Definitions
- the present invention relates to a compressor and a turbocharger used for an internal combustion engine.
- a conventionally-used turbocharger for compressing air to be supplied to an internal combustion engine is equipped with a compressor including an impeller for compressing air, an air-guide cylinder for housing the impeller and guiding the air, and a scroll-chamber frame disposed adjacent to the air-guide cylinder, the scroll-chamber frame forming a scroll chamber for guiding the air having passed through the air-guide cylinder to outside.
- the turbocharger described in Patent Document 1 includes a shock-absorbing partition wall disposed between a diffuser of a compressor and a head tank storing lubricant oil for lubricating a journal bearing so as to prevent the head tank from breaking apart to bring about oil leakage when a part of the impeller bursts and scatters outwardly.
- Patent Document 1 JP2001-132465A
- an impeller fragment may fly off outwardly in the radial direction of the impeller, and may hit the air-guide cylinder and a frame around the air-guide cylinder, for instance. If the impeller fragment hits the air-guide cylinder or a frame around the air-guide cylinder, for instance, there is a risk of generation of tensile stress in a bolt for fastening a scroll-chamber frame adjacent to the air-guide cylinder and a frame adjacent to the scroll-chamber frame, which may break the bolt.
- Patent Document 1 describes a configuration for preventing breakage of a lubricant-oil head tank upon scatter of an impeller described above, it does not disclose breakage of the bolt due to scatter of the impeller or a solution thereto.
- An object of some embodiments of the present invention is to provide a compressor and a turbocharger whereby it is possible to suppress breakage of a bolt that fastens a frame adjacent to a scroll-chamber frame and the scroll-chamber frame effectively, and to achieve a stable joint state between the frames.
- turbocharger With the turbocharger according to some embodiments of the present invention, it is possible to suppress breakage of the first bolt effectively even if tensile stress is generated due to breakage of the impeller.
- FIG. 1 is a schematic diagram illustrating an overall configuration of an internal combustion engine system 100 according to some embodiments.
- the internal combustion engine system 100 illustrated in FIG. 1 includes an internal combustion engine 2, a turbocharger 4 for pressurizing intake air sucked into the internal combustion engine 2, and a generator 8 driven by a turbine 6 of the turbocharger 4.
- the turbocharger 4 illustrated in FIG. 1 includes a compressor 10 of centrifugal type for pressurizing intake air sucked into the internal combustion engine 2, a turbine 6 coupled to the compressor 10 via a rotation shaft 12 and driven by exhaust gas of the internal combustion engine 2, and a silencer 13 for reducing noise that the compressor 10 generates.
- the turbocharger 4 illustrated in FIG 1 is a supercharger of exhaust-turbine drive type, which is called a turbocharger, in which the compressor 10 is driven by the turbine 6 driven by exhaust gas of the internal combustion engine 2.
- the turbocharger 4 may be a supercharger of mechanical drive type, which is called a supercharger, in which the compressor 10 is driven by power extracted from an output shaft of the internal combustion engine 2 via a belt or the like.
- a diesel engine or a gasoline engine may be suitably selected as the internal combustion engine 2 for instance.
- FIG. 2 is a schematic cross-sectional view of a part of a turbocharger 4 according to some embodiments.
- the compressor 10 illustrated in FIG 2 includes an impeller 14 for compressing air, an air-guide cylinder 16 housing the impeller 14 and guiding air, a scroll-chamber frame 20, and a bearing frame 40.
- the impeller 14 includes a hub 15 and a plurality of blades 17 disposed around the hub 15.
- the scroll-chamber frame 20 is disposed adjacent to the air-guide cylinder 16, and includes a scroll-chamber forming portion 19 which forms a scroll chamber 18 for guiding air that has passed through the air-guide cylinder 16 to outside.
- the bearing frame 40 includes a bearing portion 44 for pivotably supporting a rotation shaft 12 of the impeller 14.
- the silencer 13 includes a silencer frame 22 disposed adjacent to the scroll-chamber frame 20.
- a flange portion 23 of the scroll-chamber frame 20 and a flange portion 24 of the silencer frame 22 are fastened to each other by a bolt 25.
- a spacer 28 (see FIG. 3 ) is disposed between a head portion 26 of the bolt 25 and the scroll-chamber frame 20.
- a flange portion 46 of the bearing frame 40 and a flange portion 29 of the scroll-chamber frame 20 are fastened to each other by a bolt 48.
- an impeller fragment may fly apart outwardly in the radial direction of the impeller 14, and may hit the air-guide cylinder 16, the scroll-chamber frame 20, or the like.
- the hit causes an inlet 32 of the air-guide cylinder 16 to move toward the silencer 13 in the direction S of the arrow (see FIG. 3 ) and hit an outlet 43 of the silencer frame 22.
- the flange portion 24 of the silencer frame 22 tries to move away from the flange portion 23 of the scroll-chamber frame 20, which leads to generation of tensile stress on the bolt 25.
- the compressor 10 and the turbocharger 4 are configured such that the spacer 28 is disposed between the head portion 26 of the bolt 25 and the scroll-chamber frame 20, which makes it possible to fasten the scroll-chamber frame 20 and the silencer frame 22 using the bolt 25 with a shank portion 31 (see FIG. 3 ) having a large length (shank length) as compared to a case where the spacer 28 is not provided.
- a shank portion 31 see FIG. 3
- the spacer 28 illustrated in FIG. 3 is formed in a sleeve shape and disposed so as to surround the shank portion 31 of the bolt 25, and the inside diameter d 1 of the spacer 28 is smaller than the diameter d 2 of the head portion 26 of the bolt 25.
- the dimension d 3 of the spacer 28 in the axial direction of the bolt 25 illustrated in FIG. 3 is greater than the dimension d 4 of the spacer 28 in the radial direction of the spacer 28.
- FIG 3 an example in which tensile stress is generated due to breakage of the impeller 14 on the bolt 25 fastening the scroll-chamber frame 20 and the silencer frame 22 is described.
- tensile stress may be generated due to breakage of the impeller 14 on the bolt 48 fastening the scroll-chamber frame 20 and the bearing frame 40.
- the impeller fragment enters a diffuser portion 50 illustrated in FIG. 2 and gets stuck in the diffuser portion 50, the impeller fragment presses the diffuser portion 50 to expand in the axial direction of the impeller 14.
- the scroll-chamber frame 20 and the bearing frame receive a force in a direction away from each other, and thus the scroll-chamber frame 20 deforms as illustrated in FIG. 4 and tensile stress is generated on the bolt 48.
- the spacer 28 described with reference to FIG 3 may be disposed between the head portion 52 of the bolt 48 and the scroll-chamber frame 20 to make the shank portion 53 of the bolt 48 longer than that illustrated in FIG. 4 .
- the flange portion 29 of the scroll-chamber frame 20 is disposed so as to extend outwardly from the scroll-chamber forming portion 19 in the radial direction of the impeller 14.
- the turbocharger 4 and the compressor 10 illustrated in FIG. 2 includes a clamp 54 configured to nip the scroll-chamber frame 20 and the bearing frame 40 as illustrated in FIGs. 5 and 6 .
- FIG. 5 is a view of the flange portion 29 of the scroll-chamber frame 20 and the flange portion 46 of the bearing frame 40 as seen from direction P in FIG 2 , illustrating the arrangement of the bolt 48 and the clamp 54.
- FIG. 6 is a schematic cross-sectional view for describing a structure of the clamp 54.
- the clamp 54 illustrated in FIGs. 5 and 6 includes a pressing bolt 56 that applies a pressing force to the bearing frame 40 from the opposite side from the flange portion 29 of the scroll-chamber frame 20.
- a pressing bolt 56 that applies a pressing force to the bearing frame 40 from the opposite side from the bearing frame 40.
- the clamp 54 is configured to nip the scroll-chamber frame 20 and the bearing frame 40.
- a clamp configured to nip the scroll-chamber frame 20 and the silencer frame 22 may be used. In this way, it is possible to join the scroll-chamber frame 20 and the silencer frame 22 stably.
