Disassembly and installation of planetary reducers
Thread Content
There are certain techniques involved in disassembling and assembling planetary reducers, and you surely know them; please share your experience so that others can learn from it*
During assembly, the mark on the cycloid wheel should face upward; depending on the manufacturer, there are specific requirements regarding whether the marks align or are 180 degrees apart.
All the cycloidal wheel assembly markings I’ve seen are 180 degrees apart.
The two cycloidal gears of a cycloidal pinwheel planetary reducer are usually marked at the time of manufacture; careful observation is sufficient when disassembling it.
A few days ago, I disassembled a BLD-type reducer. The two cycloidal gears are produced in pairs, with steel stamp marks applied to them; the gear I disassembled had the marks “23 57” on it. When these two cycloidal gears are assembled, the marks face upward and they are placed at an angle of 180 degrees to each other. The assembly of other components such as shafts and bearings, bearings and pinion housings, as well as the large end cover, is carried out by heating and pressing them in.
