A differential gear includes a differential housing consisting of cast iron and a differential crown wheel consisting of case hardened steel. The differential gear, while being of reproducible quality, can be produced simply and cost-effectively. The differential housing has, on the circumference onto which the differential crown wheel is pressed, a bearing shoulder, to which the differential crown wheel is fastened via a nickel-containing welded joint. The composition of the welded joint is influenced by the use of a nickel-containing additional material which is added to the welding melt in the form of an annular foil arranged between the bearing shoulder and the differential crown wheel.

In an automatic washer drive system, a planetary gear arrangement is provided including an input drive shaft being drivingly connected to a motor at one end and having a sun gear interconnected with a second end. A plurality of cylindrical plastic planet gears are disposed around and engage the sun gear. A plastic unitary carrier member rotatably supports the planet gears and further interconnects with an output drive shaft for causing rotation of an agitator. A gear housing surrounds the cylindrical planetary gears which engage an internal ring gear disposed on an inner peripheral surface of the gear housing. The plastic unitary carrier member is configured to include a plate portion which extends outwardly in the radial direction with respect to the output drive shaft. A plurality of the cylindrical pin portions extend from the plate portion in the longitudinal direction with respect to the output drive shaft. These cylindrical pin portions provide the rotatable support of the cylindrical planet gears. A boss portion extends from a center portion of the plate portion and includes internal grooves for receiving splines disposed on the output drive shaft such that the unitary carrier member and output drive shaft are rigidly interconnected.

A planet-pinion carrier assembly for a planetary gear system includes a planet-pinion carrier having first and second radially extending sections, planet pinions each rotatably mounted onto a pinion shaft through a bearing, a first thrust washer disposed between one axial end of each planet pinion and the first section, and a second thrust washer disposed between the other axial end of each planet pinion and the second section. The first and second thrust washers each have a surface hardness large enough to ensure an improved durability and reliability.

1,048,677. Motor vehicle driving gear. F. A. E. PORSCHE. Jan. 18, 1965 [Jan. 24, 1964], No. 2124/65. Heading B7H. In a vehicle with an aluminium or other light metal differential housing 3 the steel drive shaft 6 carrying the pinion 12 which meshes with the crown wheel 13 (Fig. 2, not shown) is supported in the end walls of the housing by a ball bearing 9 which locates the shaft axially and a needle roller bearing 11 which permits axial shaft movement to accommodate differential expansion of the shaft and housing. The differential casing and crown wheel are carried by a support on each side attached to the housing wall by four bolts, a fitted bolt 22 and bolts 23, 24, 25 which permit relative radial movement of the housing and support due to their different coefficients of expansion. The vehicle engine drives shaft 6 through a clutch in housing 2, shaft 5 within shaft 6 and a gear-box in housing 4.

An automated clutch system for transferring torque from an engine to a change gear transmission is connected to a processing unit which uses various input parameters to calculate the grade on which the vehicle is operating and its current weight to determine an appropriate start gear to minimise clutch slip when the vehicle is launched from rest.

An inscribed planetary gear device usable as a speed reducer or an overdrive has a primary shaft which serves, for example, as an input shaft, an externally-toothed gear carried at an eccentricity by the primary shaft; an internally-toothed gear inscribed by the externally-toothed gear; and a secondary shaft which serves, for example, as an output shaft and connected to the externally-toothed gear, through an Oldham's ring which transmits to the secondary shaft only the rotation of the externally-toothed gear taking place about the axis of the externally-toothed gear. The externally-toothed gear is provided with a counter flange at an end facing the Oldham's ring and is operatively connected to the Oldham's ring through Oldham's projections and Oldham's grooves receiving Oldham's projections provided on the Oldham's ring and the counter flange, respectively, or vice versa. The externally-toothed gear is formed by metal powder injection molding and, during sintering process, is placed on a furnace bed while contacting the counter flange with the furnace bed. In this manner, the sintered gear is prevented from being distorted.

A hollow roller which comprises a hardened outer surface, and a non-hardened inner surface which has not been subjected to carburization process, whereby soft portions remain at the inner surface of the hollow roller in order to prevent the inner surface from being cracked in response to external shock. Preferably, the hollow roller is applied to a planet roller or a cylindrical roller.
摘要:
A starter with a gear reduction mechanism including an internal ring gear formed of synthetic resin and a reinforcing member. The internal ring gear has a cylindrical portion and a toothed portion formed on an inner peripheral surface of the cylindrical portion. The reinforcing member is secured around an outer surface of the cylindrical portion.

A ring gear assembly is also provided with the a transaxle, and includes a ring gear carrying a bevel gear assembly in its interior, both of which are contained in a cavity in the housing for the transaxle. A pair of bearing shoes are directly disposed between the teeth of the ring gear and the housing cavity and between the opposite sides of the ring gear and the housing cavity. The bearing shoes have an arcuately-shaped inner surface against which the ring gear teeth are rotatably placed. During rotation of the ring gear, bearing surface therefor is provided by the teeth of the ring gear and the inner surfaces of the bearing shoes.
