Customers often consult Xiaobian: What do you mean by double support of planetary reducer and single support of planetary reducer? Today, Xiaobian will explain the double support of planetary reducer and the single support of planetary reducer.

1. Meaning of double support of planetary reducer and single support of planetary reducer Double support of planetary reducer and single support of planetary reducer refer to the support of gears, that is, the planet carrier of planetary reducer. Single support structure means that only one side of the gear on the planet carrier is stressed, while double support structure means that both sides of the gear on the planet carrier are stressed. 2. Double support performance of planetary reducer and single support performance of planetary reducer Double-support servo planetary reducer has two supporting points, and its bearing and planet carrier are integrated. Each pin hole must correspond up and down, and must be accurate, and must be completely concentric without any deviation. The gears on the planet carrier are stressed on both sides, which ensures the stability and accuracy of the planetary reducer, and will not run off even when it is subjected to great torsion. However, the single support has only one support point, and the gears on the planet carrier are stressed on only one side. When the reducer with single support is stressed, the gears will deflect to the other side. After a long time, it will appear, and the noise will increase, the gears will be deformed, the wear will be accelerated, and the service life will be shortened. When the output shaft of the planetary reducer is loaded for transmission, the gears of the single-support planetary reducer will deviate in the opposite direction of the output shaft transmission, so that the friction coefficient between the planetary gear and the planetary inner gear ring will increase, but the result will lead to the noise increase, the efficiency decrease, the temperature increase and even the serious oil leakage. In addition, planetary reducer is mainly used with servo motor. As we all know, servo motor is characterized by small size, high precision and frequent forward and reverse rotation. When single-support planetary reducer is used with servo motor in frequent forward and reverse rotation, the gear pin on the planet carrier of single-support planetary reducer is easy to produce rigid deformation, which will lead to larger clearance of single-support planetary reducer. 3. The cost of double support and single support of planetary reducer The planet carrier of the planetary reducer and the output shaft of the planetary reducer are integrated structures, so whether the planet carrier of the planetary reducer is well done directly affects the performance of the planetary reducer in all aspects. The planet carrier of the planetary reducer with double/single support and the output shaft of the planetary reducer are all integrated structures. Only three gear pin holes need to be punched on the planet carrier with single support. However, before punching the gear pin hole, the double-support planet carrier needs to empty the center of the planet carrier with CNC, and then punch holes in the machining center, where the double-support structure needs one more process than the single-support structure in the same industry. Single-support planet carrier only needs to punch holes on one surface, so to speak, it will not be scrapped even if it is missed, and it can be played at a 30 angle. To put it mildly, this planet carrier is inside the product, and who knows how many holes have been punched, and it will not have any adverse effects on the product. And the double support structure is completely different. First, empty the middle of the planet carrier with CNC, and then punch holes in the upper machining center. It is also necessary to ensure that the pin holes on the upper and lower surfaces are completely concentric. Everyone knows that the difficulty of punching holes on one surface to ensure concentricity is completely different from that of punching holes on two surfaces at the same time. Once the holes are offset, the whole planet carrier will be scrapped. Therefore, the material cost of the planet carrier, especially the processing cost, is about 20% more than the cost of the whole machine.
