How to choose planetary reducer type and brand? How to choose the planetary gear reducer? Reducer family, planetary reducer for its small size, high transmission efficiency, wide range of speed reduction, high precision and many other advantages, and is widely used in servo, stepper, DC and other transmission systems. Its role is to ensure accurate transmission under the premise, mainly used to reduce speed, increase torque and reduce the load / motor moment of inertia ratio. In choosing a planetary gear reducer, the deceleration ratio must be determined first. If our standard products do not have the speed reduction you need, please choose to approach or customize to our company.

Selection of speed ratio of planetary gear reducer:

In the choice of planetary gear reducer, we must first clear reduction ratio, determine the reduction ratio, please will you choose the servo motor rated torque multiplied by the reduction ratio is less than the sample products offer similar reducer rated output torque value obtained by the principle, but also consider the drive motor overload capacity and the actual required maximum torque. The maximum working torque required is less than 2 times the rated output torque.

Two. Selection of size and specification of planetary gear reducer:

After satisfying the above conditions, please select the smallest size reducer, the small reducer cost is relatively low. If you don't have enough space, the motor reducer is connected in a straight line. You can also choose the corner reducer, which can turn the torque to 90 degrees.

Three, the choice of planetary gear reducer accuracy (return clearance) choice:

Next, consider the return clearance of the planetary gear reducer. The smaller the backlash is, the higher the accuracy and the higher the cost. The user needs to select a reducer that meets its precision requirements.

Four, the selection of planetary gear reducer to consider the problem of service life:

Lateral and radial forces and average life should be considered. The horizontal / radial force reducer is of high reliability in installation and operation, and it is not easy to go wrong. The actual life can be calculated by the software given by the manufacturer. Usually, the average life of the servo motor is much longer than that of the servo motor.

Five, buy planetary gear reducer other matters needing attention:

After the above specifications have been met, you can select the reducer in the installation dimension, the shaft diameter and the input flange according to your product sample. Finally, you have to consider the weight of the motor to be supplied. A reducer is only allowed to match the motor less than a certain weight. The motor is too heavy and will cause damage to the output flange of the gear reducer for a long time.

Planetary reducer is widely used in servo, stepping and DC transmission systems because of its small size, high transmission efficiency, wide deceleration range and high precision. In the premise of ensuring accurate transmission, it is mainly used to reduce speed, increase torque and reduce the load / motor moment of inertia ratio.

The key technical parameters of the reducer are reduction ratio, average life, rated output torque, return clearance, full load efficiency, noise, transverse / radial force and working temperature.

Reduction ratio: the ratio of output speed to input speed.

Series: planetary gear wheel and around a sun gear reducer independently, such as for a gear reducer, we called "a". In order to obtain a larger reduction ratio, multi-stage transmission is required, and the reduction ratio is from 3 to 512.

Average life: refers to the speed reducer at rated load, the maximum input speed of the continuous working hours.

Rated output torque: refers to the rated load, long-term work allows the output torque. The maximum output torque is two times that value.

The return gap: the output end is fixed, the input end of the clockwise and counter clockwise, the + 2% torque Rated torque output when the reducer input has a tiny angular displacement, the angular displacement is the return gap. The unit is "arc"".

Lubrication: planetary reducer needs no lubrication during use.

Full load efficiency: the transmission efficiency of the reducer under the maximum load condition. It is a key index to measure the speed reducer. The reducer with full load efficiency has little heating, and the whole performance is good.

Noise: the unit is decibel (dB) A. This value is measured at the input speed of 3000 revolutions per minute, without load, from a meter distance of the reducer.
