High-Quality Rotary Joints at TORWEGGE
Rotary joints are large-scale roller bearings designed to simultaneously transmit axial and radial forces, as well as the resulting tilting moments. Due to their high load-bearing capacity, they are ideal for applications under heavy loads, such as in rail vehicles, excavators, cranes, aerospace, wind turbines, and much more.
In the TORWEGGE online shop, you will find steel rotary joints with internal or external gears for various applications in different designs. Our models are lightweight versions from the large-scale roller bearing program.
What Are Rotary Joints and How to Choose the Right Model?
Rotary joints are ball or cylindrical roller bearings consisting of an inner ring and an outer ring, with one of the two rings typically having teeth. They allow for the transmission of axial and radial forces, as well as tilting moments, between two adjacent machine components. The bearing tracks are designed in conjunction with the rolling bodies to safely absorb single or combined loads in all directions. Rotary joints are typically mounted horizontally, but they can also be installed vertically. When mounted hanging, the limit load curves do not apply, and an increased number of screws is required.
When selecting the right rotary joint, the first thing to consider is the load the joint will be subjected to, as well as the load groups with their corresponding time percentages. You should also take into account the rotational speed, the number of swiveling movements, and the swiveling angle per time unit with the associated load group. Furthermore, the tangential forces to be transmitted by the teeth and the bearing diameter also play a role in the selection.
How Rotary Joints Work and Types of Rotary Joints
The operation of a rotary joint relies on the use of bearings to enable low-friction movement. When the moving element (the inner ring) is rotated, the bearings glide over the bearing surfaces in the housing. This generates a low-friction rotation of the inner ring relative to the stationary outer ring. Seals can also be used to protect the bearings from contamination and to retain lubricants inside.
The specific operation can vary depending on the type of rotary joint, but the basic principle of low-friction rotation around one or more axes remains the same.
There are various types of rotary joints. Single-axis rotary joints allow rotation around a single axis and are often used in applications such as swiveling arms or steering mechanisms. Multi-axis rotary joints, on the other hand, allow rotation around multiple axes simultaneously. They offer greater freedom of movement and are used in complex applications such as robotics or camera systems. Additionally, there are rotary joints that transmit electrical signals or energy while rotating, often used in applications like wind turbines or industrial machines.
Our Range of High-Quality Rotary Joints
In the TORWEGGE online shop, you will find steel rotary joints of the L360 AZ and L360 IZ types, offering high load capacity. These ball rotary joints provide full 360° rotation and are available in various sizes with an outer diameter ranging from 505 mm to 1,198 mm. Additionally, models with internal or external gearing are available. The bearing cross-sections of this series are kept relatively small for economic reasons. Therefore, the large-scale roller bearings should be mounted on a torsionally stiff connection structure.
