How to deal with the BWD8-29-30-6P cycloidal reducer that fails the load acceptance

Immediately deactivate and investigate the source of the fault. When the BWD8-29-30-6P cycloid reducer fails the load acceptance, it usually indicates that its output torque, temperature rise or operating stability does not meet the standards. The reasons need to be systematically investigated and corresponding measures taken.

1. Prioritize troubleshooting of installation and working conditions problems (accounting for more than 60% of heating/overload problems)

1. Check the coaxiality and connection status of the shaft
system. Reducers in electronic equipment have extremely high installation accuracy requirements. If there is a coaxiality deviation between the input/output shaft, the motor, and the load end, it will cause uneven stress on the internal transmission components, increase friction, and cause overheating or weak output.

(1) Use a dial indicator to detect the runout at both ends of the coupling and control it within 0.05mm.

(2) Tighten all connecting bolts to ensure there is no looseness

2. Confirm whether the actual load exceeds the limit.
The rated output torque of BWD8-29-30-6P is approximately 300N·m. If the actual load exceeds 1.2 times this value (ie 360N·m), long-term operation will cause shutdown or component damage.

(1) Reverse the load condition through current monitoring to avoid overload operation

(2) If the load is indeed too large, it should be replaced with a larger speed ratio or machine model.

‌3. Improve heat dissipation conditions‌If
the reducer is installed in a closed space or the surrounding components are densely packed, the heat will be difficult to dissipate, which will cause the temperature rise to exceed the standard (>80℃).

(1) Check whether the vents are blocked and clean the dust and oil

(2) Add external heat sink or forced air cooling device

2. Check the internal status and lubrication system

‌1. Check the status of lubricating oil‌

(1) The oil level should be between the "upper and lower limits" of the oil mark. If it is too high, it will increase the oil churning loss, and if it is too low, there will be insufficient lubrication.

(2) Use the recommended model: ‌46# extreme pressure industrial gear oil‌. If the oil emulsifies or turns black, replace it immediately

‌2. Check for damage to internal transmission components‌If
the above external factors have been eliminated and the load still cannot be loaded normally, there may be internal quality problems:

(1) ‌Poor meshing between the cycloidal wheel and the pin teeth‌: disassemble and check whether there is any foreign matter stuck or assembly deviation

‌(2) Bearing damage or cage fracture‌: abnormal noise or vibration during operation

( 3) Keyway wear or flat key breakage‌: leading to interruption of power transmission and slippage of the output shaft
