What kind of planetary reducer is equipped in the field of robotics?

Planetary reducer for robots: Pursue compact structure, high power output, high frequency operation, high strength torsion resistance and rigidity, and high maximum speed accuracy.

The advantages of Bupermann planetary gear units in the field of robotics enable them to provide standard products according to specific requirements, individually configurable and reliable and precise solutions.

Requirements for planetary reducers in the field of robotics.

The highly dynamic, linear operation of industrial robots requires planetary gear units to be robust enough and operate efficiently.

Due to the high dynamics of robots, especially multi-axis robots, the drive components are required to have a very low dead weight in order to achieve good control and thus more efficient cycle times.

Applications such as pick-and-place robots require high speeds, repeatability, and stability of precise positioning under heavy loads to achieve fast and precise placement of the final product.

Highly automated robots need to operate 24 hours a day or even all year round, so the requirements for precision and stability are particularly high.

High-precision robots require that they must not deviate from the predefined path, even if the slight vibration or tracking deviation leads to the deviation of the running trajectory and leads to the increase in the variance of the production products, it will also produce a lot of production products in the scrap rate.

First of all, the general reducer has helical gear reducer (including parallel shaft helical gear reducer, worm gear reducer, bevel gear reducer, etc.), planetary gear reducer, cycloidal pin wheel reducer, worm gear reducer, planetary friction mechanical continuously variable speed change, etc. We take the worm gear reducer as an example, its main feature is that it has a reverse self-locking function, which can have a large reduction ratio, and the input shaft and output shaft are not on the same axis or on the same plane. However, the general volume is large, the transmission efficiency is not high, the structure of the planetary reducer is relatively compact, the return clearance is small, the volume is small, the installation is convenient and the bearing capacity is high, and the use will be more extensive, and it is generally used in servo, stepper, DC and other transmission systems.

Secondly, from the general reducer and planetary reducer technology, the planetary reducer is finely worked, the precision is high, and the box body of the planetary reducer is made of ductile iron, which greatly improves the rigidity and seismic resistance of the box. At present, its output torque can reach up to 2600000nm, the gears are carburized and quenched to obtain a high hard wear-resistant surface, and the gears are all ground after heat treatment, so the service life is longer than that of the general reducer and the noise generated in operation will be relatively small.

Finally, on the basis of the workmanship, the cost performance of the planetary reducer is more economical, but this mainly depends on the needs of the application and the requirements for the accuracy of the reducer and the size of the torque.

Planetary reducer.

The main structure is the planetary gear, which uses the planetary gear to achieve the effect of power distribution and multi-tooth meshing.

It has the characteristics of high rigidity, high precision (single-stage can be achieved within 1 minute), high transmission efficiency (single-stage is 97%-98%), high torque, small size, and lifelong maintenance-free.

Most of them are installed on stepper motors and servo motors to reduce speed, increase torque, and match inertia.

Ordinary reducer.

Compared with the planetary reducer, the accuracy and transmission efficiency are lower.

**It is also much lower than the planetary reducer.

The main feature of the ordinary reducer is that it has a reverse self-locking function, which can have a large reduction ratio, and the input shaft and the output shaft are not on the same axis or on the same plane. However, the general volume is large, the transmission efficiency is not high, and the accuracy is not high.

The advantages of Bapman planetary reducer are that the structure is relatively compact, the return clearance is small, the precision is high, the service life is very long, and the rated output torque can be very large. But slightly more expensive.

The development of planetary reducer in recent years makes the planetary reducer fine workmanship, high precision, the box of the planetary reducer is made of ductile iron, which greatly improves the rigidity and seismic resistance of the box, and has more advantages such as low noise, low backlash and high precision than ordinary reducer. The cost performance of the planetary reducer is a little higher, which is because of the reducer's requirements for accuracy and torque. The advantage of Shanghai Wanchao planetary reducer lies in high precision and low noise.

Friends of electromechanical professionals know that the reducer is a very precise mechanical equipment, and the planetary reducer is also one of the many reducers, and the planetary reducer has the following four differences from ordinary reducers.

1. Generally, the planetary reducer is larger in size, the transmission efficiency is not high, the structure of the planetary reducer is relatively compact, the return clearance is small, the volume is small, the installation is convenient and the bearing capacity is high, and the use will be more extensive, and it is generally used in servo, stepper, DC and other transmission systems.

2. In terms of the process of general reducer and planetary reducer, the planetary reducer has fine workmanship and high precision, and the box body of the planetary reducer is made of ductile iron, which greatly improves the rigidity and seismic resistance of the box.

3. The planetary reducer has a longer service life than the general reducer, and the noise generated during operation will be relatively small. Because the output torque of the planetary reducer can reach up to 2600000nm, the gears are carburized and quenched to obtain a high hard and wear-resistant surface, and all the gears are ground after heat treatment.

The gear of the planetary reducer is one of the very important components in the reducer, which plays an important role in the gear of the precision planetary reducer, and the good gear used in the planetary reducer has the following advantages: high power and stable gear ratio, please see the following content of Bapman for specific analysis.

1.High power.

Usually we use the mechanical equipment, gear transmission for high power, and closed transmission power of 96% 99%, for high-power transmission has a good economic development, helical gear structure is compact.

2.The gear ratio is stable.

The gears of planetary reducers are divided into two types, one is helical and the other is spur. The stability of the gear transmission ratio is the basic requirement for gears, and now the gear transmission on the market has been widely used, and because of this, the service life can be as long as ten or twenty years, and it is also because of this reason that many transmission equipment can not be compared.

"The main transmission structure of the planetary gear reducer is: planetary gear, sun gear, and internal ring gear. Due to the structure of the planetary reducer, the minimum single-stage deceleration is 3, and the maximum is generally not more than 10, and the common reduction ratio is:

3 4 5 6 8 10, the number of reducer stages is generally not more than 3, but some large reduction ratio custom reducers have 4 levels of deceleration. Compared with other reducers, planetary reducers have high rigidity and high precision (a single stage can be achieved within 1 minute).

Planetary reducer with output shaft: BPA type planetary reducer (BPA60, BPA90, BPA120, BPA140, BPA180, BPA220), BPB type, BPE type, BPD type.

Planetary reducer with output flange: BPF type.

Right-angle planetary reducer with output shaft: BPAR type, BPBR type, BPER type.

Buckman planetary reducer with output flange right angle: BPFR type.

Multi-output shaft spiral bevel gear servo reducer: BPT type, BPTA type, etc.

The selection of Bapman planetary gear reducer should consider its internal indicators such as the type of junction structure, installation size, bearing capacity, reduction ratio, output speed, axial force, radial carrying force, torsional rigidity, backlash, and importance, and should also fully consider the external structure such as installation form, working conditions, and working environment.

Choose according to your operating load, as well as the speed and accuracy you need to achieve on your side.
