Angular gearboxes Manufacturers online

Angular gearboxes are mechanical elements that transmit a rotary motion and torque between two axes that are not in a line but at an angle - usually 90 degrees - to each other.

Bevel gears or worm gears are often used for this purpose to enable space-saving power transmission in machines and drives.

Below you will find the functionality and types of angular gearboxes, an overview of their areas of application and their advantages:

How angular gearboxes work:

The main task of an angular gearbox is to transmit rotary movements and torques between two axes that are at a specific angle (usually 90°) to each other. The most important components of a bevel gearbox are:

1. The housing protects the internal components and ensures a stable bearing.
2. The gears are the main components for power transmission. They are often designed as bevel gears or worm gears.
3. Shafts are used to input and output the rotary motion.
4. Bearings & seals reduce friction and prevent the ingress of dirt.

Types of angular gearboxes:

There are various types of angular gearboxes, which differ according to their design and the types of gears used:

1. Bevel gearboxes use bevel gears to transmit power and are suitable for high speeds.
2. Worm gearboxes use a worm and a worm wheel. They are ideal for high reduction ratios and have self-locking properties.
3. The hypoid gearbox is a special form of bevel gearbox with offset axes for better torque transmission.
4. SpiroTec or spiral bevel gearboxes are suitable for more even power transmission with reduced wear.

Use of angular gearboxes:

Angular gearboxes are used in a variety of industries and applications:

1. Mechanical engineering & industry:
In conveyor technology for deflecting drives in conveyor belts and transportation systems.
In robotics as compact drive solutions for precise movements.
In printing machines for controlling and synchronizing printing units.

2. Automotive industry:
In the drive train, particularly in differentials for torque distribution.
In steering mechanisms.

3. Agricultural and construction machinery:
In tractors & combine harvesters to adjust the speed for various implements.
In excavators & wheel loaders as efficient power redirection for hydraulic systems.

4. Aerospace:
In aircraft mechanics for controlling flaps and landing gear.
In satellite technology as compact drives for alignment systems.

5. Medical technology:
In diagnostic devices as precise motion control for imaging procedures.
In prosthetics and rehabilitation devices for optimizing drive mechanisms.

Advantages of angular gearboxes:

• A compact design enables integration into space-critical applications.
• Efficient power transmission even with high loads.
• Adaptable to different operating conditions.
• Low maintenance requirements, especially for closed systems with lifetime-lubricated bearings.
• Modern designs such as spiral bevel gearboxes are highly efficient.

Angular gearboxes are essential components of many technical systems and offer an efficient way of changing the direction of rotary movements. Optimal performance can be achieved by choosing the right type of gearbox, high-quality materials and precise adaptation to the requirements.

Here are the most important aspects to look out for when buying angular gearboxes:

When purchasing angular gearboxes, there are numerous factors to consider to ensure an optimal selection for the application in question.

• Determine the technical specifications required for the application:
• The transmission ratio must meet the specific requirements of the application.
• Ensure that the gearbox can transmit the required torque.
• Observe the maximum permissible input and output speeds.
• Adapt the size and weight to the available installation space and the load requirements.
• Depending on the application, weigh up the advantages and disadvantages of bevel, worm or helical-angle gearboxes.
• Choose housings made of aluminum, steel or cast iron depending on the stability and weight requirements.
• Depending on your requirements, you can choose between lifetime-lubricated or serviceable models.
• Pay attention to the efficiency: Worm gearboxes have a lower efficiency than bevel gearboxes.
• If necessary, make sure that the gearbox is self-locking.
• In sensitive applications, look for low-vibration and low-noise models.
• Note the shaft designs: Solid shaft, hollow shaft or splines for direct mounting.
• Check whether additional coupling elements are required.
• Note the flange & mounting options. These must match the environment and the machine elements.
• Use in extreme temperatures requires special lubrication and materials.
• Stainless steel or coated gearboxes are suitable for harsh conditions.
• For shock & vibration loads, consider reinforced bearings and a robust design.
• If the gearbox is not maintenance-free, make sure that easy maintenance is possible.
• High-quality bearings and sealing systems extend the service life.
• Observe certifications and standards such as ISO 9001 for internal quality management. DIN EN 13463 as the standard for explosion protection in hydraulic applications or ATEX certification for potentially explosive atmospheres
• Compare the acquisition costs with the operating costs. Factor in efficiency, maintenance and service life.
• Good support and fast availability of spare parts are important.

The purchase of angular gearboxes requires a thorough analysis of the technical and economic factors to ensure an optimal solution for the respective application.
