Latest Patents

Nakamura's latest patents include a fixed type constant velocity universal joint. This innovative joint features an outer joint member with eight arcuate guide grooves extending in the axial direction on an inner spherical surface. The inner joint member also has eight arcuate guide grooves on its outer spherical surface. Between these guide grooves, eight balls are positioned, and a cage is interposed to retain the balls. Notably, the centers of the guide grooves in both the outer and inner joint members are offset from their respective spherical surfaces, establishing a specific relationship between wall thickness and radial displacement of the balls.

Another patent by Nakamura is a fixed type constant velocity joint. This design ensures that the angle defined by a straight line connecting the contact points between the cage and the joint members does not exceed 10 degrees. This precision in design enhances the performance and reliability of the joint in various applications.
