    Abstract: A ball screw adapted to detecting coolant liquid includes a screw, a nut, a plurality of sealing members, a sensor, a signal processing unit and a cover. The nut includes a main body and an end surface, and a through-hole and a flow channel are disposed on the main body. The nut is threadedly disposed on the screw via the through-hole. A plurality of openings are disposed on the end surface, and the openings communicate with the flow channel. The sealing members are disposed in the plurality of openings. The sensor is disposed on one of the sealing members to detect a pressure of the coolant liquid and output an original signal. The signal processing unit is electrically connected to the sensor to receive the original signal and convert the original signal to a digital signal. The cover is disposed on the sensor and fixed to the nut.

    Abstract: A ball screw with a cooling passage includes a ball screw, a nut and a sealing unit. The nut is provided with the input and output cooling holes parallel to the axis, and the flat surface is provided with the guide groove. A first hole and a second hole are disposed between the guide groove and the input cooling hole and the output cooling hole, respectively, and then a sealing unit seals the guide groove, so as to form the cooling passage. The guide groove, the first hole and the second hole all extend along the axial direction of the nut, and the cooling passage can be formed simply by sealing the guide groove with the sealing unit, which effectively reduces the assembling steps and time, consequently decreasing the assembling cost.

    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.
