Cog wheel, or chain wheel - has toothed sections with cavities parallel to wheel axis, and teeth

摘要

The cog wheel (1), especially chain wheel consists of several toothed sections in the rotational direction. They are formed of cavities (7) in the material of the cog wheel. The cavities (7) are parallel to the cog-wheel axis of rotation and symmetry (11). The number of cavities (7) equals that of the teeth (3). The cavities (7) open into the spaces (9) between the teeth. USE/ADVANTAGE - The cog wheel can withstand considerably greater force, is harder-wearing and runs quietly.
