How to check whether the CWU225-2F reducer has a box rupture 2026-02-25
CWU225-2F It is an arc cylindrical worm reducer. The box is mostly made of gray cast iron. The cracks are mostly caused by overload impact, improper installation, casting defects or long-term vibration. The inspection needs to be comprehensively judged through three dimensions: static inspection during shutdown, dynamic inspection during operation, and depth inspection of disassembly. The specific steps are as follows: 1. Comprehensive static inspection during shutdown 1. Preliminary appearance inspection: Clean the oil, dust, and rust on the surface of the box, wipe the entire machine shell with a clean rag, and focus on the vicinity of the bearing seat, the joint surface of the upper and lower machine bases, and the oil drain port/ Stress concentration areas such as around the oil filler port, the roots of the radiator, and the installation locations of anchor bolts. Visually observe whether there are obvious cracks, gaps, or missing pieces on the surface of the box. The cracks are usually accompanied by traces of rust and oil leakage. When the cracks penetrate the box, oil will continue to seep out, and there will be irregular linear rust marks at the micro-cracks. 2. Detailed inspection of key parts: Use a feeler gauge to insert into the joint surface of the upper and lower machine bases, and slide evenly along the joint surface to measure.
