Patent number: 11592043Abstract: A clamping unit includes a case with a contact surface, an operation member arranged movable in a pressing cancellation direction and a pressing promotion direction relative to the case, a pressing body arranged in a movable manner in the case to oppose the contact surface, and a movable body between the pressing body and contact surface. At least one of the contact surface, movable body, and pressing body includes an inclined surface. The inclined surface increases a protruding amount of the pressing body from the case when the movable body changes in position as the operation member moves in the pressing promotion direction and eases pressing of the movable body against the pressing body when the movable body changes in position as the operation member moves in the pressing cancellation direction to permit a decrease in the protruding amount of the pressing body from the case.Type: GrantFiled: December 10, 2019Date of Patent: February 28, 2023Assignee: NABEYA BI-TECH KABUSHIKI KAISHAInventors: Kenji Uemori, Hirofumi Mitsui

Patent number: 11486450Abstract: A shaft coupling includes a drive hub that is coupled to a drive shaft to rotate integrally with the drive shaft, a driven hub that is coupled to a driven shaft to rotate integrally with the driven shaft, and a rotation transmission portion that transmits rotation between the drive hub and the driven hub. A dynamic vibration absorber is integrally coupled to a section of at least one of the drive hub and the driven hub. The section is an uninvolved section that is not involved in a torsional stiffness of the whole shaft coupling.Type: GrantFiled: January 27, 2017Date of Patent: November 1, 2022Assignee: NABEYA BI-TECH KABUSHIKI KAISHAInventor: Akira Isobe

Patent number: 11199207Abstract: The motion guide device clamper mechanism includes a clamper main body connected to the movable member, an inner face having a tapered shape so that the distance between the facing faces is narrower toward the end of one face of the track member, and one rolling member disposed between the facing faces of the one face of the track member and the inner face. The rolling member receives a pressing force toward a position where the distance between the facing faces of one face of the track member and the inner face of the clamper main body is narrow, so that a frictional force based on the taper shape acts on the rolling member, and the restraint of the clamper main body with respect to the track member is performed. Further, a frictional force based upon the taper shape is released and the non-restraint of the clamper is performed.Type: GrantFiled: March 6, 2018Date of Patent: December 14, 2021Assignees: THK CO., LTD., NABEYA BI-TECH KABUSHIKI KAISHAInventors: Hiroaki Mochizuki, Hiroomi Kuribayashi, Keisuke Hagiwara, Masahiro Aoyama

Publication number: 20180355898Abstract: A slotted-type rigid coupling is manufactured so that the internal-diameter dimension of a first shaft hole of a circumferentially divided shaft-fastening part is the same as that of a shaft. The first shaft hole is widened by widening force from a pressing mechanism provided with a fastening bolt, and the shaft is inserted through the first shaft hole up to a shaft insertion hole. The widening force is ceased, the first shaft hole is narrowed by fastening force from the pressing mechanism, and the shaft is securely fastened. When the shaft is securely fastened to the shaft-fastening part by the fastening bolt, eccentricity in the shaft is prevented or minimized.Type: ApplicationFiled: December 3, 2015Publication date: December 13, 2018Applicants: HARMONIC DRIVE SYSTEMS INC., NABEYA BI-TECH KABUSHIKI KAISHAInventors: Norio Shirokoshi, Kei Yamada
