The biasing member is disposed...

20060035738 - Belt drive: A belt drive is provided, especially a timing-belt drive for an internal-combustion engine, with a driving gear of a driveshaft, at least one driven gear of a driven shaft, and a belt means, wherein the driving or the driven gear imparts additional irregularity to the belt drive due to its...

20060035739 - Compound gearing system and method with chain and belt engagement structures: A compound gear system and method comprising a flexible gear defining an array of gear elements in an articulating relationship, a rigid structure defining first and second spaced parallel pluralities of articulating gear support structures arrayed in a ring, the articulating gear reeved tightly about and engaging the support structures,...

20060035740 - Timing belt tensioner with stops controlled by frictional brake: A tensioner (10) features a backstop device (40) which allows free rotation of the pivot arm (20) in one direction but not the other. Reverse rotation is prevented by friction that is able to resist torque on the pivot arm (20) under ordinary operating conditions which otherwise could permit belt...

20060030440 - Bicycle chain guide assembly allowing use of multiple chainrings for indirect chain drives of suspension bicycles: A lower chain guide assembly to allow the use of multiple chainrings and front derailleur systems on indirect-drive chain driven bicycles....

20060030441 - Torsional damper pulley: A torsional damper pulley improved in general versatility, easily produced and capable of reduction in production cost. The torsional damper pulley is constructed of a hub 11 fixed at a revolving shaft of an internal combustion engine, an annular pulley body 10 coaxially placed at an annular fixing portion 11b...

20060030442 - Transmission chain: Transmission chain constructed from a number of links intercoupled by pivot assemblies, each comprising a first and a second elongated pin of which at least one cooperates with its ends, while transmitting a force, with a pair of pulley sheaves, while during operation one pin rolls with a curved longitudinal...

20060030443 - V-shaped belt, belt-type transmission, and saddle type-vehicle: To enhance the durability of the V-shaped belt by allowing the strength and the heat-radiating property of the resin blocks to stand together at high levels in the V-shaped belt, which has a plurality of resin blocks and endless connecting members connecting the resin blocks. The V-shaped belt includes a...

20060030444 - Timing belt rail assembly: Timing belts are used in industry for precise motion control on a variety of applications. The Timing Belt Rail Assembly facilitates the joining of a polyurethane timing belt of all pitches to be made endless with a hand held heater. The invention makes the disassembly of machinery unnecessary in order...

20060025255 - Mower incorporating a mule drive: The present invention provides a mule drive for use with a mower having a substantially horizontally-disposed output shaft. The mower includes a cutter deck having at least one rotatable cutter driven by a substantially vertically-disposed driven shaft. The mule drive includes a first idler pulley coupled to the mower for...

20060025256 - Blade tensioner: A blade tensioner includes a blade shoe with a chain sliding face bending in an arch-like shape and a blade spring, arranged on a side opposite to the chain sliding face of the blade shoe, that applies spring force to a chain through the blade shoe. The tensioner also includes...

20060025257 - Pulley rotatingly supporting device: In the invention, as the above pulley rotation support apparatus, there is used a three-point-contact-type or four-point-contact-type radial ball bearing (14b). An offset quantity δ, which is an axial-direction distance between the center α of a radial load applied from the endless belt (11) to the driven pulley (4b) and...
