Latest Patents

Kohara's latest patents include innovative designs for fixed-type constant velocity universal joints. One of his inventions features a design that allows for sufficient lubrication between a torque transmitting ball and a guide groove, effectively reducing frictional force. This design includes an outer joint member filled with lubricant, which has a guide groove extending in an axial direction on its spherical inner circumferential surface. The inner joint member, positioned on the inner diameter side, also features a guide groove that extends axially. A torque transmitting ball is interposed between the opposing guide grooves, allowing it to roll freely, while a cage holds each ball in place. Another patent describes a fixed-type constant velocity universal joint with an outer joint member that has an inner spherical surface containing multiple track grooves. These grooves are paired with those of the inner joint member, which also has an outer spherical surface with corresponding track grooves. A cage is interposed to hold the balls, ensuring effective torque transmission.
