Can Any one say about the methods used for checking the backlash in a
industrial gearbox (Reducer)
industrial gearbox (Reducer)
It can be Helical, planetary, Bevel-Helical, Etc....
As a gearbox how can we calculate the Backlash of the gerabox
any useful links, etc....
Thanks and Best Wishes

How to select the planetary reducer?
In the family of gear reducer, due to its small size, high efficiency, wide range of reduction, high accuracy and many other advantages, planetary reducer is widely used in servo, stepper, DC and other transmission system. Under the premise of ensuring the precision transmission, planetary reducer mainly used to reduce the speed, increase the torque and reduce the inertia ratio.
To select a planetary reducer, you first have to determine the reduction ratio. If there is no standard sample with a reduction ratio you need in our company, please make your order to our company.
After determined the reduction ratio, please multiply the rated torque of the servo motor with the reduction ratio, in der regal, the rated output torque should be less than the values obtained on the speed reducer that provided in the product catalog, at the same time, the overload capacity of the motor and the actual required maximum operating torque should also be considered. The required maximum operating torque is 2 times less than the rated output torque. After having been met the above conditions, please choose the smallest reducer, on account of small reducer is relatively low number of evaluations.
Next to consider the return gap of planetary reducer. The smaller the return gap, the higher the accuracy as well as the cost. Users could choose serial reducer that meet their accuracy requirements. We should also take account of the lateral / radial force and average life span. Its average life expectancy is far more than the service life of the servo motor. After having been met the above index, according to the product catalog provided by our company, users can select the reducer with your motor phase adaptation in installation size, shaft diameter and input flange.
Finally, you must consider the weight of the motor. A speed reducer is only allowed to be equipped with motors in a certain weight. If the motor is too heavy, the long time running will damage the input flange of the reducer.

The micro motor reducer serial products is mechatronic product composed of micro gear reduction box, governor, speed control motor or constant speed motor. Here to provide a general reduction motor troubleshooting method:
1, The motor overheating, check the actual load, adjust to the specified value or replace the larger power of the reducer, Oil using in accordance with the provisions.
2, knocking noise and irregular mesh micro reducer oil checking. Micro reducer lubrication oil may deteriorate after a period of time using because of various reasons, therefore, to check the oil lubrication at regular intervals is necessary. Micro deceleration motor to check the oil quality is first cut off the power supply and wait for the micro reducer cooling, open oil drain bolt to obtain oil, if oil deterioration, the lubricating oil should be immediately replaced.
3, Abnormal stable operation noise. Bearing damage, need to replace the bearing.
4, Abnormal operation noise. Renewing the oil or more oil to rated value.
5, Air leakage. Correct oil level and correct installation of ventilators
