What is the common installation form of high-speed precision angular contact ball bearings in machine tool spindles-
High-speed precision angular contact ball bearings are especially suitable for bearing generated loads, that is, loads that act simultaneously in the axial and radial directions. Single row angular contact ball bearings are generally used by combining two or more bearings of the same type. When installing the application, there are three ways: back-to-back, zero distance, and sorting in the same direction. When high-speed precision angular contact ball bearings are used in machine tool spindle components, what kind of installation method is generally used? Today, the editor sorted out the relevant technical documents and recommended them to everyone. I look forward to being of some help to you! High-speed precision angular contact ball bearings are often used in machine tool spindle components as spindle bearing supports. A common configuration of angular contact ball bearings in machine tool spindle components. This type of structure is widely used in grinding machine tools. It uses a layout method in which two sets of bearings are arranged in the same direction and placed on both sides of the shaft. The outer ring lines of a pair of bearings at the right end are axially fixed, while the outer ring lines of a pair of bearings on the left are staggered to the left in the radial direction, and the right side is supported by a spring seat supported by a spring. In this way, when the temperature rise causes the spindle bearing to stretch, the left pair of bearings can also move to the left in the sleeve size, thus compensating for the thermal deformation of the machine tool spindle, so that the bearings still maintain the original preload. The springs in it clear the bearing play and increase the preload. The size of the pretightening force is determined by the working load, and thus the spring specification and the total number of springs are determined. Such a structure has been proved to be very scientific and reasonable by practical experience, and is suitable for places with high speed ratio requirements and light loads. Only when the torque is accurate can the rotation be stable! This article is from Co., Ltd., a manufacturer of high-speed precision angular contact ball bearings for 37 years.
