摘要： PROBLEM TO BE SOLVED: To provide a zero-clearance bolted joint for use in joining a ring gear to a differential case.SOLUTION: A bolted joint is formed by using a bolt 20 having a tapered shoulder 44 to cold form a deformable sleeve 46 in order to provide a "zero-clearance" fit. Specifically, preferably a plurality of bolted joints are used to join the ring gear 42 to the differential case 58. As the bolts are installed into the differential case 58 and ring gear 42, the tapered shoulders 44 on the bolts 20 dilate the deformable sleeves 46 until outer diameters of the sleeves 46 contact internal walls of through holes 56 in the differential case 58.

摘要： PROBLEM TO BE SOLVED: To provide a method of forming a thread forming screw, which can form threads in a workpiece having a surface hardness which exceeds HRC 23.SOLUTION: The method of forming a thread forming screw includes the steps of: cold upsetting an alloy wire to form a screw head, and then forming a screw thread part; carbon enriching the screw to at least a 0.48 carbon level, and then quenching and tempering the screw, wherein the screw is tempered such that the surface hardness does not exceed the core hardness by more than 3 Rockwell C points, and both the surface and core are at a Rockwell C33-C39 hardness; induction hardening the point; quenching and tempering the screw again, wherein the screw is tempered such that the lead threads and the first 3-4 full threads are at a Rockwell C56 minimum hardness, preferably to a depth of at least 0.008 inches, and the core is at the Rockwell C33-C39 hardness; and finally, applying a finish.
摘要翻译：要解决的问题：提供一种形成螺纹形成螺杆的方法，该螺纹形成螺杆可以在具有超过HRC 23的表面硬度的工件中形成螺纹。解决方案：形成螺纹形螺杆的方法包括步骤：冷镦合金丝以形成螺丝头，然后形成螺纹部分; 碳将螺杆富集至少0.48碳水平，然后淬火和回火螺杆，其中螺杆被回火，使得表面硬度不超过芯部硬度超过3个洛氏C点，并且表面和芯部处于洛氏C33-C39硬度; 感应淬火点; 再次对螺钉进行淬火和回火，其中螺杆被回火，使得引线和前3-4个全螺纹处于洛氏C56最小硬度，优选至少为0.008英寸的深度，并且芯在洛氏 C33-C39硬度; 最后应用完成。版权所有（C）2013，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an improved drive socket design for a holding and drive fastening tool.
SOLUTION: A driving tool 100 has the drive socket 102. The drive socket 102 has alternating longitudinal grooves 104, lobes 106, and conical zones 108. The lobes 106 are not tapered in the conical zones 108 of the drive socket 102, and each has a uniform width to the edge 110 of the drive socket 102. The lobes 106 have uniform widths in the conical zone 108 of the drive socket 102, thereby engaging with the longitudinal grooves of the conical zones of the fastening tool.
