Title:
METHOD FOR GRINDING TAPERED ROLLER
Document Type and Number:
Japanese Patent JP3871015
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a method for grinding a tapered roller with countermeasures taken against a diverging phenomenon called, 'jarring', by analyzing it to find the principle of its occurrence, and thus to achieve highly efficient and stable grinding.
SOLUTION: The tapered roller 9 is inserted between a grinding wheel 11 and an adjustment wheel 5. The wheel 5 is disposed opposite to the wheel 11 and has a thread-like groove. At least a part of an outer circumferential surface of the roller 9 makes contact with a bottom surface of the groove of the wheel 5. The roller 9 is supported by a blade 7 while it is regulated not to rise by a top blade 13. When the outer circumferential surface of the roller 9 is ground by centerless throughfeed, the smaller diameter side of the roller 9 comes up to a height regulated by the top blade 13 and the wheel 5. In this state, when an inclination angle θw of the center line of the roller is made so that the larger diameter side of the roller 9 is higher than the smaller diameter side thereof, a throughfeed angle θth made by the axis of rotation of the wheel 5 with the througfeed direction is set to satisfy θth≥θw.
