How to determine if the operating sound of K47D90S4/1.1KW/40/M1/90 reducer is normal

judge K47D90S4/1.1KW/40/M1/90 Whether the sound of the gearbox running is normal can be approached from the following aspects:

Understand the normal sound characteristics: During normal operation of the gearbox, its sound is usually smooth, uniform, and low pitched. This is because the gears, bearings, and other components inside the reducer mesh and rotate smoothly during normal operation, without significant impact or abnormal friction, producing a continuous and stable operating sound.

Comparing sounds under different operating conditions: The sound of the gearbox may vary under different load and speed conditions, but it should still remain stable. For example, during no-load start-up, the sound generated by the motor driving the gearbox is mainly the running sound of the motor and the slight friction sound of the internal components of the gearbox starting to rotate, which is relatively light and smooth; As the load gradually increases, the sound of the gearbox will gradually increase, but as long as all components are normal, the sound will still be uniform and there will be no sudden changes or abnormal high-frequency noise.

Using auditory tools to assist in judgment: Professional auditory tools such as stethoscopes or industrial vibration and noise testers can be used to assist in judgment. Place the probe of the stethoscope on the casing of the gearbox, close to key parts such as the gearbox, bearing seat, etc., and listen carefully to the internal sounds. By using a stethoscope, the details of the sound can be more clearly distinguished, which helps to detect some subtle abnormal sounds. Industrial vibration and noise testers can more accurately measure parameters such as frequency and amplitude of sound, and determine whether the sound is abnormal by comparing it with data during normal operation.

Identifying the type of abnormal sound: Abnormal sound is often an important basis for judging the operating status of the gearbox. For example, piercing screams may be caused by poor gear meshing, worn tooth surfaces, or insufficient lubrication; Periodic impact sounds may be caused by broken teeth on gears, loose key connections, or damaged bearings; The dull friction sound may be due to abnormal contact or friction between internal components, such as wear between shafts and bearings, friction between seals and shafts, etc.

Through the comprehensive application of the above methods, a more accurate judgment can be made

Check if the operating sound of the gearbox is normal, promptly identify potential problems, and take corresponding measures for repair and maintenance.
