Helical planetary gear and internal helical gear for a helical planetary gear unit as well as helical planetary gear unit for an adjusting device for adjusting two components which are adjustable with respect to one another

An internal helical gear for a helical planetary gear unit for an adjusting device for adjusting two components which are adjustable with respect to one another, comprising:

• an internal helical gear axis defined by the helical gear;
• an inner toothing having a first inner toothing end and a second inner toothing end, wherein the first inner toothing end and the second inner toothing end are arranged apart from one another in relation to the internal helical gear axis;
• and
• wherein the inner toothing has a diameter that increases or decreases proceeding from the first inner toothing end to the second inner toothing end.

A helical planetary gear unit for an adjusting device for adjusting two components which are adjustable with respect to one another, comprising:

• a helical gear shaft with a helical gear shaft axis, the helical gear shaft comprising helical gear toothing, wherein the helical gear shaft is mounted so as to rotate about the helical gear shaft axis;
• a planetary carrier with at least one helical planetary gear, the planetary gear comprising:
• a planetary gear axis defined by the planetary gear;
• a planetary gear toothing having a first planetary gear toothing end and a second planetary gear toothing end, wherein the first planetary gear toothing end and the second planetary gear toothing end are arranged apart from one another in relation to the planetary gear axis;
• and
• wherein the planetary gear toothing has a diameter that increases or decreases proceeding from the first planetary gear toothing end to the second planetary gear toothing end;
• wherein the helical planetary gear is mounted so as to rotate about the planetary gear axis in the planetary carrier;
• wherein the planetary gear axis extends skewed with respect to the helical gear shaft axis and the planetary gear toothing is meshed with the helical gear toothing;
• and
• an internal helical gear comprising:
• an internal helical gear axis defined by the helical gear;
• an inner toothing having a first inner toothing end and a second inner toothing end, wherein the first inner toothing end and the second inner toothing end are arranged apart from one another in relation to the internal helical gear axis;
• and
• wherein the inner toothing has a diameter that increases or decreases proceeding from the first inner toothing end to the second inner toothing end;
• and
• wherein the inner toothing is meshed with the planetary gear toothing.
