Turbochargers generally comprise a turbine, an impeller and a transmission shaft for connecting the turbine and the impeller, and with increasing rotation speed of the turbocharger, common sliding bearings are difficult to be qualified, so most of turbochargers currently adopt floating bearings to support the transmission shaft, the floating bearings are generally of tubular structures and generally comprise full floating bearings (self-rotatable) and half floating bearings (self-fixed in bearing seats and non-rotatable), and in operation, both inner cylindrical surfaces and outer cylindrical surfaces of the floating bearings form dynamic oil films, so that elastic support is provided for the transmission shaft, damping is provided, and a damping effect is provided.
In the working state, lubricating oil enters between the inner wall of the bearing seat and the bearing through the oil duct and can enter between the inner wall of the bearing and the transmission shaft through the oil hole on the side wall of the bearing, and the transmission shaft is suspended and rotates at a high speed through the oil film, so that the oil film bears the load of a bearing system, but if the oil quantity is insufficient or the speed of the lubricating oil entering the bearing seat and the bearing is slower, the lubricating oil is easy to sinter due to overhigh temperature or form dry friction between the outer wall surface of the floating bearing and the inner wall surface of the bearing seat due to insufficient lubrication, and excessive energy is consumed, so that the low-speed performance and the acceleration effect of an engine can be greatly influenced, the damage to the turbocharger can be even caused, and even if the highest temperature of some imported bearing lubricating oil can reach more than 120 ℃, the turbocharger is still difficult to be qualified.

As shown in fig. 1-4, the power transmission structure of the leo triangle bearing type for the turbocharger comprises a bearing seat 1 and a transmission shaft 2 penetrating through the bearing seat 1, wherein the left end and the right end of the transmission shaft 2 extend out of a shaft hole 1a of the bearing seat 1 and are respectively provided with an impeller 3 and a turbine 4, an oil inlet channel 1b communicated with the shaft hole 1a is formed in the bearing seat 1, a floating bearing 5 is sleeved on the transmission shaft 2, the floating bearing 5 is positioned in the shaft hole 1a, two ends of the floating bearing 5 are respectively provided with a retainer ring 6 (or a limiting sleeve), the retainer ring 6 is fixedly arranged in the shaft hole 1 and is provided with a gap with the end face of the floating bearing 5, an oil groove 5a is annularly formed in the side wall face of the floating bearing 5, a plurality of oil holes 5b communicated with the inner cavity of the floating bearing 5 are formed in the bottom of the groove 5, and the profile of the cross section of the floating bearing 5 is in the shape of the leo triangle.
In the lyocell-type power transmission structure for a turbocharger provided in the above embodiment, the design of the floating bearing 5 may be applied to a full-floating bearing or a half-floating bearing (which may be applied to a rolling bearing of a structure form of being internally nested in a bearing housing in practice) of a turbocharger, and compared with a conventional bearing of which the cross-sectional profile is circular, the profile of the cross-section of the floating bearing 5 in the structure is in the form of a lyocell triangle, and the design may increase the size of the space between the outer wall surface of the floating bearing 5 and the inner wall surface of the shaft hole 1a, thereby increasing the volume of lubricating oil in the space, and the sufficient oil amount may prevent the lubricating oil from being easily sintered; moreover, the contact area between the floating bearing 5 and the inner wall surface of the shaft hole 1a is reduced in the rotating process, so that friction is effectively reduced, energy consumption in the running process is greatly reduced, and the performance of the engine can be well maintained; in addition, since the floating bearing 5 of the structure is eccentrically rotated during operation, the size of the space between any one of the outer wall surfaces and the inner wall surface of the shaft hole 1a is dynamically changed during the rotation, so that the lubricating oil in the shaft hole 1a can be extruded to a certain extent, and since the liquid cannot be compressed, part of the extruded lubricating oil can enter the inner cavity of the floating bearing 5 from the oil hole 5b more quickly, and the other part of the extruded lubricating oil can be discharged more quickly, so that a relative high-pressure area and a relative negative-pressure area can be formed, thereby promoting the rapid flow of the lubricating oil, increasing the lubricating performance and the cooling performance of the lubricating oil, further reducing the risk of sintering, providing better lubrication guarantee for the transmission shaft and improving the reliability of the Lai triangle bearing type power transmission structure for the turbocharger.
Preferably, the cross section of the inner wall of the shaft hole 1a may be circular as shown in fig. 3, or polygonal as shown in fig. 4, which may preferably be square. Because the profile of the cross section of the floating bearing 5 is in a Lailo triangle shape, the volume of the floating bearing 5 can be reduced, when the floating bearing 5 rotates in the shaft hole 1a, the axial locus of a rotor assembly formed by the transmission shaft 2, the impeller 3 and the turbine 4 also tends to be stable due to the stability of the structure of the triangle, and the larger locus deviation cannot be generated, so that the size of a gap between the impeller 3 and a volute of a compressor and the size of a gap between the turbine 4 and a turbine box cannot be influenced, the two gaps can be kept in a stable small range, and larger gas leakage loss caused by the gaps is avoided, so that the working capacity and the efficiency of the impeller 3 and the turbine 4 are kept stable, that is, compared with the existing circular bearing, the efficiency and the reliability of a turbocharger are not influenced by using the Lailo triangle-shaped floating bearing 5.
It should be noted that, the drawings in this specification are modified, and the gaps between the components in fig. 3-4 have been enlarged, so as to facilitate understanding and identification, and the gaps after assembly are not excessively large in practice.
More preferably, the plurality of oil holes 5b on the floating bearing 5 are arranged at the bottom of the oil groove 5a at uniform intervals in a ring shape, and by arranging the plurality of oil holes 5b at uniform intervals in a ring shape, the lubricating oil can more uniformly and sufficiently enter the inner cavity of the floating bearing 5.
More preferably, the number of the floating bearings 5 is two, and two floating bearings 5 are provided on the drive shaft 2 at intervals.
In addition, in this embodiment, the transmission shaft 2 is provided with a shaft shoulder, the transmission shaft 2 is sleeved with a thrust sleeve 7 and a sealing sleeve 8, the right end of the thrust sleeve 7 abuts against the shaft shoulder, the left end of the thrust sleeve abuts against the sealing sleeve 8, and the left end of the sealing sleeve 8 abuts against the impeller 3, so that the reliability of the Lailo triangle bearing type power transmission structure for the turbocharger is better.
