Adjusting device for axial and radial piston machines

DETAILED DESCRIPTION The inventive adjusting device 1 is built onto the housing 2, which is shown in phantom lines, of an axial or radial piston pump.
The axial or radial piston pump evidences a phantom line-drawn lifting member 3 for a variation in the volumetric setting, whose position within the housing 2 is adjustable in the directions of the double-headed arrow 4 through the intermediary of the inventive adjusting device.
Hereby, the lifting member is provided with a protuberance 5 which engages into a recess 6 formed in an adjusting bifurcated member 7.
The bifurcated member 7 is in a portion of a follower 8 which is fastened on an adjusting nut 9.
The movement of the adjusting nut 9 in the directions of the double-headed arrow 4 and, accordingly, the displacement of the lifting member 3 is effectuated through the rotation of an adjusting spindle 10 which is in engagement with the adjusting nut 9.
An electric motor 11 which serves as a servomotor is in operative connection at the input side thereof with a planetary gear drive 12, which on the output side achieves the rotational movement of the adjusting spindle 10 through the overload protective coupling 13.
As illustrated, the inventive adjusting arrangement device consists of a housing 14 in which the adjusting spindle 10 is rotatably supported and sealed with respect to the outside.
In an extension of the axial direction of the adjusting spindle 10, there is detachably fastened on one side of the exterior of the housing 14 the electromotor 11, while on the opposite side of the housing 14, also in the axial direction of the adjusting spindle 10, there is detachably fastened the planetary gear drive 12, as well as the overload protective coupling 13.
For the transmission of the rotational movement of the electromotor 14 to the sun gear 15 of the planetary gear drive 12 there is provided an intermediate shaft 16 which passes coaxially through the adjusting spindle 10.
The intermediate shaft 16 is detachably connected with the power output trunnion 17 of the electromotor 11, as well as being detachably connected with the sun gear 15 of the planetary gear drive 12
