Publication number: 20190093711Abstract: A power transmission shaft performs a fuse-like function when excessive torque is applied to a power input side. The power transmission shaft includes: a main shaft connected to a power device; flanges connected to the power device and provided at both sides of the main shaft; and a flexible coupling extending in the radial direction of the main shaft. The power transmission shaft includes a power shutoff unit which shuts off power by breaking the main shaft or the flanges when torque greater than a predetermined level is applied. When excessive torque is applied to the power input side, the power transmission shaft performs a fuse-like function with respect to the excessive torque, thereby enhancing safety, preventing sparks from occurring at the time of the breakage, facilitating the production thereof, and effectively preventing vibration while sufficiently supporting the speed or load in the event of a high rotation rate.Type: ApplicationFiled: March 2, 2015Publication date: March 28, 2019Inventors: MUN KI LEE, JAE DEOK KO, KEUM MO KIM, SOON JONG SONG, JI MAN LEE, YOUNG WON CHOI, JEONG CHAN LEE, JIN HO PARK, BYUNG GI KIM

Patent number: 9884404Abstract: Foam items may be buffed using particles such as particulate sodium bicarbonate in accordance with the present invention. Foam items may be, for example, expanded EVA foam items pre-formed into an intermediate size and shape. A skin layer may be formed during the expansion of the foam item to form an expanded foam item which may be entirely or partially removed by buffing the item using particles projected with selected buffing parameters. The buffing parameters may be varied based upon the thickness of at least a portion of the skin layer and/or the desired degree of moldability for the foam item after buffing. Particulate sodium bicarbonate or other types of particles used for buffing may be recycled and reused for further buffing of foam items.Type: GrantFiled: October 22, 2013Date of Patent: February 6, 2018Assignee: NIKE, INC.Inventors: Patrick Conall Regan, Dong Woo Lee, Geun Rok Park, Dong Youp Yang, Yong Joo Chon, Byung Gi Kim, Sang Gyu Lee, Jong Cher Seo

Publication number: 20170343051Abstract: A power transmission shaft which alleviates phenomenon in which stress is concentrated on a specific portion of a diaphragm to improve fatigue life span. The power transmission shaft connects a power apparatus and includes a flexible coupling, which is configured by a hub unit positioned inside in a radial direction. A rim unit is positioned outside in a radial direction of the hub unit. A flexible diaphragm unit is positioned between the hub unit and the rim unit. The thickness in the axial direction of the flexible diaphragm unit, from the hub unit toward the rim unit, becomes thinner then thicker to have a minimum thickness interval. The flexible diaphragm unit has a contoured first side on one side in the axial direction and a contoured second side on the other side. The first side has a first inflection point and the second side has a second inflection point.Type: ApplicationFiled: March 3, 2015Publication date: November 30, 2017Inventors: MUN KI LEE, JAE DEOK KO, KEUM MO KIM, SOON JONG SONG, JI MAN LEE, YOUNG WON CHOI, JEONG CHAN LEE, JIN HO PARK, BYUNG GI KIM
