Provided is a structure for connecting an engine to a hybrid transmission, the structure including: a connecting unit connected to a rotor shaft at the opposite side and having an edge portion connected to a mass body by a connecting plate; and a drive plate positioned at a side close to a crank shaft so as to be opposite to the connecting unit, the drive plate being configured to connect the mass body and the crank shaft.

A joint assembly for connecting a first rotating part and a second rotating part. The joint assembly includes a constant velocity joint that has an inner race for being connected to the first rotating part and an outer race that is pivotable relative to the outer race. A mating flange couples the outer race to the second rotating part. The outer race and the mating flange each have a radially inner surface. A piloting cover is positioned axially between the outer race and the mating flange and radially supports the radially inner surface of the outer race at a first pilot point, and radially supports the radially inner surface of the mating flange at a second pilot point for centering the outer race relative to the mating flange. The first and second pilot points are located radially inwardly of a bolt circle diameter.

A mixing system includes a housing having a motor mount rotatably coupled thereto, the motor mount having a passage extending therethrough. A drive shaft is removably positioned within the passage of the motor mount. A cap includes a main body removably coupled to the motor mount and an actuator coupled to the main body so as to be pivotable between a first position and a second position with respect to the main body. The actuator producing a camming action when the actuator is pivoted such that when the actuator is in the first position, the actuator pushes the drive shaft against the motor mount so that the main body is locked to the motor mount and so that rotation of the motor mount causes rotation of the drive shaft and when the actuator is in the second position, the actuator is disengaged from the drive shaft and the cap is removable from the motor mount.

The present invention relates to a speed reducer for a vehicle. The speed reducer includes: a first coupler having, on one side thereof, a first coupling portion, to which a motor shaft or a worm shaft is coupled, and, on the other side thereof, a plurality of first protrusions, which are spaced apart from each other in a circumferential direction while protruding in an axial direction, in which the first protrusions are formed in a manner in which a circumferential width of each of the first protrusions is narrowed toward an inner side from an outer side so as to form a first outer support portion as a radial outer end and a first inner support portion as a radial inner end; and a second coupler configured to be coupled to the first coupler to transmit a rotational force to the first coupler.

A gas turbine engine according to an example of the present disclosure includes, among other things, a propulsor section including a propulsor supported on a propulsor shaft, a turbine section including a turbine shaft, and an epicyclic gear train interconnecting the propulsor shaft and the turbine shaft. The epicyclic gear train includes a sun gear coupled to the turbine shaft, intermediary gears arranged circumferentially about and meshing with the sun gear, a carrier supporting the intermediary gears, and a ring gear including first and second portions each having an inner periphery with teeth intermeshing with the intermediate gears. The first and second portions have axially opposed faces abutting one another at a radial interface and respective flanges extending along the radial interface radially outward from the teeth. The first and second portions define a trough axially between and separating the teeth of the first portion from the teeth of the second portion. The first and second portions include facing recesses that form an internal annular cavity along the radial interface.
