An overload protection device in combination with a prime mover and gearbox transmission supplies torque through a gearbox transmission to a load. An input shaft with is driven by the prime mover and rotates therewith. An external spline on the input shaft mates with an input gear having an internal spline. Upon ove...

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 spli...

A wheel drive assembly includes a rotatable spindle-carrier affixed to a wheel. A fixed housing includes an output ring gear and the spindle-carrier resides generally within the housing. An output sun gear driven by an input carrier drives output planetary gears which, in turn, interengage the output ring gear drivi...

A steerable wheel motor assembly for moving construction lifts and scaffold equipment is disclosed and claimed which includes a spindle bracket configured to be pivotably mounted at an upper end to a steering mechanism for rotation about a vertical axis. The output shaft is supported by a first set of bearings and a...

A bearing lubrication device in a right angle gear reducer includes a gear hou having an interior portion and a lubricating fluid reservoir therein. An oil slinger, rot pinion shaft, pinion shaft housing, and bearings for supporting the pinion shaft withi pinion shaft housing work together to provide a continuous su...

A bearing lubrication system includes a stationary output shaft carrier housed within a gear housing wherein the output shaft resides partially within the carrier and upper and lower bearings support the shaft. The carrier includes first and second arcuately extending troughs for catching lubricating fluid slung by ...

ABSTRACT A planetary wheel drive uses: main bushings affixed to a rotatable housing between a stationary spindle permitting the rotatable output housing to rotate with respect to the stationary spindle, and, planet bushings affixed to rotatable planet gear between a planet pin permitting the planet gear to rotate w...

A planetary wheel drive uses a brake having a stamped spring plate which includes a plurality of spring stabilizer connections. Each one of the plurality of springs is mechanically bonded to a respective one of the plurality of spring stabilizer connections.  A brake piston includes a bore therethrough and resides i...

ABSTRACT A planetary wheel drive uses a single wall output planet carrier includes an internal spline fixed against rotation through an interconnection with an external spline of the stationary spindle. A locking lug of the single wall output planet carrier extends into a notch of a bearing nut. The locking lug pre...

ABSTRACT A planetary wheel drive uses a thrust washer residing between a cover and a thrust plate to absorb axial loads. The thrust washer is has a slip fit to the cover. The surface area of the thrust washer engaging the cover is larger than the surface area of the thrust washer engaging the thrust washer. Fig. 3...

A compact planetary wheel drive uses a high speed input planet carrier partially residing with a stationary spindle, and, an input planet gear engaging an internal ring gear within the stationary spindle. Inclusion of the input planet gear within the stationary spindle enables use of an additional stage of the plane...
