Abstract
PURPOSE:To prevent the abrasion of a washer and the seizure of an oilless bearing from being generated, by contriving the washer not to come in direct contact with the upper end surface of the oilless bearing. CONSTITUTION:One section of a rotary shaft 1 rotated vertically in one direction is provided with the step section 2 of a diameter larger than that of the shaft 1, and on the lower side of the step section 2, the washer 4 of an outer diameter equal to the outer diameter of a cylindrical oilless bearing 3 made of sintered oilless alloy sliding together with said rotary shaft 1 is pushed against the plane of the step section 2, and is fixed. Then, on a sliding section 5 sliding together with the oilless bearing 3 on the lower side, a plurality of different inclination grooves 6 inclined to a lower section in the rotational axis direction are formed. The washer 4 is composed to come in contact with the upper end surface 7 of the oilless bearing 3 with the tare weight of the rotary shaft at the time of stopping rotation. When the rotary shaft 1 is rotated, then the oil of the oilless bearing 3 included in the inclination grooves 6 is pushed toward an upper section by a centrifugal force, and an oil film is formed between the upper end surface 7 of the oilless bearing 3 and the washer 4.
