To control the position of the traction balls, the axles are guided in curved slots of a turnable iris plate. To control the axial placement of the traction balls, there is a rotatable input disc positioned adjacent to the traction balls, a rotatable output disc positioned adjacent to the traction balls opposite the input disc, and a pre-spanning ring around the traction balls such that each of the traction balls is making three-point contact with the input disc, the output disc and the pre-spanning ring, the contact surface of the pre-spanning ring having a specific curvature larger than the radius of the traction balls. | 2017-10-05 |
20170284520 | INFINITELY VARIABLE TRANSMISSIONS, CONTINUOUSLY VARIABLE TRANSMISSIONS, METHODS, ASSEMBLIES, SUBASSEMBLIES, AND COMPONENTS THEREFOR - Inventive embodiments are directed to components, subassemblies, systems, and/or methods for continuously and infinitely variable transmissions (IVT). In one embodiment, a variator is adapted to receive a control system that cooperates with a shift nut to actuate a ratio change in an IVT. In another embodiment, a neutral lock-out mechanism is adapted to cooperate with the variator to, among other things, disengage an output shaft from a variator. Various inventive mechanical couplings, such as an output engagement mechanism, are provided to facilitate a change in the ratio of an IVT for maintaining a powered zero operating condition. In one embodiment, the output engagement mechanism selectively couples an output member of the variator to a ratio adjuster of the variator. Embodiments of a ratio adjuster cooperate with other components of the IVT to support operation and/or functionality of the IVT. Among other things, user control interfaces for an IVT are disclosed. | 2017-10-05 |
20170284521 | MOTION TRANSMITTING DEVICE, MOLD ASSEMBLY AND MACHINES - A motion transmitting device comprising: a slider movable along a slider guide; and a connecting body movable along a connecting body guide, wherein the slider and the connecting body are disposed in contact with each other, each of the slider and the connecting body has a contact surface that is slidable, and the amount of displacement and/or the speed of displacement of an output end relative to an input end can be reduced or can be made equal to each other or increased through setting of the angle of a center axis line of the slider guide about a center axis line of the connecting body guide and/or the inclination angle of the contact surface. | 2017-10-05 |
