摘要： Apparatus capable of performing wet and dry machining processes such as a hobbing machine for producing spur and helical gears, shafts, splines, and the like, by wet and dry hobbing methods. The apparatus comprises means to remove metal chips resulting from the wet and dry machining processes from the apparatus via respective independent wet and dry chip outlets. The chip removal means comprises a transfer means located in the machine base with the transfer means being reversible in direction in order to convey metal chips, emanating from the machining process, to the respective wet or dry chip outlet. The chip removal means enables metal chips from wet machining processes to be conveyed to and discharged from an outlet in one side surface and metal chips from dry machining processes to be conveyed to and discharged from an outlet in another side surface.

摘要： A multi-purpose probe module 82, comprising both a touch-trigger type contact probe 84 and a non-contact type probe 86, is used in method and apparatus for monitoring and adjusting the accuracy of a computer-controlled machine for manufacturing precision bevel and hypoid gears. The probe module is mounted on the machine's tool support and is used in conjunction with locating points positioned on the machine's work support to monitor and recalibrate the relative positions of the tool and work supports. The probe module is also used to monitor the flanks of the gear-shaped workpieces (a) for initial stock division, (b) for pre-machining accuracy, (c) for first-piece testing, (d) for in-process accuracy, and (e) for post-machining accuracy. The same probe module is used in combination with a sacrificial test wafer mounted on the work support for adjusting the position of the machine's cup-shaped grinding wheel following each dressing of the latter's working surfaces.

摘要： A tool, for dressing both the inside and outside working surfaces of cup-shaped abrasive wheels used for grinding gears, is disclosed along with methods and apparatus for using the tool. The working portion of the dressing tool has a cylindrical shape with an outside surface parallel to its axis of rotation and a top surface extending radially, to the axis of rotation. The apparatus orients the tool relative to the grinding wheel so that only the outer cylindrical surface of the tool is used to dress the inside working surface of the grinding wheel, while only the top surface of the tool is used to dress the outside working surface of the wheel. Formulas are provided for calculating the optimum radius of the cylindrical surface of the tool for providing substantially equal effective relative curvatures between the tool and each of the respective sides of the grinding wheel, thereby resulting in similar grinding characteristics being dressed into both the inside and outside working surfaces of the grinding wheel.

摘要： Method and apparatus for stock dividing gear-shaped workpieces mounted on the work spindle of a gear-finishing tool. A work spindle encoder provides instantaneous angular position information when the surface of leading and trailing flanks of the workpiece teeth are sensed by a probe. This instantaneous position information is used to generate two sets of measured error values which relate, respectively, to the leading and trailing flanks and which are indicative of the differences between the sensed surrfaces and the desired surfaces of a correctly-sized gear. These sets of error values are analyzed using fourier transform techniques to generate (a) a first harmonic for each set and (b) a set of modified error values for each leading and trailing flank corresponding to each respective first harmonic. The largest and smallest modified error values of each set are used to simulate the opposite sides of the largest and smallest "effective" (as different from "actual") tooth spaces of the unfinished workpiece, and these effective spacings are compared to the desired correctly-sized tooth space of a finished gear to generate a correction value for adjusting the angular position of the workpiece relative to the finishing tool prior to initiation of the finishing process. In the preferred embodiment, a non-contact probe is used for sensing the flanks of the workpiece so that the entire stock division procedure takes only a relatively few seconds.

摘要翻译： 安装在齿轮精加工工具的工作轴上的齿轮状工件的分割方法和装置。 工件主轴编码器在通过探头感测工件齿的前后侧面的表面时提供瞬时角位置信息。 该瞬时位置信息用于产生两组测量的误差值，这两组测量误差值分别与前导和后部侧面相关，并且表示感测到的表面与正确尺寸的齿​​轮的所需表面之间的差异。 使用傅里叶变换技术来分析这些误差值集合，以产生（a）每个集合的一次谐波，和（b）对应于每个相应的第一谐波的每个前导和后端的一组修正的误差值。 每组的最大和最小的修正误差值用于模拟未完成工件的最大和最小“有效”（与实际“不同于”实际“）齿空间的相对侧，并将这些有效间距与正确地进行比较 成品齿轮的齿形间距产生用于在开始精加工之前调整工件相对于精加工工具的角位置的校正值。 在优选实施例中，使用非接触式探针来感测工件的侧面，使得整个分割程序仅需要相对较少的秒。

摘要： A method of forming a relief at the toe end of the teeth on a bevel gear is disclosed. The width of the blades that cut the longitudinally extending convex or concave profiles of the flanks of the teeth is increased to a dimension greater than the width of the tooth slot at the toe end whereby additional stock is removed from the toe end of the flank opposite the flank being cut by the blades. The relief is formed at the toe end of each tooth with the relief being on the same flank profile for all teeth. Lapping interference is eliminated. A separate chamfering operation is not required.

摘要： An improved cutting tool intended primarily for gear cutting operations and a method of manufacturing this new tool. The tool is of a type formed from a length of bar stock and may be resharpened while preserving metallurgical or other treatments on front cutting faces of the tool. The improved tool also includes a base mounting portion and a cutting end. A first cutting face is formed in part of the length of the tool and a second cutting face is formed throughout substantially the full length of the tool in a way that preserves important mounting surfaces in the base portion of the tool.

摘要： A differential gearing assembly including a differential case 10 that mounts axle drive gears 22 rotatably engaged with axles 20 and transfer gearing 50 for cross coupling the axle drive gears. The axle ends are secured to the differential assembly by lock rings 32 received by lock ring grooves formed on the axle ends. A thrust spacer maintains the predetermined spaced apart position of the axle ends and in one embodiment 26 comprises elements 26a 26b which when joined together by a fastener 28 capture the lock rings in their installed positions on the axle ends. The transfer gearing includes transfer gears 50 rotatably coupled to each other by intermediate gearing 54. In an alternate embodiment, a thrust spacer 70 is bisected along a line defined by stepped confronting surfaces 74a, 74b, 74c to define interfitting halves 72a, 72b. Each half is configured and sized to facilitate removal through an opening defined between the intermediate gears. The inclination angles of the teeth on the axle drive gears 22 are equal but opposed so that equal and opposed thrust forces are exerted on the differential case.
