度を与えることによって、作り出すことができる。For the manufacture of metal members for motion transmission of toothed transmissions,
It is necessary to use a &)tA and alloy with sufficient hardness, since with that hardness the toothed 4.1 gearing is subjected to mechanical stresses of a magnitude. For such motion transmission members of the gear or rack type,
It is desirable to use special steel or treated steel (φ), but this is relatively expensive and even more expensive.The present invention overcomes these drawbacks by using a new production method. According to this method, these transmission members are transformed from mere sort-like bodies that do not have a high degree of mechanical properties to the area where the teeth of the member are to be cut into other areas. It can be created by giving it a higher hardness than the hardness of 4.
