Technical Field

[0001] This utility model relates to the field of double gear technology, specifically a high-strength forged double gear. Background Technology

[0002] A gear is a mechanical component with teeth on its rim that can continuously mesh to transmit motion and power. There are many types of gears, including double gears. Double gears are transmission components composed of two gears combined into one unit, mainly used in the gear train of a transmission to change the rotational speed or velocity of the output shaft.

[0003] However, existing double gear systems have the following problems during use: some of the two gears in a double gear system are fixed together and cannot be disassembled. When one gear is damaged, the entire double gear system often becomes unusable. There is a lack of a structure for maintaining and disassembling the double gear system, which requires fixing during use, increasing the cost of scrapping it. Therefore, it is necessary to design corresponding technical solutions to address these problems. Utility Model Content
