XLD3-23-1.5KW
Vibration abnormality
Causes of failure: unstable installation foundation; wear of eccentric sleeve bearings; broken teeth of cycloid wheel; coupling centering error exceeds limit.
Solution: Use a level to calibrate the installation base to make the error ≤0.02mm; replace the worn bearings and perform dynamic balance tests; the broken tooth cycloid wheel needs to be replaced in the entire set.
The temperature rises too high
Cause of failure: lubricating oil Selection error; overload operation; blocked heat dissipation system.
Solution: Use N320 in summer and N220 lubricating oil in winter; install auxiliary heat sinks; clean the heat dissipation channels regularly.
Oil leak
Cause of the fault: Aging of the O-ring at the sealing surface; loose bolts of the bearing end cover; blocked ventilation holes.
Solution: Replace the seal and apply sealant; adopt a maze sealing structure; check the ventilation holes every month.
Abnormal sound
Cause of failure: wear of needle pin; abnormal meshing of cycloid wheel; bearing damage.
Solution: Use a stethoscope to locate the sound source; adjust the engagement gap to 0.15 - 0.25mm; replace severely worn parts in time.
Output shaft breaks
Cause of the fault: the axial impact load exceeds the standard; the keyway matching gap is too large; the material is improperly heat treatment.
Solution: Control the impact load within 70% of the rated value; use spline connection instead of flat keys; perform magnetic powder flaw detection regularly.
Difficulty in starting
Cause of the fault: low temperature causes the lubricating oil to solidify; foreign objects are stuck; assembly is too tight.
Solution: Idge first in winter and preheat; focus on checking the needle tooth shell grooves during disassembly and cleaning; adjust the axial clearance to 0.3 - 0.5mm.
