  • Patent number: 11578760
    Abstract: An input gear assembly in which the input gear is coupled to the input shaft via a pair of spaced-apart pilot regions of the input shaft. One of the pilot regions is disposed adjacent to one of the bearings used, with the pilot region formed in or on the input shaft itself and engaging a corresponding internal surface of the input gear. Another of the pilot regions is formed in the inner bearing raceway of another of the bearings used, with the pilot region formed as an elongate portion of the inner bearing raceway of the input shaft and engaging another corresponding internal surface of the input gear. For manufacturing simplicity, this additional pilot region and the remainder of the elongate inner bearing raceway have the same material properties, surface treatment, straightness, and cylindricity. This arrangement prevents tilting of the input gear with respect to the input shaft and bearing shaft, thereby enhancing performance.

  • Publication number: 20220253876
    Abstract: A system, method, and computer program are provided for a path-finding analytic tool that operates on customer data. In use, customer data that includes a plurality of customer profiles stored for a plurality of customers of a business entity is accessed. Each customer profile includes values for: one or more non-actionable features, and one or more actionable features. At least a 3D map is generated from the customer data, where each point on the map represents a different customer profile, and where at least one dimension of the map represents a target feature. A path is determined between a first point on the map representing a first customer profile and a second point on the map representing a second customer profile, for identifying at least one actionable feature in the first customer profile capable of having its value modified to optimize the target feature corresponding to the first customer profile.
