The harmonic reducer is composed of three main components: rigid wheel, flexible wheel, and wave generator. Among them, the wave generator is the active part, and one of the rigid wheel and the flexible wheel is the driven part. The fixed rigid wheel is a rigid internal gear, and the flexible wheel is a thin-walled cylindrical external gear that is easily deformed. They both have a triangular (or involute) tooth shape, and the circumferences of the two are equal, but the rigid wheel is stronger than the flexible wheel. Several more teeth (usually two teeth). The wave generator consists of an elliptical disk and a flexible ball bearing, or a rotating arm with rollers at both ends. Usually the wave generator is the prime mover, one of the flexible wheel and the rigid wheel is the driven body, and the other is the fixed part.Inference of the possibility of the harmonic reducer entering impurities:1. The assembly environment of the harmonic reducer is poor;2. The burrs of the harmonic reducer's matching parts, such as impurities left over from processing are not cleaned up, and small burrs such as the joints and screw holes of the matching parts;3. Use an air gun to blow and flush the workpiece to make impurities splash to the assembly table, etc.; for this phenomenon, attention should be paid: first, use an air gun to clean the workpiece away from the assembly environment, and secondly, please do not disassemble the harmonic wave when it is not ready. reducer; 4. The oil is polluted, that is, the impurities enter the oil;5. The assembler is brought in during the assembly process. When the related parts of the harmonic reducer are cleaned, the operator should wash his hands with detergent to remove the impurities adhering to the hands or wear rubber gloves to assemble;6. Use a fan to cool down in summer.7. Thread glue or plane glue etc. enterThe above points are checked one by one, and the reason for the entry of impurities in the harmonic reducer will soon be found.
