Abstract:

A centrifugal abrasive grain projecting device comprising a cover main body (2) surrounding impeller (1), a cylindrical body (6) rotatably mounted on the external surface of a side wall of the cover main body, a control (7) passing through the cylindrical body so as to be inserted into the impeller and detachably affixed to the cylindrical body at one end thereof, an introducing tube (9) adapted to be in abutment with one end of the control gauge via an elastic member (8) having an annular distal end and detachably held between the control gauge and a holding mechanism (10), and a rotational driving mechanism (17) for reversibly rotating the cylindrical body, wherein a device is provided for preventing abrasive grains from entering a portion where the cover main body is fitted into the cylindrical body and stopping the rotation of the cylindrical body. In the device, the control gauge is rotatably mounted on the cylindrical body via a roll bearing (5), and a rolling body (5a) of the roll bearing is closed on the impeller side thereof with a liner (15) via a filler member (14), and on the introducing cylinder side thereof with a bearing cover (23) via a filler member (22).
