Abstract
Gears, for example, for a gear train are disclosed. The gear may be divided into two axially adjacent spur gears and have a torsion spring in the form of a circular ring segment. Between two peripherally mutually opposing spring ends, a slot may be formed in which two cams engage which are each assigned to one of the two spur gears. One of the cams may be assigned to one of the two spring ends and the other cam may be assigned to the other spring end. The two cams may be arranged at least substantially overlap-free in an axial direction, wherein contact faces for the cams formed at both spring ends of the torsion spring are arranged on a radially outer end of the spring ends. The contact faces may be delimited radially inwardly by clearances on the spring ends.
