Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
78 words
In combination with rotary driving means, rotatably driven means, spherical bearing means journalling said driving and driven means for relative rotation and axial deflection of said driving means with respect to said driven means, the improvement comprising: a shaft drivably connecting said driving and driven means, said shaft being disposed through an opening in said bearing means wherein said shaft is axially deflectable with respect to both said driving and driven means in response to axial deflection therebetween.
Claim 2
Dependent Claim
78 words
In combination with rotary driving means, rotatably driven means, spherical bearing means journalling said driving and driven means for relative rotation and axial deflection of said driving means with respect to said driven means, the improvement comprising: a shaft drivably connecting said driving and driven means, said shaft being disposed through an opening in said bearing means wherein said shaft is axially deflectable with respect to both said driving and driven means in response to axial deflection therebetween.
Claim 3
Dependent Claim
26 words
The improvement defined in claim 1 wherein said shaft has a centerpoint and ends in axially deflectable engagement with said driving and said driven means, respectively.
Claim 4
Dependent Claim
55 words
The improvement defined in claim 2 wherein said bearing means is directly connected to and disposed between said driven and driving means in surrounding relation with said shaft such that a given deflection between said driving and driven means equals the sum of the deflections between said shaft ends and said driving and driven means.
Claim 5
Dependent Claim
41 words
The improvement defined in claim 3 wherein said bearing means comprises a spherical bearing having a centerpoint coincident with the centerpoint of said shaft whereby the deflections between respective said shaft ends and said driving and driven means are approximately equal.
Claim 6
Dependent Claim
47 words
The improvement defined in claim 4 wherein each of said shaft ends comprises an identical set of splines, said splines each having a centerpoint and being arcuate in lateral profile, and each set of splines meshes with respective toothed gears forming said driving and driven means, respectively.
Claim 7
Dependent Claim
26 words
The improvement defined in claim 5 wherein said shaft further includes a reduced diameter neck portion at each end thereof adjacent each said set of splines.
Claim 8
Dependent Claim
29 words
The improvement defined in claim 6 wherein the centerpoints of respective said set of arcuate splines are in linear alignment with, and equidistant from, said centerpoint of said shaft.
