Latest Patents

Ohuchi holds a patent for a differential device and method of manufacturing the device. The differential apparatus comprises a casing that is rotated by an external driving force. It features a pair of opposing disc plates that are coaxially disposed within the casing. Each disc plate has a circumferentially continuous groove that winds in such a way that the radial position changes at a constant period. The design includes a plurality of balls that roll within the opposing winding continuous grooves of both disc plates. Additionally, a ball holder rotates integrally with the casing and contains multiple radially extending guide holes, each of which movably receives a ball. The winding continuous groove of each disc plate has first and second guide regions that connect through inflected regions, which are larger in width and/or depth than the first and second guide regions. This design effectively decreases the contact stress between the balls and the winding continuous groove in the inflected regions.
