(1) design feature
A) low noise design
Gear adopts optimizes profile of tooth, by using non-standard profile of tooth, increases the profile of tooth height, thereby increases the gear pair contact ratio, greatly reduces the noise of speed changer and prolongs the gear life (see figure 2).
B) preceding odd-side is often nibbled wheel hypervelocity device, and big number of teeth driving wheel of Involute Gear Pair and the engagement of little number of teeth driven wheel realize system's raising speed.(see figure 3)
C) this uses the Specifeca tion speeification of new work transmission assembly
Maximum input torque: 2000Nm
The highest input speed: 2600rpm
