Description

Technical Field

[0001] The utility model relates to the technical field of turbochargers, in particular to a low-imbalance turbocharger core structure. Background Art

[0002] The core support components of the movement in the turbocharger are usually made of high-strength alloy steel with good rigidity and fatigue resistance. The turbine shaft is connected to the turbine impeller at one end and the compressor impeller at the other end. Its length and diameter are designed according to the specific model and performance requirements of the turbocharger. In high-performance turbochargers, the turbine shaft may be relatively long and have a larger diameter to adapt to higher speeds and torque transmission. In the processing of the turbine shaft, it is necessary to ensure that its cylindricity, straightness and surface roughness meet high-precision requirements. The turbine shaft is processed using precision grinders and lathes to control its diameter tolerance at the micron level and the straightness error is less than a certain allowable range. This can reduce the vibration and imbalance of the shaft during rotation.

[0003] After searching, the Chinese patent announcement number: CN218934558U discloses a fixing structure for a turbocharger movement, including: a shock-absorbing support, an elastic sleeve and an energy absorbing component. The surface of the shock-absorbing support is provided with a placement groove, the elastic sleeve is fixedly installed on both sides of the shock-absorbing support, and the energy absorbing component is fixedly installed on one side of the elastic sleeve. The elastic sleeve includes a swing ring, a fixing ear, and a first connecting bar and a second connecting bar for connecting the swing ring and the fixing ear. The first connecting bar and the second connecting bar are vertically connected to each other, and the energy absorbing component includes a swing frame and a positioning truss respectively fixed to the surface of the swing ring and the fixing ear. In the utility model, a novel shock-absorbing support structure is provided, and the structural elasticity of the shock-absorbing support and the energy-absorbing component is utilized to elastically support the turbocharger movement, and the movement sleeve is sleeved on both ends of the turbocharger movement and fixed on the surfaces of the energy-absorbing component and the elastic sleeve, so as to avoid damage to the turbocharger movement caused by external vibration during transportation and handling. Although the above structure achieves a protective effect during transportation, it does not take into account a good disassembly and assembly effect when installing the turbocharger movement, which results in a large amount of time being consumed during the disassembly and assembly process, thereby reducing the disassembly and assembly efficiency and being inconvenient for operators to use.

These protective strips 3 not only play a protective role, but also a long rod 8 is provided in the middle part of the front side of the front housing 9.

[0037] Working principle: When it is necessary to use the turbocharger core, first install the front housing 9 on the front side of the turbocharger 1, and then rotate one end of the rotating rod 10 against the rear side of the front housing 9. After that, slide the rotating piece 18 outward along the outer wall of the rotating rod 10. By threading the front housing 9 with the corresponding screw 16, it is ensured that the rotating piece 18 cannot move. At this time, pick up the limiting plate 17 and snap it onto the outer wall of the rotating rod 10. Then pick up the turbine blade 14 and fit it onto the limiting plate 17. Then twist the limiting column 15 along the outer wall of the screw 16 to effectively limit the turbine blade 14. In this way, the core on the turbocharger can be quickly disassembled and assembled in a short time, saving a lot of time and improving the installation efficiency;

[0038] After that, connect the turbocharger 1 with the hollow pipe 203 and communicate with the connecting column 206.

At this time, twist the bolt one 208 to make the two long blocks 207 gather relative to each other, and finally tighten the steel bar 204 to cooperate with the immobility of the connecting pipe 201. In this way, the air outlet pipe on the turbocharger can be quickly disassembled and installed, ensuring the normal operation of the turbocharger and improving the use efficiency of the device.
