摘要： Differential case includes multiple oil intake holes being respectively at positions offset from intermediate point between two pinions adjacent peripherally in the case toward the pinions, the holes passing through outer peripheral wall of the case in inside-outside direction and being capable of taking lubricant oil into the case. The holes are formed such that as seen in projection plane orthogonal to rotation axis of the case, axes of the holes extending from inner to outer opening ends of the holes are inclined forward in rotational direction of the case when vehicle travels forward. As seen in the projection plane, the pinions are placed outside areas between first and second imaginary lines, the first imaginary lines joining the axis and one peripheral ends of the inner opening ends, the second imaginary lines joining the axis and the other peripheral ends thereof.

摘要： An input member of a differential device includes a step portion in a side surface on a carrier side of an outer peripheral end portion of the input member, the step portion being recessed in a direction opposite to the carrier, extending to a radially-outer end surface of the outer peripheral end portion of the input member, and being capable of abutting against the carrier. Accordingly, when welding the input member and the carrier supporting a planetary gear, a degree of freedom of processing and welding workability are improved and the differential device is reduced in size. Moreover, grinding and finishing of a welding bead are unnecessary, and therefore manufacturing cost is suppressed.

摘要： A dog clutch that transmits driving force from a driving-side rotating body to a driven-side rotating body. In the bottom face of recessed parts formed in the driving-side rotating body there is a strip-shaped island part protruding from the bottom face in the circumferential direction, and there are groove parts between the island part and torque-receiving surfaces. The groove parts and the bottom face are formed by a forging mold, and their surfaces are forged mill scale. The island parts have a cut surface, which is formed by cutting the top part of the islands after they have been formed by the forging mold, and which receives the tip surface of a protruding part. The groove parts are formed so as to be deeper than the bottom face, and the cut surface is formed as to be shallower than the bottom face.

摘要： In a differential device distributing rotational force acting on a differential case to a pair of output shafts, the differential case including an input member and a cover portion, assembling precision of the differential device is enhanced by suppressing strain due to welding and press-fitting. The input member includes: a welded portion fitting the cover portion in axial direction and joined by welding; a press-fitted portion located inward of the welded portion in radial direction and axial direction and press-fitted to the cover portion; and a connecting surface connecting the welded portion and the press-fitted portion and forming a space between the connecting surface and the cover portion; the space allowing deformation of the press-fitted portion during press-fitting. The connecting surface includes one end portion continuous to the welded portion and extending outward from the welded portion in radial direction.

摘要： In a differential device, side gears include: shaft portions; and intermediate wall portions each formed in a flat ring plate shape orthogonal to an axis of output shafts and integrally connecting between the shaft portions and toothing portions separated outward from the shaft portions in a radial direction of an input member, respectively. At least part of each intermediate wall portion is formed as a thin portion having an outside surface retreating axially inward from a backside of the tooting portion. A side wall portion of a cover portion integrally includes an outer-periphery-side side wall portion having an inside surface facing the backside of the toothing portion, and an inner-periphery-side side wall portion having an inside surface facing a backside of the intermediate wall portion. At least part of the inner-periphery-side side wall portion is formed thicker than the outer-periphery-side side wall portion and protrudes toward the thin portion.

摘要： In a differential device, an outer tube portion is formed in one of a side gear and a sleeve, and an inner tube portion fitted to an inner periphery of the outer tube portion is formed in the other. A falling-off prevention device for preventing axial relative movement of the outer and inner tube portions is provided between the outer and inner tube portions. A seal member for shutting off communication between the falling-off prevention device and an inside of a differential case is set in a fitting portion between the outer and inner tube portions. Accordingly, lubricating oil in the differential case is prevented from leaking out of a space between the side gear and the sleeve without performing a special process such as pressure welding or adhesive bonding during assembly and which has good ease of assembly.

摘要： A gear inspection apparatus includes a distance measurement device, a value search part, a difference calculation part, a selecting part, a judgment value determination part, and a judgment part that are connected together in the named order. A raw waveform obtained by the distance measurement device is converted by the value search part into a rectangular waveform of maximum value and a rectangular waveform of minimum value for each prescribed number of gear teeth, and a difference between the maximum value and the minimum value is calculated by the difference calculation part. The difference is converted into a nick determination value by the judgment value determination part, and the presence or absence of a nick is determined by the judgment part.

摘要： A ball joint includes a retaining ring fitted to a shank of a ball stud, and a boot having first and second annular beads fitted to the retaining ring and a ball socket. The first mounting bead is formed with an end face seal portion and an inner periphery seal portion, which are adapted to come into close contact with a cylindrical portion and a large flange of the retaining ring, respectively. In such a ball joint, a clearance is provided between the first mounting bead and the small flange for permitting the movement of the first mounting bead toward the small flange. Thus, even when the ball stud and the ball socket are swung relative to each other in a state in which the boot has been hardened due to the freezing of snow deposited to the boot and the like, the generation of an excessive stress in the mounting bead of the boot can be avoided.
摘要翻译：球形接头包括装配到球头螺柱的柄部的保持环，以及具有装配到保持环上的第一和第二环形胎圈的靴子和球窝。第一安装凸缘形成有端面密封部分和内周密封部分，其分别与保持环的圆柱形部分和大凸缘紧密接触。在这种球形接头中，在第一安装凸缘和小凸缘之间设有间隙，以允许第一安装凸缘朝向小凸缘移动。因此，即使在由于冻结在雪靴等上的雪而导致靴子硬化的状态下，球杆和球窝彼此相对摆动，因此在安装中产生过大的应力引导珠可以避免。

摘要： In a bevel gear pair, a first gear and a second gear are applied with tooth top modification, and a ratio of a distance from a pitch circle to a starting position of the tooth top modification to a distance from the pitch circle to a tooth top in the first gear is larger than a ratio of a distance from a pitch circle to a starting position of the tooth top modification to a distance from a pitch circle to a tooth top in the second gear. Thus, the bevel gear pair that can achieve smooth meshing is provided.
