2. Dual-Series Silent Energy-Saving Graded Configuration, Precise Intelligent Heavy-Duty Adaptation

The six core models of the series are divided into SV and SV-B dual silent energy-saving series with targeted graded configuration to meet differentiated intelligent heavy-duty transmission needs: SV-series models (H2SV, H3SV, H4SV) are silent energy-saving standard heavy-duty models, integrating silent transmission and energy-saving optimization structure, suitable for intelligent heavy-duty equipment such as automated mining conveyors, intelligent production line auxiliary machinery and medium-sized port intelligent hoists; among them, H2SV is small-medium torque silent energy-saving model, H3SV/H4SV are large torque silent energy-saving enhanced models. SV-B-series models (B2SV, B3SV, B4DH) are ultra-heavy load silent energy-saving enhanced models with reinforced shaft, thickened gear, high-strength bearing and intelligent monitoring interface design, ideal for ultra-heavy-load intelligent equipment such as large-scale intelligent mining excavators, heavy port intelligent container cranes, high-load intelligent construction machinery main transmission systems and precision metallurgical smelting auxiliary machinery. This dual silent energy-saving series graded design ensures precise matching of different heavy load levels, noise requirements and intelligent adaptation needs, further improving equipment operation stability, energy efficiency and intelligence level in intelligent production environments.

3. High Torque Bearing Capacity, Durable Intelligent Heavy-Duty Operation

Gears and transmission shafts are made of high-strength 42CrMo alloy steel with friction-reducing strengthening treatment (SV-series) and 40CrNiMoA ultra-high-strength alloy steel with silent optimization heat treatment (SV-B-series), processed through precision forging, carburizing, quenching, tempering, precision grinding, polishing and surface friction-reducing coating processes. The surface hardness reaches HRC 62-65, and the core hardness is HRC 35-38, ensuring excellent wear resistance, impact resistance, fatigue resistance and silent torque transmission stability. The optimized gear modulus, tooth width, shaft diameter and silent structure design for each model ensures that the rated output torque of the series is precisely graded from 1200N·m to 35000N·m (H2SV: 1200-3000N·m; H3SV: 3000-10000N·m; H4SV: 10000-26000N·m; B2SV: 14000-24000N·m; B3SV: 24000-32000N·m; B4DH: 32000-35000N·m). The integral cast iron housing with high rigidity, thickened wall and sound insulation design ensures no deformation under ultra-heavy load, ensuring a service life of more than 15 years under normal maintenance in intelligent heavy-duty environments.

4. Modular Intelligent Heavy-Duty Installation, Flexible Layout Adaptation

The series adopts an upgraded intelligent heavy-duty modular design, supporting multiple installation modes such as base-mounted, flange-mounted (B5/B14), torque arm-mounted, shaft-mounted, flange-output mounted and mobile base-mounted, which can be flexibly selected according to the diversified layout requirements of intelligent heavy-duty industrial equipment. The output shaft is configured with ultra-heavy-duty silent reliable options such as extra-large-diameter solid shaft with flat key, high-strength spline solid shaft, extra-large-torque hollow shaft with locking disk and friction-reducing sleeve-equipped shaft, and is equipped with standard intelligent monitoring interfaces (such as temperature, vibration, torque monitoring) to realize seamless connection with intelligent control systems. It can be precisely matched with motors with power ranging from 4kW to 300kW and reduction ratios of 5-400 (single-stage/multi-stage combination). The standardized ultra-heavy-duty interface design with reinforced connection parts and dust-proof protection facilitates quick installation and replacement in intelligent workshops and outdoor intelligent sites, reducing construction difficulty and time cost, and adapting to the layout needs of various intelligent core heavy-duty industrial equipment.

During installation, ensure that the coaxiality error between the reducer and the motor is ≤0.1mm to avoid affecting transmission stability, silent performance, energy-saving effect and ultra-heavy load-bearing capacity. For ultra-heavy-duty, high-vibration and intelligent monitoring environment installation, adopt reinforced concrete installation base with shock-absorbing layer and high-performance shock-absorbing pads to reduce vibration impact and noise. Connect the intelligent monitoring interface with the control system correctly to ensure real-time monitoring of temperature, vibration and torque parameters. Select the appropriate lubricating oil according to the working conditions: use 320# silent energy-saving ultra-heavy-duty industrial gear oil for normal temperature and medium-heavy load, 460# for high temperature and heavy load, and 680# for ultra-high load, high-temperature and continuous intelligent operation. Regularly check the oil level, oil quality, gear meshing status, fastener tightness, heat dissipation fin cleanliness and oil filter blockage; replace the lubricating oil after the first 1000 hours of operation, and perform comprehensive maintenance every 5000 hours thereafter for intelligent continuous working conditions, including checking bearing temperature, sealing performance, housing deformation, gear wear and friction-reducing coating integrity. If abnormal phenomena such as excessive noise, obvious vibration, oil leakage, overheating, torque fluctuation or abnormal monitoring data occur during operation, stop the machine immediately for inspection and troubleshooting.
