The structure of the screw nut seat is introduced, come and collect!

Friends who know about the screw nut seat should know that the main components of the screw nut seat are usually screws, nuts, balls, dust-proof sheets, etc. It can convert rotary motion into linear motion. Then in this process, as The main components of the screw nut seat, how do these components function to help the ball screw realize this process? In the following content, you will introduce the role of these parts of the screw nut seat one by one.

1. The function of the nut is to fix the load that needs to be moved. The principle is similar to the slider in the linear guide mechanism. Generally, it refers to connecting various loads to be moved (such as worktable and moving slider) with a nut, and then on the worktable or Various actuators are installed on the moving slider. Its internal processing is similar to the screw semi-circular raceway, and the design of the return pipe for the ball circulation, it is an important part of the ball screw mechanism, the performance of the ball screw mechanism depends largely on the nut.

2. Ball bearings, in the screw nut seat mechanism, the role of the ball is roughly the same as in the linear guide and linear bearings. As a part of the bearing body, it directly bears the load, and at the same time, as an intermediate transmission element, it transmits motion through rolling. Because it is a rolling motion, the friction generated during the motion is very small.

3. The dust-proof board is used to prevent external pollutants from entering the screw nut seat. As we all know, this product is a precision part. If dust, debris, metal slag and other pollutants enter the interior during use, it may cause serious wear and tear. Reduce the movement accuracy and service life of the mechanism, and even damage the screw or other parts.

4. The oil hole and the screw nut seat need to ensure proper lubrication during operation, so it is necessary to add lubricating oil or grease regularly. The function of the oil hole is to facilitate the supply of lubricating oil.

Screw nut seat is widely used in production, and its function is very powerful. We all know that screw nut seat is a precision part. Please pay special attention not to let sharp objects or tools touch the tooth surface when assembling the ball screw to avoid knocking or collision. At the same time, it should be noted that the screw cannot be separated from the screw. If it is separated from the screw, the steel ball will fall off. Once the steel ball is found to fall off, please do not put it back directly. Forced to put it back is easy to jam the screw. Do not knock hard during assembly. The pre-pressure of the angular contact bearing has been adjusted at the fixed end of the bracket. Do not disassemble it privately, otherwise the pre-pressure will be invalid and affect the overall accuracy. At the same time, ensure the parallelism of the component installation plane. Parallelism means that the allowable range of the linear guide ball screw up and down or left and right tilt error is 1/2000 (reference value). With a certain understanding of the role of the various components of the screw nut seat, when a failure occurs, we can promptly determine which part of the problem caused the failure, which is very helpful for daily maintenance! Hope the above can help you!
