Jinan Tianshan Jinggong Bearing Co., Ltd. introduced the structure of the ball screw pair. The structure is divided into an inner circulation structure (represented by a circular reverser and an elliptical reverser) and an outer circulation structure (represented by a cannula). These two structures are also the most commonly used structures. There is no essential difference between these two structural properties.
The shape of the inner loop structure inverter is various, but the commonly used shapes are circular and elliptical. Since the circular ball has a short reverse passage, it is not as smooth as an elliptical structure. Now, the best invertor structure is an elliptical inner channel structure. Since the ball reversal does not pass through the screw tip, similar to the outer loop structure, the screw tip chamfering error is eliminated to the reverse of the ball. influences. However, due to the complexity of the manufacturing process, the promotion of this structure has been affected.
Only the inner loop structure is installed with a small connection size; the outer loop structure is installed with a large connection size. At present, there are more than 10 types of ball screw pairs, but the more commonly used ones are: inner circulation structure; outer circulation structure; end cover structure; cover structure.
The ball screw pair is similar to the principle of the screw. Just add the ball. When the screw thread is rotated, the friction is more severe. After adding the ball between the internal thread and the external thread, it becomes rolling friction and improves the friction condition.

The boss, also known as the nozzle, is a disposable component of the automatic control instrument in the process piping, which is used to connect the supervisor and other components.
The single side double point welding of the convex platform has the following advantages: relatively low cost, multiple use of fixed equipment or robot welding; the surface deformation is slight, the quality is relatively stable; the welding efficiency is high, and the welding work of two welding can be completed at a time. The shortcoming is that there is a certain amount of grinding at the time.
