Patent number: 7264565Abstract: A transfer guide for a high-speed power transmission, which can cancel a change in a transmission chain speed so that smooth transmission timing can be realized and a driving power and vibration noises of the transmission chain can be significantly reduced. A curve track T for a transfer guide 100 for a high-speed power transmission disposed in a transfer position X2 just before a transmission chain, which is traveled at a fixed speed by pressing the chain on the inner circumferential side of the chain with a travel limiting guide R, is meshed with a sprocket S, is defined along an movement passage of the roller C2 in the transfer position X2. Thus, the change in the transmission chain speed is canceled so that smooth transmission timing can be reliably realized and the driving power and vibration noise of the transmission chain can be significantly reduced.Type: GrantFiled: January 27, 2004Date of Patent: September 4, 2007Assignee: Tsubakimoto Chain Co.Inventors: Kenshi Suzuki, Masatoshi Sonoda

Patent number: 5397275Abstract: For damping undesirable whipping of a bicycle sprocket chain, especially of a mountain bike when it is being ridden rapidly downhill over rough terrain, and thereby preventing chain suck, a segment of the return run of the chain extending tangentially forwards from the pitch circle of the idler sprocket towards the pitch circle of the drive sprocket in use, is encased within a tube. The tube is mounted by a bracket to the axle of the idler sprocket, and is loose and slippery enough to permit desirable running of the drive chain, while restraining and preventing undesirable deviations, especially in a vertical plane (i.e., transversally or laterally of the running path of the drive chain). Conveniently, the tube may be a self-recoiling longitudinally split member for ease of installation on the chain, and its bracket can be springly clipped over the conventional mounting structure of the idler sprocket.Type: GrantFiled: September 14, 1993Date of Patent: March 14, 1995Inventor: Howard P. McJunkin, Jr.

Patent number: 4609365Abstract: A universal or ball pivot-link chain is guided in two substantially tubular-shaped guide channels and is deflected or turned between such guide channels by means of a driven chain or sprocket wheel. At its circumference the chain wheel possesses a profiled structure formed by recesses or depressions which substantially correspond to the profile or outer contour of the universal link chain. The guide channels extend to the circumference of the chain wheel and form in conjunction therewith a respective transfer or transition region. At each such transfer region the chain wheel protrudes by an amount, essentially corresponding to the depth of the recesses, into the interior of the related guide channel. At such transfer or transition regions the chain links are guided both by the chain wheel and the guide channels. Consequently, there is ensured for a gentle and jerk-free transfer of the chain links from the chain or sprocket wheel to the guide channels and vice versa.Type: GrantFiled: October 4, 1982Date of Patent: September 2, 1986Assignee: Feramatic AGInventor: Jurg Eberle
