The single support has three pin holes on the planet carrier, put three pins, and then fix the gear on the pin. One side of the gear is the planet carrier, the other side is suspended, and a baffle is placed at the back to separate it. The double-supported planet carrier is emptied by CNC, and then上加工中心打销子孔。
It is also necessary to ensure that the pin holes on the upper and lower sides are completely concentric (otherwise the gear and the gear will not mesh), and then put the gear in and fix it with a pin. Both sides of the gear are supported by the planet carrier. The difference in force The single support structure is that only one side of the gear on the planet carrier is subjected to force.
The dual support structure is the force on both ends of the gears on the planet carrier. The difference in function of the single-supported gear will be in the opposite direction of the output shaft transmission, and the friction coefficient between the planetary gear and the planetary ring gear will increase. As a result, the noise of the planetary reducer will increase, the efficiency will decrease, and the temperature will increase. , And even serious oil leakage will result.
Other planetary reducers are mainly used to cooperate with servo motors, and the characteristics of servo motors are small size, high precision, and frequent positive rotation. When single-support planetary reducers are used with servo motors, single-support planetary The gear pin on the planet carrier of the reducer is simply rigidly deformed, so it will cause the gap of the single-support planetary reducer to become larger
