Cylindrical gear reducers are a type of reduction device using cylindrical gear transmission, achieving torque transfer and speed regulation through multi-stage gear meshing. Its core structure includes a high-speed input shaft, a low-speed output shaft, and multiple sets of cylindrical gear assemblies (such as spur gears, helical gears, or herringbone gears). The gears are usually made of high-quality alloy steel and undergo carburizing and quenching treatment to ensure high wear resistance and fatigue strength. The reducer housing is mostly made of cast iron or cast steel, providing good rigidity and sealing, suitable for power transmission scenarios from medium to heavy loads.
Product Applications
Lifting and transportation equipment: port gantry cranes, tower cranes, belt conveyors, etc., achieving speed control for heavy lifting and horizontal transportation.
Mining machinery: crushers, hoists, scraper conveyors, suitable for harsh environments with heavy dust and high impact loads.
Metallurgical industry: steel rolling production lines, continuous casting machines, heating furnace exhaust fans, meeting transmission needs for high temperature and continuous operation.
Chemical equipment: reactor agitators, material mixers, compatible with explosion-proof modifications and corrosion-resistant environments.
Construction machinery: excavator slewing mechanisms, paver traveling systems, providing highly stable power output.
Product Features
High efficiency transmission: gear meshing efficiency over 97%, reducing energy loss;
High load capacity: module range 4-12mm, allowable torque up to 1000kN·m, suitable for heavy load impacts;
Smooth operation: helical gear design reduces noise (≤85dB), vibration value <4.5mm/s;
Compact and reliable: standardized center distance design (80-800mm), housing reserved with multiple mounting interfaces;
Long service life: designed lifespan over 15 years, bearings use imported brands (SKF/NSK), grease lubrication maintenance-free.
Product Functions
Speed regulation: precise output speed control by adjusting gear transmission ratio (i=3-100);
Torque amplification: converting low motor torque into high torque output to meet equipment starting and overload requirements;
Direction change: achieving 90° direction change through gear arrangement (e.g., vertical installation conditions);
System integration: can be combined with motors, couplings, and brakes to form a reduction drive unit, simplifying the transmission chain.
