Title: Keqiang Cao: Innovator in Bearing Technology

Introduction

Keqiang Cao is a prominent inventor based in Shanghai, China, known for his contributions to bearing technology. With a total of three patents to his name, he has made significant advancements in methods and devices for structural fatigue life testing of bearings.

Latest Patents

Cao's latest patents include a method and device for structural fatigue life testing of bearings. This innovative method involves a cam embedded in the bearing under test, which generates a rotational dynamic radial expansion. This expansion is transmitted through the bearing to a load collar, compactly mounted on the periphery of the bearing. The design allows for the application of a rotational dynamic strain pressure load, primarily in the radial direction, to the bearing. Additionally, he has developed a bearing seal that includes an anchoring portion fixed on the inner ring of the bearing and a sealing portion that forms a sealing fit with the outer ring. This seal provides a rigid slinger of substantially circular shape, enhancing the stability and support of the bearing.
