- Inspection and precautions for oil quality of planetary reducerSince the special oil for the planetary reducer may deteriorate after the equipment has been in operation for a long time, which will seriously affect the use of the equipment, and more seriously, it may cause damage to the equipment and reduce the use efficiency. Therefore, we should treat the oil according to the requirements of the planetary reducer The oil quality of the equipment is checked regularly to ensure the normal use of the equipment.In fact, the use effect of the planetary reducer has a lot to do with its oil quality. You must not ignore the inspection of the oil quality during use.So, how should the oil of the planetary reducer be checked?The specific method of Bappman Industrial Technology is described in detail below: 1. The lubricating grease of the reducer will be mildewed due to various reasons within a period of time after use, so it is necessary to check the lubricating grease every quarter; 2. Check the oil , first turn off the switch power supply, wait for the reducer to turn on after water cooling, place a non-porous oil receiving plate under the oil filling foot of the reducer, then open the oil level oil foot bolt, add some oil
- How to reduce the safety hazard of planetary reducer?Probably everyone knows that no product can be 100% good, and the planetary reducer is the same. Since it cannot be perfect, it is necessary to prevent hidden dangers. The installation of the planetary reducer requires professional operation, and the accessories and materials used Guaranteed ones should also be used, so that the potential safety hazards can be reduced during production.Potential safety hazards of planetary reducers: Installed in places with poor environmental conditions, when the inhaled air contains particles, dust, corrosive gases, etc., it will not only affect the service life of the compressor lubricating oil, but may also cause fire related to inhaled particles and explosion accidents.Bappman Industrial Technology recommends that you consider installing an air intake filter, which should be cleaned frequently and replaced regularly.Before using the planetary reducer, the user should first understand the use method and precautions of the planetary reducer. It not only involves the use of the machine itself, but also needs to ensure the safety of the current when using electricity.
- How to ensure the normal operation of the servo planetary reducerThe 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 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
- How to weld and repair the broken shaft of the servo planetary reducerBroken shaft is a common failure of the servo planetary reducer. Many users do not know how to deal with the broken shaft. After a large number of practical cases, the broken shaft of the servo planetary reducer can be repaired by welding. Today I will show you how to weld.The welding is divided into three stages: pre-weld preparation, welding and post-weld treatment. The specific operations are as follows: 1. Pre-weld preparation 1. Welding groove and gap design.The fractured part of the servo planetary reducer should be processed and leveled before welding, and corresponding measures should be taken for the design of the welding groove to reduce the stress.The U-shaped groove is designed according to the fracture condition and the diameter of the part. The upper width of the groove is 20 mm and the depth is 37 mm.After the end surface of the fracture is processed flat, the end surface of the fracture is cut with a formed turning tool to make it consistent in shape.In order to avoid stress concentration, all parts of the groove should be rounded to reduce the proportion of the base metal melting into the weld metal and prevent
- Solve the broken shaft problem of servo planetary reducerWhen the concentricity of the assembly between the drive motor and the reducer is maintained well, the output shaft of the drive motor bears only the rotational force (torque), and the operation will remain smooth without pulsation.When the two are not concentric, the output shaft of the drive motor needs to bear the radial force (bending moment) from the input end of the reducer.The action of this radial force will force the output shaft of the drive motor to bend, and the direction of bending will change continuously with the rotation of the output shaft.If the concentricity error is large, the radial force will also increase the local temperature of the motor output shaft, which will cause the metal structure of the machine parts to be continuously damaged, and eventually cause the output shaft of the drive motor to fail due to local excessive fatigue. break off.The greater the concentricity error between the two, the shorter the time required for the output shaft of the drive motor to break.While the output shaft of the drive motor may be broken, the input end of the reducer will also bear the force from the output shaft of the drive motor.
- Overheating and noise of reducer bearings1. Cause analysis a. Insufficient lubricating oil.When the oil level of the lubricating oil is insufficient or cannot reach a reasonable height due to the oil leakage of the reducer, it may cause the bearing temperature of the reducer to be high or there may be noise; b. The friction of the bearing cover or the sealing part is too large.When the bearing cover or the sealing part and the connecting part are worn due to improper bearing installation, improper bearing cover or long-term use, the temperature of the reducer bearing will be high or there will be noise; c. Bearing damage or wear.It mainly includes the damage of the bearing cage, the wear or deformation of the inner and outer rings, and the wear or drop of the balls, which will make the reducer unable to work normally; d. The bearing clearance is too large or too small.When long-term use causes the gap between the ball of the reducer bearing and the inner and outer rings or the gap between the bearing inner ring and the shaft, and the gap between the bearing and the end cover to become larger, symptoms of bearing overheating noise may appear; e. The helical gear key handle is loose.The looseness of the key handle of the helical gear will cause the mismatch between the gear and the shaft.
- The main characteristics of planetary gear reducer transmission1. Smooth movement, strong shock and vibration resistance: due to the adoption of several planetary gears with the same structure, which are evenly distributed around the center wheel, the forces of the planetary gear and the rotating arm are balanced.The coaxial feature also increases the number of meshing teeth, making the planetary gear drive stable, strong in shock and vibration resistance, and reliable in work.2. The transmission ratio is large, which can realize the synthesis and decomposition of motion: as long as the appropriate type and gear matching scheme are selected, a few gears can be used to obtain a large transmission ratio, up to several thousand.While the transmission ratio is large, it can still maintain the characteristics of compact structure, small mass and small volume.In particular, it should be pointed out that it can also realize the synthesis and decomposition of motion and various complex speed-changing motions.3. The planetary gear reducer is small in size, small in mass, compact and reasonable in structure, and has a carrying capacity: due to the power split of the planetary gear transmission and the coaxial transmission formed by each center wheel, it can be reasonably applied
- Reasons for the gear of the reducer to be stuckDuring the use of the gear reducer, there will occasionally be a phenomenon of stuck teeth. Once this happens, first of all, don’t be impatient. Most of the time it is negligent in the process of using the gear reducer, and the bearings are not lubricated and maintained, which leads to this phenomenon. The next step is to confirm whether this is the case. If it is indeed such a problem, you can directly remove the gear reducer from the machine, clean the bearing and add lubricating oil to avoid similar stuck teeth.Teeth jamming is not only a reason for bearing lubrication, there are usually the following reasons. First, the surface hardness of the gear itself is not enough, and the surface of the gear is damaged and seized after being stressed; There is a problem with the bearing; the third is that there is a problem with the proper lubrication system; and the torque transmitted by the gear exceeds the design capacity.There are many possible reasons.Fourth, the gears and bearings of the reducer are broken, which manifests as noise, excessive clearance, and high temperature.
- Vibration measurement of gear reducerChoice of vibration measurement method There are two measurement methods for the vibration of the gear unit, one is to measure the vibration of the box and the other is to measure the vibration of the shaft.Combining these two measurement methods to obtain the absolute movement of the shaft in the gear unit is also a more effective method.For gear units supported by rolling bearings, the bearing radial clearance is small, and the relative movement between the bearing and the box is also small, so the box vibration measurement should be used.For gear units supported by ordinary sliding bearings, shaft vibration measurement or box vibration measurement can be used.However, when the frequency is in the range of 0-500Hz, the vibration measurement of the box is insensitive and difficult to measure the tiny vibration, so the shaft vibration measurement should be used.The vibration measurement of the box can obtain a wide frequency range and dynamic characteristics, which can provide the necessary basis for the analysis of the meshing frequency of the gear teeth.(2) Vibration measurement of the shaft The vibration displacement of the shaft should be measured relative to the box.Should use non-contact
- Method to relieve internal pressure of planetary reducerWhen the planetary reducer is running at high speed, the temperature and pressure changes in the inner cavity directly affect its load rate, continuous rotation speed and service life.In order to ensure that the input end and output shaft of the planetary reducer are sealed bearings and sealing rings, but the sealed bearings and sealing rings will also affect the temperature and pressure changes in the internal cavity of the reducer.Therefore, under the premise of considering the cost, it is necessary to consider that moderate is to reduce temperature and blood pressure.The temperature and pressure limit the maximum rotation efficiency of the planetary reducer to 98%, and 2% of the input energy is turned into heat and lost.This kind of damage mainly comes from the friction of the sealing ring and the bearing, which will increase the temperature of the inner cavity of the planetary reducer.Sometimes the relatively high natural ambient temperature outside will also increase the temperature of the internal cavity of the reducer.The temperature of the inner cavity of the reducer immediately limits the output torque and output speed ratio.There are many ways to reduce the pressure in the inner cavity of the planetary reducer: one is
