Abstract: A linear actuator and an identification method thereof are characterized in that a memory unit of the embedding device stores the parameter data of the linear actuator, such as the parameters and the axial position of the elongated shaft, and the microprocessor determines whether the sensing device is activated, and through the process of parameter analysis, data transmission, and algorithm calculation, the calculation control device performs an instantaneous calculation to determine the state of the linear actuator, thereby improving the disadvantage of a single function of the conventional technology, avoiding the problem that the unidentified linear actuator causes the abnormality of the sensing device, and effectively finding the problem of abnormal function of the linear actuator.

Abstract: A dustproof device is provided for use with a ball screw which includes a screw rod and a nut mounted around the screw rod. The dustproof device includes an annular body and an elastic valve plate. The annular body is disposed inside the nut and penetrated by the screw rod and has an outer annular surface provided with a debris exit. The debris exit has one end in communication with a spiral passage formed between the screw rod and the nut. The elastic valve plate, which is provided at the opposite end of the debris exit of the annular body, can be pushed open by a fluid and thus opens the debris exit, allowing the debris generated by the ball screw to be discharged through the debris exit along with the fluid, thereby contributing to extending the service life of the ball screw.

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 sensor assembly includes: a base with an installation space; an electrical connection member disposed on the base; a sensing unit including at least two physical sensors and one integrated circuit board; and a contact member disposed at one end of the base. The sensor assembly is a combination of the temperature sensor and the vibration sensor, the main physical parameters (including back clearance, collision, thermal displacement and lubrication) regarding the operation of the linear motion transmission device can be calculated based on the temperature signal and vibration signals, without requiring the installation of separate different sensors. Therefore, installation space is reduced. The sensor assembly is directly abutted against the linear motion transmission device to detect the change of various physical values in a most direct manner.
