ABB brand FSI3205-4 ball screws are often used in precision transmission fields such as robots. The following introduces its characteristics and applications:
Features
High precision: ABBA ball screws are usually produced continuously using Japanese-made mechanical equipment. In the processes of grinding, assembly, inspection, etc., the temperature and humidity of the factory environment are strictly controlled, and the perfect quality management system ensures its accuracy.
High efficiency: There are many balls between the screw shaft and the nut for rolling motion. Compared with the sliding screw pair, the driving torque can reach less than 1/3, and the same motion result can be achieved with less power, which performs well in power saving.
Precise micro-feed: Using ball motion, the starting torque is extremely small, and there will be no creeping phenomenon like sliding motion, which can ensure accurate micro-feeding and meet the requirements of robots for fine movements.
High rigidity: The axial clearance can be made negative by adding preload, thereby obtaining higher rigidity. The repulsive force of the ball can enhance the rigidity of the nut, can withstand large loads and frequent movements, and is suitable for the force requirements of the robot under different working conditions.
High-speed feeding: high movement efficiency, low heat generation, can achieve high-speed feeding, which helps to improve the working speed and production efficiency of the robot.
Size and load parameters
Screw shaft diameter: 32mm.
Lead: 5mm.
Ball diameter: 3.175mm.
Nut outer diameter: 46mm.
Nut length: 53mm.
Dynamic rated load: 1924kgf.
Static rated load: 3403kgf.
Application in robots
Achieve precise motion control: The robot's arms, joints and other parts require precise position control and motion accuracy. The FSI3205-4 ball screw converts the motor's rotational motion into precise linear motion, enabling the robot to accurately complete various actions, such as grasping, placing, welding, spraying and other operations, to ensure the accuracy and quality of the work.
Improve movement speed and efficiency: Its high-speed feeding characteristics can make the robot's moving parts move quickly, shorten the working cycle, and improve production efficiency. For example, in an automated production line, the robot can complete tasks such as material handling and parts assembly faster.
Load bearing: The robot may need to bear a certain load during work, such as grabbing heavy objects or being subjected to external forces during movement. FSI3205-4 ball screws have high rigidity and load-bearing capacity, which can reliably support the robot's moving parts and bear the corresponding load, ensuring the stability and reliability of the robot.
