摘要

The gear transmission has two intermeshing spur gears (1,2) with helical teeth (3,4), where the former spur gear has a ring (6) arranged in the region of the tooth width. The latter spur gear has an annular groove (7), into which the ring is positively engaged. The ring is formed as a spiral ring with a winding. The ring height is approximately equal to the tooth height.
