In the load bearing capacity of the ball screw, both radial and axial loads exist simultaneously, and consideration should be given to the selection of bearings. Commonly used bearings that can withstand the load simultaneously include angular contact bearings and tapered roller bearings. The former focuses on dry light load and high-speed fields, while the latter focuses on heavy load and low-speed situations. It should be noted that the above two types of bearings are generally used in pairs and installed relative to each other (face to face or back to back), which can limit the axial movement of the screw rod.
Installation instructions for ball screw bearings: Using the installation sleeve, the diameter of the sleeve is the same as the inner ring of the bearing, and the material can be aluminum or copper sleeve to press the inner ring in. If the tolerance is tight or the interference fit is tight, the bearing should be heated. Pay attention to observing the contact angle of the arrow or the rolling element inside the bearing at its complete position. Generally, it is combined back to back or face to face, and finally screw on the locking nut. Retroreflector should be selected to check whether the installation position of the ball screw is consistent with the design request.
Features:
Ball screws boast a variety of impressive characteristics, such as high efficiency, low temperature rise, high precision, high speed, high rigidity, high reversibility, low maintenance, and a long service life.
These features are made possible due to strict testing and quality inspection processes, superior surface quality of the screw ball track, and strict control of the material and surface hardness. They are also enabled by excellent designs and impeccable manufacturing, making them capable of operating reliably at high speeds above 60M/min, and achieving high positioning accuracy due to the small temperature rise and measures such as pre tensioning and clearance elimination.
Moreover, the absence of viscous friction between the screw and nut eliminates the creeping phenomenon during transmission, while the nut end is designed with a special dust prevention device requiring only general maintenance during operation.
