Abstract: An electrically-actuated variable camshaft timing (VCT) phaser is employed for use with an internal combustion engine (ICE). The electrically-actuated VCT phaser includes a gear set assembly and a fixture. The gear set assembly has an input gear and an output gear, among other possible components. The input gear receives rotational drive input from an engine crankshaft, and the output gear transmits rotational drive output to an engine camshaft. The fixture is secured in the gear set assembly. Amid installation of the electrically-actuated VCT phaser on the ICE, the fixture constrains rotational movement of the gear set assembly. After installation, the fixture can be removed from the gear set assembly.

Abstract: An electrically-actuated variable camshaft timing (VCT) phaser assembly, comprises a sun gear configured to receive input from an electric motor and one or more planet gears having radially-outwardly-extending gear teeth that engage the sun gear; a first ring gear, having radially-inwardly extending gear teeth that engage the radially-outwardly-extending gear teeth of the sun gear, configured to receive rotational output provided by a crankshaft; a second ring gear, having radially-inwardly extending gear teeth that engage the radially-outwardly-extending gear teeth of the sun gear, configured to couple to a camshaft; one or more planet gear pins that carry the planet gear(s) and engage a planetary gear set to prevent the relative rotation of the planet gear pin(s) relative to the planetary gear set; and one or more springs that bias the planet gear pin(s) and the planetary gear(s) toward the first ring gear and the second ring gear.

Abstract: A tensioner (10) for an endless loop power transmission member can include the assembly of a plunger (12) operably engageable with an endless loop power transmission member, and a piston (14) guiding the plunger (12) for sliding coaxial movement in a direction of the endless loop power transmission member and defining an oil reservoir (26) for receiving hydraulic fluid. A bearing (28) can have bearing balls (30) located in a counter bore (32) coaxial with piston bore (34). The counter bore (32) can have a steep taper (36) on which the bearing balls (30) ride, such that as the plunger (12) moves in an extending direction, the bearing balls (30) move out of the counter bore (32) allowing free extending movement of the plunger (12), and as the plunger (12) moves in a retracting direction, the bearing balls (30) are driven down into the steep taper (36) preventing the plunger (12) from retracting.
