Shg-45-100-2sh, a flexible wheel with external teeth that can produce radial elastic deformation when working, and a wave generator with oval shape and flexible rolling bearing on the outer ring installed in the internal transmission part of the flexible wheel. The number of external teeth of flexible wheel is less than the number of internal teeth of rigid wheel. When the wave generator rotates, the outer teeth of the flexible wheel corresponding to the long axis direction just completely engage the inner teeth of the rigid wheel
The purpose of cleaning is to reduce porosity, oxidation and slag inclusion defects, and ensure the bonding strength of the surfacing layer to improve the quality of welding repair, so it is necessary to clean the oil, rust and oxide on the surface of the gear before welding. The method of the harmonic actuator SHG-45-100-2SH is: first, clean it with gasoline or 10% sodium nitrous oxide aqueous solution at 70-80℃, and then wash it with water; Also can use wire brush, scraper, emery cloth or grinding wheel to thoroughly polish the burr, rust, pitting and peeling pit of the part of the fu, so that it reveals a new metallic luster.
The original standard gear, can adopt high displacement meshing, repair big wheel, match small wheel. However, at this time, the center distance of the gear pair is unchanged, and the meshing Angle does not increase, and the Harmonic actuator SHG-45-100-2SH has no benefit to improve the contact strength. Of course, when repairing large gears, negative displacement must be used.
Splicing method is used to repair the gear when the large tooth ring is broken, or when the larger gear has some teeth damaged, splicing method can be used to repair. Special attention should be paid to the following aspects in the process of splicing gear repair.
The damaged parts of the gear should be cut by gas welding or saw (or toothless saw), and then the deformed gear must be restored to its original shape with a tool. After the internal cracks of gear material are located and fixed by the ShG-45-100-2SH nondestructive inspection, the residual life of the gear material is evaluated by fracture mechanics, and then it is properly disposed. Limit (control working conditions, such as load) use, or scrap replacement.
In addition to the conventional gear static strength, fatigue strength, tooth surface bonding and wear tests, the gear carrying capacity test also includes the testing of some influencing parameters, such as gear dynamic load Hamenako shift open harmonic actuator SHG-45-100-2SH, gear tooth load distribution, tooth surface and body temperature tests, etc.
