Custom Gear Production Case Study: Small Module Bevel Gears for the Robotics Industry

Install the backlash very small to improve positional accuracy and reduce damage to the tooth surfaces!

This is a small module bevel gear used in robot joints. The material is SCM, and it has been subjected to carburizing heat treatment. The positional accuracy of a robot arm is greatly influenced by the quality of the gears. In conventional products, the machining accuracy of the gears was poor, leading to unstable backlash. The customer aimed to significantly reduce backlash by performing grinding on the tooth surfaces, thereby improving positional accuracy and reducing damage to the tooth surfaces. They consulted various companies but could not find a supplier capable of grinding the tooth surfaces of these small-pitch bevel gears, which left the customer very troubled. Thus, they reached out to our company, and this became a case we handled. We reviewed the tooth surface design and selected the optimal tools. Furthermore, we purchased a special processing machine capable of high-speed rotation from overseas, creating an environment where prototypes could be produced. As a result, we successfully manufactured small-pitch bevel gears that matched the customer's requirements. Our company is committed to exploring various methods to address challenging projects that other companies may decline, just like in this case. If you have any issues related to gears, please feel free to consult with OJIC.
