Provided are a rotating electrical machine and a method for manufacturing the rotating electrical machine, wherein the tapered surface of a plate-side tapered section and the tapered surface of a shaft-side tapered section are bonded with pressure by having forces operate between a plurality of plate-side protruding sections and a plurality of shaft-side protruding sections n the directions wherein the plate-side protruding sections and the shaft-side protruding sections are separated from each other. Thus, a ring core is fixed to a shaft.

Rotating electrical machine and method for manufacturing rotating electrical machine

A device for measuring tooth surface deviation includes a contact detector that measures the deviation at the tooth surface of a dresser with respect to a grinding tooth surface formed on a helical grinding tooth of a grinding tool when the grinding tool and a dresser toothed wheel are rotated synchronously in a state in which the grinding tooth surface and the dresser tooth surface of the dresser toothed wheel can be brought into contact, and detects contact between the grinding tooth surface and the dresser tooth surface; and a controller that changes the speed of rotation of the dresser toothed wheel in such a way that the detection result of the contact detector comes within the range of contact determination data, and also measures the amount by which the grinding tool and the dresser toothed wheel have been changed in one revolution of the dresser toothed wheel.

Apparatus and method for measuring tooth surface deviation, apparatus and method for forming grinding tool, and gear meshing method for gear grinding apparatus

A gear grinding tool, which includes a helical tooth with grinding faces on surfaces thereof, grinds tooth faces of a gear as a workpiece with the grinding faces. The grinding face includes a rough grinding face for performing a rough grinding process. The grinding face includes a rough grinding face for performing a rough grinding process, and the rough grinding face includes a forming line for performing a finishing process.
