Abstract
One end of a rotatable mixer drum is journalled by a spherical bearing mounted on the housing of a power transmission having its rotary output coupled to the drum by a drive shaft which axially penetrates the bearing. Arcuate splines at opposite ends of the drive shaft mesh with gear teeth of the transmission output gearing and with gear teeth carried by the drum whereby the shaft is free to deflect with respect to the transmission gearing and the drum gearing when the spherical bearing deflects as a result of drum-to-transmission misalignment. The shaft is arranged with respect to the bearing and the gear teeth engaged by its splines so that the total deflection of the bearing is divided between the ends of the shaft.
Claims3
A vehicular mixer comprising:
- a vehicle, a motor driven torque transmission mounted on said vehicle, a mixer drum having one end rotatably journalled on said vehicle and the other end journalled by a spherical bearing for relative rotation and axial deflection with respect to said transmission;
- said transmission having a driving gear in axial alignment with a driven gear of said drum;
- a rotary drive shaft extending through said spherical bearing for coupling driving torque from said transmission to said drum and having sets of splines at opposite ends in meshing engagement with said driving and driven gears.
