II. Core Advantages: Five Heavy-Duty Transmission Strengths, Defining Universal Load-Bearing Standards
1. Heavy-Duty Universal Cabinet, Multi-Attitude Stable Installation
The series adopts a heavy-duty universal integrated cabinet structure optimized by bionic topology and finite element analysis, and the cabinet is made of high-strength cast iron (HT300) with thickened wall thickness (15% thicker than ordinary models) and dense reinforcing rib distribution, ensuring ultra-high structural rigidity while realizing multi-attitude stable installation. The six core models cover diversified input-output attitudes to meet extreme heavy-duty equipment layout needs: WPWK (standard heavy-duty universal type), WPWKA (heavy-duty universal type with input shaft downward), WPWKS (heavy-duty universal type with input shaft upward), WPWKO (heavy-duty universal type with output shaft upward), WPWKV (heavy-duty universal type with input shaft vertical), WPWKT (heavy-duty universal type with output shaft vertical). The cabinet is equipped with reinforced mounting flanges and precision positioning holes on multiple sides, which can flexibly switch between horizontal, vertical, wall-mounted, ceiling-mounted and other installation modes. The installation positioning accuracy error is ≤0.1mm, and the mounting base is designed with anti-vibration gaskets, which effectively ensures the stable operation of the transmission system under heavy-load vibration conditions.
2. Enhanced Worm Gear Transmission, Strong Load-Bearing & Impact-Resistant
The series adopts enhanced heavy-duty worm gear transmission pair design, the worm is made of 42CrMo high-strength alloy steel, processed by integral forging, quenching and tempering, and super-precision grinding, with surface hardness up to HRC 62-65 and tooth surface roughness ≤Ra 0.3μm. The worm gear is made of high-wear-resistant nickel bronze (ZCuNi10Pb1) with thickened tooth thickness and precision tooth profile modification, and the meshing contact area reaches more than 93%, realizing uniform force transmission under heavy load. The worm shaft adopts large-diameter integral rigid design, and the bearing adopts high-load tapered roller bearings with double-sided sealing, which improves the shaft system bearing capacity by 60% compared with servo-specific models. The transmission accuracy error is ≤0.2arcmin, and the transmission system can bear 3 times the rated torque impact, with stable transmission accuracy deviation ≤0.25arcmin, which can perfectly match the heavy-load impact working conditions of mining, construction and other industries. The no-load operating noise is ≤58dB, and the load operating noise is ≤65dB (measured at 1m distance), ensuring relatively quiet operation under heavy load.
3. Flexible Power Matching, Wide-Range Adaptation
The series supports flexible power source matching, and all models are equipped with standard motor flanges (compatible with IEC standards) that can be directly matched with 1.5-75kW standard three-phase asynchronous motors, high-power variable frequency motors and explosion-proof motors. For special heavy-duty scenarios, it can be customized with reinforced flange structures and input/output shaft extension designs to meet the matching needs of high-power heavy-duty motors. The flange and cabinet are integrally cast with coaxiality error ≤0.03mm, avoiding transmission efficiency loss caused by assembly errors. This flexible matching design not only improves the product's versatility and adaptability to different heavy-duty working conditions, but also reduces the user's equipment procurement cost and debugging cycle, and simplifies the overall assembly process of heavy-duty equipment.
4. Multi-Layer Sealing & Efficient Heat Dissipation, Harsh Environment Adaptation
The sealing system adopts enhanced four-layer protection design: outer layer stainless steel labyrinth seal + middle layer high-temperature resistant double-lip oil seal + inner layer O-ring + bottom layer anti-dust cover, with high-temperature resistant and corrosion-resistant sealant at the cabinet joint, achieving IP66 protection level and customizable IP68 protection level for special harsh environments. It can effectively prevent the intrusion of dust, sludge, corrosive media and other impurities in mining, construction and other harsh industrial environments, and avoid lubrication failure caused by oil leakage. The cabinet is designed with integral heat dissipation fins, and the heat dissipation area is increased by 40% compared with ordinary models. It adopts optimized forced circulation lubrication, and the built-in high-precision oil filter and oil cooler ensure the cleanliness and temperature stability of lubricating oil. Using 220#/320#/460# special heavy-duty synthetic worm gear oil, the product can work normally in the operating temperature range of -30℃ to +120℃, adapting to extreme temperature difference environments.
5. Long Service Life & Low Maintenance, Cost-Saving Operation
The key components of the product adopt high-wear-resistant and high-temperature resistant materials, and the worm gear and worm undergo special surface treatment to improve wear resistance and corrosion resistance. The rated service life reaches more than 15 years under normal maintenance conditions, and the maintenance cycle is extended by 60% compared with ordinary models. The centralized oil filling port, large-diameter oil drain port and transparent oil level observation window facilitate daily lubrication management and maintenance operations. The product has strong fault tolerance and can maintain stable operation for a short time under slight misalignment or impurity intrusion conditions, reducing the frequency of unexpected shutdowns of heavy-duty equipment. The overall maintenance cost is reduced by 35% compared with similar heavy-duty models, significantly saving the user's operation and maintenance costs.

V. Installation and Maintenance: Scientific Operation, Maximizing Performance
During installation, select the corresponding model according to the equipment layout (input/output shaft attitude) and load-bearing requirements. For heavy-duty installation scenarios, ensure that the coaxiality error between the reducer and the power source is ≤0.1mm, and use reinforced mounting brackets to fix firmly to avoid vibration during operation. For models matched with explosion-proof motors, ensure that the connection parts are sealed and isolated in accordance with explosion-proof requirements. Select the appropriate lubricating oil according to the working conditions: use 220# special synthetic worm gear oil for normal temperature and general load, 320# for high temperature and heavy load, and 460# for ultra-heavy load and low temperature. Regularly check the oil level, oil quality, sealing performance and heat dissipation status; replace the lubricating oil after the first 2000 hours of operation, and perform comprehensive maintenance every 5000 hours thereafter, including checking worm gear meshing status, bearing temperature, fastener tightness and heat dissipation fin cleanliness. If abnormal phenomena such as excessive noise, vibration, oil leakage or overheating occur during operation, stop the machine immediately for inspection and troubleshooting.
