Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0019] Such as figure 1 and figure 2 Commonly shown, the present invention first proposes a floating bearing, which firstly includes a cylindrical bearing body 1, the outer diameters of the two ends of the bearing body 1 are larger than the outer diameter of the middle part, that is, the overall shape is dumbbell shape.

[0020] There are lubricating oil holes 2 through the side wall of the bearing body 1. In this embodiment, two lubricating oil holes 2 are ope...

Abstract

The invention provides a floating bearing and a turbocharger of an internal combustion engine adopting the floating bearing, and aims to solve the problem of influence on normal operation of the turbocharger of the internal combustion engine caused by low abrasion resistance, high oil consumption and short service life of the floating bearing in the prior art. The floating bearing comprises a cylindrical bearing body, wherein the bearing body is made of a zirconia ceramic material; a lubricating oil hole which penetrates through the side wall of the bearing body is formed in the middle of the bearing body. The turbocharger of the internal combustion engine comprises an intermediate and the floating bearing, wherein an inner cavity is formed in the intermediate; a turbine shaft which rotates by taking self-axis as the center is arranged in the inner cavity of the intermediate; the floating bearing is positioned in an interval between the intermediate and the turbine shaft; an outer lubricating oil film is formed between the intermediate and the floating bearing; an inner lubricating oil film is formed between the floating bearing and the turbine shaft. The working performance of the turbocharger of the internal combustion engine can be effectively improved according to the characteristics of the floating bearing which is made of the zirconia ceramic material, and the service life of the turbocharger is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a floating bearing and an internal combustion engine turbocharger using the floating bearing. Background technique [0002] The turbocharger is a device that uses the exhaust energy of the internal combustion engine to drive the turbine and drive the compressor to increase the intake pressure of the internal combustion engine. Among them, the floating bearing is the supporting body of the rotor part of the turbocharger of the internal combustion engine. It not only bears the gravity of the rotor parts, the force of the gas on the rotor, the centrifugal force caused by the unbalanced mass of the rotor and the external load caused by the engine vibration, but also bears The heat load from the turbine end therefore requires good mechanical strength of the non-locating bearing. In addition, it must not only ensure the reliable operation of the rotor rotating at high speed, but also...
