    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: 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 overload of the gearbox transmission, the input shaft fractures an annular groove in the input shaft. A bushing prevents travel of the portion of the input shaft which is driven by the prime mover and which continues to spin after the fracture.

    摘要: Lubricating oil is forced and pumped into and through the first passageway through the floating ring gear and into the annulus between the gearbox housing and the floating ring gear. Lubricating oil from the annulus is pumped into and through the second passageway and through the joint between the second and third passageway, and through the third passageway into the void in the cover. Thereafter the oil passes through the fourth passageway between the void in the cover and the circumferential recess in the cover and lubricating the bearing mounted adjacent the recess in the cover/housing.

    摘要: A double clutch arrangement for use in a transmission or other place where mechanical clutch is desired that has a high torque capacity and small engagement and disengagement forces at the shift lever. The clutch arrrangement is utilized on the output shaft of a two-position clutch having forward and reverse gears and includes a ball screw actuated clutch mechanism positioned between the shaft and an externally actuated encompassing shift collar in combination with a friction clutch mechanism. The friction clutch mechanism comprises either a pair of clutch friction packs positioned between the shift collar and the forward and reverse gears or a pair of cone clutches therebetween. Initial actuation of the forward or reverse friction pack or cone clutch will initiate the ball screw clutch mechanism to lock up the clutch in either direction.
