Lubricating oil needs to be applied separately during elevator maintenance, and the operation of applying lubricating oil is complex. However, the elevator balance compensation chain guiding device of the present application can apply lubricating oil by itself during elevator operation. At the same time, not only can lubricating oil be applied to the rotating shafts of the guiding devices, but the sprayed lubricating oil can effectively prevent rust inside the elevator balance compensation chain guiding device and extend the service life of the elevator balance compensation chain guiding device.

This document mainly considers how to adjust the angles between the guiding wheels, but does not consider how to improve the wear resistance of the guiding device to extend the service life of the guiding device.

[0008] 4. The patent document CN103171946B discloses an elevator guide wheel assembly and its adjustment method. This document mainly considers the problem of how to improve the limiting effect of the guide wheel on the traction belt, and does not consider the problem that the disassembly and assembly of the elevator balance compensation chain guiding device are cumbersome, resulting in inconvenience in transportation, storage, and connection of the elevator balance compensation chain guiding device.
