摘要： A fixturing device for holding a workpiece for processing by an induction hardening machine includes a first subassembly constructed and arranged to be attached to an induction coil subassembly which is movable into and out of position around the workpiece. A second subassembly, virtually identical in construction to the first subassembly, is attached to the induction coil assembly and the two subassemblies are spaced apart so as to face one another and so as to define therebetween a workpiece-receiving region. Each subassembly includes an L-shaped bracket with one leg configured for attachment to the induction coil assembly and the other leg configured with connecting rods for attachment to a holding block. There are three connecting rods, two in the form of cylindrical pins, and one, the center connecting rod, being externally threaded for connecting a holding block to the L-shaped bracket. The two cylindrical pins receive coil springs so as to spring bias the holding block. The threaded connecting rod receives a hex nut for setting the initial spring tension of the holding block relative to its movement toward the L-shaped bracket. The workpiece to be processed by the induction hardening machine is to be positioned between upper and lower centers. The procedure for utilization of the fixturing device is to place the workpiece on the lower center and then push the upper portion of the workpiece in between the two holding blocks, allowing these blocks to separate for added clearance by compressing the coil springs in each subassembly until the workpiece is properly aligned, at which point the upper center is lowered into position.

摘要： An induction hardening apparatus for inductively heating and quench hardening a crankshaft includes an arrangement of two workstations similarly configured and a robotic device indexing the crankshaft from a first workstation to a second workstation. The induction hardening apparatus is designed with a single induction coil located at the first workstation for the sequential induction heating and quench hardening of the pins of the crankshaft. At the second workstation, a single induction coil is used for the bearing surfaces of the crankshaft. One feature of the present invention is that the induction coils do not contact the surfaces of the crankshaft which are being inductively heated and quench hardened. Crankshaft dimensions and geometry are programmed into servodrive systems which move the corresponding coil in X and Y directions accurately tracing the orbit or path of each pin and each bearing surface. Another feature of the present invention is the use of an offset 180 degree coil which provides improved heating patterns in less time than traditional 90 degree coils.

摘要： A centering spindle for use with a workpiece which is to be induction hardened includes a generally cylindrical outer housing into which a shaft is positioned and mounted in spaced relation to the housing by a bearing arrangement. The bearing arrangement allows the shaft to rotate relative to the housing. The end of the shaft extending out of the housing is connected to an isolation spacer which is fabricated out of an electrical insulator material. The isolation spacer in turn is attached to a removable tip which is constructed and arranged for interfacing with the workpiece to be induction hardened. The design of the centering spindle is such that the tip may be removed and replaced when it becomes worn without the need to replace any of the other parts or components of the centering spindle. Further, any electromagnetic field induced in the workpiece and transmitted to the tip will not be transmitted to the shaft nor to the bearing arrangement due to the isolation spacer. Additionally, any substantially elevated temperature which is experienced by the tip due to the heating of the workpiece will be insulated to some extent from reaching the shaft due to the thermal insulation properties of the material used for the isolation spacer.
摘要翻译：与被感应淬火的工件一起使用的定心心轴包括大致圆柱形的外壳，轴通过轴承装置与轴承座间隔开地安置在轴中。轴承装置允许轴相对于壳体旋转。延伸出壳体的轴的端部连接到由电绝缘体材料制成的隔离间隔件。隔离垫片依次连接到可移除的尖端，其可构造和布置成与工件接合以进行感应淬火。定心心轴的设计是这样的：当刀头磨损时可以移除和更换刀片，而不需要更换定心心轴的其他部件。此外，由于隔离间隔件，在工件中感应并传递到尖端的任何电磁场将不会传递到轴或轴承装置。此外，由于工件的加热而由尖端经历的任何基本上升高的温度将由于用于隔离间隔物的材料的绝热性能而在一定程度上被绝缘到达轴。

摘要： A hydrostatic transmission having a pump and a motor of the radial piston type with each cylinder slipper bearing rotatably supported by a hybrid or combination hydrostatic and hydrodynamic bearing on an internal bearing. The hydrostatic bearing component has a restricted port connecting hydrostatic pressure fluid from the cylinder to supply a distribution recess in the slipper bearing surface for hydrostatic pressure feed of the fluid film providing hydrostatic balancing pressure gradient between the slipper and internal bearing to balance a high percentage of the hydrostatic pressure load and to meet flow requirements for low speed operation. The hydrodynamic bearing component has a low pressure source to spray fluid on the internal bearing, annular dams on each side retaining fluid on the internal bearing, and a taper at the leading edge of the slipper bearing to force fluid into the bearing clearance and provide a hydrodynamic balancing pressure component and fluid flow increasing with speed to balance the centrifugal load and effect balancing of the remaining hydrostatic load and to meet flow requirements which increase with speed. The total hydrostatic and hydrodynamic balancing pressure balances the total load.
