Abstract: An automation apparatus includes a mechanism having a machine coordinate system and configured to work on a work which moves in the machine coordinate system, a sensor configured to successively detect positions of the work as the work moves, and a processor. The processor is configured to calculate a plurality of machine coordinate positions of the work in the machine coordinate system successively based on the positions successively detected by the sensor, and is configured to determine, based on the plurality of machine coordinate positions of the work, a working position at which the mechanism is configured to work on the work.

Abstract: An inner shaft provided in a vehicular bearing device includes a shaft-shaped body portion and a flange portion. The flange portion includes: a flange base portion that is continuous with the body portion and that has a circular cross section; a plurality of first thick portions each provided with a bolt hole, the first thick portions being provided radially outward of the flange base portion at equal intervals in a circumferential direction; and a thin portion that is provided between the first thick portions and that is thinner than the first thick portions. The flange base portion includes: a second thick portion that is positioned radially inward of the first thick portion and that is thicker than the first thick portion; and a small-diameter portion that is positioned radially inward of the thick portion and that has a smaller diameter than that of the second thick portion.

Abstract: A hub of a vehicle bearing device has a cylindrical portion and a flange portion. The flange portion has a pin hole formation portion, a reference position intermediate portion, separate position intermediate portions, and build-up portions. The reference position intermediate portion is formed between bolt hole formation portions. The first separate position intermediate portion is formed between bolt hole formation portions. The second separate position intermediate portion is formed between bolt hole formation portions. The pin hole formation portion is formed at the reference position intermediate portion, and has a hub side pin hole. A pin for fixing the hub and a brake rotor to each other is inserted into the hub side pin hole. The build-up portions are formed on the separate position intermediate portions, and are balanced in terms of weight with the pin-hole formation portion.

Abstract: A rotary ring of a hub unit has an annular first end face on one side in the axial direction, and an outer ring of a joint has an annular second end face on the other side in the axial direction. Outer splines are formed in a radially outer-side region of the first end face and outer splines are formed in a radially outer-side region of the second end face. The outer splines of the first end face and the outer splines of the second end face mesh with each other. Inner splines are formed in a radially inner-side region of the first end face and inner splines are formed in a radially inner-side region of the second end face. The inner splines of the first end face and the inner splines of the second end face mesh with each other.

Abstract: A rotary ring of a hub unit has an annular end face on one side in the axial direction, and a tapered outer periphery in a radially outer region of the end face. The diameter of the tapered outer periphery increases toward the other side in the axial direction. An outer ring of a joint has an annular end face on the other side in the axial direction, and had a tapered inner periphery in a radially outer region of the end face. The diameter of the tapered inner periphery increases toward the other side in the axial direction, and the tapered inner periphery faces the tapered outer periphery. Splines are formed in the tapered outer periphery and splines are formed in the tapered inner periphery, and the splines of the tapered outer periphery and the splines of the tapered inner periphery mesh with each other.

Abstract: Splines, which are to be meshed with a joint that transmits torque to a rotary ring of a hub unit, are formed in a side face of the rotary ring, the side face being on one side of the rotary ring in the axial direction. Spline grooves are formed in the side face by subjecting the side face to broaching.
