Nowadays customer have a wide variety of High Precision Gearboxes to choose from which are capable of fulfilling diverse applications. There are several aspects customer has to think of before buying a Gearbox like Service, load, size, type, Input speed, Output RPM, frame size etc or it will result to an buying of expensive Gearbox. Considering all the above factors will ensure cost effective solution that is suitable for application. The more data or information the customer provides us it is more easy for us to suggest a appropriate solution for any application. For More Information - https://smdgearbox.com/Blogs

1. Planetary Gearbox Selection
( SMD GEARBOX )

2. How to choose a suitable planetary
reducer?
Planetary Reducer is a product that amplifies torque
and reduces speed. When used in conjunction with
a motor, it can provide a high-precision and powerful
control module. Therefore, it is necessary to select
suitable products according to the torque and
accuracy level.

3. The Frame number is determined according to the
torque.
The power source will have the effect of torque amplification after
the reduction ratio. The output torque value of the reducer is
proportional to the reduction ratio. When the ratio is larger, the
torque value will be higher; but the gear set of the reducer has its
limit, Therefore, the "rated output torque" indicated in the technical
data of the product means that the product operates under this data
and the product can work stably, so the frame number must be
selected from the torque requirement.

4. Model according to accuracy.
Positioning will be required in the automation process. When the positioning accuracy
requirements are higher, higher-end products need to be selected, and vice versa. Accuracy of
planetary reducer Planetary reducers are often used in the field of precision motion control to
meet the application requirements of high torque, high torsional rigidity and low backlash.
Selecting the appropriate reduction ratio can provide greater torque, so as to run at the best
speed to achieve the best effect, reducing the moment of inertia of the load can increase the
stability of the equipment, and by using the planetary reducer, the machine manufacturer can
choose more Small and more economical motion control modules make the application range
of planetary reducers cover the entire automation field. The products can be seen in the
following industries: Planetary reducer is a product that amplifies torque and reduces speed.
When used in conjunction with a motor, it can provide a high-precision and powerful control
module. Therefore, it is necessary to select suitable products according to the torque and
accuracy level. 11 It is called "backlash", which refers to the backlash of the gear set, which
is defined as the angle value at which the output shaft of the reducer can rotate when the input
end is fixed.

5. Model according to accuracy.
According to customer needs, there are standard series of output shaft and connecting
surface for customers to choose, and can also be developed according to customer's
special needs. Many of Planetary gearbox are combined with Right Angle Gearbox and
Hollow Rotary Gearbox to achieve higher reduction ratios for a specific applications.

6. Below is a Motor watt and corresponding frame sizes, also before finalizing frame size also check
torque is within the nominal mentioned torque in specification chart/catalog
To calculate output torque
Output Torque = Input Motor Rated Torque X Ratio

 SS120 -750W- and for low ratio 2kw
 SS150 - 1kw- and for low ratio 3 kw
 SS180 - 2kw and for low ratio 5 kw

7. The life of the reducer selected.
According to the shaft radial force is affected by the internal bearing. The bearing life
can be estimated by the load and speed. When the radial load of the reducer is high, the
bearing life will be shortened. At this time, it is recommended to use Great product.
SMD Gearbox are made in Taiwan and utmost care is taken to maintain the Quality of
the gearbox with all the major testing done while the production of Gearbox :-
1) Backlash testing.
2) Torque Testing.
3) Maximum Torque Testing.
4) Load and No Load Testing.
5) Efficiency Testing.
6) Sound and Vibration Testing.
