The maintenance of the cooling system of the ZSC750-34.4-1 gear reducer requires systematic management around four aspects: oil level control, oil change cycle, sealing structure design and operation monitoring. The following are specific maintenance methods: Oil level control The oil level is the basis of the cooling system and needs to be checked regularly and maintained at the centerline of the oil window or oil mark. For vertically installed reducers, the oil level should ensure that the gear is immersed in 1/2~2/3 of the tooth width to avoid excessive oil level increasing oil stirring resistance or too low oil level resulting in insufficient lubrication. The inspection needs to be carried out after the equipment is shut down and cooled down to ensure accurate readings. Oil change interval: The lubricating oil needs to be replaced after the first operation of a new reducer for 150-300 hours to remove metal debris generated during the running-in period. The regular oil change interval is every 6-12 months or 2000-3000 cumulative operating hours (whichever comes first)‌. If the oil color becomes black, turbid or metal debris appears, the oil needs to be changed in advance. When changing oil, use Read More

As a ZSC series cylindrical gear reducer, the oil pool design of ZSC350 - 17.2 - 2 conforms to the commonly used oil pool splash lubrication method of this series, focusing on lubrication reliability, impurity precipitation, heat dissipation and maintenance convenience, and adapting to its own transmission working conditions. The specific features are as follows: 1. Oil immersion depth adapts to splash lubrication requirements: This type of reducer is likely to use two-stage gear transmission, and the oil pool depth has been accurately measured to control the oil immersion depth of the final large gear within a reasonable range. Usually the oil immersion depth is one tooth height and not less than 10mm, it can not only meet the lubrication requirements during gear meshing, but also smoothly bring up oil to form oil mist and oil flow when the gears rotate, providing lubrication for gears and bearings at all levels; it can also avoid excessive oil immersion, which will lead to excessive oil stirring power consumption when the gear rotates, and prevent insufficient lubrication due to shallow oil immersion. At the same time, the distance between the tooth tip circle and the bottom of the oil pool is not less than 30-50mm Read More

The impact of drying method on the life of DBY180-6 reducer is mainly reflected in the damage of high temperature to the lubrication system and core components. The following is a specific analysis: 1. Risk of lubrication system failure. High-temperature drying will directly destroy the lubrication system of the reducer. This is the top priority problem: ‌ Lubricating medium viscosity decreases ‌: When the temperature exceeds 60°C, the viscosity of the grease or gear oil will decrease significantly, causing the oil film to rupture and the metal surface to directly contact and rub, forming a vicious cycle of 'high temperature → viscosity decrease → friction intensification → higher temperature'. ‌Oxidative aging of lubricating media‌: High temperature will accelerate the oxidation reaction of grease, generate organic acids and hard impurities, corrode metal parts and increase wear‌. ‌Leakage of lubricating medium‌: If the temperature exceeds the dropping point of the grease (approximately 120°C for ordinary lithium-based grease), the grease will turn into liquid and leak, causing dry wear of the transmission parts, which may cause tooth surface ablation or bearing jamming in the short term. 2. Damage to key components Read More

The core lubrication method of ZSC (A) 400-24.9-2 medium hard tooth surface reducer is oil bath lubrication (splash lubrication). The regular oil change interval is 200~300 hours for the first operation, and every 2000~3000 hours or once a year thereafter. 1. Main lubrication methods Core methods: oil bath lubrication (splash lubrication), the gear is immersed in the lubricating oil pool, and when rotating, the oil is brought up to form an oil film, which lubricates key parts such as meshing surfaces and bearings. Supplementary scenario: If the installation angle of the reducer is >15°, continuous heavy load or high temperature environment, forced circulation lubrication (external oil pump) can be used to improve lubrication uniformity. Lubricating oil selection: commonly used 220# and 320# medium-load industrial gear oil (GB 5903 standard), 150# can be selected for low temperature environments, and 460# can be selected for high temperature and heavy loads. 2. Standard oil change cycle: First oil change: the new reducer runs for 200 to 300 hours and needs to be replaced in time. Read More

To optimize the WPDA60-20-0.37KW reducer lubrication system to reduce vibration, the core is to 'select the right oil, control the oil well, and protect the oil well' to form a stable oil film on the meshing surface and bearings to reduce friction and impact. The specific methods are as follows: 1. Precisely match the lubricant and build a solid lubrication foundation. Select the right oil model: Prioritize the use of special oil for worm gears (such as L-CKC 220#, choose 150# for low temperature conditions, and choose 320# for high temperature and heavy loads). Its additives can improve the anti-gluing and anti-wear properties, and are more suitable for the copper-steel meshing worm gear structure than general mechanical oil. Confirm material compatibility: If the seal is nitrile rubber, avoid using oil containing too many extreme pressure additives; fluororubber seals can be adapted to most special oils to prevent oil contamination and lubrication failure caused by reaction between the oil and the seal. Control the oil viscosity: the viscosity needs to match the working conditions. If the ambient temperature is 10-40°C, choose 220#, which is lower than 1 Read More

The resonance frequency of the DCY160-31.5-1 gear reducer has a significant impact on its performance and life. The specific manifestations are as follows: 1. ‌The impact of resonance on structural integrity‌When the operating frequency of the reducer is close to its natural frequency, resonance will occur, causing the box, gears and other components to bear excessive alternating stress. For example, measured data shows that axial vibration with a sustained acceleration of more than 3g can reduce the bending fatigue strength by 25%-30%‌. If the resonance displacement of the box support exceeds 0.045mm, the contact stress on the gear meshing surface may exceed the strength threshold of 160MPa, accelerating the initiation of cracks. 2. ‌The acceleration effect of resonance on gear fatigue life‌Resonance will amplify the alternating stress at the gear tooth root, increase the stress concentration of surface defects by 8 times, and significantly shorten the fatigue life‌. In particular, the second to fourth order harmonic vibration components (such as 0.8-1.2 times the meshing frequency) may cause micro pitting corrosion on the tooth surface to evolve into macro Read More
