Abstract: A tractor or trailer axle replacement spindle and seal ring assembly includes a spindle with an elongate cylindrical body having bearing surfaces and threads. The seal ring is a shorter cylindrical component having an opening sized to achieve an interference fit with the spindle. The exterior surface of the spindle and the interior surface of the ring seal include complementary oblique, shoulders bounded by regions of constant diameter. The spindle also includes a shoulder or flange at its end opposite the threads which positively axially locates the seal ring thereon. When the two components are to be assembled, the seal ring is heated to several hundred degrees Fahrenheit and slid onto the spindle until the seal ring contacts the shoulder or flange on the spindle.

Abstract: An axle boring assembly includes a portable power head or drive unit, a bearing pack to which the drive unit is attached, an adjusting base to which the bearing pack is adjustably secured and a mounting assembly which fits over a motor vehicle axle and to which the adjusting base is secured. The mounting assembly comprises a first section having axially spaced apart front and rear clamps and a substantially identical second section with matching spaced apart front and rear clamps. Threaded fasteners extend between the front and rear clamps and may be rotated to secure the mounting assembly about the end of the axle. Each clamp includes jaws which contact the axle and which may be selected from sets of various sizes and configurations to ensure accurate and suitable engagement of the axle.

Abstract: A replaceable replacement spindle assembly for both drive (tractor) axles and trailer axles comprises a spindle and seal ring. The spindle is an elongate cylinder having inner and outer bearing surfaces and a threaded portion at one end. The seal ring is a short annular or tubular component having a circular opening sized to achieve an interference fit on a portion of the spindle adjacent the inner bearing surface. The interfering surfaces of the spindle and the seal ring are complementarily dimensioned and tapered so that the surfaces contact when the spindle is properly positioned in the seal ring. Adjacent the end of the spindle opposite the bearing surfaces and threads is an end region with features such as openings or a channel which receive complementary fasteners such as plugs, short bolts or a through bolt.

Abstract: A shaft roundness gauge measures the roundness (or lack thereof) of a surface such as a bearing surface of a shaft or axle of a truck, tractor or trailer. The gauge comprehends a plurality of specifically sized rings or collars having inner diameters which correspond to common outside diameters of shafts, axles and other circular or cylindrical components. The ring includes a radial opening which receives a collet fitting which receives a probe housing of a dial indicator. A collet clamp may be tightened to secure the dial indicator to the ring. The ring and dial indicator are positioned on a shaft, at that position where the shaft or component is believed to be least worn. The dial indicator is zeroed and then the assembly is rotated around the shaft or component to determine, by the reading of the dial indicator, the location of and the extent of wear of the shaft or component.

Abstract: A honing tool or device having a generally cylindrical body includes a plurality of axially extending webs to which are attached a like plurality of curved honing blades. A portion of the external surface of each blade remote from the attachment point includes an abrasive coating. The radius of curvature of the portion of the blades including the abrasive coating is nominally the same as the radius of the desired finish diameter of the bore. Resilient dampers are disposed behind the blades in the body to dampen vibrations. An additional plurality of webs may be disposed behind the blades to limit their inward translation. A double or tandem honing device includes a pair of the just described honing tools which are arranged in axially spaced apart relationship on a common shaft.

Abstract: An improved replacement axle spindle includes a cylindrical wall exhibiting increasing thickness at increasing distances from the inner end which is secured to an axle. The wall thickness increases in correspondence with the load borne by the replacement spindle resulting in no loss of necessary strength and load carrying ability. Several different profiles are embodied in the present invention: a first embodiment utilizes a straight internal taper; a second embodiment utilizes a dual internal taper, first at a small angle and then at a larger angle; another embodiment utilizes a parabolic internal taper and yet another embodiment utilizes a straight external taper. All may be utilized to replace a tractor or a trailer axle spindle. The spindles save weight and facilitate lubricant flow from the tractor differential into the axle roller bearing assemblies after a repair procedure.

Abstract translation: 改进的替代轴心包括圆柱形壁，其在​​与固定到轴上的内端的距离增加的距离处呈现增加的厚度。 壁厚随着更换主轴承受的负荷而增加，不会损失必要的强度和承载能力。 在本发明中体现了几种不同的轮廓：第一实施例利用直的内锥度; 第二实施例首先以小角度然后以较大的角度利用双内锥度; 另一个实施例利用抛物线内锥度，另一实施例利用直的外锥度。 所有这些都可以用于更换拖拉机或拖车轴主轴。 主轴节省重量，并在维修程序之后促进润滑剂从拖拉机差速器流入车轴滚子轴承组件。

Abstract: A fixture for replacing brake spiders on heavy duty vehicle and truck axles includes an assembly with a flat reference surface and two internal bores just slightly larger than the respective inner and outer bearing surfaces on the axle having a damaged brake spider. The fixture may have specifically sized bores or may include a plurality of collars which can be utilized in pairs and mounted and retained within the fixture. The fixture also includes longitudinally adjustable rods or fingers extending therefrom which include blind threaded bores. During attachment of the new brake spider, threaded fasteners are inserted into the blind bores to temporarily and properly position the brake spider on the fixture and axle.
