Abstract

The invention relates to a powder metallurgy wear-resistant automobile bearing, which is obtained by mixing the following components in parts by weight uniformly, and then mixing and molding-sintering, specifically Cu powder: 2-3 parts, Fe powder: 82-95 parts Parts, Al powder: 1-2 parts, W powder: 2-5 parts, V powder 0.6-1.5 parts, tetrabutyl titanate and titanium tetrachloride in the mixed solution of tetrabutyl titanate and titanium tetrachloride Total parts: 3-5 parts, colloidal graphite in colloidal graphite solution: 2-4 parts and Mo powder: 3-5 parts; Wherein, the mixing of described colloidal graphite solution and tetrabutyl titanate and titanium tetrachloride After the solution is mixed, it is added dropwise to the above-mentioned pre-activated alloy powder after grinding, and mixed evenly. The present invention uses colloidal graphite and titanium source precursors to prepare a mixture of graphite and titanium dioxide, then generates TiN powder at high temperature under the reduction of Al powder, and distributes it very uniformly in the alloy powder, effectively improving the wear resistance and wear resistance of automobile bearings. Heat resistance.

Description

technical field [0001] The invention belongs to the field of powder metallurgy, and in particular relates to a powder metallurgy wear-resistant automobile bearing and a preparation method thereof. Background technique [0002] The main function of the bearing (hub bearing) is to bear weight and provide precise guidance for the rotation of the hub. It bears both axial load and radial load, and is a very important component. [0003] The bearing has two main functions: one is to keep the shock absorber rotating with the wheel when the vehicle is turning, so as to maintain the flexibility of steering; The flexible connection prevents the vibration from being transmitted to the body through the shock absorber due to uneven road surface when the car is running. [0004] Although the automobile bearing is a small part, it is closely related to the reliability, safety and comfort of the whole vehicle. Bearings have an important impact on the performance of the vehicle. In terms o...
