How to determine the fault of XWE63-1849-1.5KW horizontal cycloid pinwheel reducer

The method of judging the failure of XWE63-1849-1.5KW horizontal cycloid pin wheel reducer is as follows:

Vibration abnormality :

• Phenomenon : The shell shakes significantly, and the equipment vibrates significantly.

• Cause : It may be that the installation foundation is unstable, such as the soft foundation or the installation surface is uneven; the eccentric sleeve bearing is worn, resulting in unstable operation; the cycloid wheel has broken teeth, affecting the transmission accuracy; the coupling centering error exceeds the limit, causing a deviation in power transmission.

• Inspection method : Use a level to check the installation base to see if its horizontal error is within the range of ≤0.02mm; for bearings and cycloid wheels, wear and breaking conditions can be checked through disassembly; use professional tools to detect the centering of the coupling.

The temperature rise is too high :

• Phenomenon : During operation of the reducer, the oil temperature exceeds 85℃.

• Cause : The lubricant Selection is incorrect, not suitable for the current working environment and load; the equipment is overloaded and is in a high load state for a long time; the heat dissipation system is blocked, such as the heat dissipation channel is blocked by dust and other debris, which affects the heat dissipation effect.

• Inspection method : Check the model and usage of lubricant to confirm whether it meets the requirements; check the workload of the equipment, compare the rated load; clean the heat dissipation channel and observe whether the heat dissipation effect is improved.

Oil leakage :

• Phenomenon : Oil leakage occurs on the sealing surface of the reducer, bearing end cover and other parts.

• Cause : The seals such as O-ring on the sealing surface are aging and damaged; the bolts on the bearing end cover are loose, resulting in a tight seal; the ventilation holes are blocked, causing internal pressure to rise and oil leakage.

• Inspection method : Carefully check the seals at the seal surface and bearing end cover to observe whether there are signs of aging, deformation or damage; check the tightness of the bolts; clean the ventilation holes to ensure they are unobstructed.

Abnormal noise :

• Phenomenon : The reducer makes abnormal sounds during operation, such as clicking sounds, metal friction sounds, periodic muffled sounds, etc.

• Cause : The clicking sound may be a wear of the needle pin; the metal friction sound may be an abnormal meshing of the cycloid wheel; the periodic muffled sound may be a bearing damage.

• Inspection method : Use tools such as stethoscopes to locate the sound source and determine the specific sounding components; check the wear of the needle pin, cycloid wheel and bearing, and measure whether the meshing gap is within a reasonable range of 0.15 - 0.25mm.
