Reducers Knowledge

Planetary reducer is a commonly used industrial transmission equipment, and it has a wide range of uses. Let’s first look at the characteristics of planetary reducer: planetary gearboxes have light weight, small size, large transmission ratio range, high efficiency, stable operation, low noise, strong adaptability, high precision, low clearance, and long service life.  The rated output torque can be made very large and so on. The internal gear of the planetary reducer adopts 20CrMnTi carburizing, hardening and grinding teeth. It has the characteristics of small size, light weight, high load capacity, long service life, stable operation, low noise, large output torque, large speed ratio, high efficiency and safe performance. It has the characteristics of power splitting and multi-tooth meshing. It is a new type reducer with wide versatility. The maximum input power can reach 104kW. Suitable for industrial sectors such as lifting and transportation, construction machinery, metallurgy...

How can you judge the quality of the planetary reducer you buy? Pay attention to these three aspects to know. 1. Look at the quality of the double arm The double swing arm refers to the support on both sides of the gear of the planet carrier. When the output shaft is driven with load, the gear will not deviate in the opposite direction, and there is a high-speed bearing at the connection between the planet carrier and the input shaft to make the gear transmission more stable. 2. Look at the quality of the input shaft The input shaft is divided into an integral input shaft and a split input shaft. The one-piece structure eliminates the error of the connection between the input shaft and the sun gear, making it more accurate, more concentric, with greater torque, and more stable transmission. 3. Look at the quality of the ring gear If a split structure is adopted, most of the inner gear ring adopts pull teeth, and then the gear ring is inserted into the box body. Some manufacturers use s...

Planetary reducer is one of the reducers currently used. According to the power, it is divided into high-power planetary reducer and small-power planetary reducer. Different types of planetary reducers are used in different industries. When selecting planetary reducer models, parameters, and What are the main points to consider when specifying? What to pay attention to? Power This directly reflects the power efficiency of the motor, and the calculation formula for the power size of the motor selection: Reducer torque = 9550 × motor power × speed ratio × use factor / motor input revolutions The calculation formula is T=9549 * P / n. P is the rated (output) power of the motor in kilowatts (KW) The denominator is the rated speed n and the unit is revolutions per minute (r/min) P and n can be found directly from the motor nameplate. Therefore, the reducer power P=T*n/9550. Rotating speed This parameter refers to the rated speed of the motor, which is directly related to the speed ratio whe...

The planetary gear reducer is a precision reduction motor, which has great working efficiency and applicability; according to the power, the planetary gear reducer is divided into a small planetary gear reducer and a high-power planetary reducer, which are used in different fields and scenarios; the following details are introduced The structure and working principle of planetary gear reducer. The structure of planetary gear reducer The structure of planetary gear reducer is mainly composed of planetary gear, sun gear, ring gear, planet carrier, and transmission source (motor). Working principle of planetary gear reducer 1. Number of stages: the number of sets of planetary gears. Because one set of planetary gears cannot meet the larger transmission ratio, sometimes 2 or 3 sets are needed to meet the user’s requirements for larger transmission ratios. Due to the increase in the number of planetary gears, the length of the 2-stage or 3-stage reducer will change. Increased, efficiency wi...

The planetary reducer consists of the main body, output shaft, output shaft oil seal, output bearing, sun nut, planet carrier, internal gear ring, planet gear, stage gear, needle shaft, sun gear, C-shaped buckle ring, input bearing, input shaft It is composed of oil seal, inlet flange, O-ring, vent plug, key, gasket, hexagon socket screw, etc. 1. Transmission principle The transmission structure of the planetary reducer is currently the most efficient combination of gear reducers, and its basic transmission structure consists of four parts: ① Sun gear. ② Planetary gear (combined with planet carrier). ③ Internal gear ring. ④ Stage gear. The driving source activates the sun gear in a direct connection, and the sun gear drives the planetary gears assembled on the planetary gear carrier to run. The entire planetary gear system automatically runs and rotates along the outer gear ring, and the planet carrier is connected to the output shaft for output to achieve acceleration. A higher reduct...
