To prevent vibration of the motor and ZDY250-2.5-1 reducer, we need to start from three aspects: 'basic calibration + component maintenance + operation monitoring'. The core is to control the level and coaxiality to eliminate the source of vibration. 1. Accurately calibrate basic parameters (core preventive measures). Strictly control the level. Calibrate the base and axis of the motor and reducer according to the standard of ≤0.05mm/m to avoid vibration caused by uneven force. To ensure that the coaxiality reaches the standard, use a laser alignment instrument or feeler gauge to detect the coupling to ensure that both radial and angular deviations are ≤0.1mm to reduce transmission shock and vibration. Fix the base firmly, and tighten the anchor bolts evenly to the specified torque. If necessary, install anti-loosening washers to prevent loosening during operation of the equipment and amplification of vibration. 2. Standardize the maintenance of key components, check the coupling regularly, and promptly replace aging and damaged elastic sleeves, plum blossom pads and other buffer parts to avoid vibration caused by rigid impact. Ensure lubrication is in place according to equipment requirements Read More

When selecting the motor model of the reducer, the core is to match the rated input power, speed and installation conditions of the reducer. The specific steps and Selection suggestions are as follows: 1. Clarify the core matching parameters of the reducer. Rated input power: The rated input power of WHC120-40-3 is about 7.5KW (corresponding to an output torque of about 1200N.m). The motor power must be ≤ this value to avoid overload damage to the reducer. Adaptable speed: The recommended input speed of the worm gear reducer is 1450r/min (conventional 4-pole motor speed). When paired with a speed ratio of 40, the output speed is about 36r/min, which meets the needs of most medium and low-speed working conditions. Installation interface: Confirm the input shaft diameter of the reducer (normally 18-22mm) and keyway size, and the motor output shaft needs to match it, or adapt it through a coupling. 2. Core points of motor model Selection 1. Power Selection: 7.5KW motor (full equipped with reducer rated Read More

To adjust the level of the motor and the ZDY160-2-11 reducer, you need to follow the process of 'detecting deviation → step-by-step adjustment → review and fixation', focusing on ensuring that the base and axis are bi-level and coaxial. 1. Before adjustment, prepare to clean the equipment base and installation surface, remove oil dirt, debris and bulges, and ensure that the contact surface is smooth and free of gaps. Check whether the anchor bolts and pads are intact, and prepare tools such as a level (recommended 0.02mm/m frame or electronic level), adjustment pads, thin steel sheets, and torque wrenches. Preliminarily fix the equipment, do not tighten the anchor bolts temporarily, and leave room for adjustment. 2. Step-by-step adjustment operation: First calibrate the level of the reducer, place the level on the base plane of the reducer and the end face of the input shaft, and detect the longitudinal and transverse levels respectively. Correct the reducer deviation by increasing or decreasing the adjustment horn or tapping the precision inclined horn until the level bubble is centered (or the electronic level displays a deviation of ≤0.02mm/m).

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
