Why does the gearbox get stuck in low temperature environments

What is the reason for the gearbox to easily get stuck or even fail to operate in harsh low-temperature environments? Is there a solution? As an indispensable precision transmission equipment in industrial production, reducers have certain requirements for the environment, and temperature is a crucial factor. Many friends may encounter situations where the machine cannot be turned on in low temperature environments during use. In this case, as long as the equipment is moved to a room with high temperature or the gearbox is heated locally, and the equipment itself can generate heat when it is running, it can work normally.

The reasons for the gearbox sticking at low temperatures are also divided into multiple aspects. The freezing point of the gear oil we use is relatively low, and the ambient temperature will harden to a certain extent, which will make the reducer unable to operate. Secondly, the internal parts of the reducer are affected by thermal expansion under the low temperature environment. In addition, the metal materials of different parts are different, and the degree of cold contraction is also different. The friction between the fastening parts and the contact surface may increase, making the reducer easy to get stuck. It may also be affected by the metal casing of the gearbox. In extremely low temperature environments, poor quality gearbox casing can also make the gearbox components unable to operate. If forced to rotate, it can cause severe wear on the gearbox and even lead to the gearbox casing breaking.
