Dongguan Geyang Electromechanical Equipment Co., Ltd. is a professional sales agent specializing in silver Screw guides, including THK, FKS, NSK, NB, and TR.
In CNC machine tools, the feed drive mechanism consists of several key electromechanical components such as servo motors and detection devices, speed reduction systems, ball screw nut assemblies, screw bearings, and moving parts like the worktable, headstock, and column. This article will focus on the maintenance and care of the ball screw nut assembly, an essential part of ensuring smooth and precise movement.
(1) Adjusting Axial Clearance of the Ball Screw Nut
The ball screw nut pair must not only meet the accuracy requirements for unidirectional motion but also maintain minimal axial clearance to ensure accurate reverse transmission. Over time, wear can cause increased clearance, which needs to be adjusted regularly.
One common method involves using two nuts with a pre-adjusted gap set by the manufacturer based on user specifications. This design is simple, reliable, and widely used. For example, one nut has an external thread that allows adjustment via a Round Nut, followed by locking with another nut. This system is easy to adjust and can be fine-tuned during operation, though it doesn’t allow for precise control of the preload force.
Another method uses cylindrical gears on the flanges of the two nuts. These gears mesh with internal gears fixed on a sleeve. With different numbers of teeth (Z1 and Z2), rotating the nuts in the same direction relative to the sleeve allows for angular displacement when the internal gear is reinserted. This method ensures accurate preloading without manual adjustments.
(2) Daily Inspection of Sealing and Lubrication
Proper sealing and lubrication are crucial for the longevity of the ball screw nut assembly. Regular checks should be performed on the seal ring and protective cover to prevent dust and contaminants from entering. If grease is used, it should be applied periodically; if oil is used, make sure to consistently fill the oil through the designated oil hole. Maintaining proper lubrication helps reduce friction, prevents wear, and extends the life of the component.
At Dongguan Geyang Electromechanical Equipment Co., Ltd., we provide expert support and guidance on maintaining these critical components to ensure optimal performance and reliability in your CNC machines.
