Linear module as a high-precision transmission component, once the problem of repeated positioning accuracy decline, it will directly affect the use of the module, when the use of the module in the process of finding a decline in positioning accuracy, generally consider the following aspects of the reasons.

First of all, it is necessary to check whether the parameters of the module and the motor can meet the load requirements, in particular, it is necessary to check whether the load eccentricity moment and the moment of inertia are within the load bearing range, if the strength can meet the requirements, then consider the problems existing in the module itself.

Secondly, the ball screw is the most important part of the module, and its accuracy directly determines the overall accuracy of the module. After long-term use of the lead screw, there will be certain wear, resulting in an increase in the back backlash of the lead screw, resulting in repeated positioning accuracy of the module. If you want the service life and accuracy of the module to be reliably guaranteed, it is recommended to give priority to the selection of imported brands or high-quality domestic screw, and pay attention to maintenance in daily use, regular cleaning and filling lubrication grease, which can greatly improve the service life of the screw.

In addition, if there is a collision during the use of the module stroke, it may lead to the bending of the lead screw or the loosening of the lead screw nut, and it will also lead to the reduction of the repeated positioning accuracy of the module. In this case, the use should be stopped immediately and contact the manufacturer, and the manufacturer can continue to use it after maintenance.

The above is the analysis of the common reasons for the decline of the repeated positioning accuracy of the linear module, and I hope to help you.
