- How to repair uneven wear of ZD series soft tooth surface gear reducerTo repair uneven gear wear of ZD gear reducer, you need to follow the process of 'diagnose the root cause first - then repair according to the situation - and then prevent recurrence'. The specific operation steps are as follows: 1. Accurately locate the root cause of wear (1) Shut down and cut off the power, remove the reducer end cover and bearing end cover, take out the gear set, and check the worn parts: common uneven wear locations are one side of the gear tooth surface, tooth top or part of the tooth root. (2) Investigate core incentives: ① Installation deviation, the coaxiality of the input shaft and the output shaft is out of tolerance, or the connection with the motor and load is not concentric; ② Lubrication failure, inconsistent lubricant grade, insufficient oil volume, and oil contamination, leading to rupture of the lubricating film on the tooth surface; ③ Abnormal load, long-term unbalanced load, impact load or overload operation causes uneven stress on the gear; ④ Bearing damage, excessive bearing clearance or stuck, causing gear axis deviation; ⑤ Gear manufacturing defects, insufficient tooth profile accuracy, and uneven tooth surface hardness. (3) Record the degree of wear and tear
- What additional maintenance is required for CJY shaft-mounted reducer under special working conditions?The additional maintenance of CJY shaft-mounted reducer under special working conditions needs to be combined with the characteristics of the working conditions, and targeted strengthening of lubrication, sealing, cleaning, monitoring and other links. The following are additional maintenance measures for different special working conditions: 1. Heavy load/impact load conditions (such as metallurgy, mining equipment) (1) Shorten the lubricating oil replacement cycle: from the conventional 6~12 months to 3~4 months. Thoroughly clean the inner wall and oil passage of the gearbox during each oil change to avoid tooth surface wear caused by accumulation of iron filings and impurities. (2) Strengthen tooth surface lubrication protection: Use extreme pressure industrial gear oil (such as L-CKD 220 or 320), and add gear anti-wear agent to improve the tooth surface load-bearing capacity and prevent tooth surface gluing and pitting corrosion. (3) Increase the frequency of fastener inspections: Check the connecting bolts of the input shaft, output shaft and coupling every week, as well as the fastening bolts of the reducer installation base, and use a torque wrench to retighten according to the standard torque to prevent loosening of the bolts.
- How to judge whether the GSAF77-Y2.2-4P-130-M5 reducer is well lubricatedTo determine whether the GSAF77-Y2.2-4P-130-M5 reducer is well lubricated, it can be comprehensively determined through three methods: operating status observation, oil detection, and component inspection. The specific points are as follows: 1. Operating parameters monitor oil temperature: Under normal working conditions, the reducer housing temperature should be stable within 60°C, with a maximum of no more than 80°C; if the oil temperature continues to be high without the influence of external heat sources, the most likely cause is insufficient lubrication, oil deterioration, or oil model mismatch. Vibration and noise: When the lubrication is good, the operating vibration amplitude is stable and within the factory standard range of the equipment, and the noise is a uniform meshing sound; if there is an abnormal sharp sound and the vibration amplitude suddenly increases, it may be poor lubrication that leads to increased gear or bearing wear. Running resistance: Manual cranking when stopped, the hand feels smooth without stuck or obvious frustration; if the cranking is laborious, it is necessary to check whether the frictional resistance of the components is increased due to lack of oil or abnormal oil viscosity. 2. Oil
- What are the differences in lubricating oil requirements for different types of reducers?The differences in lubricating oil requirements of different types of reducers are mainly determined by four core factors: transmission structure, working condition parameters, sealing form, and installation method. The specific differences can be listed according to the following dimensions: 1. Differentiate gear reducers according to transmission type (such as cylindrical gears, bevel gears, and helical gear reducers): it is necessary to focus on load-bearing and wear resistance, and the medium-sized ones are preferred. / Heavy-duty industrial gear oil (L-CKC/L-CKD series), the viscosity needs to match the gear module and operating speed; select high-viscosity oil (460#, 680#) for heavy-duty gears with large module and low speed (such as crane reducers), and low-viscosity oil (150#, 220#) for high speed and small load. Worm gear reducer: Most worm gears are made of copper. It is necessary to avoid the active sulfur additives in the oil from corroding the copper parts. Special worm gear oil (L-CKE/P series) or gear oil without extreme pressure additives; and because the worm drive has large sliding friction and heat,
- Does the preheating operation have any impact on the service life of the NGW83-1-180 planetary reducer?Preheating operation has a significant positive impact on the service life of the NGW83-1-180 planetary reducer. Scientific and standardized preheating can significantly reduce component damage under low-temperature conditions and extend the service life of the entire machine. On the contrary, non-standard preheating or starting without preheating will increase wear, induce embrittlement failure, and shorten the life of the equipment. Specifically, it can be analyzed from the following four core dimensions: 1. Reduce low-temperature cold start impact load and reduce gear meshing damage NGW83-1-180 It is a medium-to-heavy planetary reducer. The core gear is made of alloy steel. It is suitable for use in low-temperature environments (especially - 10℃ or below) the material toughness will significantly decrease and the elastic modulus will increase. At this time, it will be started directly at full load. The meshing of the planet gear, sun gear and internal ring gear will produce 2-3 Impact stress that is times the rated load. Standard preheating can make the temperature of the box and core components rise to 10-20℃, restore the impact toughness of the material, and at the same time make
- From what dimensions can the oil monitoring data reflect whether the NGW122-35.5 reducer needs to be preheated?The oil monitoring data can accurately determine whether the NGW122-35.5 reducer needs to be preheated from the five core dimensions of viscosity characteristics, temperature response, abrasive particle characteristics, moisture and contamination, and oil physical and chemical decay. Each dimension can reflect the risk of lubrication and startup at low temperatures, as follows: 1. Low temperature viscosity and viscosity change rate dimensions are the core indicators for judging whether preheating is needed. The viscosity of lubricating oil will rise sharply at low temperatures. For NGW122-35.5 medium and heavy-duty planetary reducers, if the actual measured kinematic viscosity at 40°C deviates by more than +20% from that of new oil (for example, the viscosity of ISO VG 220 oil rises to 300cSt or more), or the dynamic viscosity at -10℃ exceeds 10000mPa·s will lead to poor oil fluidity during startup, making it difficult for gears and bearings to form an effective oil film, causing dry friction and startup shock.

- How about RV series worm gear reducer SelectionThe RV series worm gear reducer Selection needs to follow the three core principles of 'working condition priority, parameter matching, and safety redundancy', and gradually determine the model according to the following steps to ensure that it adapts to actual application needs: 1. Clarify the core working condition parameters (1) Load torque: Calculate the output load torque (including rated load, impact load) under actual working conditions, the formula is =9550, where is the motor power (kW) and is the reducer transmission efficiency (RV) The series is usually 0.4-0.7, the smaller the reduction ratio, the higher the efficiency), which is the output speed (r/min). It is necessary to reserve 1.2-1.5 times the impact coefficient (1.5 for high-frequency start-stop and heavy-load conditions). (2) Speed requirement: Determine the motor input speed (usually 1450r/min) and the required output speed of the equipment, calculate the reduction ratio, and give priority to the standard reduction ratio of the reducer (such as 5, 10, 20, 40, 100, etc.). (3)Installation party
