Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a sun gear tooth surface detection device. Background Art

[0002] The sun gear is the basic component of the epicyclic gear train. In the planetary gear train, the external gear that serves as the central gear, and in the planetary gear transmission, the external gear and internal gear on the same axis as the planet carrier are called the sun gear. The sun gear and the planet carrier are generally used as input and output components, so they are also called the basic components of the epicyclic gear train. The basic components all revolve around the same fixed axis.

[0003] After the sun gear is produced, it is usually necessary to test the accuracy and quality of the sun gear tooth surface. Currently, the sun gear is placed in a storage box containing an etchant, and then the sun gear tooth surface is etched with the etchant. After the etchant is treated, the operator takes out the sun gear with an external tool, and then observes the color change of the sun gear tooth surface, and finally determines whether it has defects such as grinding burns.

[0004] During the inspection of the sun gear tooth surface, the operator uses external tools to remove the sun gear after the acid etching treatment. However, the operation is cumbersome. If the operation is improper, the acid etching agent may cause harm to the operator. Some sun gear tooth surface inspection devices use a robot to clamp and fix the sun gear, and then immerse the sun gear in the acid etching agent, so that the tooth surface of the sun gear is acid-etched by the acid etching agent. Although this method can prevent the operator from being injured, the cost is relatively high. Although it can be passed, for this reason, we propose a sun gear tooth surface inspection device.
