Bevel Helical Gearbox – Powerful and Efficient Angular Transmission
The bevel helical gearbox is a highly efficient and reliable solution for transmitting torque and motion at an angle. By combining the advantages of bevel gears and helical gearing, this gearbox offers smooth, quiet, and highly durable performance for demanding industrial environments. In this article, you’ll learn all about its structure, operating principle, application fields, and why it is worth choosing a bevel helical gearbox from Rehfuss Drive Solutions.
What is a bevel helical gearbox?
A bevel helical gearbox is a mechanical drive that transmits power between non-parallel shafts – typically at a 90-degree angle. It combines a bevel gear stage for directional change with one or more helical gear stages for torque multiplication and smooth operation. This makes it ideal for space-saving applications where power needs to be redirected while maintaining efficiency.
Key features:
- ✔️ Angular power transmission (usually 90°)
- ✔️ High torque density in compact housing
- ✔️ Low noise and vibration thanks to helical gears
- ✔️ Modular design with multiple gear stages
- ✔️ Robust performance in continuous operation
Structure and Function
The gearbox housing contains a bevel gear pair and one or more downstream helical gear stages. The bevel gears allow a change in direction of the power flow, while the helical gears provide the required speed reduction and torque increase.
Main components:
- ➡️ Bevel gear set for angle transmission
- ➡️ Helical gears for smooth and efficient torque transfer
- ➡️ Bearings and shafts for radial and axial load support
- ➡️ Sealed housing with lubrication system
Advantages of bevel helical gearboxes
✔️ High efficiency
Helical gears ensure minimal friction and high efficiency – often exceeding 95%, making the system energy-saving.
✔️ Space-saving angular drive
Perfect for compact machines where space is limited and directional change is required.
✔️ Low noise and vibration
Thanks to the helical tooth profile, operation is smooth and quiet – ideal for noise-sensitive environments.
✔️ Long service life
High-quality materials, precise machining, and optimized gear geometry ensure maximum durability even under heavy loads.
✔️ Versatile mounting options
Foot-mounted, flange-mounted, or shaft-mounted – bevel helical gearboxes offer flexibility in any installation.
Applications
Conveyor systems
They efficiently transmit power in systems with changing motion directions – for example, right-angle belt conveyors.
Packaging and processing machinery
Used in applications requiring synchronized movement and high positional accuracy.
Automated production systems
Thanks to their compact design and high output torque, bevel helical gearboxes are ideal for robotics and automation.
Steel and material handling
Heavy-duty variants are used in cranes, hoists, and rollers, delivering maximum power even in harsh environments.
Environmental and water treatment technology
With corrosion-resistant designs, bevel helical gearboxes are used in agitators, aerators, and sludge scrapers.
