    • A tapered roller bearing is proposed which can be assembled without the need of bottom expanding and caulking of its retainer. The diameter of the roller inscribed circle (R1) of tapered rollers (3) fitted in pockets (11) of the retainer is determined such that the roller inscribed circle (R1) has a portion that radially outwardly protrudes from the radially outer surface (R2) of a small flange (6) of the inner race (1) when the tapered rollers are at the radially outermost positions in the respective pockets (11) with an outer race (2) not mounted, and when the roller inscribed circle (R1) is offset from the center of a raceway circle (R3) of the end of a raceway (1a) of the inner race (1) at the small flange (6) so as to contact the raceway circle (R3) at one point. The portion (C′BC) of the roller inscribed circle which does not radially outwardly protrude from the radially outer surface (R2) of the small flange (6) has a central angle larger than 180° and not larger than 240°. The small flange (6) of the inner race (1) has such a thickness (t) that when the roller inscribed circle (R1) is offset from the center of the raceway circle so as to contact the raceway circle (R3) at one point (B), and swung about the one point (B) toward the small flange (6), the small flange (6) does not interfere with the arcuate locus (S) of the swing end of the roller inscribed circle (R1).

    • When a vehicle passes through an entrance IC entering a toll road, a present position of the vehicle changes discontinuously because of increased detection error. Continuity is lost between a designated travel road and a history of past designated travel roads. Designation of a correct entrance IC fails. Even in such a case, the correct entrance IC is designated based on the travel road designated before the continuity is lost. A toll is calculated based on the designated entrance IC and an IC, which the vehicle approaches and via which the vehicle is assumed to exit the toll road. If a guide route is designated when passing through an entrance IC, a correct entrance IC is appropriately designated from the travel road and the guide route.
    • 当车辆通过进入收费公路的入口IC时,由于检测错误增加,车辆的当前位置不连续地改变。 指定旅行路与过去指定旅行路的历史之间的连续性损失。 指定正确的入口IC失败。 即使在这种情况下,根据在连续性丢失之前指定的行驶道路来指定正确的入口IC。 基于指定的入口IC和IC来计​​算通行费用,车辆接近车辆并通过该IC通过车辆离开收费公路。 如果在通过入口IC时指定了引导路线,则从旅行道路和引导路线适当地指定正确的入口IC。

    • It is desired to form a flange and roller guide surfaces on each retainer of a self-aligning roller bearing easily and with high precision. Each punched retainer include a large-diameter annular portion (1), a small-diameter annular portion (2), a plurality of bridges (3) extending between the annular portions (1) and (2) and defining a plurality of circumferentially separated pockets (4) therebetween, roller guide surfaces (1a) that can be brought into sliding contact with end surfaces of respective convex rollers (5), which revolve around the axis of the bearing, and a flange (6) formed by radially bending the large-diameter annular portion (1). The roller guide surfaces (1a) comprise punched sections formed on the portions of the inner peripheries of the pockets (4) located at the large-diameter annular portion (1), and the flange (6) has a Bent Portion® that extends the entire circumference of the large-diameter annular portion (1). With this arrangement, the roller guide surfaces (1a) can be formed by punching only, which is a essential step. This makes it possible to make uniform the flatness of the back and front surfaces of the flange and its bent angle over the entire circumference thereof.
    • 希望在自调心滚子轴承的每个保持器上容易且高精度地形成凸缘和滚子导向表面。 每个冲压保持器包括大直径环形部分(1),小直径环形部分(2),在环形部分(1)和(2)之间延伸并限定多个周向分离的多个桥 在其间的凹穴(4),能够与围绕轴承的轴线旋转的各个凸轮(5)的端面滑动接触的滚子引导表面(1a)和通过径向弯曲形成的凸缘(6) 大直径环形部分(1)。 滚子引导表面(1a)包括形成在位于大直径环形部分(1)的凹穴(4)的内周的部分上的冲压部分,并且凸缘(6)具有弯曲部分 大直径环形部分(1)的整个圆周。 通过这种布置,滚子引导表面(1a)可以仅通过冲压形成,这是必要的步骤。 这使得可以使凸缘的后表面和前表面的平整度及其整个圆周上的弯曲角度均匀。
