Kobayashi-Matsuura Lab (JTEKT Innovative Fundamental Technology Joint Research Chair)
Machine-translated · View original
A lab that creates new machines and robots starting from machine elements such as gears.

AboutAbout the lab
Manufacturing built around innovative machine elements.
The Kobayashi-Matsuura Lab analyzes and designs machine elements such as gears, and studies the technology for manufacturing them.
As the JTEKT Innovative Fundamental Technology Joint Research Chair, the lab works on developing technologies for gears and other components used in automobiles and robots.
The lab also aims to develop robot systems built around new machine elements, as well as machines for fields that strengthen society, such as welfare, medicine, and disaster response.
Key terms
- Machine element
- A basic component, such as a gear, screw, or bearing, that is commonly used in many machines
- Meshing
- The contact between the teeth of gears, through which they transmit rotation and force to each other
- Ball screw
- A component that places steel balls between a screw shaft and a nut to convert rotation into smooth linear motion

The lab studies the analysis and design of machine elements, which are essential for developing machines such as automobiles and robots, as well as technologies for making new machine elements. It also works on technology development for automotive steering and for systems that carry objects in cooperation with people.
*Illustrative imageAnalysis and design of machine elements such as gears
The lab analyzes changes in meshing caused by gear deformation, wear of tooth surfaces, and the motion of steel balls inside ball screws. It is also developing theory for designing the tooth surfaces of new gear shapes.
