Title: **Takaji Hattori: A Pioneer in the Field of Spherical Bearings**
Introduction
Takaji Hattori, an innovative inventor based in Hamamatsu, Japan, has made significant contributions to the engineering sector through his patented inventions. With two patents to his name, Hattori has developed technologies that enhance the functionality and durability of mechanical components.
Latest Patents
Hattori's most recent patents include the **Spherical Slide Bearing** and the **Ball Joint**. The Spherical Slide Bearing features dust covers that are secured by outer sealing collar portions, which are strategically placed between the housing and the bearing. This design prevents interference with angular movement while protecting the dust covers from damage. Additionally, tapered motion-limiting surfaces in the components provide an increased range of angular movement, ensuring the assembly's reliability.
The Ball Joint, another noteworthy invention, comprises a pair of hemispheric head members with a bearing member situated between their facing surfaces. One head member is connected to a ball stud, while the other features a shank hole that accommodates the ball stud. This assembly is enclosed in a conforming ball seat that effectively complements the spherical outer surfaces of the heads. An elastic member applies axial force to maintain preloading, which helps in accommodating wear during its operation.
