| 474162000 | Having belt-engaging surfaces on discrete circumferentially spaced, relatively movable or replaceable members | 7 |
| 20100081532 | Drive tumbler - A drive tumbler comprises a hub having attached thereto a plurality of replaceable rim segments. The rim segments are supported by a plurality of raised blocks that are formed integral with the hub and serve to absorb the shear forces to which the tumbler is subject during operation. | 04-01-2010 |
| 20110300978 | TIMING PULLEY - There is provided a timing pulley whose noise is low, which is light-weight, whose pulley structure is simple and which excels in workability. The timing pulley comprises a cylindrical timing hub which is fitted around a power transmitting shaft, a pair of flange members provided apart on both end portions of the timing hub and a plurality of engagement pins disposed on peripheral edge portions of the pair of flange members in the circumferential direction thereof so as to extend between and through each of the flange members and so as to engage with mating teeth of a timing belt. | 12-08-2011 |
| 20110306453 | METHOD OF MANUFACTURING SPROCKET SEGMENT, AND SPROCKET SEGMENT - A method of manufacturing a sprocket segment that is formed by forging as one of a plurality of circumferentially divided parts of a sprocket having a plurality of teeth arranged on an outer peripheral surface of a circular flange, the method includes: forming a material of the sprocket segment into an initial formed state in an initial forming step; and subjecting the sprocket segment in dies to a finish forming process with a tooth trace direction of the sprocket segment as viewed in cross-section of the sprocket segment being inclined relative to a forging direction of the dies in a finish forming step. | 12-15-2011 |
| 20140080645 | SPROCKET ASSEMBLY AND A METHOD FOR INSTALLING A REMOVABLE TOOTH ON A SPROCKET FRAME - A sprocket assembly is provided. The assembly includes a sprocket frame having a central body and a first ledge portion body. The first ledge portion has a first aperture extending therethrough. The assembly further includes a first removable tooth having a first tip portion, first and second landing portions, and a first extension portion. The first tip portion has first and second sides and first and second ends. The first extension portion extends from the second end and has an aperture extending therethrough. The assembly further includes a first bolt extending through the first aperture in the first ledge portion and the aperture in the first extension portion to removably couple the first extension portion to the first ledge portion. | 03-20-2014 |
| 20150126316 | Additional Methods and Devices for Improving the Performance of CVTs - Methods and devices for improving the performance of CVT's (Continuous Variable Transmissions) that utilize a cone with one torque transmitting member, a cone with two opposite torque transmitting members, cone with one tooth (single tooth cone), and a cone with two opposite teeth. Said methods and devices include but are not limited to: a “cone with two opposite slide-able teeth” (see FIGS. | 05-07-2015 |
| 20160061310 | SPROCKET ASSEMBLY AND A METHOD FOR INSTALLING A REMOVABLE TOOTH ON A SPROCKET FRAME - A sprocket assembly is provided.
