Cycloid reducerThe advantages are:
1.Small size and light weight.Due to the wide use of planetary transmission structure, the structure is compact and comparable to ordinaryGear reductionCompared with the machine, the volume and weight can be reduced by 1/2 to 2/3.
2．传动比范围大。目前我国生产的单级传动比i＝6~87：二级传动比i＝99~5133；三级传动比可达i＝20339；根据需要还能达到更高。
3.High transmission efficiency.The efficiency of single-stage transmission can reach 0.9~0.
4.It runs smoothly, has no noise, and has a large overload capacity and strong impact resistance.Due to the large number of teeth meshing at the same time, in theory there are two-half of the teeth meshing, so there will be these superior performances.
5.Long service life. Because all contact parts are rolling friction, the service life is long. Compared with ordinary reducers, the service life is 2~3 times longer.
6.Simple structure
The shortcomings and shortcomings of the cycloid pinwheel reducer are as follows:
"Things are divided into two", this type of reducer currently has the following shortcomings:
1. Main parts such as cycloidal gear, pin tooth pin, pin tooth sleeve, pin and pin sleeve are all made of GCrl5 bearing steel with better material, and some parts require high manufacturing precision and the manufacturing process is complicated.
2.The swing arm bearing is subject to greater force and the speed is slightly higher than the speed of the high-speed shaft, so the swing arm bearing is the weak link of the reducer, which limits the speed and the transmitted power of the high-speed shaft; the speed of the general high-speed shaft is Nh1500~1800 R/min, the current power has exceeded 100 kilowatts.
However, with the deepening of people's understanding of it, as well as continuous improvement in technology and improvement of bearing performance, these shortcomings will gradually be overcome.
Cycloidal pinwheel reducers can replace ordinary two-stage and three-stage gear reducers and worm gear reducers in many cases, so they are valued by countries all over the world. my country began trial production in 1964, and there are already many factories in mass production. , And has been widely used in equipment in national defense, mining, metallurgy, chemical, textile and other industrial sectors.
The above content is the advantages and disadvantages of the cycloid pinwheel reducer, you can choose the appropriate reducer according to your actual situation.
