Abstract: A tapered bearing (306) for the drive drum assembly (100) of a belt grinding machine (10) that employs multiple, parallel, abrasive grinding belts (76), and back-up shoes (122) for pressing the belts (76) against the surfaces on a workpieces (46) to be ground. The drive drum assembly (100), in cooperation with small pulleys (120, 124) operatively associated with the contouring head (108), keeps the abrasive belts (76) properly trained. The central shaft (148) of the drive drum assembly (100) is secured between a fixed bearing support (160) and a laterally movable support bracket (142). A tapered bearing (306) is fastened to one end of the shaft, and a complementary shaped aperture (314) is defined in a spindle (312) retained in the movable support bracket (142). When the movable support bracket (142) is shifted inwardly, the tapered bearing (306) fits snugly into the aperture (314) so that the drive drum assembly (100) is supported in a rigid, sag-free manner. This "pre-loads" the drive drum assembly (100) and bearing assembly (330), so the assemblies rotate smoothly, without slippage. Seals (324) are provided about the tapered bearing (306) so that dust and debris cannot degrade the bearing (306), and the bearing (306) does not wear excessively, even under prolonged, high speed operation.

Abstract: A grinding machine provided with a spindle (5) rotating under the influence of a cantilever mounted rare earth permanent magnet motor (40). Hydrostatic fluid film bearings (41, 42) are provided between the ends of the spindle (5) and a bronze bearing (64, 65) to support spindle (5) in such a manner so as to eliminate wear. A single oil reservoir (20) is used to supply oil to the hydrostatic bearings (41, 42), as well as to the cooling jacket labyrinth (17) of the motor (40).

Abstract: A method of forming a hydrostatic nut (36) that cooperates with a lead screw (38) for translating a cam grinder wheel head (26). An externally threaded lead screw master (66) is inserted into an internally threaded cylindrical mold (50). Beads of wax or tape (76, 78) are adhered to the external threads on the standard (66) while the rest of the standard (66) is treated with a release coating to define a continuous cavity (86, 88) between the internal threads of the nut (36) and the external threads on the standard (66). An epoxy resin is introduced into the cavity. The standard (66) is then removed and the wax or tape (76, 78) is removed to leave oppositely directed helical channels (86, 88) in the polymer. The helical channels are pressurized with a thin fluid film that prevents metal to metal contact.
