An output ring gear for use in an integrated drive generator has a gear body extending between a first end and a second end and having a disc extending radially outwardly. A boss extends from the disc toward the second end. There are outer gear teeth outwardly of an outer diameter of the disc. There are inner gear teeth inwardly of an inner surface of the disc. The outer and inner gear teeth have a unique gear tooth profile with roll angles A, B, C, and D. An integrated drive generator and a method are also disclosed.

An annular power transmission element with a longitudinal axis that has a first annular part, a second annular part with torque transmission means and a third annular part. The first, second and third annular parts are integral with each other. The first annular part and the third annular part are made of a first metallic material and the second annular part is made of a second metallic material having a density greater than the density of the first metallic material. The second annular part is locked longitudinally between the first annular part and the third annular part and radially on the first annular part, the first annular part is in contact with the third annular part and welded thereto.

A chain block comprises: a first rotary body in which a first tooth part f is arranged; a second rotary body comprising a second tooth part which opposes to a first tooth part with magnetic attraction force and releasing the magnetic coupling state by sliding toward thrust direction; a clutch pin integrally provided with the second rotary body; a clutch receiving member comprising a plurality of recessed pockets to which the clutch pin enters according to a slide of the second rotary body; wherein the plurality of pockets comprise; a hoisting-side pocket in which a magnetic member is arranged; a lowering-side pocket in which a magnetic member is arranged; and an intermediate pocket which exists between the hoisting-side pocket and the lowering-side pocket and which the clutch pin enters in a state of not being magnetically attracted.

An assembly includes a first planetary stage, a second planetary stage, and at least one retainer plate. The first planetary stage has a planet carrier and the second planetary stage has a ring gear. The planet carrier and the ring gear are configured to be rotated about a common axis of rotation. The retainer plate is attached to the ring gear and engages in a groove in the planet carrier. The groove and the axis of rotation are at least partially skewed to each other. The retainer plate is arranged at least partially on a first side of a first plane and on a first side of a second plane. The first plane and the second plane intersect along the axis of rotation. All planet bolts fixed in the planet carrier each lie on a second side of the first plane and/or the second plane.

A steering apparatus includes a first pinion, an internal gear engaged with the first pinion, a second pinion fixed relative to the internal gear, a first gear engaged with the second pinion, a third pinion fixed relative to the first gear, and a steering rack meshed with the third pinion.

The present disclosure discloses an automatic clutch winch comprising a motor, a gear reduction unit actuated by the motor, and a winding drum drivably coupled with the gear reduction unit. The gear reduction unit comprises a planetary gear assembly drivably coupled with the winding drum, a movable ring gear engaging with the planetary gear assembly, a DC gear motor, a cam driven by the DC gear motor to rotate, and a pull rod driven by the cam. The pull rod is driven by the cam on a first end to enter or exit a notch of a plurality of notches in the movable ring gear. The disclosed automatic clutch winch can provide protection for the internal components during an emergent situation.

A housing for a motor-transmission unit with at least two housing sections which have in each case at least one accommodation segment for receiving a motor and an internally-toothed, internal ring gear segment for receiving a gear of a planetary gear unit, wherein the housing sections can be or are connected with each other and wherein, in the assembled state, the accommodation segments of the housing sections together form at least one accommodation compartment for holding the motor, and the internal ring gear segments of the housing sections together form an internal ring gear for mating with a gear on the planetary gear unit.

A motor vehicle transmission assembly is provided that includes a dampening component configured to reduce at least one of noise and vibration within the transmission assembly. In some versions, the dampening component is disposed between first and second transmission components, and the dampening component may be fixed to and/or abutting one of the transmission components. The dampening component may comprise a dampening layer disposed between a pair of outer layers. In some versions, the dampening component has a metallic portion and a non-metallic portion.

The present disclosure provides an internal ring gear, a driving assembly having the internal ring gear, and an application device employing the driving assembly. The internal ring gear includes at least two ring gears integrally arranged in parallel at an inner surface of a single housing.

It has been found that duplex monolithic parts can be manufactured in high volume at low cost by using powder metal technology to mold and sinter an inner component of the part into an outer component of the part. This technique reduces the cost of manufacturing intricate metal products by taking advantage of the attributes of powder metal technology in making the inner component of the part. The outer component of the part can be wrought machined, stamped or forged, or made by double press double sinter or forging a powder metal component of the part. In any case, this technique can beneficially be used in making a wide variety of toroid parts, such as gears, clutches, sprags, bearing races, one-way diodes, and the like.
