Increasing the life of ball screw assemblies is crucial in keeping equipment functioning properly and avoiding downtime. While the life span of a ball screw assembly will vary depending on the conditions of which it is operating, there are several key ways that engineers can help improve the life of their ball screw assemblies, regardless of the application.
Reverse engineering allows for a replacement screw to be made for older or damaged components, even when drawings aren’t available. In addition to receiving the replacement part, new detailed drawings are also created in case a new screw is required in the future.
When determining which types of screws is best for a movement-centric application, an engineer has several options. Often, the decision must be made as to whether a lead screw assembly or a ball screw assembly will work best in the application. While these two types of screws will accomplish the same task, they each have key differences in the way they function and are maintained.
In complex assemblies, even miniscule movements can have an incredible impact on performance. This movement, called backlash, can be addressed in an assembly by using ball screws or ACME screws manufactured through the proper process. While screw type is often determined on a case-by-case basis, several broad factors should be considered when making that decision.
If a ball screw is malfunctioning, it can be frustrating. But is ball screw repair the right course of action, or should the ball screw be replaced?
