(Newswire.net — June 24, 2021) — Do your linear guides start functioning at high friction spots or abruptly increase their speed? Or is it possible that the linear guide you’ve chosen isn’t raising the load correctly? Linear guides are mechanical assemblies that function as part of a more extensive system. As a result, their performance is limited by how well they are integrated into the giant machine. It is not sufficient to specify the proper guide. A comprehensive grasp of defining, designing, installing, and testing the linear guide is required to build a system that works as intended. Continue reading to learn about the most common mistakes people make when using and selecting linear guides.
1 Adding Alignment Mounting Features
The fitting of accurate linear motion guides necessitates precise alignment to achieve the highest level of performance. As a result, when selecting a linear direction, make sure it has the appropriate mounting features. Having this kind of functionality can help you work faster and more efficiently. The primary track can be straightened with a simple pair of alignment pins.
However, the tool needs more precise handling to achieve a high level of accuracy. As a result, ensure that the guides are installed using shoulder surfaces, which will aid in the delivery of successful outcomes. For the tracks and bearings, these surfaces provide a flat and stable support framework. As a result, a linear guide can achieve micron-scale straightness. Don’t forget to figure out which tracks have mistakes. If there is a considerable inaccuracy, it suggests the shoulder surfaces aren’t dimensioned appropriately.
2 Preload Isn’t Adequately Defined
Purchasing a precision linear guide with preload increases efficiency while lowering negative variables like vibration, noise, heat generation, and deflection. Linear guide rails, such as Drawer rails (Schubladenschienen) can suffer from insufficiently defined preloads, which can significantly increase friction and degrade system performance.
It’s only conceivable if the mounting surface’s precision matches the linear motion guides’ precision. The preload in the direction, on the other hand, can pose problems if the accuracy of both the mounting surface and the guides isn’t the same. As a result, the preload of the guides must correspond to the precision. If the accuracy isn’t up to par, a linear guide with a line-to-line fit (standard preload) or even a little extra clearance is recommended.
3 Mounting Surfaces Not Fabricated to Tolerance
Linear guides are precision-ground at the manufacturer to ensure that they operate with the least amount of friction. In an ideal world, regardless of whether a linear guide block is mounted or not, the friction of each linear guide block would be the same. In practice, any misalignment or unevenness of the mounting surfaces causes preload to be added to the linear guide system. The flatness of the mounting surface to which the rails are mounted and the parallelism of the linear guides to one another are both covered by mounting tolerances. The mounting tolerances or rail alignment are most likely out of spec if the friction in a guide increases when the component is fitted or is more intense at one end of travel than the other.
You can grasp the many design parameters and requirements when picking a linear guide such as Drawer rails (Schubladenschienen). After taking into account the relevant points. You may configure, source, and acquire a tool that will not only deliver precise results but will also increase performance if you conduct a thorough study.
