Which is Faster, 16-tooth or 18-tooth Gear?

[DelAdelyn]

16-tooth is faster. When the motor-side gears are of the same size, the smaller gear on the shaft will be faster. Under normal circumstances, the 16-tooth gear should be faster, while the 18-tooth gear provides more torque. Below is relevant information about gear backlash: 1. Introduction: Gear backlash refers to the circumferential play of one gear when the other gear in an assembled gear pair is fixed, measured as the arc length on the pitch circle. In the transmission of rotating mechanisms, the pinion gear is installed with the rotary bearing as a standard component, and its tooth thickness cannot be altered. To meet the requirements of the gear bearing heavy loads, the thickness of the pinion gear cannot be reduced. 2. Design Principle: To ensure the formation of a proper lubricating oil film between tooth surfaces and to prevent the gears from jamming due to thermal expansion deformation caused by increased operating temperatures, appropriate gear backlash must be maintained during meshing.
