Abstract:
A semi-completing method for grinding spiral bevel and hypoid gears comprising the steps of:a. providing a grinding machine including; a frame having a tool carriage movably mounted thereto, a grinding disk mounted for rotation to the tool carriage and having an inner and outer peripheral surface, and a workpiece carriage coupled to the frame adjacent to the tool carriage for movement relative thereto;b. providing a controller in communication with the grinding machine and having machine readable grinding data stored therein;c. rotatably mounting a workpiece on the workpiece carriage and simultaneously rotating the grinding disk and moving the tool and workpiece carriages relative to one another in response to the grinding data causing the inner peripheral surface of the grinding disk to engage the work piece;e. moving the tool and workpiece carriages relative to one another in response to the grinding data such that the inner peripheral surface of the grinding disk moves between a starting and a reversing point generating a convex gear tooth flank on the workpiece;f. adjusting at least one of the workpiece and grinding disk relative to the other in accordance with the grinding data, and moving the tool and workpiece carriages relative to one another from the reversing to the staring point, cutting a concave gear tooth flank on the workpiece; andg. indexing the workpiece relative to the grinding disk and repeating steps a-f until one of said hypoid and bevel gears is formed from the workpiece.
