Why do small blender motors gear? The main reason is that the transmission power of the motor is uneven, resulting in the mismatch between the motor torque and the gear speed output force, resulting in tooth knocking. Let's talk about the content in detail.
The ground of the mixer is uneven, the mixing drum of the mixer jumps seriously, and the transmission of the motor spindle and the gear transmission are not on the same axis, so it is easy to beat teeth;
The motor or mixing drum of the small mixer is still rotating. Manually stopping the motor or drum of the small mixer is easy to beat teeth;
Before the operation of the mixer, start the motor and falsely connect the switch circuit of the motor, resulting in abnormal operation of the motor and abnormal contact between the motor and the gear, resulting in failure of the internal gear of the motor;
Due to the serious wear of the internal gear of the motor and large meshing clearance, start the small motor of the mixer to work, resulting in abnormal transmission of motor driving force and formation of teeth;
The teeth of the mixer are easy to appear only under abnormal operation. It is recommended that you use the mixer as required to avoid abnormal damage such as tooth knocking.
Therefore, to avoid such problems, it is necessary to do relevant maintenance work, such as:
The motor and reducer selected for the mixer must be consistent with those specified in the installation drawing. The mixer shall be operated by qualified personnel. If the reducer selected by the mixer is external lubrication, the lubrication system of the reducer must be started for about 15 minutes before starting the mixing equipment.
If the oil pump fails, the mixing motor must stop working, otherwise the reducer and motor will be damaged. Regularly observe and record the current value of the motor and measure the temperature of the reducer and motor. The dust cover on the motor shall be cleaned regularly to ensure good heat dissipation of the motor.
Under normal conditions, the mixing equipment operates stably; The motor current is stable, and the current value is generally about 80% of the rated current value; The reducer and motor shall be free of noise, and the temperature rise of the reducer shall not exceed 60 ℃.
When stopping the mixer, first stop the main motor and then stop the lubrication system. The bearing housing shall be lubricated regularly, and the rolling bearing must be replaced for a fixed service life. The reducer and motor can be operated and maintained with reference to their instructions.
We have found the reason for the gear beating of the small mixer motor. The solution is to make a plan according to the actual situation. Of course, it is recommended to go to a professional maintenance factory for repair. For more information, please follow the website www.zishangliaojiaobanji.com Cn!
