A pulley device for a belt that includes an eccentric adjusting member fixed on a support, an eccentric hub rotatably mounted on the eccentric adjusting member, a torsion spring between the eccentric adjusting member and hub to exert a biasing force, and a pulley rotatably mounted on the hub. The hub provides an upper radial surface and the eccentric adjusting member provides a radially outwardly projecting flange formed at an upper end of the eccentric adjusting member and forming an axial abutment for the upper radial surface. The upper radial surface provides a pair of axially projected stops formed integrally within, each stop being dedicated to come into abutment against a corresponding stop provided by the radially outwardly projecting flange of the eccentric adjusting member. The hub further provides engaging means adapted to cooperate with an external tool, the engaging means circumferentially located between the projected stops of the hub.

A tensioning roller/winder device comprising at least one roller bearing including inner and outer rings and at least one row of rolling elements between the two rings; a pulley surmounting the outer ring; and a retaining screw comprising a body and head. An abutment is provided on the body external periphery. First and second abutments are provided on the inner ring bore. The axial length between the head and the abutment equals the axial length between an inner ring radial side edge and the inner ring bore first abutment is greater than the axial length between a inner ring radial side edge opposite the screw head and the inner ring bore second abutment. The screw abutment contacts the inner ring first abutment during the body insertion into the inner ring bore in the desired direction, but contacts the inner ring second abutment during the body insertion in the undesired direction.

A roller screw mechanism comprising a screw having an outer threading; a nut arranged around and coaxially to the screw, the nut having an inner threading; and a plurality of mutually identical rollers interposed between the screw and the nut. Each mutually identical roller having an outer threading engaged with the outer and inner threadings of the screw and of the nut. The threading of each mutually identical roller being prolonged axially at each end by teeth respectively engaged with teeth of two annular crown rings fixed in an unthreaded part of the bore of the nut. Each of the mutually identical rollers comprises an angular visual positioning feature. The nut comprises an angular visual positioning feature making it possible to angularly place the rollers in the crown ring.

One implementation of a shift cable assembly may include a conduit, a core received within the conduit, a rod coupled to an end of the core a slide tube within which a portion of the rod is received and a connector. The connector may have a plastic housing disposed about an end of the rod, a first insert carried by a portion of the plastic housing, a body, a second insert carried by the body, and a fastener interconnecting the first and second inserts. The first and second inserts may engage each other to hold the plastic housing and the body in fixed positions with respect to each other.

A shift actuator comprises a drive shaft and a housing that rotatably supports the drive shaft. A shift position detecting apparatus detects a rotational position of the drive shaft. The drive shaft is connected to a shift mechanism by an operating lever and a shift rod. The operating lever and the housing are respectively formed with a through hole and a bottomed hole. The drive shaft can be temporarily secured in rotational position by inserting a lever positioning pin into the through hole and the bottomed hole. When secured, the shift position detecting apparatus can be attached to the housing and a length of the shift rod can be adjusted.

A method of assembling a fan drive gear system for a gas turbine engine according to an example of the present disclosure includes the steps of providing a unitary carrier defining a central axis and that includes spaced apart walls and circumferentially spaced mounts defining spaced apart apertures at an outer circumference of the carrier, gear pockets defined between the walls and extending to the apertures, and a central opening in at least one of the walls. The method includes the steps of inserting a plurality of intermediate gears through the central opening, moving the intermediate gears radially outwardly relative to the central axis into the gear pockets, inserting a sun gear through the central opening, moving the plurality of intermediate gears radially inwardly relative to the central axis to engage the sun gear, and coupling a fan shaft to the carrier such that the fan shaft and intermediate gears are rotatable about the central axis. A fan drive gear system is also disclosed.
