Articulated robots generally use rolling bearings in their joints to enable low-friction rotation and movement. Bearings are used to reduce the frictional resistance between the moving parts and increase the efficiency of the robot.
Different types of bearings are used in an articulated robot depending on the specific requirements of the application and the loads placed on the joints. Here are some common types of bearings used in articulated robots:
1. angular contact ball bearings: angular contact ball bearings are commonly used in the joints of articulated robots. They consist of inner and outer rings and a series of balls that absorb the load and enable low-friction rotation.
2. cylindrical roller bearings: Cylindrical roller bearings are used in articulated robots to absorb larger radial loads. They consist of inner and outer rings as well as cylindrical rollers that distribute the load and enable low-friction movement.
3. tapered roller bearings: Tapered roller bearings are used to support combined loads, both radial and axial loads. They consist of inner and outer rings and conical rollers that distribute the load and enable low-friction movement.
4. ball spherical plain bearings: Ball spherical plain bearings are used in the joints of articulated robots to allow movement in different directions. They consist of a ball joint that enables a pivoting connection and can simultaneously absorb the load.
Choosing the right bearing for an articulated robot depends on various factors, including the type of load, speed, accuracy requirements and the service life of the robot. Careful analysis of the application requirements is important to select the appropriate bearings and ensure optimal performance of the articulated robot.
Bearings play a crucial role in ensuring smooth and precise motion in articulated robots and contribute to the efficiency and reliability of these robots.
