Gear reducerThe 5 major characteristics of transmission are as follows:
1. The ability to move smoothly, resist impact and vibration is strong due to the use of several wheels with the same structure, evenly distributed around the central wheel, which can balance the forces between the wheel and the rotating arm. At the same time, coaxial reducers also increase the number of teeth involved in meshing, so the motion of gear transmission is smooth, the ability to resist impact and vibration is strong, and the work is more reliable.
2. The transmission ratio is relatively large, which can achieve the synthesis and decomposition of motion. As long as the type of gear transmission and gear matching scheme are appropriately selected, a large transmission ratio can be obtained with a few gears. In gear reducers that only transmit motion, their transmission ratios can reach several thousand. It should be pointed out that gear transmission can still maintain many advantages such as compact structure, small mass, and small volume when its transmission ratio is large. Moreover, it can also achieve the synthesis and decomposition of motion, as well as complex movements with various variable speeds.
3. Gear reducers have small volume, small mass, compact structure, and high load-bearing capacity. Due to the power splitting and coaxial transmission of each central wheel in gear transmission, as well as the reasonable application of internal meshing gear pairs, their structure can be made very compact. Furthermore, due to the uniform distribution of several wheels around the central wheel to share the load, each gear bears a smaller load and allows for the use of smaller modules.
4. In addition, the coaxial reducer fully utilizes the high load-bearing capacity of the internal meshing and the capacity of the internal gear ring itself in terms of structure, which is conducive to reducing its external dimensions, making it small in volume, small in mass, very compact in structure, and has a high load-bearing capacity. Generally, the external dimensions and mass of gear transmission are about 1/2 to 1/5 of those of ordinary gear transmission (i.e. under the same load conditions).
5. The high transmission efficiency of gear reducers is due to the symmetry of the gear transmission structure, which has several evenly distributed wheels, allowing the reaction forces acting on the center wheel and the arm bearings to balance each other, thus facilitating the improvement of transmission efficiency. With appropriate selection of transmission type and reasonable structural arrangement, the efficiency value can reach 0.97-0.99.
