How to change the oil of DC geared motor? The oil change of the DC geared motor should be operated correctly according to the instructions, and the following are the oil change steps of the DC geared motor: 1. After the DC geared motor is shut down, when checking the oil level, it is necessary to cut off the power supply to prevent electric shock, then wait for the motor to cool down, and then remove the oil level plug to check whether the oil is full;   2. Install the oil level screw plug; 3. When changing the oil, due to the increase in the viscosity of the oil after cooling, it is difficult to drain the oil, so we should change the oil at the operating temperature; 4. Put an oil receiving pan under the oil drain plug, open the oil level plug, aerator and oil drain plug;   5. Remove all the oil; 6. Install the oil drain plug and inject new oil of the same brand, it should be noted that the oil quantity should be consistent with the installation position;   7. Check the oil level, tighten the oil level plug and aerator.
   Precautions for installation of worm gear motors The installation of the worm gear motor has a lot to do with the installation, connection and installation of the reaction torque bracket of the working machine.   1. The installation relationship between the worm gear motor and the working machine In order to avoid the deflection of the main shaft of the working machine and the additional force on the bearing of the worm gear reducer, the distance between the reducer and the working machine should be as small as possible under the condition that it does not affect the normal work, and its value is 5-10mm.   Second, the installation of the counter-torque bracket The counter-torque bracket should be installed on the side of the machine facing the reducer to reduce the bending moment attached to the shaft of the machine. Elastomers such as rubber are used for the bushings at the junction ends of the reaction moment bracket and fixed support to prevent deflection and absorb torque fluctuations.   3. The connection between the worm gear reducer motor and the working machine The worm gear reducer is directly encased on the main shaft of the working machine, and when the worm gear reducer is running, the reaction torque acting on the reducer box is installed on the reaction torque bracket on the worm gear reducer box or is balanced by other methods.
