[Abstract] Reducers are widely used in daily life, and are used in various mechanical systems in industrial production, such while: autos, ships, some large equipment and some factory creation lines. The range of the reducer is normally very wide, from the transmission of the bigger power to the transmitting of the specific angle, the reducer can work very well. The inner framework of the reducer is usually a range of gears of different specs. By interlocking the things, the velocity input from the insight shaft can become decreased, and the velocity can be reduced to the mechanised device through the output shaft, and the speed can become noticed. . This paper primarily research the common faults of the reducer and lists several effective solutions.

The main function of the reducer is to convert the power and provide the right power for the mechanical operation. When the reducer functions, it primarily relies on the equipment conversion rate of different sizes, and finally the electric motor shaft quickness reaches the needed range, and a big torque mechanism can be obtained. In the current useful software, the reducer is used to transmit mechanical velocity and convert mechanical power, and the program of the reducer is usually even more and more prevalent. In the creation process of general commercial enterprises, the speed transformation and deceleration of the reducer are generally used to understand the acceleration conversion of several mechanised products. Consequently, once the failing of the reducer will significantly influence the creation activities of the enterprise, it is extremely essential to make accurate decision for the failing of the reducer and also to find a remedy to guarantee the normal operation of numerous gadgets.

1 Reducer common failure
1.1 Parts high temperature leaking
In order to enhance the functioning efficiency of the reducer, most reducer manufacturers choose non-ferrous materials to manufacture the turbine of the reducer, and the materials for production the worm is the harder steel. This causes the reducer to constantly stroke and glide between the parts during the working procedure, which produces a great deal of warmth, and because the components of the internal parts of the reducer are different, the degree of thermal extension of the material is certainly different, so that the first fitting distance between the parts It turns into smaller sized and continuously wears out friction. At the same period, the lubricating oil between the parts is normally also affected by the temperature rise, and the concentration becomes thin, causing in essential oil leakage racks failure of the reducer.

1.2 Turbine wear failure
The materials used to make the worm equipment are generally nonferrous metals, such as tin bronze alloy, and the worm is made of 45 steel, and in order to ensure the hardness, it will be quenched and its hardness can reach HRC45-55. When the reducer is usually in regular operation, the worm offers a high hardness, which causes long lasting friction with the turbine during operation, ending in critical use of the turbine. Since the turbine and the worm are essential elements of the reducer, the put on of the turbine can lead to a reduced support lifestyle of the reducer. In addition to the turbine and worm hardness mismatch, the turbine use and tear, the reducer program and model, the reducer functioning period and the load during the procedure of the reducer will create different degrees of use on the turbine of the reducer.

1.3 Drive little helical gear wear
This type of failure generally occurs in vertical reducer equipment, which is due to certain problems in the type and amount of lubricant. When setting up the vertical reducer, the staff will add a specific quantity of lubricant to the inside. When the reducer is certainly controlled for a period of time, due to the usage of lubricating oil or leakage, the lubrication of the parts of the reducer can be lacking. When the acceleration reducer halts working, the lubricating essential oil will steadily drop to the bottom level of the reducer due to gravity. When the speed reducer begins again, the top component of the gear or additional parts does not have the protection of lubricating oil, which is definitely even more serious. Use and tear. In this method, not only will the lifestyle of the reducer end up being decreased, but also other problems will occur due to friction between the parts.

1.4 Worm bearing damage
In the course of action of failure of the reducer, also if the covered package is well shielded, the gear oil may be emulsified, causing in damage, corrosion and rust of the bearing. This is because the moisture produced by the sudden air conditioning of the gear oil during the operation of the reducer is definitely agglomerated.

2 Effective way to solve the problem of reducer
2.1 Improve the functioning environment
The working environment will have a very large impact on the operating efficiency of the reducer. Dust and great contaminants in the working environment of the reducer will enter the inside of the machine through the distance of the reducer casing. Since there are many viscous substances such as lubricating essential oil inside the reducer, these little contaminants will adhere to the lubricating oil after entering. When the machine is usually working, it will become transmitted to all parts of the reducer as the equipment rotates, which will lead to an boost in the friction of the reducer parts, and ultimately the equipment device will malfunction. Therefore, in purchase to assure the regular operation of the reducer, the staff should pay out interest to the operating environment of the reducer. Specifically in some dusty working conditions, a defensive cover can be added to the reducer casing relating to real needs to decrease the debris entering the machine and prevent dust from getting into the machine, which affects the stable operation of the machine. . In addition, if the operating environment of the reducer can be relatively severe, after the daily work is finished, it is definitely necessary to clean and check the reducer in period, primarily to clean the dust attached to the body of the decrease equipment to avoid the dirt and impact the reducer. Normal procedure ensures stable procedure of the reducer.

2.2 Improve the machining precision of the reducer
The common faults of the reducer also include the oil leakage of the chassis. The fundamental problem is definitely mainly caused by the issue of machining precision in the developing procedure of the reducer. As a result, when the reducer fails, the maintenance employees can trim the machining precision and enhance the machining accuracy of the reducer. First of all, in purchase to prevent oil leakage in the framework, the joint between the higher and lower casings of the machine should become floor to make sure that the casing of the casing can end up being tightly involved; second, in the process of installing the upper and lower casings of the reducer, a joint should become placed at the joint of the casing. The closing remove is normally then coated with a coating of sealant on the joint to form a closed continuous apron, which successfully eliminates the essential oil leakage on the container surface area and ensures the reliability of the operation of the reducer.

2.3 Improve the installation quality of the reducer
The unreasonable installation phase of the reducer is one of the biggest causes of the current failure of the reducer. As a result, the business should pay interest to the set up process of the reducer to make certain the dependability of the reducer. Initial of all, in the process of installation of the reducer, advanced calculating instruments should be completely used to reinforce the detailed inspection of the parts and the measurements of the parts of the reducer and the accuracy of the joint parts. For example, check the bones of the higher and lower cabinets. The verticality and level between the shaft, the shaft and the bearing and the patience between the gears; secondly, the set up and inspection strength of the reducer should end up being increased, and the performance should be checked before beginning up. For example, the bolts at the connection component of the reducer appear loose, and should be reinforced in period. At the same period, the vibration degree of the reducer is usually decreased by effective inspection, and the operation effect of the reducer can be improved to some degree. These duties can successfully warranty the quality of the reducer set up and place a solid basis for the simple procedure of the reducer.

2.4 Specification of installation and fix practices
In order to assure the installation or repair quality of the reducer, the company needs to purchase the parts in person, and in the process of disassembling and installing the worm, the worm wheel and the bearing, try to avoid utilizing a hammer and various other tools to directly strike, so as not to affect the cooperation between these parts. patience. When replacing parts, pay out attention to the accessories that match the mechanised model. In the procedure of assembling the result bearing, it is certainly necessary to pay interest to the shared complementing of the patience values. When M≤50mmeters, H7/e6 is used; when Chemical>50mm, L7/meters6 is certainly adopted. At the same time, it can be necessary to use reddish colored Dan oil and anti-adhesive agent to attain the purpose of safeguarding the hollow shaft, and to avoid the put on and corrosion of the parts to a certain level, which is usually beneficial for disassembly and installation during maintenance.

In summary, many businesses want to make use of reducers in the production process. However, due to numerous elements, the reducer frequently provides different faults during procedure, which seriously affects the safety and reliability of the reducer. It also impacts the production performance and product quality of the organization. At this time, it is definitely necessary for the management and maintenance staff to perform on-site inspections on a regular basis, and also to find out the cause of the failing of the reducer, and instantly provide matching maintenance and maintenance to prevent affecting the regular production procedure.
