The difference in structure is that the single support has three pin holes on the planet carrier, put three pins, and then fix the gears on the pins. One side of the gear is the planet carrier, and the other side is suspended, and a block is placed behind it. separate.The double-supported planet carrier is hollowed out by CNC, and then the pin holes are punched in the upper machining center. It must also be ensured that the pin holes on the upper and lower sides are completely concentric (otherwise the gears will not mesh with the gears), and then the gears are put in. Finally, it is fixed with pins, and both sides of the gear are supported by the planet carrier.The difference in force The single support structure is that the gears on the planet carrier are only stressed on one side, and the double support structure is that the gears on the planet carrier are stressed on both sides.3. The difference in performance The single-supported gear will be biased 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. If it rises, it will even lead to oil leakage.in addition Read More

Compared with cylindrical gear reducer transmission, gear reducer transmission has many unique advantages.Its most notable feature is that it can perform power splitting when transmitting power; at the same time, its input shaft and output shaft are coaxial, that is, the output shaft and input shaft are set on the same main axis.Therefore, gear reducer transmission has been used by people to replace ordinary gear transmission, and as a speed increaser and speed change device in various mechanical transmission systems.The main characteristics of gear reducer transmission are as follows.1. Smooth movement, strong shock and vibration resistance. Several wheels with the same structure are evenly distributed around the center wheel, so that the forces of the wheels and the rotating arm can be balanced with each other.At the same time, the coaxial reducer also increases the number of teeth participating in the meshing, so the movement of the gear transmission is stable, the ability to resist shock and vibration is strong, and the work is more reliable.2. The transmission is relatively large, and the synthesis and decomposition of motion can be realized as long as the type of gear transmission is properly selected. Read More
