Bevel gear testing machines are special machines used to check the quality and accuracy of bevel gears. Bevel gears are cylindrical gears used in various machines and applications, especially in transmissions and differentials of vehicles. Bevel gear testing machines can perform various tests to ensure that bevel gears meet the required specifications. These include: Measuring tooth thickness: the machine can measure tooth thickness at various points on the gear to ensure it is within tolerance limits. Checking the tooth flanks: The machine can check the surface quality and contact point of the tooth flanks to ensure that they are correctly shaped and in the correct position. Measurement of tooth backlash: The machine can measure the tooth backlash between two bevel gears to ensure that it is within the tolerance limits. Determination of head and root roundness: The machine can measure the tip and root roundness of the bevel gear to ensure it is within tolerance limits. Bevel gear inspection machines are usually computer-controlled and can perform high-precision measurements. They are essential for quality assurance of bevel gears and help to ensure that they meet the required specifications and function without defects.
