Description

Technical Field

[0001] The utility model relates to the technical field of differential processing, in particular to a high-efficiency gooseneck tool specially used for the inner cavity of an automobile differential. Background Art

[0002] The differential balances the speed difference between the wheels on both sides through the rotation and revolution of the planetary gears. When the vehicle turns, the outer wheels need to travel a longer distance, so their speed will be faster than the inner wheels. The differential allows the outer wheels to obtain more power through the rotation of the planetary gears, thereby maintaining the stability and controllability of the vehicle.

[0003] A planetary carrier differential is a device that integrates a planetary carrier into a differential, aiming to improve transmission efficiency and load-bearing capacity while reducing size and weight. This structure is widely used in automobiles, construction machinery, industrial equipment and other occasions that require precision transmission and high torque transmission. In particular, in the field of battery electric vehicles (BEVs), this differential design helps to improve driving range and overall performance.

[0004] The thrust surface diameter of the planetary carrier's differential case is relatively large, and the diameter of the cutting edge is relatively small. The traditional processing method uses a machining center to insert the tool rod into the workpiece, manually install the cutter head, and then process the thrust surface. After processing, the cutter head is manually disassembled. This practice not only reduces processing efficiency, but also poses certain risks in the process of repeatedly disassembling the cutter head.

[0005] Therefore, a high-efficiency gooseneck cutter specially designed for the inner cavity of automobile differential is proposed. Utility Model Content
