  • Linear guideway capable of detecting abnormal circulation state
    Patent number: 10557504
    Abstract: A linear guideway includes a rail, a slider disposed on the rail, and a load passage formed between the rail and the slider. The slider has two non-load passages penetrating through two opposite end surfaces of the slider. Each of two ends of each non-load passage is provided with a force sensor. Two end caps are disposed on two opposite end surfaces of the slider respectively and each have two circulation grooves. Each circulation groove is connected to an end of the load passage and an end of the non-load passage to form a circulation channel for balls to move therein. As a result, the linear guideway of the present invention employs force sensors to sense the force-receiving state of two ends of the non-load passages when they are impacted by the balls, so that it can be determined that if the balls have an abnormal pressing state.

  • Noncontact fluid bearing and manufacturing method thereof
    Patent number: 10557501
    Abstract: A noncontact fluid bearing is manufactured by disposing a flow controller in a cavity of a carrier to form a pressure chamber within the cavity. A sealing layer of the flow controller is located between a porous layer of the flow controller and the pressure chamber and has micro through holes communicating with the pressure chamber and pores of the porous layer. Because the sealing layer is located in the pressure chamber and a surface of the porous layer is exposed by a housing of the carrier, the noncontact fluid bearing can be processed from the exposed surface of the porous layer to conform standards of thickness and flatness. Furthermore, the sealing layer peeling from the noncontact fluid bearing is prevented.
