The upper bearing of the reducer is immersed in oil or forced lubrication. In order to prevent oil leakage in the lower shaft extension direction, the seal adopts a combined seal. In the currently selected reducer, no forced lubrication is required. Oil-immersed lubrication is used. This requires a replenishment tank on the top of the reducer, and the oil level of the replenishment tank should be higher than the upper bearing position of the reducer, in order to meet the needs of the bearing oil lubrication.

It is worth noting that the axial and radial forces on the output shaft of the reducer are limited. Because the bearings of the output shaft of the reducer are installed in accordance with conventional methods, there is a certain limit on receiving external forces. When there is a large external force, it is necessary to redesign the structure of the reducer to select the bearing according to the axial and radial forces provided.
However, the steel rope driving wheel of the aerial passenger is subjected to a large torque. If it is directly connected to the reducer through a coupling, the external force is far greater than the radial and axial forces defined by the standard design and reinforced bearing reducer.
With the specially designed reducer, its cost will increase significantly. In actual production and use, when the equipment manufacturer connects the drive wheel with the reducer, another set of bearing seats is added to bear the radial force of the steel wire drive wheel to eliminate the impact of the external force on the reducer.
