Latest Patents

Hyun-Il Lee's latest patents include a Constant-velocity universal joint and a Hollow drive shaft with a method for manufacturing the same. The Constant-velocity universal joint features an outer joint member with multiple outer ball grooves and an inner joint member with corresponding inner ball grooves. This design incorporates a unique double shape for the grooves, ensuring optimal performance. The ratio of the offset value to the distance between the center lines is meticulously calculated to fall within a specific range, enhancing the joint's efficiency.

The Hollow drive shaft patent addresses the issue of concentrated loads at weak points due to variations in sectional thickness and outer diameters. This innovation disperses the load, ensuring uniform strength throughout the shaft's length. The design includes a small-diameter portion with a hollow shape and a larger diameter portion nearby, which has a reduced sectional thickness. The carburization process applied to the large-diameter portion enhances its hardness, contributing to the overall durability of the drive shaft.
