Apparatus for the lapping or testing of gears

An apparatus for the lapping or testing of gears, comprising:

• at least five axes, said at least five axes including
• a first axis of rotation, wherein the apparatus includes a first spindle group for chucking a first gear, whereby the first gear is mountable on the first spindle group so that it is rotatable about the first axis of rotation;
• a second axis of rotation, wherein the apparatus includes a second spindle group for chucking a second gear, whereby the second gear is mountable on the second spindle group so that it is rotatable about the second axis of rotation;
• two linear axes configured to perform linear displacements of the first spindle group with the first gear relative to the second spindle group with the second gear, said two linear axes defined by
• a first linear axis oriented to perform a first linear displacement of the first spindle group with the first gear relative to the second spindle group with the second gear;
• and
• a second linear axis oriented to perform a second linear displacement of the first spindle group with the first gear relative to the second spindle group with the second gear;
• and
• one or more of:
• a first swivel axis oriented to perform pivoting of the first spindle group with the first gear thereabout, wherein said first swivel axis is parallel to the second axis of rotation;
• or
• a second swivel axis oriented to perform pivoting of the second spindle group with the second gear thereabout, wherein said second swivel axis is parallel to the first axis of rotation.
