lubrication
When using ball screws, sufficient lubrication is necessary. If the lubrication is not sufficient, it will come into contact with the metal, causing increased friction and wear, resulting in failure or shortened lifespan. The ball screw is an ideal product that converts rotary motion into linear motion, or converts linear motion into rotary motion. Ball screw is a commonly used transmission component in tool machinery and precision machinery. Its main function is to convert rotational motion into linear motion or torque into axial repetitive force, while also possessing the characteristics of high precision, reversibility, and A-rate.
resistance to compression
Like rolling bearings, the wear of ball screws can mix with foreign objects or moisture, sometimes causing damage. TBI ball spline is mainly composed of spline shaft, circulation sleeve, spline sleeve, and ball. Like ball screw, it is a type of transmission with high efficiency, reversible transmission, good synchronization, and high periodic accuracy.
Partial load
When the phenomenon of eccentric load occurs, it will directly affect the service life and noise of the screw, and most screws have poor operating feel. If the smoothness of the screw during unloading is different from that after assembly, in addition to paying attention to the accuracy of the screw itself, most combinations with poor accuracy will produce eccentric load phenomenon.
Smooth motion
Ball screws have higher efficiency than sliding screws and require less than 30% torque. TBI ball spline is mainly composed of spline shaft, circulation sleeve, spline sleeve, and ball. Like ball screw, it is a type of transmission with high efficiency, reversible transmission, good synchronization, and high periodic accuracy. It is easy to convert linear motion into rotational motion. Ball screws can maintain smooth motion characteristics even when preloaded. The support seat is a bearing that connects the screw rod and the motor. It is built specifically for the shaft end products of standard ball screw inventory. The standardization support units EK and EF are ready. Standard support units BK and BF have been prepared for ordinary ball screws. The fixed side support unit is equipped with pre loaded and adjusted JIS5 angular contact ball bearings.
Especially in the development of EK6, 8 micro, micro ball screw micro angular contact ball bearings equipped with a 45 degree contact angle, high stiffness, high precision, and stable rotational performance can be achieved. The support unit on the support uses deep groove ball bearings. The EK and BK inner bearings of the support unit are sealed with special gaskets and equipped with an appropriate amount of lithium soap grease, which can be directly installed and used for a long time.
Using A bearings
Considering the stiffness balance of the ball screw, a high stiffness, low torque (contact angle of 30 degrees, free combination) angular contact ball bearing is adopted. Meanwhile, EK6 and 8 are equipped with ultra small angular contact ball bearings for ultra small ball screws. This bearing has a contact angle of 45 degrees, a small ball diameter, and a small number of balls. It is a highly rigid and accurate ultra small angle contact ball bearing that can achieve stable rotational performance.
