The basic transmission structure of planetary reducer: It is mainly composed of four parts: sun gear, planetary gear, internal gear ring, and stage gear. The planetary gear is used to achieve power splitting and multi-tooth meshing. The planetary reducer has the characteristics of high rigidity, low backlash, high efficiency, high torque, low pulsation, multiple working conditions, and lifetime maintenance-free. Because of these characteristics, planetary reducers are mostly installed on stepper motors and servo motors to reduce speed, increase torque, and match inertia.
Features of planetary reducer:
1. Precise straight tooth manufacturing, small size, compact structure, high precision, ensuring long life and low noise.
2. Fully sealed structure to ensure that the lubricating grease does not leak and is maintenance-free.
3. The products have passed the efficiency test system, and the transmission efficiency is above 96%.
4. High-precision design, ultra-low backlash can achieve 3 arc minutes.
5. The product is highly substitutable, and the overall dimensions completely replace the same type of series products, and can be matched with high-precision servo motors.
Gears are divided into straight teeth and helical teeth. The main difference is that the precision of straight teeth is high, and the reversal sound of helical teeth is noisy.
In terms of the structure of the
planetary gearbox, the planet carrier of the helical gear planetary reducer must be supported by a double support structure, while the planet carrier of the spur gear planetary reducer can be used as a single support or a double support. It's just that the single support of a spur gear is far inferior to the double support of a spur gear in terms of accuracy, noise, and efficiency. Compared with the helical gear planetary reducer, the double-support spur gear planetary reducer has higher precision than the spur gear, so the precision of the helical planetary reducer will be higher.
