Overview
Industrial Geareducers: These advanced components are expertly engineered specifically for cooling towers in expansive industrial and power plant environments. Their innovative design transcends conventional standards, focusing on optimizing air circulation through towers and significantly reducing maintenance challenges, ensuring peak performance.
Gearbox Reducer
Our state-of-the-art Reducer for the second gear transmission showcases a harmonious integration of spiral bevel gear and helical gear transmission systems. This cutting-edge design boasts a compact form, exceptional transmission power, seamless operation, and whisper-quiet functionality. Crafted from 20CrMnTi, each gear undergoes meticulous heat treatment, ensuring remarkable wear and impact resistance. The lubrication system ingeniously combines oil immersion with splash flow lubrication, maintaining optimal oil levels within the casing. An efficient oil disc ensures the smooth flow of oil, lubricating bearings through precision-engineered channels. High-speed shaft entrances are equipped with either a robust skeleton or mechanical seal. After 8,000 hours of continuous operation, it's advised to inspect the seal for wear and determine if replacement is necessary for continued reliability.
The lifting ring screw located on the lid is exclusively designed for lid removal during gearbox maintenance, not for lifting the gearbox itself. Strategically placed control instrument contact screw holes on the box body allow seamless integration with control devices, tailored to the user’s specific needs.
Our cooling tower-specific reducer primarily employs cutting-edge vertical shaft gear transmission while seamlessly incorporating alternative transmission types. The flagship product series include the distinguished M series and H series, each tailored to meet diverse demands.
Design Features:
· Ingeniously crafted design based on precise fan performance parameters and stringent requirements, ensuring unparalleled efficiency.
· Remarkably extended service life of up to 100,000 hours, with an impressive service factor of KA=2.
· Comprehensive strength calculations and meticulous verification for load-bearing components, including gears, shafts, and keys, along with a thorough assessment of bearing load capacity and longevity.
· Innovative splash lubrication system complemented by a self-lubrication mechanism for sustained performance.
· Our helical gears strictly adhere to GB/T 3480 'Strength Calculation of Involute Gears', and our spiral bevel gears conform to GB/T 10062 'Calculation Method for Load-Capacity of Bevel Gears', ensuring unmatched reliability.
· A visionary modular design featuring a variety of materials and standard components to satisfy an array of customer specifications.
· A precision-engineered, optional forced cooling system, designed to maintain accurate oil temperature control, even under the most extreme conditions.
