The amount of reducer lubricating oil added needs to be strictly controlled within a reasonable range (usually 1/2 to 2/3 of the oil window or oil dipstick). Too much or too little oil will destroy the normal operation of the reducer and cause the following series of failures: 1. Consequences of adding too much lubricating oil Many people have the misunderstanding that 'the more lubricating oil, the better', but excessive lubrication will bring serious negative effects: abnormal temperature rise: too much lubricating oil will cause the gear to violently agitate the oil during operation, increasing operating resistance and power loss. This severe friction and agitation will generate a large amount of heat, causing the reducer oil temperature to be too high. Exacerbating the risk of oil leakage: Serious splashing of lubricating oil will increase the pressure inside the machine, and a large amount of oil will accumulate in the shaft seal and joint surface. At the same time, the hydraulic pressure will directly impact the oil seal, which can easily cause the seal to deform or even rupture, causing oil leakage. Accelerated component wear: The continued rise in oil temperature will reduce the viscosity of the lubricating oil, causing it to lose its proper lubricity. Read More

Oil leakage occurs soon after the reducer is repaired and installed, which is usually closely related to the process details and improper handling of seals during the assembly process. The following summarizes several core error-prone points in the assembly and sealing process: 1. Irregular cleaning of the joint surface and application of sealant. Incomplete cleaning of the joint surface: When assembling the upper and lower shells, if impurities such as old sealant, iron filings or oil are not completely removed, the joint surface will not fit tightly, forming tiny gaps and causing leakage. In addition, if there are scratches on the joint surface with a depth exceeding 0.25 mm, the sealing effect will be seriously affected. Improper use of sealant: Poor thickness control when applying sealant (reasonable thickness should be controlled between 0.2 to 0.5 mm). If too little glue is applied, it will not be able to seal; if too much glue is applied, it will be squeezed into the inside of the box when the bolts are tightened. After breaking, it will float in the oil, which can easily block the internal oil passage and cause the bearing to lack lubrication. At the same time, it is also common to fail to avoid oil holes, oil grooves and threaded holes when applying glue. Read More

In filling machinery, the reducer is the 'power center' that ensures the synchronous operation of all components. The location of the fault can usually be determined through three main dimensions: 'listening and location identification', 'touch perception' and 'operation test': 1. Analysis from a sound perspective (listening and location identification). Different abnormal sounds often correspond to different internal damages: Harsh friction sound: usually indicates a problem with the gear. It may be that the gears are dry grinding due to insufficient lubricating oil, or the tooth surfaces are severely worn and become rough. Periodic knocking sounds: Regular 'dong-dong' sounds often point to bearing failure. This may be caused by worn bearing balls, broken cage, or improper installation resulting in uneven eccentric force. High-frequency whistling sound: This is mostly caused by an ineffective lubrication system, such as using the wrong type of lubricating oil, too dirty oil, or the oil line is clogged. Sudden breaking sound: This indicates that the gear may have broken teeth or serious cracks, resulting in a high-frequency impact sound. 2.

Filling machinery usually has the characteristics of high-frequency start and stop, continuous operation, and extremely high hygiene requirements. This makes the reducer, as the core transmission component, relatively harsh in working conditions. To effectively extend its service life in the filling machinery, it is recommended to start from five key dimensions: correct installation, standardized installation, scientific lubrication, daily maintenance and environmental control: 1. Ensure that the equipment matches the working conditions and leaves a sufficient safety margin: the filling line will generate a large impact load at the moment of startup or bottle jamming. When Selection, not only the rated torque must be calculated, but the peak torque and radial/axial load must also be checked. It is recommended to retain a safety factor of 1.5 to 2 times to avoid gear fatigue breakage caused by long-term overload. Consider special working conditions: If you are filling corrosive liquids (such as acid-base cleaning agents), you need to choose a reducer with anti-corrosion coating or stainless steel shell; if you are in an explosion-proof workshop (such as alcohol and solvent filling), you must choose explosion-proof motors and reducers that meet the corresponding level. 2 Read More

Brick and tile building materials production lines are usually accompanied by high dust, heavy loads and harsh working conditions of continuous operation. The quality of the reducer is directly related to the stability and efficiency of the entire production line. In view of the core requirements of wear resistance and dust resistance, the following is a systematic purchasing guide for you: 1. Core protection design: Build a solid dust-proof and wear-resistant barrier 1. Box sealing and protection level: Brick and tile factory dust (such as gangue powder, clay powder) can easily invade the gearbox and cause increased wear. A fully enclosed box structure must be selected, and the protection level should reach IP65 and above to effectively block the intrusion of fine dust and prevent lubricating oil leakage. 2. Wear-resistant technology of key components: Important components such as the main shaft of the brick machine and the shaft and gears in the reducer should be made of carbon steel or alloy steel and undergo quenching and tempering or quenching heat treatment processes. Hard tooth surface gears not only have extremely high wear resistance, but can also withstand large extrusion forces and impact loads, ensuring long-term stable operation of the equipment. 3. Coating the scraper and transmission parts Read More

In the robot joint precision reducer Selection, accuracy and backlash are the core indicators that determine the robot's motion quality, positioning accuracy and dynamic response. To scientifically select these two parameters, it is recommended to consider the following dimensions: 1. Clarify the core concepts and application requirements. Backlash (return gap) refers to the tiny angular displacement produced by the output end when a small rated torque in forward and reverse directions is applied to the output end when the input end is fixed. The unit is arcmin (1 degree = 60 arc minutes). The lower the backlash value, the more accurate the transmission, but the corresponding cost is also higher. The first step in selection is to back-calculate the required accuracy level based on the robot's application scenarios: Extremely high-precision scenarios (such as medical surgical robots, semiconductor equipment, precision assembly): Micron-level positioning is required, and a reducer with close to zero backlash must be selected. Harmonic reducers and RV reducers are the first choice, and their backlash is usually ≤1 arc minute. Read More
