Abstract:
A hydraulic radial piston machine having a lifting ring (15) and having a cylinder block (18) which is arranged with respect to the lifting ring (15) in a manner allowing it to rotate about an axis of rotation (19) and has a multiplicity of cylinders (35) which are oriented in the radial direction of the cylinder block (18) and in each of which is accommodated a displaceable piston (45) which is supported on the lifting ring (15) via a roller (48), the roller (48) being mounted on the piston (45) rotatable about an axis of rotation (49) parallel to the axis of rotation (19) of the cylinder block (18) and being held axially in direction of said axis of rotation (49) in the cylinder (35) via individual roller guides (53) for the rollers of respective pistons, which roller guides are situated in front of its end sides (51, 52) and are torsionally secured with respect to the axis (36) of the cylinder (35) relative to the cylinder block (18), wherein at least one of the two roller guides (53) of a roller (48) is torsionally secured directly with respect to the cylinder block (18) without an additional part.
