  • Patent number: 10605332
    Abstract: A planetary gear assembly (30) and method of assembly in an electric camshaft phaser (20) with a split ring gear including a drive-side ring gear portion (32) rotatable by an engine crankshaft and an output-side ring gear portion (34) that can be connected to a camshaft (22). A plurality of rotatable planetary gears (36a, 36b, 36c) can be interposed between the split ring gear and the sun gear (28). The output-side ring gear portion (34) can have a different number of teeth than the drive-side ring gear portion (32) by a value corresponding to a multiple of the number of planetary gears (36a, 36b, 36c). A compliant planetary gear carrier (40, 140) can support the plurality of planetary gears (36a, 36b, 36c) allowing variance of a normally equidistant distance between separate spaced rotational axes of at least two of the planetary gears (36a, 36b, 36c) to selectively compensate for mechanical tolerances of the drive-side ring gear portion (32) and the output-side ring gear portion (34) of the split ring gear.

  • Patent number: 10107154
    Abstract: A cam phaser (30, 130, 230) dynamically adjusts a rotational relationship of a camshaft (32) of an internal combustion engine with respect to an engine crankshaft operably connected with a phaser sprocket (42, 142, 242). The cam phaser (30, 130, 230) can include a planetary gear assembly having a ring gear (34, 134, 234) driven by the phaser sprocket (42, 142, 242), a planetary gear carrier (36, 136, 236) connected to the camshaft (32), a sun gear (38, 138, 238), and at least one rotatable planetary gear (40, 140, 240).

  • Publication number: 20060096562
    Abstract: A reed valve seat with multiple ports allows a reed valve to operate under extreme pressures in a variable cam timing system. A check valve includes a valve seat in a variable cam timing phaser with a contact surface and multiple ports for fluid in control passages within the phaser to flow through. A reed creates a seal with the contact surface of the valve seat when the reed contacts the valve seat such that reverse flow of fluid in the variable cam timing phaser is prevented.

  • Publication number: 20060070301
    Abstract: A window or door structural member includes an extruded structural member having at least a thermoplastic and filaments disposed within the thermoplastic. The extruded structural member has a thermal coefficient of expansion of 3×10?5 in/in ° F. or less and a heat deflection temperature of 210° F. or more. An acrylic cap is coextruded with the extruded structural member and coupled with the extruded structural member. In one option, the extruded structural member includes at least one of a frame member, sash, or panel, and cladding. In another option, a window or door assembly includes a frame and a cladding coupled along the frame. At least one of the frame, sash, or panel, and the cladding includes one or more extruded structural members including at least a thermoplastic and filaments disposed within the thermoplastic.

  • Patent number: 6106423
    Abstract: A chain tensioning system includes a pair of tensioners located one on each side of a driving sprocket, such as a crankshaft sprocket, between the driving sprocket and each of two driven sprockets, such as balance shaft sprockets. The dual tensioning system provides a tensioner to absorb torsional vibrations from the driving shaft in each of the two relative rotational directions of the driving shaft.
