Abstract
An annular retaining groove is formed on the inner circumferential portion of the disk-shaped rotating tool, and a ringlike cushioning member is fitted in this annular retaining groove so as to be partially exposed. Both sides of the inner circumferential portion of the disk-shaped rotating tool are held by first and second holding members through the annular cushioning member. An axial portion of the first holding member is engaged with an output shaft of an electric rotary machine so that the disk-shaped rotating tool is rotated through the first holding member by the output shaft.
Claims4
A device for mounting a disk-shaped rotating tool having a grinding surface on the outer circumferential portion thereof to an output shaft of an electric rotary machine, the inner circumferential portion of said disk-shaped rotating tool having a first annular retaining groove formed on at least a surface opposed to said electric rotary machine, said device comprising:
- a first ringlike cushioning member fitted in said first annular retaining groove;
- a first holding member provided on one side of said disk-shaped rotating tool and fixed to said output shaft of said electric rotary machine;
- and
- a second holding member fixed to said first holding member so as to come into pressure contact with said first ringlike cushioning member from the other side of said disk-shaped rotating tool, thereby holding said disk-shaped rotating tool in cooperation with said first holding member.
