  • Patent number: 7416345
    Abstract: A retainer for holding bearings within a shaft bearing has C-shaped pockets for holding the bearings. Between the pockets are connecting portions, which are close to the openings of the pockets. The rear sides of adjacent pockets and the rear side of the connecting portion for the adjacent pockets form a concave site that is deeply gouged into the retainer. The bottom of the concave site is closer to the openings than the bottom of the pockets, thereby allowing base oil from grease in the concave site to better migrate onto the bearings and so lubricate the shaft bearing.

  • Patent number: 7366578
    Abstract: Typical numeric data for specifying a shape of a first product having a typical size are stored in a storage portion. By an input portion (10), a size of a second product other than the typical size is input. A calculating portion (4) determines recommended numeric data for specifying a shape of the second product based on the size of the second product and the typical numeric data. By the input portion (10), furthermore, corrected numeric data for the recommended numeric data are input. The calculating portion (4) decides the validity of the corrected numeric data. In the case in which the corrected numeric data have the validity, the calculating portion (4) determines final numeric data for specifying the shape of the second product based on the recommended numeric data and the corrected numeric data. Based on the final numeric data, the shape of the second product is drawn by CAD software.

  • Patent number: 7353150
    Abstract: First of all, size data (MD), (BD), (BH) and (MW) of a tire are input. Next, a ratio (b/a) of a major axis radius (b) to a minor axis radius (a) of an ellipse (18) is input. Then, constants (S), (a) and (b) of an involute function are calculated. Based on the involute function having these constants, a profile function (22) from a central position in a lateral direction to a maximum width position is determined over an X-Y plane. Subsequently, the profile curve (22) is divided into a large number of segments. Next, each of the segments is caused to approximate to a circular arc. In the approximation, a radius of curvature is determined in such a manner that the adjacent circular arcs are tangent to each other. Thus, a profile is designed.
