  • Patent number: 8826542
    Abstract: In summary, the invention relates to a method for forming an end-side toothing arrangement of a roiling bearing, in particular a wheel bearing. The aim is to improve the uniformity of the end-side toothing arrangement and to allow a greater tooth depth. This is achieved by two method steps in that, in a first step before the reshaping of an end piece of a hub, a die is axially arranged on the rolling bearing in a preassembled state and, in a second step during the reshaping of the end piece and the shaping of the end-side toothing arrangement, the die radially delimits a radial recess of the rolling rivet collar as it forms. In addition, the die reduces or prevents radial widening of the inner ring.

    Abstract: An epicyclic gear assembly has a central toothed sun gear unit mounted on a carrier plate and plurality of planetary gear sets surrounding the central gear in torque-transmitting relationship. Each of the planetary gear sets has a toothed planet gear supported by a planet shaft, the first end of which is cantilevered from the carrier plate. A second end of the planet shaft supports the planet gear. A double-tapered concave middle portion of the planet shaft allows flexing of the shaft so as to facilitate elastic deflection of the planet shaft while distributing load between the planet gear sets. The outer circumference of the middle portion has a pair of spaced outwardly convex protrusions formed between the first end and the second end.

  • Publication number: 20120132739
    Abstract: A moveable shaft assembly including a frame, a first shaft, and a first drive assembly. The frame includes a first support wall and a second support wall opposite the first support wall. The first shaft includes a drive end and a support end and defining a first axis therebetween. The first shaft extends between the first support wall and the second support wall. The first drive assembly rotates the first shaft about the first axis, and the first drive assembly is coupled to the drive end of the first shaft. The first shaft and first drive assembly are moveable relative to the frame in response to a reaction force acting on the first shaft in a direction oblique or transverse to the first axis.

  • Publication number: 20120115673
    Abstract: The objective of the invention is to provide a fast way to adjust endplay on output shaft without removing entire output shaft gear train assembly. One embodiment of the present invention is to place the shims in new location between the outer most ring gear hub and the ring gear stop on the output shaft. The new shims will have spines so they can be placed between the output stop and the ring rear hub. Another embodiment of the present invention, a preferred method to adjust endplay is to use a @ Torrington thrust bearing between the transmission case and output shaft. This will prevent reoccurring endplay adjustments from wear.

  • Publication number: 20120083346
    Abstract: A method of testing a fusion weld for a shaft includes producing two shaft subsections, wherein the shaft subsections are symmetrical and faun a cylinder coaxially along the axis of rotation. Core regions of each shaft subsection are removed in order to produce open recesses in the cylinder within remaining tubular webs. The two shaft subsections are positioned coaxially one on top of the other, wherein the two remaining webs are mutually adjacent and the two open recesses form a hollow space. A first tubular ring seam is produced by narrow-gap arc welding and in one of the two shaft subsections a passage from outside into the hollow space is produced. Further, a quality of the first tubular ring seam within the hollow space during and/or after the welding operation is evaluated by a detection device or radiation source which is introduced through the passage into the hollow space.

A ratio of a minimum diameter (D3min) of the smooth portion (3) to a minimum diameter (D2min) of the torque-transmission teeth portion (2) is set to 0.9 or more and 1.02 or less. Further, the torque-transmission teeth portion (2) and the smooth portion (3) undergo heat treatment so as to from a heat-treated hardened layer (4). The heat-treated hardened layer (4) is formed to increase in depth from a side of the torque transmission teeth portion (2) to a side of the smooth portion (3).
