Introduction
The main function of the reducer is to convert the power and provide the right power for the mechanical operation. When the reducer works, it primarily relies on the gear transformation speed of different sizes, and finally the motor shaft quickness reaches the needed range, and a huge torque system is definitely acquired. In the current useful program, the reducer can be used to transmit mechanical quickness and convert mechanical power, and the software of the reducer can be more and even more extensive. In the production procedure of general commercial enterprises, the velocity conversion and deceleration of the reducer are generally used to recognize the acceleration conversion of different mechanical devices. As a result, once the failure of the reducer will significantly have an effect on the production actions of the enterprise, it is normally very important to make accurate decision for the failure of the reducer and also to find a answer to guarantee the regular operation of different devices.
1 Reducer common failure
1.1 Parts 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 continuously rub and slide between the parts during the working process, which produces a great deal of high temperature, and because the components of the inner parts of the reducer are different, the level of thermal growth of the material is definitely different, so that the first appropriate difference between the parts It turns into smaller and continuously wears out friction. At the same period, the lubricating oil between the parts is usually also affected by the temp rise, and the concentration becomes thin, ending in essential oil leakage failure of the reducer.
1.2 Turbine wear failure
The components used to produce the worm gear 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 certainly in normal procedure, the worm has a high hardness, which causes long-term friction with the turbine during operation, ensuing in severe use of the turbine. Since the turbine and the worm are key parts of the reducer, the use of the turbine can lead to a reduced support existence of the reducer. In addition to the turbine and worm hardness mismatch, the turbine put on and rip, the reducer program and model, the reducer working time and the fill during the procedure of the reducer will create different levels of use on the turbine of the reducer.
1.3 Drive small helical equipment wear
This type of failure primarily occurs in vertical reducer equipment, which is due to certain problems in the type and amount of lubricant. When installing the straight reducer, the staff will add a particular amount of lubricant to the inside. When the reducer is usually managed for a period of period, due to the consumption of lubricating essential oil or leakage, the lubrication of the parts of the reducer is definitely lacking. When the velocity reducer halts working, the lubricating essential oil will steadily drop to the bottom of the reducer due to gravity. When the swiftness reducer starts again, the top component of the gear or additional parts lacks the protection of lubricating essential oil, which is normally more significant. Wear and rip. In this way, not just will the existence of the reducer become reduced, but also additional complications will occur credited to friction between the parts.
1.4 Worm bearing damage
In the practice of failure of the reducer, even if the covered box is well shielded, the gear oil might be emulsified, ending in damage, corrosion and corrosion of the bearing. This is since the moisture produced by the sudden air conditioning of the equipment oil during the operation of the reducer is usually agglomerated.
2 Effective speed reducer method to resolve the issue of reducer
2.1 Improve the functioning environment
The working environment will have a extremely large impact on the operating efficiency of the reducer. Dust and good particles in the working environment of the reducer will enter the inside of the machine through the distance of the reducer housing. Since there are many viscous chemicals such as lubricating essential oil in the reducer, these little particles will adhere to the lubricating essential oil after entering. When the machine is normally functioning, it will become sent to all parts of the reducer as the equipment rotates, which will result in an boost in the friction of the reducer parts, and eventually the equipment device will breakdown. Therefore, in purchase to ensure the normal procedure of the reducer, the staff should pay out attention to the operating environment of the reducer. Specifically in some dusty functioning conditions, a protecting cover can end up being added to the reducer casing regarding to actual requirements to reduce the debris entering the machine and prevent dust from getting into the machine, which impacts the stable operation of the machine. . In addition, if the operating environment of the reducer can be fairly harsh, after the daily work is certainly completed, it can be necessary to clean and check the reducer in time, generally to clean the dust attached to the body of the reduction equipment to avoid the dirt and influence the reducer. Regular operation ensures steady 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 issue is generally caused by the issue of engineering accuracy in the processing procedure of the reducer. Therefore, when the reducer falters, the maintenance workers can trim the machining accuracy and enhance the machining accuracy of the reducer. Initial of all, in purchase to prevent oil leakage in the framework, the joint between the top and lower casings of the machine should be surface to ensure that the casing of the casing can end up being tightly involved; second of all, in the procedure of installing the higher and lower casings of the reducer, a joint should be inserted at the joint of the casing. The closing strip can be then coated with a coating of sealant on the joint to type a closed constant apron, which effectively 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. Consequently, the business should pay out attention to the installation process of the reducer to make sure the reliability of the reducer. Initial of all, in the procedure of installation of the reducer, advanced calculating equipment should end up being fully used to improve the detailed inspection of the parts and the measurements of the parts of the reducer and the precision of the joint parts. For example, check the joint parts of the top and lower cabinets. The verticality and level between the shaft, the shaft and the bearing and the tolerance between the gears; secondly, the set up and inspection strength of the reducer should be improved, and the overall performance should be checked before beginning up. For example, the bolts at the connection component of the reducer appear loose, and should become strengthened in time. At the same period, the vibration degree of the reducer is certainly reduced by effective inspection, and the procedure effect of the reducer is definitely improved to some extent. These jobs can effectively promise the quality of the reducer installation and place a solid base for the soft procedure of the reducer.
2.4 Specification of installation and repair practices
In order to assure the installation or repair quality of the reducer, the company needs to buy 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 other tools to directly strike, so as not to affect the cooperation between these parts. tolerance. When changing parts, pay out attention to the add-ons that match the mechanised model. In the process of putting together the output bearing, it is definitely necessary to pay attention to the mutual matching of the threshold beliefs. When Deb≤50mm, L7/e6 is definitely adopted; when N>50mm, L7/meters6 is definitely adopted. At the same period, it is definitely necessary to make use of crimson Dan oil and anti-adhesive agent to accomplish the purpose of protecting the hollow shaft, and to prevent the use and rust of the parts to a particular extent, which can be advantageous for disassembly and installation during maintenance.
Conclusion
In overview, many companies need to use reducers in the creation procedure. However, credited to several factors, the reducer frequently has different errors during procedure, which significantly affects the protection and reliability of the reducer. It also impacts the production performance and item quality of the company. At this time, it is usually required for the administration and maintenance employees to perform on-site inspections on a regular basis, and also to discover out the cause of the failure of the reducer, and immediately provide related maintenance and maintenance to avoid influencing the regular creation procedure.
