Basic Gear Terminology and Calculation | KHK
Backlash is a play between tooth surfaces of paired gears in mesh. Mating gears also have a clearance (play) vertical to tooth depth. This is called Tip and Root Clearance (c), the distance between tooth root and the tooth tip of mating gears.
What is backlash and tip clearance in gear？
Consult the gear manufacturer's specifications to determine the required amount of backlash. Step 3: Adjust the gears – To increase the backlash, move the gears further apart. This can be done by loosening the mounting bolts and shifting the gears to the desired position. To decrease the backlash, move the gears closer together.
