Analysis and systematic solutions for abnormal temperature rise of dough grinding machine reducer 2026-09-02
During the operation of the noodle grinder, it is normal for the reducer housing to be slightly warm. However, if the temperature continues to rise or even becomes hot to the touch, attention must be paid to it. Generally speaking, it is within the normal range for the shell temperature to exceed the ambient temperature by 30°C. Once it exceeds 80°C, the cause needs to be investigated. If it exceeds 90°C, the machine should be shut down immediately. Otherwise, it is easy to cause serious consequences such as gear sintering and bearing damage. The root cause of the high temperature of the reducer first points to the lubrication system. Lubricating oil is the 'blood' of the internal gears and bearings of the reducer. Once something goes wrong, the temperature will quickly get out of control. If the oil level is too low, the gears and bearings are in a state of dry friction, and metal and metal collide directly to generate heat; if the oil level is too high, the resistance generated by the gears churning the oil becomes an additional heat source; and after long-term use, the lubricating oil oxidizes and deteriorates, mixed with metal debris and dust impurities, and both the lubrication and heat dissipation capabilities fail, which will also cause the body to heat up rapidly. Therefore, you should make a habit of regularly checking the oil level glass in daily use.
