Publication number: 20200408643Abstract: A tire dynamic load radius calculating device includes a tire rotation sensor, a drum rotation sensor, a drum rotation angle calculating unit, and a tire dynamic load radius calculating unit. The drum rotation angle calculating unit is configured to calculate a rotation angle of a drum per one rotation of a tire based on signals from the sensors. The tire dynamic load radius calculating unit is configured to calculate a dynamic load radius of the tire based on a formula (R=L/2?), using the rotation angle calculated by the drum rotation angle calculating unit. In this formula, R represents a dynamic load radius of the tire, and L represents a distance traveled by the tire per one rotation of the tire.Type: ApplicationFiled: June 11, 2018Publication date: December 31, 2020Applicant: KABUSHIKI KAISHA KOBE SEIKO SHO (KOBE STEEL, LTD.)Inventor: Yuichiro MIZUTA

Patent number: 9308700Abstract: A tire vulcanizing method reduces consumption energy and increases productivity of vulcanization. This method involves supplying an inert gas to an internal space of the tire via a supply pipe, discharging the gas from the internal space via a return pipe, and supplying the gas from the return pipe to the supply pipe by a rotation type circulation device. A heating device heats the circulated gas. An internal outlet gas temperature sensor detects a temperature of the gas in the return pipe. A controller decreases a rotating speed of the circulation device when the return pipe gas temperature is a rotating speed decrease temperature or more.Type: GrantFiled: August 22, 2012Date of Patent: April 12, 2016Assignee: Kobe Steel, Ltd.Inventors: Yuichiro Mizuta, Masahiro Doe, Yasuhiko Fujieda, Masatake Toshima

Patent number: 9028738Abstract: In a tire vulcanizer having two sets of portions, each of which includes a lower mold, an upper mold, and a center mechanism provided with a bladder, a nitrogen gas heated in a first heating device is supplied to an interior of the bladder of the center mechanism which is placed on the upstream side in the circulating direction of the nitrogen gas. The nitrogen gas discharged from the interior of the bladder of the center mechanism is used for vulcanization and patterning and a temperature thereof is lowered. However, this nitrogen gas is heated again in a second heating device, so that the temperature is increased. Therefore, the nitrogen gas heated in the second heating device is supplied to an interior of the bladder of the center mechanism which is placed on the downstream side in the circulating direction of the nitrogen gas.Type: GrantFiled: May 18, 2012Date of Patent: May 12, 2015Assignee: Kobe Steel, Ltd.Inventors: Yuichiro Mizuta, Yasuhiko Fujieda, Masahiro Doe
