Common troubleshooting methods of reducer 

1. Improving the Quality of Mechanical Assembly            

Before the assembly of the reducer, the relevant personnel need to check the components and components assembled to see if they are uniform, conform to the specifications and are dedicated to the reducer. The replacement components needed in the maintenance process of reducer should be in accordance with the original parts in standard. When disassembling these parts, the relevant personnel should also be careful to avoid damaging the parts [4]. Parts such as gears and turbine worms are very important, so the relevant personnel must ensure that the types and standards of spare parts before and after replacement are identical. In addition, the two parts appear in pairs, and the relevant personnel need to be replaced to make all of them be replaced, so that the replacement parts can be matched and adapted. For the output shaft, the relevant personnel should pay attention to controlling assembly tolerance to make the installation position correct, and also to maintain the hollow shaft, so that it will not produce excessive wear and tear in application. The quality of assembly components and assembly quality must be guaranteed, so it is not easy to fail in application.            

2.  Optimum selection of lubricants and additives            

The failure of lubricating oil or the decline of oil level will directly lead to serious wear and tear of gears and related accessories, so the relevant personnel should strictly control the lubricating oil during the fault treatment. It mainly chooses its type and controls its adding amount. In the operation of reducer, the relevant personnel should judge the application status of lubricating oil by means of side knocking and side knocking. In the application of lubricating oil, relevant personnel should combine it with additives. Additives can form protective film, which can reduce the probability of oil leakage and protect the quality of lubricating oil.            

3.  Clear Installation Method            

Vertical installation will affect the effective contact area between lubricating oil and lubricating parts, resulting in loss of lubricating oil and other phenomena, but also lead to wear and tear of related parts, so the relevant personnel should eliminate this installation method [5]. Horizontal or other ways are optional. After taking good protective measures, relevant personnel can use this installation method to install.            

4. Measures to Reduce Faults  For the faults, leakage, vibration and noise of gear parts, the relevant personnel should take special measures to deal with them. Aiming at parts failure, it mainly refers to wear and tear. Relevant personnel can make use of repair welding and brush plating to make the worn parts refreshed. If the surface of the parts is still incomplete, the relevant personnel should replace them. In order to avoid replacement and increase the service life of components, the relevant personnel should choose the processing and repair methods. The components made of polymer materials can be processed and repaired without disassembly. When the relevant personnel assemble the reducer at the beginning, they should choose this material. In view of the leakage failure, the relevant personnel should replace the sealing gasket or apply sealant, so that the seal can be restored as before, and then replace the lubricating oil to ensure the quality of the lubricating oil. For vibration and noise faults, there are also relevant solutions, and relevant personnel should implement them one by one.           

5. Concluding remarks           

There are many types of reducer, and the faults produced by each type are similar to each other. Only by comprehensively grasping the fault information, can the fault be accurately judged. Therefore, the relevant personnel should take all types of reducer as the research object. In the process of fault treatment, the way of handling is very important. Fault analysis and diagnosis are also very important. The former belongs to the result, and the latter belongs to the process. In the process of treatment, only by finding out the cause and location of the fault, can the method of fault treatment be achieved. And after the treatment of the fault, the frequency of the recurrence of the fault will be reduced. Relevant personnel must properly handle the failure and make relevant records.
