How to Improve Reducer’s Lifespan

- Nov 04, 2020-

Everyone knows that the service life of the reducer depends on the external load and internal wear rate. Excessive loads on the surface and inside of the reducer may cause tooth fracture, shaft fracture, and wear of moving parts, and the wear of moving parts may make it difficult to form a smooth oil film. Therefore, when the reducer is in the first shape and uses hardened gears, we can improve its service life is as follows:


First, it is necessary to avoid excessive external loads on the components driven by the reducer.


Secondly, the wear of the internal bearings or gears of the reducer should be limited within a reasonable range.


Third, we should try our best to ensure that the inside bearing and the gear meshing surface conform to the fluid dynamic smooth oil film.

1. Install the reducer correctly to avoid excessive force.

The reducer device must meet the corresponding device requirements, so as to avoid large additional force (that is, increased external force) due to poor alignment, insufficient matching accuracy, excessive vibration and other reasons, which will accelerate the damage of the reducer. reducer. Such failures should be discovered and dealt with in time at the early stage or during operation, otherwise it will vibrate the load and cause abnormal conditions, such as accelerated wear or bearing slip rings, thereby shortening the service life of the bearing.


2. Repair the driven parts and reducer in time to avoid excessive load on the reducer.

The components driven by the reducer will bear excessive external loads due to wear, chipping, cracking or damage of the bearings. Therefore, it is necessary to formulate and implement targeted random inspection and maintenance specifications to avoid excessive external loads for daily maintenance work, thereby reducing the service life of the reducer. For example, the reducer itself can be monitored through 5-sensing, vibration monitoring, lubricating oil ferrite analysis and other detection measurement (such as lubricating oil, vibration, temperature, noise, etc.) in order to detect existing problems or dangers in time. Check, correct or replace damaged parts in time to ensure that the operating condition of the reducer itself meets the requirements, and avoid excessive internal load.


3. Ensure that the bearing and tooth surface structure conforms to the fluid dynamic smooth oil film.
