摘要： A method for precision machining a workpiece with gearing, wherein teeth of a gear-cutting tool rotating about a rotation axis are brought into engagement with teeth of the workpiece rotating about a workpiece rotation axis, and the gear-cutting tool and the workpiece are moved relative to each other in an axial direction parallel to the workpiece rotation axis. The thickness of the teeth of the gear-cutting tool, starting from an end face, increases in the axial direction until a thickness maximum is reached. The ratio (Bw/Bz) of the width (Bw) of the teeth of the workpiece to the width (Bz) of the teeth of the gear-cutting tool is 2-20. Before and after each pass of the teeth of the gear-cutting tool through the tooth gaps of the workpiece, the thickness maximum of each tooth of the gear-cutting tool is positioned outside the gearing of the workpiece.

摘要： A planetary carrier includes a plurality of plate portions, and column portions connecting the plurality of plate portions. The column portions each have an outer circumferential surface, an inner circumferential surface, and sidewall surfaces. The sidewall surfaces are each formed in a circular arc shape and the circular arc shape has a center on an outer circumferential side in a cross section perpendicular to a shaft of the planetary carrier. An angle formed between the outer circumferential and each of the sidewall surfaces is an obtuse angle and an angle formed between the inner circumferential and each of the sidewall surfaces is an acute angle. The plurality of plate portions and the column portions are integrally formed as one sintered body.

摘要： A machining method for forming an opening through a workpiece, serving as a green compact, by moving a milling tool in a radial direction relative to the workpiece is provided. The milling tool includes a first milling tool and a second milling tool. The method includes a pre-machining step of using the first milling tool, and forming the first sidewall surface by rotating the first milling tool so as to cause cutting edges of the first milling tool to cut the workpiece from the acute angle corner to the obtuse angle corner, while leaving a cutting allowance on the second sidewall surface; and a post-machining step of using the second milling tool whose cutting edges are reversed from the cutting edges of the first milling tool, and forming the second sidewall surface by rotating the second milling tool so as to cause the cutting edges of the second milling tool to cut the cutting allowance from the acute angle corner to the obtuse angle corner.

摘要： A machine tool that generates internal teeth or external teeth on a cylindrical workpiece includes a workpiece holder, a column which is relatively movable to the workpiece holder, a rotary main spindle which is rotatable with respect to the column, a working tool which is held by the rotary main spindle, and a phase detecting unit which detects a phase of the working tool with respect to the rotary main spindle. The working tool includes a cutter portion which has cutters, a holder portion, and a detected portion which is formed on the holder portion. The phase detecting unit includes a detecting section which detects the detected portion, and a calculating section which calculates a phase angle of the detected portion with respect to a reference position of the rotary main spindle, based on a result detected by the detecting section.

摘要： The present application discloses a method for calibrating a measuring probe in a gear cutting machine by using a workpiece received in a workpiece holder of the gear cutting machine, wherein the measuring probe includes a measuring probe tip which is movably arranged on a measuring probe base, wherein the deflection of the measuring probe tip relative the measuring probe base can be determined via at least one sensor of the measuring probe, and wherein the measuring probe is traversable relative to the workpiece holder via at least two axes of movement of the gear cutting machine. The method comprises rotating the workpiece via an axis of rotation of the workpiece holder and traversing the measuring probe via the at least two axes of movement of the gear cutting machine such that in the case of a perfect calibration the touch point of the measuring probe tip on the tooth flank would remain unchanged.

摘要： For the precision machining of a workpiece (10) provided with gearing (11) and rotating about a rotation axis (Dw), teeth (3) of a gear-cutting tool (1) rotating about a rotation axis (Dz) are brought into engagement with teeth (12) of the workpiece (10), and the gear-cutting tool (1) and the workpiece (10) are moved relative to each other in a direction (AX+, AX−) parallel to the rotation axis (Dw). The thickness (dZ) of the teeth (3) of the gear-cutting tool (1) increases in the axial direction, starting from the respective front ends (4, 5) of the teeth, until a thickness maximum (dZmax) is reached. High material removal performances and long-term durability of the gear-cutting tool (1) are achieved in that, according to the invention, 2≤Bw/Bz≤20 applies (wherein Bw=width Bw of the teeth of the gearing (11) of the workpiece (10), Bz=width of the teeth (3) of the gear-cutting tool (1)), that the gear-cutting tool (1), before each pass of its teeth (3) through the tooth gaps (17) of the workpiece (10) in the respective axial directions (AX+, AX−), is positioned at a position (P1, P2) in which the thickness maximum (dZmax) of the teeth (3) of the gear-cutting tool (1) is situated outside the gearing (11) of the workpiece (10), and that as a consequence of the relative movement of the workpiece (10) and of the gear-cutting tool (1) in the axial direction (AX+, AX−), the teeth (3) of the gear-cutting tool (1) are each moved through the respective tooth gaps (17) of the gearing (11) of the workpiece (10) that are assigned to them, until the thickness maximum (dZmax) of each tooth (3) has exited the assigned tooth gap (17).

摘要： A method for manufacturing a rack bar includes joining axial end portions of first and second bar members to each other, and forming a power transmission section on the second bar member. The first bar member has a toothed portion. When the second bar member is hollow, the method may further include thickening a wall of a portion of the second bar member along the axial direction so as to be coaxial with the first bar member. When the second bar member has a greater diameter than the first bar member, the method may further include cutting an outside diameter of a portion of the second bar member in the axial direction so as to be coaxial with the first bar member. The power transmission section is formed on the portion of the second bar member where the wall has been thickened and/or the outside diameter has been cut.

摘要： A method wherein a cutting or grinding chamfering tool (25) is guided along the face width of a gear (12, 23, 52) through one tooth slot (8) (e.g. from heel to toe) while it contacts the topland corners (10, 1 1) of the respective concave and convex tooth flanks of adjacent teeth (2, 4). The tool moves to an index position, the gear is indexed to the next tooth slot position and the tool moves through the tooth slot (e.g. from the toe to the heel). The cycle is repeated until all topland corners are chamfered.
