The harmonic reducer includes a base with a cavity inside for the flexible wheel to be placed, characterized in that the flexible wheel includes a cylindrical part with teeth and a ring-shaped support part outside the cylindrical part, the outer side of the support part has a ring-shaped fixing part, the fixing part has a threaded hole, and the harmonic reducer also includes a bolt I, The bolt passes through the base from the outside of the base and is fixed on the threaded hole of the fixing part along the flexible shaft direction.
Three precautions for harmonic reducer operation:
1. When installing the harmonic reducer, attention shall be paid to the alignment of the transmission center axis, and the error shall not be greater than the use compensation of the coupling used. Good alignment can prolong service life and obtain ideal transmission efficiency.
2. When installing the transmission parts on the output shaft, it is not allowed to knock with a hammer. Generally, the assembly fixture and the internal thread of the shaft end are used to press the transmission parts with bolts. Otherwise, the internal parts of the harmonic reducer may be damaged. Rigid fixed couplings are not used. Improper installation of such couplings will cause unnecessary external loads, resulting in early damage of bearings and even fracture of output shaft in serious cases.
3. The installation device shall be installed according to the regulations to ensure that the staff can easily approach the oil mark, vent plug and oil drain plug. After the installation is in place, the accuracy of the installation position shall be comprehensively checked in order, and the reliability of the tightening of each fastener shall be able to rotate flexibly after installation. The harmonic reducer adopts oil pool splash lubrication. Before operation, the user needs to remove the plug of the vent hole and replace the vent plug. According to different installation positions, open the oil level plug screw to check the height of the oil level line, add oil from the oil level plug until the lubricating oil overflows from the screw hole of the oil level plug, screw on the oil level plug and confirm that there is no error, and then carry out no-load test run. The time shall not be less than 2 hours. The operation shall be stable without impact, vibration, noise and oil leakage. Any abnormality shall be eliminated in time. After a certain period of time, the oil level should be checked again to prevent possible leakage of the casing. If the ambient temperature is too high or too low, the brand of the lubricating oil can be changed.
The above is all about the status of these three aspects that should be paid attention to during the work of the harmonic reducer. I hope it will be helpful for you to use this equipment in the future.
