Abstract: A linear transmission device includes: an elongated shaft member, a moving module, a rolling unit, a return assembly, a sensor and a data receiving unit. The linear transmission device has a simple structure. The sensor is disposed at the junction of the first return pipe and the second return pipe of the return assembly to timely detect the change in the distance between the rolling elements, which can determine whether there is an abnormality in the shape of the spacers. With the sensor outputting detecting signals, it can stop the terminal immediately to confirm the condition of the workpieces and the machine, avoiding the structural damage of the machine and the workpiece caused by the continuous operation. The sensor can also serve as a medium for transferring data, further facilitating maintenance.

Abstract: A method is provided for evaluating a maintenance requirement of a linear transmission device that is driven by a driving device. A control unit receives, from a sensing unit, a plurality of electric sensor signals that respectively correspond to multiple physical quantities of the linear transmission device or the driving device. The control unit calculates at least four correction factors based on the electric sensor signals, and calculates a service life of the linear transmission device based on the electric sensor signals and the at least four correction factors for scheduling maintenance of the linear transmission device.
