The coupling is mainly the connection between the screw and the motor. It is one of the important parts in the linear module. The main purpose is to make the centerline of the two axes of the driving shaft and the driven shaft on the same straight line when the motor is working. This is related to whether the linear slide can operate normally and ensure accuracy, so the coupling is particularly important for linear modules that run at high speed.

The design of the linear module requires that the center of the two axes have an allowable deviation value, which is also required when the coupling is installed. From an assembly point of view, as long as the coupling can ensure that the coupling transmits torque safely and reliably, the center of the two axes The larger the allowable deviation value, the easier it is to meet the requirements during installation. However, from the perspective of the quality of the linear module, the smaller the deviation between the centerlines of the two axes, the more accurate the alignment, the better the operation of the linear slide, and the longer the life.

We fixed one end when the coupling is installed in the linear module. For example, after positioning of the host-side coupling, use this as a reference to adjust the other half coupling. The characteristics of the linear module make it align with the host-side half coupling. . Fix the dial indicator to the half coupling on the host side, and the contact of the dial indicator to the other half coupling, and turn this coupling to adjust it, and fix the dial indicator on the non-host side coupling. On the shaft, the dial indicator contacts the host side half of the coupling. It can be placed on the host side or the conveyor side with the meter, mainly for convenience. When centering, adjust the left and right values of the circle = up and down worth summing. In the end, the center of the alignment test is the coincidence of the centers of the two pairs of wheels, that is, the outer circles of the two pairs of wheels coincide.
