Figure 1 shows the variation trend of sliding rate with gear modulus in standard drives with the number of teeth (Z1=17, Z2=32), pressure angle (a=20 degrees), displacement coefficient (x1=x2=0) and crest height coefficient (ha*=1) unchanged.
As can be seen from Figure 1, with the increase of gear module, the theoretical engagement line of gear pair increases, the actual engagement line length also increases, and the bending degree of the slip rate curve changes, but the module does not affect the relative slip rate value at the engagement starting position.
Figure 2 shows the variation trend of sliding rate with gear indexing circle pressure angle in standard drives with unchanged number of teeth (Z1=17, Z2=32), modulus (m=6), displacement coefficient (x1=x2=0) and crest height coefficient (ha*=1).
As can be seen from Figure 2, with the increase of pressure angle, the slip rate of both wheels decreases except for the joint, and the bending degree of the slip rate curve decreases.
