Abstract: Point-line meshing gear is a new kind of gear transmission.
The selections of parameters between point-line meshing gear and
involuted gear are different while designed. The closed picture of
involuted gear can not be applied to that of the point-line meshing
gear. The closed picture of point-line meshing gear relates to the
number of teeth z1, z2 and the tool parameters, but it doesn't relate to
center distance a and modul-
us mn. The
big gear's coefficient factor x2 and helix angle b are chiefly decided
by the closed picture, and other parameters are accordingly decided
then. It illustrates the meanings of curves of the closed picture. It
also illustrates that by designing different x2 and β the bears with
different tooth profile, meshing angles, whole depths as well as the
characters of meshing etc will be got. It also mentions the
characteristics of point-line meshing gear and the abnormal graphs as
well as their characteristics while choosing different tool’s parameters
with the sameness z1 and z2.
