Abstract: Disclosed herein is a method of truing and angling the blades of a form-relieved face mill cutter during the blade sharpening process thus eliminating a separate time-consuming procedure for truing and angling. The position of the cutting edge of each blade is determined and a reference blade is selected. The sharpening plane of each remaining cutting blade is repositioned, if needed, such that after removing stock material from the blades in accordance with the newly repositioned sharpening plane, the cutting edge of each blade will follow essentially the same path when the cutter is rotated about its axis.

Abstract: A method of sharpening cutting blades of the type made from bar stock type material, the method comprising producing relief surfaces on the cutting profile surface. The method comprises forming first and second relief surfaces (95, 96) on the cutting profile surface. The first relief surface (95) extends from a location inward of the cutting edge (62) to the back face (55) and is oriented at a first relief angle ( beta R) with respect to a side surface (54). The second relief surface (96) extends from the cutting edge (62) to the first relief surface (95) and is oriented at a second relief angle ( beta ) with respect to the side surface (54) with the second relief angle ( beta ) being smaller than the first relief angle ( beta R). The cutting blades may comprise a base portion (51) and a cutting end (52), or, the cutting blades may have a uniform cross section along their length with the front surface of the cutting blade comprising a pair of mounting surfaces (148, 150), rake surface (152) and connecting surface (154). The cutting surface may include a protuberant portion (80) adjacent the top surface (64) of the cutting blades, the protuberant portion (80) also including the first and second relief surfaces (90, 91).

Abstract: A differential gear assembly of the type including worm or helical-type gears mounted on crossed non-intersecting axes is provided wherein a pair of drive axles (12, 14) are received in bores (10) formed in the sides of a differential housing (4), and wherein axially aligned worm or side gears (18, 30) are coupled to each axle end for meshing engagement with torque transfer gears within said housing. One of the side gears (30) is provided with an outwardly directed flange (36) which overlaps an inwardly directed flange (42) associated with the housing to maintain the end faces of the side gears (18, 30) out of contact with each other to preclude axial thrust forces developed in one side gear (30) from passing to the other (18) and to eliminate frictional forces at the interface of the side gears, thereby reducing differences in bias ratios associated with opposite directions of differentiation without significantly reducing the overall bias ratio of the assembly.

Abstract: Disclosed herein is a process and apparatus for grinding tooth surfaces of spur and helical gears by a generating method. The outer tooth surfaces (4) of a theoretical ring gear (6) are conjugate to the grinding surfaces (3) along the width of a generally hourglass shaped grinding wheel (2). The grinding wheel (2) is rotated which in turn causes the theoretical ring gear (6) to rotate. A work gear (8) is rotated in mesh with the internal tooth surfaces (10) of the theoretical ring gear (6) and simultaneously is traversed in mesh across the width of the grinding wheel (2) with the center of the work gear (Xw) moving in a path (12) about the center of the theoretical ring gear (XI).

Abstract: A differential gear assembly for vehicles is provided wherein a pair of drive axles (12), (14) are received in bores (10) formed in the sides of a differential housing (4), and wherein axially aligned worm or side gears (18, 18') are coupled to each axle end for meshing engagement with torque transfer gears (20) within said housing. A non-rotatable washer element (30) is inserted between confronting end faces of the side gears (18, 18') to reduce the sliding velocity between the washer and each side gear to one-half of the relative sliding velocity between the side gears, thereby reducing and/or controlling friction between the side gears and reducing differences in bias ratios associated with opposite directions of differentiation.
