Abstract: A differential barrel includes a body having a first end, a second end, and an intermediate portion extending therebetween. A ring gear support member extends outwardly at the second end. A ring gear support surface forms a first section of the intermediate portion. The ring gear support surface defines a first outer diameter of the intermediate portion. A ring gear alignment surface forms a second section of the intermediate portion. The ring gear alignment surface defines a second outer diameter of the intermediate portion. A ring gear is mounted to the outer surface of the body and includes an inner annular surface including a first region defining a first inner diameter and a second region defining a second inner diameter. The first region establishes an interference fit with the ring gear support surface. The second inner diameter is no more than about 0.05-inches (1.27-mm) greater than the second outer diameter.

Abstract: A differential housing includes a body including an outer surface. The body has a first end, a second end, and an intermediate portion extending therebetween. A ring gear support member extends outwardly of the body at the second end. A ring gear support surface forms a first section of the intermediate portion. The ring gear support surface defines a first outer diameter of the intermediate portion. A ring gear is mounted to the outer surface of the body. The ring gear includes an inner annular surface having a first region defining a first inner diameter and a second region defining a second inner diameter. The first region includes a sawtooth profile to establish a desired alignment of the ring gear and the body and the second region facilitating an interference fit with the ring gear support surface.

Abstract: A rotational coupling arrangement, such as for use with a vehicle, is provided. The coupling arrangement includes a first rotational component have at least one straight groove, the groove having a sidewall. A second rotational component is coupled to the first rotational component, the second rotational component having at least one projection. The at least one projection having a linear profile between a first end and a second end, the at least one projection having a first section adjacent the first end and a second section adjacent the second end. The first section is sized to define a first gap between the first section and the sidewall, the second section being sized to define a second gap between the second section and the sidewall. The second gap is smaller than the first gap.
Abstract translation: 提供了一种诸如用于车辆的旋转联接装置。 联接装置包括具有至少一个直槽的第一旋转部件，该凹槽具有侧壁。 第二旋转部件联接到第一旋转部件，第二旋转部件具有至少一个突出部。 所述至少一个突起在第一端和第二端之间具有线性轮廓，所述至少一个突起具有与所述第一端相邻的第一部分和与所述第二端相邻的第二部分。 第一部分的尺寸设置成限定第一部分和侧壁之间的第一间隙，第二部分的尺寸设定成在第二部分和侧壁之间限定第二间隙。 第二间隙小于第一间隙。
