Micro reduction motors generate certain noise during the operation of micro reduction motors due to their use in various products with high torque and low speed. Excessive noise can affect the product experience. How to reduce the noise of micro reduction motor gear reducer? Share the correct selection of motor lubricating grease to reduce gearbox noise.

The lubrication of reducers also has its own conditions, and the lubrication conditions of different reducers are also different. When selecting lubricating grease for transmission gearboxes, consideration should be given to the transmission characteristics, load properties, size, and operating speed of the gearbox. Heavy duty gear transmission can choose lubricating grease with high viscosity and good lubricity; Worm gear transmission is not conducive to the formation of oil film, and lubricating grease containing both extreme pressure additives and oil additives can be selected; For transmission components with light load, high speed, and intermittent operation, use lubricating grease with lower viscosity. Split type gear transmission should use lubricating grease that is corrosion-resistant, anti-oxidation, has good anti-wear performance, and strong adhesion.

Let's first understand the reasons for the noise generated by micro reduction motors and the impact of inappropriate lubricating grease on reduction motors.

In gear reducer combinations with high output and input speeds, long-term high-speed operation can lead to increased friction and greater heat generation. If the decelerator runs at high speed for a long time without replacing the lubricating grease, the existing lubricating grease inside will become very viscous and may attach foreign objects. In this case, it will ultimately lead to two outcomes. One is abnormal motor noise, and the other is temperature rise.

If the lubricating grease thickens or foreign objects adhere, the wear between the gears of the reducer will accelerate, and the gears of the reducer may wear out and the teeth may fall off. As the number of foreign objects increases, the impact on the gears will also increase; This is also a phenomenon where abnormal noise occurs, causing uneven abnormal noise.

In addition, due to increased friction, the temperature rises. When there is only one ventilation hole, the heat generated by internal friction cannot be immediately dissipated, resulting in an increase in temperature. At this point, we can replace the appropriate motor grease. The new lubricating grease can reduce friction while also preventing more heating phenomena from occurring.
