摘要： A linear transmission device includes a screw, a moving member, a return element, and a sensor. The moving member is set in the screw to form a load path therebetween. The return element is set in the moving member and has a return path connected to the load path. The return path and the load path constitute a circulating path for balls to run. The moving member has an internal thread with an ineffective thread section. The moving member has a receiving groove adjacent to the ineffective thread section. The sensor is embedded in the receiving groove of the moving member without affecting the operation of the balls. Thus, the linear transmission device of the present invention can solve the problem of the sensor protruding from the moving member, so that the configuration of the surrounding space and the stroke of the moving member will not be affected.

摘要： 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.
