    摘要： The hoist machine includes the main shaft 10 having its one axial end attached to the casing 7 via a bearing 11, and the other end to which another bearing 12 is attached. The bearing 12 attached to the other end of the main shaft is disposed inside the housing 13. The housing 13 is located closer to the casing than the support base 14, and fixed thereto with a bolt 15. The friction force is generated between the housing 13 and the support base 14 under the axial force caused by fastening the bolt 15 to fix the housing 13 and the support base 14 so as to bear the suspension load.

    摘要： An oil-lubricated bearing assembly (10) for supporting a rotating shaft (12) with respect to a support member (14), comprises a tubular housing body (16) which surrounds an axial through cavity (24). The housing body has an annular bearing seat (26) facing radially inwards within the through cavity (24). A bearing (18) is received in the through cavity (24) of the housing body (16), with at least one outer race ring (28) fitted into the bearing seat (26). A sealed inner space (56) including the bearing is defined between two annular seal assemblies (36, 52). A mounting flange (72) integral with the housing body (16) protrudes radially from the housing body (16). The mounting flange (72) is provided with axial through holes (74) extending in the axial direction for fixing the housing body (16) to a wall (14) of the support member, which extends perpendicularly to the reference axis.

    摘要： An outer ring (31) has a small-diameter stepped part (37) comprising a stepped part outer peripheral surface (37a) and a step-difference surface (37b), and a locking groove (37c) is formed in the stepped part outer peripheral surface (37a). The inner peripheral surface of a fixing plate (40) is provided with a small-diameter hole part (41) facing the stepped part outer peripheral surface (37a), and a large-diameter hole part (42) facing the outer peripheral surface (31a) of the outer ring (31) and guiding a rolling bearing (30). The fixing plate (40) is provided with a plurality of locking pawls (49) for locking into the locking groove (37c), the locking pawls protruding diametrically inward from the inner periphery of the small-diameter hole part (41), and the fixing plate (40) and the rolling bearing (30) are inseparably assembled by locking the locking pawls (49) into the locking groove (37c).
