Definitions

  • the present invention relates to, for example, a turbine rotor that is used in a turbocharger for a motor vehicle to eliminate residual stress at the time of manufacture and to prevent axial centering of the rotor shaft during operation.
  • a turbine wheel made of a heat-resistant material and a rotor shaft that does not need to use a heat-resistant material in particular are different materials because the turbine wheel needs heat resistance.
  • the two are separately manufactured by using an electron beam welding etc. That is, as shown in FIG. 5, in the conventional turbine rotor 100, the electron beam E is applied in the direction perpendicular to the axial direction to the joint surface 106 of the turbine wheel 102 and the rotor shaft 104, and both are rotated. Is to be welded all around.
  • Patent Documents 1 and 2 disclose a method of welding a turbine wheel and a rotor shaft using an electron beam.
  • the welding method disclosed in Patent Document 1 is a method of connecting a turbine wheel formed of a heat-resistant metal and a rotor shaft, and rotating the turbine wheel and the rotor shaft while bonding them, and an electron beam at the bonding portion Irradiate and weld. Thereafter, the electron beam is irradiated while scanning a predetermined width toward the rotor shaft side from the bonding portion, and the rotor shaft in the vicinity of the bonding portion hardened by the thermal effect at the time of welding is tempered.
  • Patent Document 1 performs welding by irradiating the electron beam to the joint and welding it, and then irradiating it while scanning the electron beam in the vicinity of the axial side of the joint hardened due to heat effect. Therefore, it aims at what is called a production technical solution which becomes possible to carry out welding processing continuously, and does not aim at elimination of the fall of a rotor shaft.
  • Patent Document 1 only by tempering the rotor shaft side region, the falling of the rotor shaft is not eliminated. For this reason, if the rotor shaft after welding falls, the yield of the turbine rotor decreases. In addition, in order to correct the shaft center collapse by machining, two processes of a welding process and a machining process are required, and the productivity of the turbine rotor is greatly reduced. On the other hand, although the welding method of Patent Document 2 seems to be effective in suppressing residual stress that is biased in the circumferential direction, it requires a plurality of electron beam devices, resulting in a problem of high cost.
  • the present invention is a low-cost device that suppresses the collapse of the rotor shaft after welding to improve the yield and improve the productivity of the turbine rotor to enable mass production.
  • the purpose is to realize a rotor.
  • the present invention relates to a turbine rotor in which a turbine wheel made of a heat resistant metal and a rotor shaft made of carbon steel are connected by butt welding,
  • the turbine wheel and the rotor shaft have a structure formed by irradiating and welding a heat generating beam from a heat generating beam generator to a junction thereof, Local angle distribution of the rotor shaft generated at the time of welding by irradiating the electromagnetic energy or thermal energy adjusted to a fixed amount from the energy generator while scanning the rotor shaft side including the butt welding position of the joint with a predetermined width Temper to generate the residual stress of the entire circumference, and the axial center inclination generated around the outer periphery of the turbine wheel is suppressed to 0.2 mm or less during operation of the turbine rotor.
  • the energy generator used for the tempering may be a high frequency induction heater or a laser beam generator, and more preferably, the heat generating beam generator used for welding is a laser beam or electron beam generator. Is good.
  • the material of the rotor shaft is made of carbon steel which has a relatively high heat conductivity and a large heat capacity with respect to a turbine wheel made of a heat resistant metal.
  • the amount of thermal expansion or thermal contraction of the rotor shaft due to tempering after welding is made relatively large compared to the turbine wheel. Therefore, residual stress over the entire circumference can be generated in the welded portion in tempering to be described later.
  • the turbine wheel and the rotor shaft have a structure formed by irradiating and welding a laser beam or an electron beam (hereinafter referred to as a heat generation beam) to the joint portion.
  • a heat generation beam (for example, a high frequency induction heating device or a laser beam) composed of electromagnetic energy or thermal energy adjusted to a fixed amount from the energy generator while scanning the rotor shaft side including the butt welding position of the joint with a predetermined width ), And tempering is performed so that the residual stress of the local angular distribution of the rotor shaft generated at the time of welding is generated over the entire circumference.
  • the turbine rotor thus tempered is in a state in which residual stresses are balanced in the circumferential direction, and the equilibrium state is maintained even after cooling. Therefore, the rotor shaft does not fall and does not occur even if it is heated during operation. That is, at the time of operation of the turbine rotor, the axial center collapse ⁇ generated on the outer periphery of the turbine wheel can be suppressed to 0.2 mm or less. By setting the axial center inclination ⁇ to 0.2 mm or less, it is possible to suppress the occurrence of substantial noise and shaft vibration during operation to an allowable range.
  • tempering can be completed by one scan, and tempering work can be performed in a short time. Therefore, it is suitable for mass production of a turbine rotor.
  • the present inventors have found from various experiments that when welding the joint surface in the circumferential direction, local stress remains in the welding end side angular region. The reason is that the thermal expansion of the rotor shaft is larger than that of the turbine wheel, so that during welding the thermal expansion of the rotor shaft in the vicinity of the weld causes a tensile force to be applied to the weld. It is considered that the greatest tensile force acts because it is exposed to the longest time.
  • tempering of the turbine rotor it is preferable to carry out a large number of tempering treatments in the region excluding the end side angular region (region of about 0 to 90 °). For example, after welding one turn (360 °) or two turns (720 °) of the joint surface, the output is gradually reduced while rotating about a half turn (180 °), and the rotor shaft side area including the weld portion When tempering is performed for one turn or two turns, it is preferable to omit the end angle area of the tempering within the range of 270 to 360 °. As a result, since the rotor shaft expands in a region other than the end side region, residual stress is generated in the cooled weld portion, and therefore, residual stress can be generated uniformly over the entire circumference of the rotor shaft.
  • a high frequency heating device or a laser beam generator may be used.
  • the high-frequency heating device can be reduced in size and weight, and can generate power with high efficiency, so power can be saved and cost can be reduced.
  • rapid heating to a high temperature is possible, which is suitable for mass production.
  • the laser beam generator can obtain high power density, little heat input, little thermal influence on the peripheral part, and can control the irradiation position of the beam accurately.
  • unlike the electron beam there is no need to hold the periphery of the weld in a vacuum. Therefore, cost can be reduced and it is suitable for mass production.
  • the turbine rotor according to the present invention tempers the rotor shaft side area near the weld including the weld after welding between the turbine wheel and the rotor shaft, and the residual stress of the local angle distribution of the rotor shaft generated at the welding is all around Since generation is carried out over the entire area, it is possible to suppress the falling of the rotor shaft after cooling or in the subsequent operation. Therefore, it is possible to manufacture a turbine rotor at low cost without causing the rotor shaft to tilt. In addition, since correction work by machining after welding becomes unnecessary, the yield can be improved, and the manufacturing time can be shortened, which is suitable for mass production.
