Since the teeth 23 formed on the cylindrical surface 22 are continuous with the ends of the teeth 25 formed on the paper surface 24, the teeth 23 on the cylindrical surface 22 are formed.
The spur gear 34 meshing with the teeth 23 can also mesh with the tooth width region of the teeth 25 on the tapered surface 24 beyond the original tooth width of the teeth 23. That is, as shown in FIG.
The line of intersection between the teeth 25 of the tapered surface 24 and L
When the point of intersection of P with the pitch line PL of the teeth 23 of the cylindrical surface 22 is P, the maximum tooth width W of the spur gear 34 that can mesh with this gear X
max is the original tooth width W 1 of the teeth 23 of the cylindrical surface 22, the width W 2 to an intersection P in the region of the tooth width of the teeth 25 of the tapered surface 24
Is added. As described above, the spur gear 34 meshes with not only the teeth 23 of the cylindrical surface 22 but also the teeth 25 of the tapered surface 24, and a part of the meshed teeth 25 of the tapered surface 24 functions as the teeth of the cylindrical surface. If the tooth width of the meshing spur gear 34 is the same, the tooth width of the teeth 23 of the cylindrical surface 22 of the gear X is reduced, that is, the axial length of the gear X is reduced to reduce the size of the gear transmission. Can be planned.

Also formed on tapered surface
Since the set teeth and the teeth formed on the cylindrical surface are continuous, the spur gear meshing with the teeth on the cylindrical surface also meshes with the tooth width region of the teeth on the tapered surface beyond the original tooth width of the teeth. Can be
Since a part of the teeth of the meshed tapered surface functions as the teeth of the cylindrical surface, if the tooth width of the meshing spur gear is the same, the tooth width of the teeth of the cylindrical surface of the gear is reduced, that is, the gear shaft is rotated. By forming the length in the direction short, the size of the gear transmission can be reduced. Also, since the phases of both consecutive teeth are the same ,
Variations in accuracy due to assembly of the gear transmission can be extremely reduced.
