Introduction to the measurement methods of backlash.
Backlash refers to the intentional gap created between gears. If there is no gap between the gears, the transmission of rotational motion becomes poor, and further wear between the gears can lead to their deterioration. In other words, the presence of this backlash allows the gears to perform rotational motion smoothly. However, it is not enough for this backlash to simply exist; it is important that it is of an appropriate size. - In the case of spur gears and helical gears: For spur gears and helical gears, backlash refers to the gap or play on the pitch circle of a pair of meshing gears. The size of this backlash can be determined according to the JIS accuracy grade. The sum of the minimum values calculated from the face module (size of the gear) and the pitch circle diameter of a pair of gears is defined as the minimum backlash, while the sum of the maximum values is defined as the maximum backlash. Depending on the intended use of the gears, values for backlash can be adopted that differ from the accuracy grades. ↓↓ Click here for the measurement method of bevel gears ↓↓

Gear Meshing Test Machine T60A (KLINGELNBERG) This gear meshing transmission error test machine (T60A) is designed for testing the meshing of bevel gears and hypoid gears. There are few units available in Japan, and according to OJIC's research, there are only a handful of such devices in the country. It is capable of measuring meshing transmission errors under torque and can verify tooth contact and meshing transmission errors in conditions close to actual operation.
