Axial piston machine having integral counting perforation

An inclined-axis axial piston machine comprising:

• a housing;
• a drive shaft mounted in the housing so as to rotate about a first axis of rotation;
• a cylinder barrel having a second axis of rotation with a position that is settable or fixed such that the second axis of rotation intersects the first axis of rotation at an angle other than zero, the drive shaft being connected to the cylinder barrel so as to rotationally drive the cylinder barrel;
• a flange that is integral with the drive shaft;
• a plurality of pistons arranged in the cylinder barrel in a linearly movable manner substantially along the second axis of rotation, each piston of the plurality of pistons being coupled to the flange via a ball joint;
• a multiplicity of counting perforations arranged in a periodically distributed and continuous manner over an outer circumferential surface of the flange;
• a sensor accommodated in the housing and arranged opposite the counting perforations such that rotation of the drive shaft causes a signal change at the sensor,
• wherein each counting perforation is formed integrally from the flange as a recess, each recess having a single continuous perimeter and a side wall that extends uninterrupted around an entire circumference of the perimeter so as to form a smooth and continuous side wall surface extending around the entire circumference of the perimeter, and
• wherein the recesses are defined by a bottom surface that has flat sections, the flat sections being arranged in an inclined manner relative to each other.

• wherein a third section of the side wall and a fourth section of the side wall are each formed as half of a circular cylinder having a central axis of that intersects the first axis of rotation, the first, second, third and fourth section of the side wall arranged such that, taken together, the first, second, third, and fourth sections form the side wall as a continuous wall.
