The core of the working principle of the NCZD500-1250-1 planetary gear reducer is planetary gear train meshing transmission, which achieves an ultra-large reduction ratio through the synergy of the sun gear, planetary gear, and internal ring gear; its performance advantages revolve around 'ultra-large transmission ratio, ultra-high torque, and high stability', making it perfectly suitable for ultra-heavy and low-speed working conditions. 1. Working principle: Three-stage meshing transmission of planetary gear train. This reducer is a single-stage planetary transmission structure ('1' in the model represents 1st stage). Through the transmission path of 'sun gear active→planetary wheel rotation→planetary carrier output', the high speed of the motor is converted into low speed and high torque. The specific process is divided into 3 Step: Power input: The sun gear receives power and the output shaft of the motor is rigidly connected to the sun gear of the reducer. After the motor is started, it drives the sun gear to rotate at high speed (for example, the motor speed is 1500r/min). The sun gear serves as the driving wheel and drives the surrounding 3-4 wheels through tooth surface meshing. Read More

To clean the cooling fan of the WPDKS155-60-4KW worm gear reducer, you need to follow the process of 'power outage safety → cleaning by parts → inspection and reset'. The core is to completely remove dust and oil while avoiding damage to the fan components to ensure that the cooling efficiency is restored after cleaning. 1. Preparation before cleaning: Clarify tools and safety precautions. Tool preparation and safety protection must be done before cleaning to avoid electric shock or component damage. Tools and materials list Basic tools: Phillips screwdriver (used to remove the fan guard), compressed air gun (pressure ≤ 0.4MPa, used to blow away dust), soft brush (made of nylon, soft brush head to avoid scratching the fan), rag (pure cotton cloth without fiber shedding, can be dipped in a small amount of neutral detergent, such as detergent dilution). Protective equipment: insulating gloves (to prevent electric shock), goggles (to prevent dust from splashing into the eyes). If the fan is heavily oily, oil-resistant gloves are required. Safety precautions must be cut off first Read More

To replace the cooling fan of the WPDKS80-30-1.5KW worm gear reducer, you need to follow the process of 'safe power off → remove the old fan → match the new fan → install and reset'. The core is to ensure that the wiring is correct and the installation is firm to avoid heat dissipation failure due to model mismatch or improper installation. 1. Preparation before replacement: Confirm the model and tools to ensure safety. Confirm the fan model and parameters. First record the key parameters of the old fan (to avoid buying by mistake): Voltage: usually AC220V Or 380V (check the fan motor nameplate, which is consistent with the power supply of the reducer); power: mostly 15-40W (low power fan, too large may cause circuit overload); installation dimensions: fan outer diameter (usually Φ80-120mm), fixed hole spacing (hole center distance, such as 4-M4 screw holes, spacing 50mm), shaft length (if it is a shaft-mounted fan). If the nameplate is unclear, please refer to the reducer description. Read More

Worm gear reducers need to meet strict hygienic requirements in the food industry, which are mainly achieved through the following design and use specifications: 1. Material and structural design‌Food-grade materials‌Parts in contact with food must be made of stainless steel (such as 304 or 316L) or non-toxic coating materials to avoid heavy metal precipitation and microbial growth. The tooth surface of the worm gear needs to be smoothed to reduce residue accumulation. ‌Sealing and Protection‌It must be equipped with a sealing structure with IP65 or above protection level to prevent lubricating oil leakage and the intrusion of external pollutants. The output shaft adopts labyrinth seal or double lip seal to avoid food contact with grease. 2. Lubrication management ‌ Food grade lubricants ‌ must use NSF H1 certified grease to ensure it is non-toxic and meets food contact safety standards. The lubrication system must be designed to facilitate cleaning and oil change to avoid residues. ‌Lubrication maintenance specifications‌The lubricating oil needs to be replaced after the first 400 hours of operation, and every 5,000 hours thereafter or when the oil temperature exceeds Read More

1. Core judgment basis: Load and working condition requirements‌Carrying capacity‌Hard-tooth surface reducer (tooth surface hardness ≥350HBS) has a high single-tooth bearing capacity and can withstand impact loads. It is suitable for heavy-load applications such as mining equipment and cranes. Soft tooth surface reducers (tooth surface hardness ≤350HBS) have low load-bearing capacity and are suitable for light-load scenarios such as agricultural machinery and logistics equipment. Long-term heavy loads can easily cause tooth surface deformation. ‌Speed ​​and Efficiency‌The hard tooth surface has high transmission efficiency (85%-95%) and is suitable for high-speed scenarios (such as machine tool spindle drive). The efficiency of soft tooth surface is low (70%-85%). Due to the large friction loss, it is more suitable for low-speed equipment (such as conveyor belts). 2. Differences in materials and processes ‌Hard tooth surface‌ material: high-strength alloy steel (such as 20CrMnTi). After carburizing, quenching, gear grinding and other processes, the tooth surface hardness reaches 58-64HRC. The process is complex and the cost is high (50%-80% more expensive than soft tooth surface), but the service life is as long as 10-1 Read More

The output speed of SA47-15-1.5KW worm reducer is 'Transmission ratio''Motor input speed''Actual operating condition loss' It is determined by three core factors, among which the transmission ratio and motor input speed are the basis for theoretical calculation, and the working condition loss is the correction term in actual operation. The following is a disassembly analysis of specific influencing factors, combined with model parameters ('SA47' is the frame number, '15' is the nominal transmission ratio, '1.5KW' is the matching motor power) Explanation: 1. Core determinants: transmission ratio ('fixed coefficient' of theoretical output speed) The output speed of the worm reducer is essentially 'motor input speed ÷ transmission ratio', where the transmission ratio is fixed and determined by the mechanical structure of the reducer (number of worm heads, number of worm gear teeth), and is the core and most stable factor affecting the output speed. 1. Definition and calculation of transmission ratio Logical transmission ratio (i) is the reducer Read More
