What are the advantages of gear reducer and ordinary cylindrical gear reducer?

Compared with cylindrical gear reducer transmission, gear reducer transmission has many unique advantages.Its most notable feature is that it can divide power when transmitting power; at the same time, its input shaft and output shaft are coaxial, that is, the output shaft and the input shaft are set on the same main axis.Therefore, gear reducer transmission has been used to replace ordinary gear transmission as a speed increaser and speed change device in various mechanical transmission systems.

  The main features of gear reducer transmission are as follows.

  1. Smooth movement, strong resistance to shock and vibration. Since several wheels with the same structure are used, they are evenly distributed around the center wheel, so that the sexual forces of the wheel and the rotating arm can be balanced with each other.At the same time, the coaxial reducer also increases the number of teeth involved in the meshing, so the gear transmission moves smoothly, has strong resistance to shock and vibration, and works more reliably.

  2. The transmission is relatively large, and the synthesis and decomposition of motion can be realized. As long as the type of gear transmission and the gear allocation scheme are appropriately selected, a few gears can be used to obtain a large transmission ratio.In the transmission of a gear reducer that is only used as a transmission motion, its transmission ratio can reach several thousand.It should be pointed out that the 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 realize the synthesis and decomposition of motions and the realization of complex motions with various variable speeds.

  3. The gear reducer is small in size, small in mass, compact in structure, and large in load capacity. Because the gear drive has a power split and a coaxial transmission of each center wheel and a reasonable application of internal gear pairs, it can make it very compact.Furthermore, several wheels are evenly distributed around the center wheel to share the load, so that the load on each gear is smaller, and these gears are allowed to adopt a smaller modulus.In addition, the coaxial reducer makes full use of the large internal meshing load-bearing capacity and the volume of the inner gear ring itself in the structure, which is conducive to reducing its outer profile size, making it small in size, small in mass, very compact in structure, and carrying capacity Big.Generally, the outer profile size and quality of gear transmission is about 1/2 to 1/5 of that of ordinary gear transmission (that is, under the same load condition).
