Raws li peb txhua tus paub, mechanical motion txawv ntawm tib neeg. Nyob rau hauv cov ntaub ntawv ntawm kev siv tshuab ua haujlwm siab, siab -ceev thiab ua haujlwm tau zoo yog qhov yooj yim kom ua tiav. Txawm li cas los xij, yog tias nws nyob hauv qis- nrawm nrawm, vim tias qhov ntsuas ntawm cov tshuaj tiv thaiv ntawm lub tshuab nws tus kheej thiab cov yam ntxwv ntawm cov khoom siv tshuab, nws yuav ua rau nkag mus rau qhov nrawm, thiab qhov no, yuav muaj ib qho phenomenon uas qhov precision tsis siab txaus. Lub pob ntsia hlau tseem yuav tsum muaj kev ruaj ntseg nyob rau hauv qis - nrawm nrawm kom ua tau raws li qhov xav tau ntawm ntau qhov chaw tsim khoom, yog li ob yam hauv qab no kuj yuav tsum tau them nyiaj rau:
1. Low-speed movement maintains stability
In the process of low-speed movement, it is very easy to crawl. In this case, the stability of the low-speed movement and the degree of lubrication between the guide rails must be considered. In proper low-speed movement, maintaining a certain friction force can make it easier to control the speed and effectively improve the accuracy.
2. The rigidity of the guide rail
Whether the guide rail will affect the accuracy under the external force, this must be considered. If the rigidity of the guide rail is not enough, it will directly affect the balance force, making it impossible to maintain linear motion efficiently. In order to make up for the rigidity of the guide rail, it is possible to appropriately consider increasing the size of the guide rail or other methods to increase the rigidity of the auxiliary guide rail.
The stability of the ball screw in the low-speed process is actually a way to ensure its accuracy. In the low-speed process, it is necessary to ensure that the rigidity of the guide rail can adapt to that environmental demand. In addition, during low-speed movement, proper consideration of the amount of lubricant used can effectively assist in increasing the accuracy and accuracy, so that the entire low-speed process will not affect the precision of the product.
