How to improve the shaft seal of the reducer

As an independent component, the reducer is often used in the reduction transmission device between the original moving part and the working machine. The shaft seal of the reducer accounts for a small proportion of the equipment, but it is related to the normal operation of the equipment. In order to reduce the equipment The reducer manufacturer will simplify the installation steps and change its bearings.

　　 1. The shaft seal of the reducer whose output shaft is half shaft is improved. There is no coupling on the output shaft of the China Brake Gear Motors of the entire shaft transmission, and the workload is too large and unrealistic. When the reducer is overhauled, apply D05 silicone rubber sealant on the joint surface and end cover to replace the earlier products. When installing the oil seal, first remove the spring, saw the oil seal and open it, and put the oil seal on the shaft from the opening. Butt the opening with the adhesive, with the opening facing upward, then install the spring and push in the end cap. Generally, there will be no leakage. If the static sealing point of the reducer leaks oil during operation, the oil surface emergency repair agent of surface engineering technology can be used to stick it to eliminate the oil leakage.

　　 2. The shaft seal of the reducer whose output shaft is a whole shaft is improved. The output shaft of the reducer of most equipment such as belt conveyors, screw unloaders, and impeller coal feeders is a half shaft, which is convenient for modification. Disassemble the reducer, remove the coupling, take out the shaft seal end cover of the reducer, machine the groove on the outer side of the original end cover according to the size of the supporting frame oil seal, install the frame oil seal, and the side with the spring is inward.

When making changes to the reducer, it can be carried out according to the above-mentioned method of half-shaft and full-shaft, which can effectively save time and provide convenience. When the static seal of the reducer leaks, new sealing materials can be used for sticking and blocking, thereby promoting Changes to the shaft seal.
