摘要： Disclosed herein is a rotary cutter for cutting gears and the like. The rotary cutter has an axis of rotation and comprises a disc-shaped cutter head having a circumferential edge surface. The cutter head further includes an inner wall surface located radially inwardly with respect to the edge surface and being concentric about and extending parallel to the axis of rotation. The rotary cutter further includes a cutter ring located on the cutter head. The cutter ring has at least one stock removing surface located on a base portion with the base portion having an inside ring surface, an outside ring surface, and a base surface with the outside ring surface being perpendicular to the base surface. The cutter ring is in a radially expanded condition whereby the outside ring surface is seated against the inner wall surface of the cutter head and the base surface is seated against the first surface of the cutter head. The cutter ring is expanded by an expanding means located within the cutter ring and contacting the inside ring surface. The expanding means effects and maintains the cutter ring in a radially expanded position whereby the cutter ring is centered on the cutter head concentrically about the axis of rotation.

摘要： 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.

摘要： A differential gear assembly for vehicles is provided between 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.

摘要： 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 on the cutting profile surface. The first relief surface extends from a location inward of the cutting edge to the back face and is oriented at a first relief angle with respect to a side surface. The second relief surface extends from the cutting edge to the first relief surface and is oriented at a second relief angle with respect to the side surface with the second relief angle being smaller than the first relief angle. The cutting blades may comprise a uniform cross-section and the cutting profile may include a protuberant portion adjacent the top surface of the cutting blades.
