摘要： Based on a left tooth surface (28) having a maximum accumulated pitch error ALmax (when clockwise direction is a positive direction) and a right tooth surface (29) having a minimum accumulated pitch error ARmin (when clockwise direction is a positive direction), which are conceived to most likely have insufficiently ground portions, a correction value δθ which cancels these accumulated pitch errors for suppressing the accumulated pitch error after grinding is obtained. A reference tooth groove angle θ0 is corrected by the correction value δθ, thereby obtaining the meshing angle θ of the work gear. All teeth detection and signal processing in a short period of time is realized by using a displacement sensor and a high-speed meshing-dedicated circuit board.

摘要： The invention relates to a method and machine for the dressing of a grinding tool (1), which has at least one tooth-shaped profile (2) with a first flank (3) and an opposing second flank (4). A disk-shaped dressing tool (5) used for dressing of the grinding tool (2) has a first abrasive area (6) and a second abrasive area (7). To allow a faster and thus more economical dressing of the grinding tool, the first abrasive area (6) contacts the first flank (3) and the second abrasive area (7) contacts the second flank (4) simultaneously, and the disc-shaped dressing tool (5) and/or the grinding tool (1) are pivoted relatively to another around an axis (A) being arranged perpendicular to the axis of rotation (C) of the grinding tool (1), so that both flanks (3, 4) are dressed simultaneously.

摘要： Crown wheels (21) are ground on a grinding machine with the aid of a hobbing grinding disc (11) of ceramic material which is formed on the same grinding machine with the aid of a dressing crown wheel (13) with one or more teeth (14) provided with a dressing material such as diamond. The shape of said crown wheel tooth or teeth is in principle the same as the shape of the teeth of the crown wheel to be ground. The hobbing grinding disc (11) is mounted on the grinding wheel shaft (12) of the grinding machine both during its formation and during the grinding of the crown wheels, while the dressing crown wheel (13) or the crown wheel (21) to be ground is mounted on the workpiece holder (15) of the grinding machine. During the formation of the hobbing grinding disc (11) or the grinding of the crown wheels (21) the movements of the hobbing grinding disc relative to the tooth or teeth (14) of the dressing crown wheel (13) provided with a dressing material or the crown wheels (21) to be ground are in principle the same. The shape of the tooth or teeth (14) of the dressing crown wheel is consequently always transferred in the same way by means of the hobbing grinding disc to the teeth of the crown wheels to be ground. Crown wheels can be ground very accurately in this way.
