1. Types of reversible bearings: reversible bearings have small friction resistance, easy lubrication and maintenance, and are manufactured by technical professional chemical enterprises. However, compared with rolling bearings, the number of reversible bodies is relatively limited, the vibration resistance is slightly poor, and the rotational speed is limited. The larger limitation, the porcelain bearing means that the bearing reversing body is made of structural ceramics, and the reversing body is often used. The key is that it has the following characteristics: first, light weight, second, small linear expansion coefficient, and third, tensile strength. big.
2. Selection and preparation method of CNC machined bearings: the configuration method of two-support CNC machined bearings, including the selection of CNC machined models, the key basis is the speed ratio, bearing capacity, bending stiffness and precision of the CNC machined components involved. Provisions.
3. Incorporating the provisions of bending stiffness and bearing capacity: the maximum rotational speed ratios allowed by bearings of different types, specifications, and accuracy levels are different.
4. Incorporating the provisions of the speed ratio: Under the same circumstances, the premise of the selection of the CNC machined bearing configuration should consider the specified strength and bearing capacity, and the cylindrical roller bearing is higher than the tapered roller bearing.
5. The regulation of integration accuracy: the point contact is higher than the line contact, and the thrust bearing configuration of the CNC machining parts to bear the axial force also affects the radial part accuracy of the CNC machining.
6. Due to the overall design of some CNC lathes, the support span between the two supports in CNC machining is much higher than the better span. It should be considered to add a middle support to improve the strength and vibration resistance of CNC machined parts.
7. Strength and bearing capacity of CNC-machined overturned bearings: the bending stiffness and bearing types of fitness sports bearings, and the discrete system characteristics with the expansion of the load.
8. Lubrication of CNC machined bearings: Lubrication has a greater impact on the operating characteristics of CNC machined components and the service life of bearings, reducing the accuracy of CNC machining work. The lubricating fluid used to turn the bearing can be divided into two categories, namely plant Grease lubricants and liquid lubricants.
