' ( ) Reducer is generally used for transmission equipment with low speed and high torque. It transmits the power of electric motor, internal combustion engine or other high-speed operation through the number of teeth on the input shaft of the reducer. A small number of gears mesh with the large gear on the output shaft to achieve the purpose of deceleration. Ordinary reducers will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.

' () The main feature of the worm gear reducer is that it has a reverse self-locking function, which can have a larger reduction ratio, and the input shaft and output shaft are not on the same axis. , are not on the same plane either. However, they are generally larger in size, have low transmission efficiency and low precision. The harmonic transmission of the harmonic reducer uses the controllable elastic deformation of the flexible

components to transmit motion and power. It is small in size and has high precision, but the disadvantage is that the flexspline It has limited life, is not impact resistant, and has poor rigidity compared with metal parts. The input speed cannot be too high. The advantages of planetary reducer are relatively compact structure, small return clearance, high precision, long service life, and the rated output torque can be very large. But the price is slightly expensive. The gear reducer has the characteristics of small size and large transmission torque. Gear reducers are designed and manufactured on the basis of a modular combination system. There are many motor combinations, installation forms and structural solutions. The transmission ratios are finely graded to meet different operating conditions and achieve electromechanical integration. The gear reducer has high transmission efficiency, low energy consumption and superior performance. The cycloidal pinwheel reducer is a transmission model that adopts the principle of cycloidal pin tooth meshing planetary transmission. It is an ideal transmission device with many advantages, wide range of uses, and can operate in forward and reverse directions.
Function
Edit
' (), reduce the speed and increase the output torque at the same time. The torque output ratio is based on the motor output multiplied by the reduction ratio, but be careful not to exceed the rated torque of the reducer
, reduce speed At the same time, the inertia of the load is reduced, and the reduction of inertia is the square of the reduction ratio.

Usage

' ( ) Tips
' ( ), after running for ~3 hours, the first oil change should be performed, and the oil should be checked regularly in future use. If the oil is mixed with impurities or deteriorates, it must be replaced in time. Under normal circumstances, for reducers that have been working continuously for a long time, new oil should be replaced according to operating hours or once a year. For reducers that have been out of service for a long time, new oil should also be replaced before re-operation. The reducer should be filled with the same brand of oil as the original one and should not be mixed with oils of different brands. Oils of the same brand but with different viscosities are allowed to be mixed
. When changing the oil, wait until the reducer cools down and there is no danger of burning, but It should still be kept warm, because after complete cooling, the viscosity of the oil increases, making it difficult to drain. Note: Cut off the power supply of the transmission device to prevent unintentional power on. During work, when the oil temperature rises above ℃ or the oil pool temperature exceeds ℃, or abnormal noise is generated, stop using it and check the cause. After troubleshooting and lubricating oil replacement, operation can continue. Users should have reasonable usage and maintenance rules and regulations. The operating conditions of the reducer and problems found during inspection should be carefully recorded. The above regulations should be strictly implemented.
Maintenance
' () Selection of grease When selecting grease according to the bearing load of the traveling reducer, grease with small penetration should be selected for heavy loads. When working under high pressure, in addition to small penetration, it must also have high oil film strength and extreme pressure performance. When selecting grease according to environmental conditions, calcium-based grease is not easily soluble in water and is suitable for dry and less moisture-rich environments. When selecting grease according to operating temperature, the main indicators should be the dropping point, oxidation stability and low-temperature performance. The dropping point can generally be used to evaluate high-temperature performance. The actual operating temperature of the bearing should be lower than the dropping point -°C. The service temperature of synthetic grease should be lower than the dropping point °C.
It is forbidden to mix different lubricants with each other. The positions of the oil level plug, oil drain plug and breather are determined by the installation location.
Oil level inspection:
Cut off the power supply to prevent electric shock. Wait for the reducer to cool down
, remove the oil level plug and check whether the oil is full
Install the oil level plug.
Oil inspection:
Cut off the power supply to prevent electric shock. Wait for the reducer to cool
, open the oil drain plug, and take an oil sample
Check the viscosity index of the oil: if the oil is obviously turbid, it is recommended to replace it as soon as possible
For reducers with oil level plugs : Check the oil level and install the oil level plug if it is qualified.
Oil replacement:
After cooling, the viscosity of the oil increases and it becomes difficult to drain the oil. The reducer should change the oil at operating temperature.

Troubleshooting
' ( ) Due to the harsh operating environment of the reducer, wear, leakage and other faults often occur. The most important ones are:
, wear of the bearing chamber of the reducer, including Wear of the housing bearing box, the inner hole bearing chamber of the box, and the gearbox bearing chamber
Wear of the shaft diameter of the reducer gear shaft, the main wear parts are the shaft head, keyway, etc.
Wear of the bearing position of the reducer transmission shaft
, The joint surface of the reducer is leaking.
For the wear problem, the traditional solution is to repair welding or machining after brush plating, but both have certain disadvantages: the thermal stress caused by the high temperature of repair welding cannot be completely eliminated, which can easily cause material damage and cause parts to bend. Or it breaks and the brush plating is limited by the thickness of the coating and is easy to peel off. Moreover, the above two methods use metal to repair the metal and cannot change the matching relationship between hard and hard. Under the combined action of various forces, it will still cause re-wear. For some large bearing companies, it is impossible to solve the problem on site, and most of them rely on outsourced repairs. Contemporary Western countries mostly use polymer composite repair methods to solve the above problems, which have super strong adhesion, excellent compressive strength and other comprehensive properties. The use of polymer materials for repair can eliminate the need for disassembly and machining, and is not affected by the thermal stress of repair welding, and the repair thickness is not limited. At the same time, the product has a yielding property that metal materials do not have, and can absorb the impact and vibration of the equipment to avoid further wear and tear. It is possible to greatly extend the service life of equipment components, save a lot of downtime for enterprises, and create huge economic value.
As for the leakage problem, the traditional method requires disassembling and opening the reducer, then replacing the sealing gasket or applying sealant, which is not only time-consuming and labor-intensive, but also difficult to ensure the sealing effect, and leakage will occur again during operation. Polymer materials can control leakage on site. The material has excellent adhesion, oil resistance and a stretch of 3, which can overcome the impact of reducer vibration and effectively solve the problem of reducer leakage for enterprises
