In a gear, we measure various parameters such as pitch diameter, tooth thickness, backlash, and runout.

• Pitch diameter is measured using a gear measuring machine or by calculating it from the number of teeth and the module or diametral pitch.

• Tooth thickness is measured using a gear tooth vernier caliper or a gear tooth micrometer.

• Backlash is measured by placing a dial indicator on the gear teeth and measuring the moveme...read more
