The surface of the reducer is easily damaged, if there is surface damage, how should we deal with it, the following for the reducer surface damage should be dealt with a brief understanding: 1. Once the bearing is severely worn, overloaded or impacted and the reducer bearing is slightly deformed or bent, it will cause the rotor to sweep. As a result of sweeping, the surface of the iron core is scratched, and the heavy core is worn and the winding is burned by touching the shell, and the power supply should be cut off immediately, so that the gearmotor stops working and inspects. 2. The silicon steel sheet at the core abrasion part is annealed due to friction overheating, resulting in a decrease in the magnetic permeability of the silicon steel sheet, if not treated in time, with the aging of the core insulation of the planetary gear reducer, the eddy current continues to increase, resulting in an increase in the temperature rise of the planetary gear reducer, and the micro motor overheats or even burns out. 3. The winding insulation breakdown short circuit or the winding short circuit to the ground produces an arc, so that the surface of the core is burned, and the surface of the burned core is often uneven. This not only affects the normal operation of the reducer, but also leads to a short circuit between silicon steel sheets, which increases the core vortex. After understanding how to deal with the surface damage of the reducer, I hope that it will be more helpful to us in the future, and at the same time will bring greater benefits, which is also more conducive to our use.


Reducers are widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical industry, textile, printing and dyeing hard tooth surface reducer, pharmaceutical and other fields. Hard tooth surface reducer is a power transmission mechanism that uses the speed converter of the gear to decelerate the number of rotations of the motor to the required number of rotations and obtain a larger torque. Four major skills for the use of the reducer: First, during the work, when the oil temperature rises more than 80 °C or the oil pool temperature exceeds 100 °C and produces abnormal noise, it should be stopped, check the cause, eliminate the fault, and replace the lubricating oil before continuing to operate Second, when changing the oil, wait for the reducer to cool down without the risk of combustion, but it should still be kept warm, because after complete cooling, the viscosity of the oil increases and it is difficult to drain oil. Note: Cut off the power to the transmission to prevent unintentional power. Third, after 200~300 hours of operation, the yi oil change should be carried out, and the quality of the oil should be checked regularly in the future use, and the oil mixed with impurities or deterioration must be replaced in time. Under normal circumstances, for the reducer that works continuously for a long time, replace the new oil according to 5000 hours of operation or once a year, and the reducer that has been out of service for a long time should also be replaced with new oil before re-operation. The reducer should be added with the same oil as the original brand, and should not be mixed with different brands of oil, and oils of the same brand but different viscosity are allowed to be mixed. 4. The user should have reasonable use and maintenance rules and regulations, and the operation of the reducer and the problems found in the inspection should be carefully recorded, and the above provisions should be strictly implemented.
