Gear

A gear, comprising:

• a plurality of segments arranged one behind another in a circumferential direction relative to an axis of rotation of the gear, each segment including a support region, a first flange region arranged at a front in the circumferential direction, and a second flange region arranged at a rear in the circumferential direction;
• wherein a first surface region of the first flange region of each segment lies against a second surface region of the second flange region of a next adjacent segment;
• wherein at least one screw passes through and connects the first flange region of each segment and the second flange region of the next adjacent segment;
• wherein the support region of each segment includes a helical toothing
• wherein the screw protrudes through the first surface region;
• wherein the first surface region extends parallel to a tooth of the toothing that is adjacent to the first surface region;
• wherein a first stepped bore is arranged the first surface region, the screw protruding through the stepped bore;
• and
• wherein a clear internal diameter of the first stepped bore increases monotonically with increasing distance from the first surface region.
