Ball screw bearing introduction
Ball screw bearing is a kind of bearing composed of a screw, nut, reversing device, and ball used to convert rotary motion into linear motion or convert linear motion into rotary motion.
The ball screw pair has the characteristics of high precision, reversibility, and high efficiency. This is a further extension and development of the trapezoidal screw. The important significance of this development is to turn the sliding action of the trapezoidal screw into a rolling action. Because of its low frictional resistance, ball screw bearings are widely used in various industrial equipment and precision instruments.
In order to adapt to various purposes, the ball screw pair provides a wide range of standardized products. The circulation methods of the balls include circulating duct type, circulator type, and end cap type. Preloading methods include positioning preloading (double nut method, position preloading method), and constant pressure preloading. The appropriate type can be selected according to the purpose. The screw has high-precision grinding precision ball screw (precision is divided into 7 grades from CO-C10) and cold-rolled ball screw bearing formed by high-precision cold rolling (precision is divided into 3 from C-C10 A level, only a few can do it). In addition, in order to cope with the urgent need for delivery by users, there are finished products that have been processed on the end of the shaft, semi-finished products, and cold rolled ball screw bearings that can be freely processed on the end of the shaft. As the peripheral parts of this bearing, the screw support unit, nut support, lock nut, etc. necessary for use have also been standardized and can be used by users.
The ball screw pair is based on the accumulated product technology over the years. From materials, thermal management, manufacturing, inspection to shipment, it is managed by a strict quality assurance system, so it has high reliability.
(1) Double push one freeway, one end of the screw is free. The fixed end bearing bears both axial force and radial force. This type of support is used for short lead screws with small strokes.
(2) Double push and one support mode, one end of the screw is fixed and the other end is supported. The fixed end bearing bears both the axial force and the radial force, and the support end bearing only bears the radial force, and can make a small amount of axial float to avoid or reduce the bending of the lead screw due to its own weight. At the same time, the thermal deformation of the lead screw can freely extend to one end.
