Which of the common faults of BLY39-17-22KW cycloidal pinwheel reducer is the most difficult to solve?

The most difficult fault to solve for the BLY39-17-22KW cycloidal pinwheel reducer is the wear of the bearing chamber (including the wear of the box bearing hole and the bearing seat mating surface), followed by the severe wear/broken teeth of the cycloidal wheel and pin gear shell set.

1. Why are these two types of faults the most difficult to repair?

1. The repair cost is high : the bearing chamber wear requires repair welding and then machining or inserting, which requires high precision (within a few wires), long downtime, and expensive costs; the cycloidal wheel and pin gear shell need to be replaced in sets, and the single-piece purchase cycle is long.

2. Accuracy is difficult to guarantee : the coaxiality and fit tolerance of the bearing hole directly affect the operating stability, welding repair is easy to deform, and ordinary repair is difficult to achieve the original accuracy.

3. Risk of chain damage : Bearing damage can easily cause journal wear, further expanding the gap in the bearing chamber, forming a vicious cycle.

4. Difficulty in disassembly and assembly : It involves precision components such as eccentric bearings and couplings, which require special tools. Improper disassembly and assembly can easily damage parts.

2. Quick identification and response

Summary : Bearing chamber wear and serious damage to core transmission parts have become the most difficult faults of BLY39-17-22KW due to high precision requirements, high costs, and long repair cycles. Daily lubrication and alignment can greatly reduce the probability of such failures.
