A lubricant which is introduced into the rail (16a) via the lubricant channel (13) brings about a pressure gap (15) which is formed between the inner side of the drawing means (2) and a guide face (9) of the rail (16a). Direct contact of the drawing means with the rail (16a) is suppressed on account of the lubricant which is introduced into the pressure gap (15), which has a friction-reducing effect.Type: ApplicationFiled: November 10, 2005Publication date: December 31, 2009Applicant: SCHAEFFLER KGInventors: Rainer Pflug, Christoph Schroeder, Martin Assel

Publication number: 20090111626Abstract: In a chain transmission, the guide-contacting portions of inner and outer plates of a chain each comprise a pair of front and rear flat surfaces, an intermediate concave oil-retaining surface and convex connecting surfaces. The lengths of the flat surfaces are such that adjacent flat surfaces of overlapping inner and outer plates overlap even when the plates in contact with the portion of a convex guide surface having the smallest radius of curvature.Type: ApplicationFiled: August 8, 2008Publication date: April 30, 2009Applicant: TSUBAKIMOTO CHAIN CO.Inventors: Takashi Tohara, Tatsuya Konishi, Toyonaga Saitoh

Publication number: 20080026893Abstract: A chain-type driving force transmitting apparatus includes a case having a lower space accumulating therein lubricating oil, an input shaft rotatably supported by the case, an output shaft arranged in parallel with the input shaft and rotatably supported by the case, and a chain wound around the input shaft and the output shaft and lifting up the lubricating oil accumulated in the lower space of the case. The chain-type driving force transmitting apparatus further includes a separator positioned adjacent to the chain and dividing the lower space of the case into a first chamber housing the chain and a second chamber. The separator has an inclined portion formed at an upper end of the separator and inclining towards the chain so as to receive the lubricating oil lifted up by the chain, wherein the lubricating oil received by the inclined portion flows into the second chamber.Type: ApplicationFiled: July 24, 2007Publication date: January 31, 2008Applicants: AISIN AI CO., LTD., TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Osamu YAMAMOTO, Toru Inoue, Shinji Kitaoka, Yukio Ueda, Akifumi Kamitanigawa, Satoshi Munakata

Patent number: 6971966Abstract: A belt damper for a gear train is provided. An endless belt is wrapped around pulleys mounted to an idler gear and an output gear. The pulleys are mounted to splined shafts which are axially aligned with and connected to splined gear shafts on which the idler and output gears are mounted. Pressurized lubricant is supplied to both splined connections. The combination of the lubricant in the spline connections and the damping effect of the belt provides for an effective damping system. A tension device may also be applied to vary tension imposed on the belt.Type: GrantFiled: October 23, 2003Date of Patent: December 6, 2005Assignee: Caterpillar Inc.Inventors: Robert C. Gibson, Kevin J. Knox, Marvin P. Schneider, Michael J. Smith
