The planetary reducer is a kind of transmission mechanism, which needs to transmit torque to the working machine through the shaft and bearing, so the relationship between transmission efficiency and quality is directly related to the bearing, and the sliding quality and life of the bearing will affect the planetary reducer. overall quality and performance.The bearing has the following functions in the planetary reducer: ① prevent the loss of lubricating oil when the gear is used inside the bearing, and ensure that the bearing is in a lubricated state; ② prevent the dust or harmful gas outside the bearing from entering the inner cavity of the bearing, and prevent the bearing from being damaged; ③ can support the rotation between gear shafts or connecting rods.The following focuses on the analysis of the impact of bearing water on the planetary reducer bearings.1. Corrosion and oil emulsification: Water directly erodes the bearing surface to form iron oxide.Water together with acid in the oil (generated by the presence of water) raises the corrosion potential and increases galvanic corrosion of bearings.Rust and corrosion cause rapid surface deterioration when abrasive particles appear on metal surfaces.Metal rust surface after wear and tear Read More

As an indispensable precision transmission equipment in industrial production, the servo planetary reducer has certain requirements on the environment, and temperature is the key.Many friends will encounter the situation that the machine cannot be turned on in a low temperature environment during use.In this case, you only need to move the equipment to a room with high temperature or heat up the reducer on the spot, and when the equipment itself can generate heat when it is running, it can work normally.The reason why the servo planetary reducer will be stuck at low temperature is divided into several aspects: first, the gear oil we use has a low freezing point, and it will harden when the ambient temperature is low, making the reducer unable to operate.Secondly, the internal components of the reducer are affected by thermal expansion and contraction in low temperature environments. The metal materials of different components are different, and the degree of cold shrinkage is also different. The fastening parts and contact surfaces of the parts can produce greater friction, making the servo planetary reducer easier Stuck.Finally, the metal casing of the reducer may also Read More

Causes of gear pitting of planetary reducer 1. The influence of reducer manufacturing and assembly accuracy One of the reasons for early pitting of planetary reducer is due to low assembly accuracy, resulting in reduction of gear contact area and local overload, so that the actual contact stress exceeds The allowable contact stress of the gear material, which is caused by the fact that the two centerlines of the gear pair are not parallel or the cross deviation is too large and the tooth direction error is too large during gear processing.The improper selection of gear material and heat treatment hardness results in low tooth surface hardness, which cannot meet the processing requirements, and is also an important cause of pitting corrosion.2. The influence of installation accuracy. Since the shaft alignment of the planetary reducer and the motor after installation does not meet the specification requirements, the motor coupling and the reducer input end coupling are not concentric, resulting in uneven force on the input end gear of the reducer. The side transmission gear is overloaded and stressed, causing pitting on the tooth surface, resulting in damage to the gear of the reducer and failure.3. The influence of lubricating oil Lubricating oil can reduce the Read More

Selection method of lubricating oil viscosity for planetary reducer 1. The viscosity of lubricating oil for planetary reducer is mainly realized by base oil and viscosity index improver. Among them, the viscosity of base oil is mainly related to molecular structure and molecular weight. The greater the average molecular weight, The greater the viscosity of the oil.2. A good viscosity index agent should have strong viscosity increasing ability, good shear stability, good low temperature performance and thermal oxidation stability.3. For lubricating oils of brands with viscosity at the same time, if unrefined base oil and viscosity index agent are used, although a certain viscosity standard can be achieved after deployment, the performance of viscosity-temperature and shear stability is poor, and the same can be achieved. Less than the specified life cycle.In actual production, the lubricating oil viscosity of the planetary reducer can be selected according to the above method. For low-speed and heavy-duty reducers, better lubricating oil should be selected, and unrefined base oil or poor viscosity index agent should be selected as far as possible, because the base Both the oil and the viscosity index agent are better, the greater the viscosity of the gear oil, the better the Read More

The correct installation, use and maintenance of the servo planetary reducer is an important part of ensuring the normal operation of mechanical equipment.Therefore, when installing the servo planetary reducer, it must be assembled and used in strict accordance with the following installation and use related matters.How to ensure the normal operation of the servo planetary reducer?Bappman Industrial Technology (Guangdong) Co., Ltd. has the following suggestions: 1. Before installation, confirm whether the motor and the servo planetary reducer are intact, and strictly check whether the size of the connecting part of the motor and the reducer matches. This refers to the size of the motor. Dimensions and matching tolerances of positioning bosses, input shafts and reducer grooves.2. When installing the servo planetary reducer, the central axis of the transmission mechanism should be centered, and the error should not be greater than the compensation amount of the coupling.Good alignment increases lifetime and achieves desired transfer efficiency.3. When installing the transmission component on the output shaft, it is not allowed to hit with a hammer.Typically, the assembly clamp and the inside of the shaft end Read More

The planetary reducer power selection standard stipulated by our country has two parameters: one is the mechanical power, that is, the power determined under the strength conditions of the main components of the reducer (gears, shafts, etc.); It is the maximum power determined when the load at normal temperature and deceleration belt runs continuously to the allowable temperature of the thermal equilibrium state, which is an important indicator of the planetary reducer Selection.The thermal power is the maximum power that the planetary reducer can continuously transmit within the specified lubricating oil equilibrium temperature range.The equilibrium temperature is the lubricating oil temperature at which the heat generated and dissipated by the lubricating oil in continuous operation is basically balanced, and the temperature rise basically stops.The thermal power depends on the efficiency of gear pairs, bearings, etc., working conditions, the maximum allowable oil tank temperature (lubricating oil temperature) and the cooling measures taken.The use of more than the thermal power means that the oil film is thinned or broken, which reduces its ability to resist pitting and gluing, and shortens the working life.As the planet decreases Read More
