TH97115A - Fluid bearing device - Google Patents

Abstract

DC60 overhang (7b3), directed downward along the axis, is provided. At the bottom (7b) of the housing (7) and the outer periphery (7b31) of the protrusions (7b3), they are fixed to the inner surrounding (6a) of the mounting bracket (6. ) When causing a shock load Executed against the bottom (7b) of the housing (7), the part of the load is supported by the mounting bracket (6) through the overhang (7b3), thus providing the resistance of the edge (P). Between the side (7a) and the bottom (7b) of the case (7) increase, which makes it possible to block Fragmentation (P) due to excess load In other words Can make The wall thickness of the butt (7b) unchanged. Therefore it is possible to restrict the force. Deformation through casting shrinkage of the bearing surface which forms on the surface at the inner end (7b1) of the butt (7b) overhang (7b3) directed downward. At the bottom, the axes are provided. At the bottom (7b) of the housing (7) and the outer periphery (7b31) of the protrusions (7b3), they are fixed to the inner surrounding (6a) of the mounting bracket (6. ) When causing a shock load Executed against the bottom (7b) of the housing (7), the part of the load is supported by the mounting bracket (6) through the overhang (7b3), thus providing the resistance of the edge (P). Between the side (7a) and the bottom (7b) of the case (7) increase, which makes it possible to block Fringe fracture (P) due to excess load on the other hand can cause The wall thickness of the butt (7b) unchanged. Therefore it is possible to restrict the force. Deformation through casting shrinkage of the bearing surface which forms on the surface at the inner end (7b1) of the butt (7b).

Claims (4)

1. The flow bearing device, which consists of: a housing which has the side sections and the bottom which are assembled together and where the side sections are. An opening at one end that has been closed on the outer casing with a bottom part; Axial assembly, housed in the housing; Radial bearing gap facing the outer surrounding surface of the axial assembly; And the bearing gap, which faces the surface at the inner end of the bottom of the housing. Where the bottom of the case consists of the outer periphery of the end surface. Outside there, with protrusions that are axially and exited from the opening and where the protrusions are fixed to the inner surrounding surface of the mounting bracket. 2. Equipment bearing with fluid according to claim 1, where the overhang has a radial wall thickness. Which is larger than the wall thickness of the side part of the case 3. Equipment bearing with fluid according to claim 1, where the submission consists of Section for reinforcement, which increases the radial wall thickness when The reinforcement section extends to the surface at the outer end of the case bottom. 4. Equipment bearing with fluid according to one of the claims 1 to 3 Included Further, the U-shaped recess is provided at the edge between the inner surface of the The side of the case and the surface at the inner end of the butt
