Abstract: 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.

Abstract: A linear transmission device with capability of wireless power supply includes a transmission mechanism and a wireless power supply module. The transmission mechanism includes a long shaft part and a moving part. The long shaft part defines an axis. The moving part is disposed on the long shaft part in a manner that the moving part is movable along the axis. The wireless power supply module includes a magnet-providing part disposed on the long shaft part for providing a magnetic field and an induction coil disposed on the moving part. A direction of the magnetic field is parallel to the axis. A normal vector of the induction coil is parallel to the direction of the magnetic field. When the moving part is moved along the axis, a current is induced in the induction coil through variation of the magnetic field.
