helical reducers to have bearings that can accommodate these forces, adding to the design complexity.

Compact Design

Compared to other types of gear systems with similar power transmission capabilities, helical reducers often have a more compact footprint.

High precision low noise hypoid Reduction Gearbox reducer

KM series high-precision hypoid helical bevel gear reducers represent advanced solutions that the current market requires in terms of high efficiency and flexibility. It has the following characteristics:
1. 2-stage or 3-stage helical or hypoid bevel gear set, with a maximum reduction ratio of 7.5 to 300.
2. Hard tooth surface gears have higher gear hardness and strength than NMRV series worm gears. Durable and long lasting.
3. Super energy saving. The efficiency reaches more than 90%. Compared with the NMRV series worm gear reducer, the efficiency is increased by about 10% to 40%.
4. Modular design, diverse combinations
5. Installation dimensions are compatible with NMRV series (except size 050)
6. The high-efficiency KM series can replace the RV series and has a wider range of applications.

How Helical Reducer Work

A helical reducer, a type of gear reducer, operates using helical gears which are cut at an angle to the face of the gear. When these gears engage, they create a smoother, more gradual transfer of force than standard spur gears. As the helical teeth engage, the contact starts at one end of the tooth and gradually spreads across the entire tooth, resulting in less noise and vibration than spur gears. The helical design allows for more teeth to be in contact during operation, thereby increasing the load capacity and efficiency of the gear. In the reducer, the helical gears are used to decrease speed and increase torque, effectively transmitting power from a high-speed motor to a slower speed application, making them ideal for applications requiring high precision and smooth operation in industries like automotive, manufacturing, and machinery.
