Planetary gear recer is also known as planetary recer, gear recer. In the recer family, planetary gear recer with its small size, high transmission efficiency, wide deceleration range, high precision, long life and many other advantages, is widely used in automobile drive, communication antenna electric adjustment system, precision medical equipment, smart home and other fields

The main structure of planetary gear recer is composed of planetary gear, sun gear, inner ring gear, transmission shaft and drive motor; Because of the structure of planetary gear recer, the single-stage rection is 3, generally not more than 10, the common rection ratio is 3 / 4 / 5 / 6 / 8 / 10, and the number of recer stages is generally not more than 3, but some customized recers with large rection ratio have 4-stage rection. Compared with other recers, planetary gear recers have the characteristics of high rigidity, high precision (single stage can achieve less than 1 point), high transmission efficiency (single stage is 97% - 98%), high torque / volume ratio, life-long maintenance free, etc

Because a set of planetary gears can not meet the larger transmission ratio, sometimes two or three sets are needed to meet the requirements of larger transmission ratio. Because the number of planetary gears is increased, the length of two or three-stage recer will increase and the efficiency will decrease.
return clearance: fix the output end and rotate the input end clockwise and counterclockwise, When the rated torque + - 2% is generated at the input end, there is a small angular displacement at the input end of the recer, which is the return clearance; Points & quot;, It's also called back gap.

uses: car driver, communication antenna equipment, medical equipment, electronic procts, household appliances, intelligent home equipment, intelligent kitchen and bathroom equipment, intelligent wearable equipment, massage and health care equipment, security equipment, optical equipment, photography equipment, home audio-visual equipment, intelligent office equipment, robot equipment Instrial automation equipment, etc

3. The standard name of planetary recer and planetary gear recer is planetary recer. The main structure of planetary recer is planetary gear, which is used to realize the effect of power split and multi tooth meshing. Planetary recers have the characteristics of high rigidity, high precision (single stage can be less than 1 point), high transmission efficiency (single stage can be 97% - 98%), high torque / volume ratio, life-long maintenance free and so on. Because of these characteristics, most planetary recers are installed on stepper motor and servo motor to rece speed and improve torque, Compared with planetary recer, gear recer has lower precision and transmission efficiency, and its price is much lower

The difference between planetary recer and gear recer is: different working principle, different structure and different use

The working principle of planetary recer is that when the power on the input side drives the sun gear, it can drive the planetary gear to rotate and revolve along the center according to the track of the inner gear ring. The rotation of the traveling star drives the output shaft connected to the tray to output power

2. Gear recer: the working principle of the gear recer is that it is tensioned by the pull pin mechanism, and there is a gear driven by external power in the center of the ring gear, which carries out independent closed transmission according to the mole design principle

Planetary recer: the main transmission structure of planetary recer is planetary gear, sun gear and inner ring gear

Three, different uses

1, planetary recer: planetary recer can be used as supporting parts for lifting, mining, transportation, construction and other instries

Gear recer: gear recer is widely used in large mines, steel, chemical instry, port, environmental protection and other fields

the advantages of planetary recer are small volume, light weight, high bearing capacity, long service life, stable operation, low noise, large output torque, large speed ratio, high efficiency and safe performance

The disadvantage of planetary recer is that it has high cost and maintenance because of its material precision and meticulous processing method

The advantage of gear recer is that it doesn't need cooling; Using maintenance free grease lubrication, long life and silent operation, high output efficiency; The shell is made of alloy steel, with high coaxiality and dynamic balance, and can be installed on various machining centers

The disadvantage of gear recer is high rigidity and high precision design, which leads to high maintenance cost. The precision and torque are lower than planetary recer

5. Planetary gear recer: the main transmission structure is planetary gear, sun gear and outer ring gear. Because of the structure of planetary gear recer, the minimum single-stage rection is 3, the maximum is generally not more than 10, the common rection ratio is 3.4.5.6.8.10, and the number of recer stages is generally not more than 3, but some customized recers with large rection ratio have 4-stage rection, Because of these characteristics, planetary recers are mostly installed on stepper motor and servo motor to rece speed, improve torque and match inertia. The maximum rated input speed of the recer can reach 18000rpm (related to the size of the recer, the larger the recer is, the higher the speed is), The smaller the rated input speed is), the output torque of instrial planetary recer is generally not more than 2000Nm, and that of special super large torque planetary recer is more than 10000nm. The working temperature is generally about - 25 ℃ to 100 ℃, The working temperature of planetary gear recer can be changed by changing the grease. Several concepts about planetary gear recer are as follows: stage: the number of planetary gear sets. Because a set of star gear can not meet the larger transmission ratio, sometimes two or three sets are needed to meet the requirements of larger transmission ratio. Because the number of star gear is increased, the length of two or three-stage recer will be increased, Return clearance: when the output end is fixed and the input end rotates clockwise and anticlockwise to proce the rated torque + - 2% at the input end, there is a small angular displacement at the input end of the recer, which is the return clearance. The unit is & quot; Points & quot;, Planetary cycloid pin gear recer: all transmission devices can be divided into three parts: input part, deceleration part and output part. The input shaft is equipped with a 180 mm offset screw ° The eccentric sleeve is equipped with two roller bearings called the rotating arm to form the H mechanism. The center holes of the two cycloid wheels are the raceways of the rotating arm bearings on the eccentric sleeve, and the cycloid wheel is meshed with a group of ring arranged needle teeth on the needle gear to form an internal meshing rection mechanism with tooth difference as one tooth, The needle tooth is provided with a needle tooth sleeve. When the input shaft rotates with the eccentric sleeve for one cycle, the cycloid gear's motion becomes a plane motion with both revolution and rotation e to the characteristics of the tooth profile curve on the cycloid gear and its limitation by the needle teeth on the needle gear. When the input shaft rotates in the positive direction, the eccentric sleeve also rotates for one cycle, and the cycloid gear rotates one tooth in the opposite direction to get deceleration. Then, with the help of W output mechanism, the cycloid gear can rotate one tooth in the opposite direction, The low-speed rotation of cycloid wheel is transmitted to the output shaft through the pin shaft, so as to obtain a lower output speed. The cycloid pin gear recer features high speed ratio and high efficiency single-stage transmission, which can achieve a rection ratio of 1:87, with an efficiency of more than 90%. If multi-stage transmission is adopted, the rection ratio will be greater Compact structure and small volume. Due to the planetary transmission principle, the input shaft and output shaft are on the same axis line, so that the size of the machine can be as small as possible Stable operation, low noise, large number of meshing teeth of cycloid pin teeth, large overlap coefficient and mechanism of mechanical balance limit vibration and noise to a minimum Because the main parts are made of high carbon chromium steel, high strength is obtained by quenching treatment (HRC58-62), and rolling friction is used in some transmission contacts, so they are rable and have long service life Reasonable design, convenient maintenance, easy disassembly and installation, minimum number of parts and simple lubrication,

6. There is a certain relationship between the number of planetary gears and the rection ratio of the planetary recer. The rection ratio is the number of stages of the planetary carrier. Generally, the rection ratio is below 40, and the recer is a two-stage structure. More than 40 is generally three-stage structure, more than 200 is generally four-stage structure, the number of planetary gears in each stage is 3, 4, 5 or more, which will be different according to the actual speed ratio and design.

7. There are many models and specifications of planetary gear recers. For example, large planetary gear recers and small planetary gear recers are used for different purposes
the output power of large planetary gear recer can reach 220kw, which is widely used in mining, metallurgy, wharf, lifting, transportation, construction, petroleum, energy, electric power and other large engineering fields; There are: Siemens, Jiepai, etc
