Helical bevel gear units are a special type of spur gear unit and are used in many industries. They are characterized by their high performance, precision and reliability and are used in machines and systems in which force has to be transmitted and torques converted.
The special feature of helical-bevel gear units is their design: They consist of two intersecting and helical bevel gears. In the process, the rotary movements are maintained and simultaneously redirected in another direction. The helical teeth allow the wheels to mesh, ensuring efficient power transmission. The helical gearing also enables low-noise operation, as tooth meshing is smoother and more even.
The advantages of helical-bevel gear units lie primarily in their high load capacity and flexibility. They can transmit both high torques and high speeds. This makes them suitable for a wide range of applications, such as in the automotive industry, in aerospace technology or in the food industry. Bevel helical gears are also used in marine propulsion systems to transmit the power of the engines to the propellers.
Another advantage of helical-bevel gear units is their compact design. Due to the angled teeth and the crossing arrangement of the bevel gears, the gearboxes can be installed in a space-saving manner, which is particularly advantageous in tight installation spaces. In addition, the design enables high efficiency, as the tooth meshing is optimally designed and losses are minimized.
The assembly and maintenance of helical-bevel gear units is comparatively simple. They can be installed both horizontally and vertically and are usually equipped with oil lubrication to ensure a long service life. If required, the gear units can also be provided with additional cooling to prevent overheating.
Overall, helical-bevel gear units offer a reliable and efficient solution for power transmission in various applications. Their high load capacity, flexibility and compact design make them a popular choice among designers and engineers. Through continuous development and improvement of materials and manufacturing processes, helical-bevel gear units will continue to play an important role in the industry in the future.

What is a helical bevel gearbox and how does it work?
A helical bevel gearbox is a type of gearbox used to transmit torque and speed between two shafts that are at an angle to each other. It consists of a bevel gear and a spur gear, both of which are conical gears.
The bevel gear is located on the drive shaft and has conical teeth that taper outwards. The spur gear is located on the output shaft and has straight teeth. The two gears mesh with each other, transmitting the torque and speed from the input shaft to the output shaft.
The function of a helical bevel gearbox is similar to that of a worm gearbox. When the bevel gear is driven, it turns the spur gear on the output shaft. The angle between the shafts enables efficient transmission of torque and speed, even if the shafts are not parallel to each other.
Helical bevel gearboxes are often used in industrial machinery, vehicles and other applications where torque and speed transmission between two shafts at an angle is required. They offer high efficiency, reliability and durability.
