In many cold zones and high-latitude areas, ordinary gearboxes often cannot withstand extreme low-temperature environments, and frequently encounter problems such as difficulty in starting, lubrication failure, and even mechanical failure. In the face of these challenges, DongHai's -40°C low-temperature gearbox came into being. It is not only a guarantee for the stable operation of equipment, but also an ideal choice to help companies reduce costs, increase efficiency, and extend the life of equipment.
This -40°C low-temperature gearbox has been fully optimized for extremely cold environments since its design. The shell part is made of high-strength iron or aluminum alloy, which has excellent pressure resistance and toughness and can maintain structural stability and no deformation even in extreme environments of minus 40°C. The internal gears are carburized and quenched heat-treated, which greatly improves the hardness and wear resistance. In addition, the specially designed low-noise tooth structure effectively reduces the noise and vibration during equipment operation, ensuring that the equipment runs more smoothly and quietly.
The lubrication system is one of the most core difficulties of the low-temperature gearbox. Conventional lubricants will quickly thicken or even fail at low temperatures, causing increased gear wear and seriously affecting the life of the equipment. DongHai has equipped this with special low-temperature grease, which not only ensures that the gearbox is well lubricated in sub-zero environments but also does not require lubricant replacement for 20,000 hours under normal operating conditions, significantly reducing maintenance costs and downtime risks.
In terms of sealing, this low-temperature gearbox also uses high-performance sealing materials developed specifically for low-temperature environments. Compared with ordinary seals, it is not easy to harden or crack at low temperatures, can effectively prevent lubricant leakage, and keep the inside of the gearbox clean and dry. At the same time, in order to ensure that the equipment can be started smoothly in extremely cold areas, the product can also be equipped with a heating device or an auxiliary starting system, which can operate stably even in severe cold weather, without worrying about the equipment being "frozen" or lagging.
From the user's perspective, choosing this low-temperature gearbox not only means higher operating efficiency (up to 92%-96%), lower energy consumption and noise, but also means a longer trouble-free operation cycle, fewer on-site maintenance times, and stronger environmental adaptability. For many users in wind power, photovoltaic power, mining, cold chain logistics, and other industries located in high-altitude, extremely cold, or long-winter areas, this product will greatly reduce operating costs and improve the equipment's year-round attendance rate.
At present, DongHai's -40℃ low-temperature gearbox has been widely used in new energy power stations, transportation equipment in high-cold areas, cold chain automation systems, and other fields. It is particularly suitable for project scenarios that require equipment to operate stably all year round and in all weather and have extremely high environmental adaptability requirements.
When ordinary gearboxes go on strike in the cold, DongHai's Low-Temperature Gearbox can still operate efficiently, silently guarding every production capacity, and is your trustworthy "antifreeze power core". Zhejiang Donghai Reducer Co., Ltd. was established in 1991, after more than 3 decades of development. It has been a leading enterprise with scientific and technological dedication to the research and development, manufacturing, and sales of transmission equipment. The main products include a helical gearbox, a helical gear motor, and a non-standard gearbox. Explore our full range of products on our website at https://www.dhgearmotor.com/.
