Machining tool for manufacturing radial bearings, and manufacturing apparatus and manufacturing method using the same |
摘要 |
A machining tool for manufacturing a radial bearing, and a manufacturing apparatus and a manufacturing method using the machining tool are provided. The machining tool includes an inner surface finishing tool to finish an inner circumference surface of a bearing hole provided on a radial bearing. The inner surface finishing tool includes a tool shaft main body member that defines a hollow storage section provided within the tool shaft main body member, a rotatable core piece member mounted inside the hollow storage section in a manner to be rotatable within the tool shaft main body member, and a plurality of roll machining members each with a circular cross-sectional roll machining surface. The plurality of roll machining members rollably abut against the outer circumference surface of the rotatable core piece member. The plurality of roll machining members are in contact under pressure with the inner circumference surface of the bearing hole. The rotatable core piece member is movable in the radial direction and can be tilted with respect to the central axis of the tool shaft main body member.
