Including Bevel Gears Patents (Class 74/89.13)
  • Patent number: 10428930
    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 knurled press-fitting portion and an annular groove, which receives foreign matter and is formed to extend in a circumferential direction in front of the press-fitting portion of a cylindrical protruding portion, are provided at an outer peripheral surface of the protruding portion of an output shaft. A fitting portion, which is fitted to a coupling tube by press-fitting, is formed at an outer periphery of an opening end of the protruding portion. An outer peripheral surface of the cylindrical fitting portion and an inner peripheral surface of the cylindrical coupling tube coupled to a Z4 gear are fitted and coupled to each other. The annular groove is closed by the fitting portion in a state where the protruding portion and the coupling tube are coupled to each other. The annular groove is configured so as to prevent foreign matter from being discharged toward a bearing gear.
