Patent number: 9879763Abstract: A chain guide includes a curved guide base extending along the direction in which a torque transmitting chain moves. The guide base includes, on its surface opposed to the chain, a rolling guide portion including a plurality of roller element bearings which are rotatable and configured to guide the chain while kept in rolling contact with the chain, and a sliding guide portion in the form of a curved surface. The rolling guide portion reduces a loss in torque transmission, while the sliding guide portion reduces flapping of the chain, thus reducing noise and vibrations of the chain.Type: GrantFiled: March 27, 2015Date of Patent: January 30, 2018Assignees: NTN CORPORATION, BORGWARNER MORSE SYSTEMS JAPAN K.K.Inventors: Akio Kato, Takahiro Yamashita, Hisataka Hasegawa, Shinji Tsuruta, Hiroyuki Fukuyama, Nobuhiro Mizuno

Publication number: 20060100048Abstract: A tensioning device to impart tension to a chain or belt comprising a tensioner arm, a supporting member, a pivot, and a biasing element. The tensioner arm has a proximal end with a curved engaged surface formed on a lower surface thereof, a distal end opposite the proximal end, and an arcuately curved chain sliding surface extending between the proximal end and the distal end. The supporting member has an engaging surface for slidably contacting the engaged surface of the proximal end of the tensioner arm, such that the force exerted by a chain passing over the chain sliding surface is transmitted from the engaged surface to the engaging surface. The pivot couples the tensioner arm to the supporting member. The biasing element is between the supporting member and imparts a resilient force on the distal end of the tensioner arm.Type: ApplicationFiled: November 8, 2004Publication date: May 11, 2006Applicant: BorgWarner Inc.Inventors: Junichi Wake, Shin Seungpyo, Yukio Yoshida, Simon Barrette, Cai Lei, J.
