Key customized design of non-standard reducers for enhancing low-temperature adaptability

Compared to standard reducers, non-standard reducers can enhance low-temperature adaptability through targeted design, optimizing operational performance from the source:

Material customization: The shell is made of "low-temperature toughness materials" (such as Q345D low-alloy high-strength steel, with an impact toughness of -40 ℃ ≥ 34J, which is better than the 18J of ordinary Q235 steel) to avoid cracking of the shell at low temperatures; The gear adopts the process of "carburizing and quenching+low-temperature tempering" (tempering temperature of 180-200 ℃, and very high temperature of 200-250 ℃) to improve the low-temperature hardness and toughness of the tooth surface.

Structural optimization: The lubricating oil chamber is designed as a "downward type" (standard reducers are mostly side mounted), allowing the lubricating oil to naturally flow towards the gears and bearings under the action of gravity, reducing the flow resistance caused by high viscosity at low temperatures; At the same time, a "oil discharge heating tube" is installed at the bottom of the oil chamber to facilitate heating and oil discharge after shutdown, avoiding oil solidification that cannot be discharged.

Customization of lubrication system: Integrated with a "small circulating oil pump" (standard reducers often use splash lubrication), it forcibly delivers lubricating oil to key parts (such as high-speed shaft bearings) to ensure stable oil film at low temperatures; Simultaneously equipped with an "oil viscosity sensor" to monitor viscosity changes in real time. When the viscosity exceeds a threshold (such as 40 ℃ kinematic viscosity>100mm ²/s), the heating device will automatically start.
