| Abstract: |
| The designing technical difficulties are analyzed according to the technical requirements that make the rocket tank wall precision chemical milling lose weight. A set of special fold-style chemical milling rotating equipment is developed by defining brake machine, computing transmission ratio and linear velocity, releasing torque, and eliminating the gap of both side gears. The fold-style rotating chemical milling can reduce transmission gap while improve the rotating torque and machining precision, therefore it guarantees the requirements of precision chemical milling for the rocket tank wall. |
| Key words: rocket tank wall chemical milling fold-style totation transmission gap |
