The reason for the use of helical gears in the manufacture of planetary reducers: The main defect of spur gears is vibration. Especially the interlocking of the slow-drive motor and the main motor, the oil station oil pump motor and the main motor, and other interlocks required by the basic unit diagram. Check the connection of the slow drive to ensure that the rear is connected. After connecting it to the reducer with the handle, move the slow drive by hand to confirm the operation.
After running, the motor can start at low speed without jamming and impact. Since at any time, about half of the time (assuming the coincidence degree is 1.5), the two teeth will mesh, which brings additional benefits in terms of strength. Check whether the anchor bolts of the entire system of the planetary reducer and all the connecting bolts can be tightened, and check whether the entire control system is intact and reliable.
Whether due to design, manufacturing or deformation, the involute tooth profile may change along the entire tooth surface at the same time. After refueling for 30 minutes, check that the piping system connection flange, oil pressure, oil temperature and various systems are operating normally. Start the main motor to run the helical gear of the reducer, unlike a straight wheel, which will cause poor axial force.
This will incur a regular, once per tooth encouragement, usually very intense. Therefore, helical gears should be used in the manufacture of reducers instead of spur gears. The resulting vibration will bring heavy load and noise to the gear. Another drawback is that sometimes two pairs of teeth are joined during the contact process. Since the stress is limited by the joining conditions of one tooth during the cycle, additional strength cannot be used.
