Abstract: A variator having at least one roller which runs upon at least one race to transfer drive from one to the other at variable ratio. The variator has a fluid supply for supplying fluid to the race and roller thereby to provide a fluid film by which the roller and the race are separated in use. The roller has a running surface with root means square roughness Rq(roller) and the race having a root means square roughness Rq(race). The variator's specific film thickness is the minimum thickness of the fluid film in normal operation divided by the composite roughness, and is less than 1.0. At least one of the roller and the race has a powder metal surface with a Ra roughness above 0.1 micrometers.

Abstract: Railcar coupling knuckles having areas of improved structure, improved surface characteristics, and reduced stress under loading, and systems and methods for shot peening railcar components such as, but not limited to, coupling knuckles. Such shot-peening systems and methods may include robotic and/or fixed-position shot-peening devices equipped with shot-emitting mechanisms for expelling shot media against desired areas of a railcar component.

Abstract: A modular hydrostatic transaxle includes an axle module removably connected to a hydrostatic transmission module. The axle module includes a differential connected to a reduction gear train and disposed in an axle casing. A pair of axles are connected to the differential and supported within the axle casing. The hydrostatic transmission module comprises a transmission casing separate from the axle casing and hydraulically connected pump and motor disposed in the transmission casing. The motor output connection includes a shaft piloted to an input drive of the reduction gear train, which constitutes the alignment mechanism of the transmission and axle modules. The pump and motor cylinder barrels are hydraulically connected through the pump and motor block at 90° orientation, and a portion of the pump and motor block forms an inclined surface which supports a face of a thrust bearing. At least one homogeneous low friction bearing strip is confined between the swash plate and the interior portion of the casing.

Abstract: A transmission device between a primary motor shaft and a drive shaft for the wheels of self-propelled lawn mowers having a driving member connectable to a motor shaft, an output shaft, and a helically threaded driven gear rotatably mounted and moveable axially on the output shaft, the driven gear including an exterior driving surface and an interior surface, the interior surface including a plurality of teeth fixed in rotation with the gear, the teeth having a sloped leading edge and trailing edges substantially on a plane extending radially outward from the center of the driven gear, the outer engaging surface in constant engagement with the driving member so that the driven gear rotates whenever the driving member rotates.
