摘要： A gas turbine engine (10) comprises a gearbox (28) comprising a sun gear (30), an annulus gear (32), a plurality of planet gears (34) and a carrier (36). Each planet gear (34) is rotatably mounted in the carrier (36) by a bearing (42). The sun gear meshes with the planet gears and the planet gears mesh with the annulus gear. The sun gear, the planet gears and the annulus gear comprise helical gear teeth. The annulus gear is secured to a surrounding structure by a radially extending member. A face of the flange nearest the middle of the annulus gear is axially spaced from the middle of the annulus gear by a first distance. The reference diameter of the annulus gear is radially spaced from a point at which the radially extending member is secured to the surrounding structure by a second distance. The ratio of first distance to second distance is between and including 0.5 and 1.2 such that misalignment between the annulus gear and the planet gears is reduced to minimise vibrations, noise, stress and wear of the gearbox.

摘要： An epicyclic gear assembly according to an exemplary embodiment includes, among other things, a carrier including a first plate axially spaced from a second plate by a radially outer connector. A first set of epicyclic gears supported adjacent the first plate include a first set of circumferentially offset intermediate gears meshing with a first sun gear and a first ring gear. A second set of epicyclic gears are axially spaced from the first set of epicyclic gears and supported adjacent the second plate, and include a second set of circumferentially offset intermediate gears meshing with a second sun gear and a second ring gear. The first epicyclic gear set and the second epicyclic gear set maintain relative intermeshing alignment during flexure induced deformation of the carrier.

摘要： A gearbox includes a shaft input spherical bearing and a shaft output spherical bearing enabling the ring gear to float within the housing and not engage the housing. The shaft output spherical bearing permits angular displacement of the output shaft with respect to the longitudinal axis of said output shaft. A spline connection enables the ring gear to pivot with respect to the cover. Loads transmitted to the housing of the gearbox are not transferred to the gear systems and the gear systems self-align within the housing.

摘要： A planetary gear transmission has two or more planetary gear sets (2a, 2b, 2c, 2d) in the gear train. Each planetary gear set comprises a sun gear (1) mounted on a sun shaft (5) with the sun gear (1) engaging a plurality of planet gears (2) mounted on a planet carrier (4) with the plurality of planet gears (2) engaging a ring gear (3) mounted on the transmission housing (7). Each gear of the planetary gear transmission is a helical cut gear. Sun gears (1a, 1b, 1c, 1d) and/or ring gears (3a, 3b, 3c, 3d) are mounted for axial movement with respect to the transmission. Thrust imbalances on the sun gears (1a, 1b, 1c, 1d) and/or ring gears (3a, 3b, 3c, 3d) resulting from uneven loading and the helical cut result in sun gears (1a, 1b, 1c, 1d) and/or ring gears (3a, 3b, 3c, 3d) moving in the axial direction to eliminate the thrust imbalances and thereby resulting in equal loading or power sharing amongst the planetary gear sets (2a, 2b, 2c, 2d).

摘要： The invention concerns a planetary gear reduction mechanism, in particular for motor vehicle. Said reduction mechanism comprises a ring gear (30) which includes a fixed outer ring gear part (31) an inner ring gear part (32) bearing inner teeth (33) and shock absorber elements (34). The reduction mechanism is characterized in that the shock absorbing elements (34) are made in the form of plates arranged in housings formed by recesses (36, 37) matching in shape provided respectively in the outer peripheral surface (38) on the inner ring gear (32) and in the inner peripheral surface (39) of the outer ring gear (31), each recess having a depth which increases in a relative angular displacement direction between the two the ring gear parts, from the peripheral surface, over a length (a) corresponding to the length of the plate, up to a value (b) substantially equal to the thickness of the plate. The invention is useful for motor vehicle starters.

摘要： A torque limiting device in accordance with the present invention comprises first and second relatively rotatable elements (38, 39), the first element (38) being hollow and receiving the second element (39) therein, the outer periphery of the second element (39), and/or the inner periphery of the first element (38) being of non-circular cross-section so that the radial dimension of a gap defined between the outer periphery of the second element and the inner periphery of the first element is not constant during relative angular movement of the elements, the device further including an elastic component (41) in said gap between said first and second elements, the, or at least one of the, non-circular peripheries being slidable relative to said elastic component (41) whereby said elastic component is deformed during relative angular movement of the first and second elements (38, 39) and so resists said relative angular movement.
The invention further resides in a starter motor incorporating such a torque limiting device so as to limit torque transfer between the armature of the starter motor and the pinion gear of the starter motor.
