A pulley device for a tensioner roller or winding roller of a transmission element, providing a pulley, and a bearing. The bearing includes a rotating outer ring mounted to the pulley, a fixed inner ring, and at least one row of rolling elements arranged between the rings. The inner ring of the bearing has at least one end portion protruding axially with respect to the outer ring. The pulley is provided with at least one pulley element that is C-shaped in axial section. One of the at least one pulley elements is provided with a lateral portion extending substantially radially to pass into the immediate vicinity of an outer surface of the axially protruding end portion of the inner ring.

A transmission includes a transmission main housing, an intermediate plate secured to the transmission main housing; and a rear housing attached to the intermediate plate. An input shaft is connected to an extension shaft including a plurality of splitter gears selectively couple-able to the extension shaft. A main shaft is rotatably supported on the extension shaft and includes a plurality of main box gears selectively couple-able to the main shaft. A range shaft is drivingly connected to the main shaft and provides input to a planetary gear assembly, the range shaft being supported by a first bearing disposed within the intermediate plate and further including a bore disposed within a forward end. The extension shaft is supported at a first end by a bearing assembly within a partition wall and a second end is supported by a bearing assembly disposed within the bore in the range shaft.

A pulley device for a tensioner roller or winding roller of a transmission element, having a fixed inner element, a rotating outer element that is mounted to rotate coaxially about the fixed inner element, and an annular protective flange having a substantially radial portion bearing against a front surface of the fixed inner element. The flange includes an annular folded portion extending substantially axially from an outer edge of the flange and passing radially into the immediate vicinity of an axially protruding annular portion of the rotating outer element to form a narrow passage.

A geartrain assembly includes a first gear, a second gear, and a third gear. A linkage connects the first gear and the second gear, and defines an assembly location of the third gear to connect the third gear to the first and second gears in a manner that minimizes a backlash in the geartrain assembly.

A pulley device for a tensioner roller or winding roller of a belt, including a bearing, a pulley mounted to the bearing, a protective flange and a screw. The protective flange having at least one tongue provided with a plastically deformable part that can pass from a first, undeformed configuration for the insertion of the screw to a second, deformed configuration for axially and radially retaining the screw.

A pulley device for a tensioner roller or winding roller of a transmission element, having a fixed inner element configured to receive a screw, a rotating outer element that is mounted to rotate coaxially about the fixed inner element and is intended to cooperate with the transmission element, and an annular protective flange bearing against a lateral surface of the fixed inner element. The fixed inner element provides a sleeve axially protruding from the lateral surface. The flange provides an inner axial portion mounted securely on an outer surface of the sleeve.

A gear assembly including a rim gear with an inner circumference having one or more beveled surfaces. The rim gear is mounted on a one or more corresponding tapered rollers on a gear mounting assembly. The tapered rollers can engage with the beveled surfaces at an angle relative to an axis of rotation of the tapered rollers and the rim gear to prevent slippage between the inner circumference (beveled surfaces) and the tapered rollers.

A counter rotating gear case. The counter rotating gear case may include a forward gear assembly; an aft gear assembly; a pinion gear assembly; a spool adapter having a first portion and a second portion, wherein the forward gear assembly, the aft gear assembly, and pinion gear assembly may be supported on the second portion of the spool adapter; and wherein, the pinion gear assembly may be disposed between the forward gear assembly and the aft gear assembly, and wherein the pinion gear assembly may be operatively engaged with both the forward gear assembly and the aft gear assembly, such that rotation of one of the forward gear assembly or the aft gear assembly in one direction causes rotation of the other of the forward gear assembly or the aft gear assembly in a second direction opposite that of the first direction.

A dual transmission with input shafts, output shafts, a transmission case and two separate single transmissions arranged in the transmission case is described. Each single transmission is a two-stage spur gear transmission with three positions for gear centers. A first position is occupied by an input shaft and a second position by an output shaft. A third position is for a middle stationary axle fixed to the transmission case. The three positions define a triangular arrangement having a first side defined by a distance between the first position and the second position, a second side defined by a distance between the first position and the third position, and a third side defined by a distance between the second position and the third position. The second side and the third side form respective angles with the first side. At least one of these angles has a value ranging between 5° and 70°.
