(2) the existence of the tooth space, in order to guarantee normal mesh between gear and transmission is smooth, smooth, watches and clocks are mostly using modified cycloid tooth shape, tooth tooth Angle and the tooth Angle, also must have a backlash, otherwise you will
, the phenomenon of the top teeth or shave tooth. A pair of gears tooth space is very small, but to become number of the gear, the tooth space superposition together, it becomes obvious. Passes through a tiny empty corner, the pointer will be behind the push, this to
