The bearing on the upper part of the reducer adopts oil immersion or forced lubrication. In order to prevent oil leakage in the direction of the lower shaft extension of the speed reducer, the sealing method adopts a combined seal. In the current selected reducer, no forced lubrication is required, and oil immersion lubrication is used. , which requires a supplementary oil tank on the upper part of the reducer, and the oil level of the supplementary tank should be higher than the position of the upper bearing of the reducer to meet the needs of bearing oil lubrication.
It is worth noting that the output shaft of the reducer bears the axial force and radial force. Since the bearings of the output shaft of the reducer are installed in accordance with the routine, there are certain restrictions on receiving external forces.When there is a large external force, it is necessary to redesign the structure of the reducer and select the bearing according to the provided axial force and radial force.
However, the steel rope driving wheel of the aerial man-ride vehicle is subjected to a large torque. If it is directly connected to the reducer through a coupling, the external force is much greater than the radial force and axial force limited by the standard design and the reducer with reinforced bearings.
And the use of special design reducer, its cost will increase significantly.In actual production and use, when the equipment manufacturer connects the drive wheel with the reducer, an additional sleeve bearing seat is added to bear the radial force of the steel cable drive wheel, so as to eliminate the influence of external force on the reducer.
