ABSTRACT:
An improved fluid pressure energy translating device of the axial piston type including a cylinder barrel mounted on a drive shaft. The cylinder barrel is centered on the drive shaft by a crowned bearing on the drive shaft and coupled through a splined connection which includes crowned male splines on the drive shaft. The crowned bearing and the crowned male splines on the drive shaft have centers located to either side to the center of bending of the drive shaft under load so as to eliminate tilting of the barrel.
