Installation Matters of Reducer Bearing

The bearing of the upper part of the reducer is immersed in oil or forced lubrication. In order to prevent oil leakage in the extension direction of the lower axle, the combined seal is adopted. In the current selected reducer, no forced lubrication is required, and oil immersion lubrication is adopted. This requires a filling tank on the upper part of the reducer, and the filling tank should have a high oil level. Out of the upper bearing position of the reducer to meet the needs of bearing oil-immersed lubrication.

It is worth noting that the axial and radial forces on the output shaft of the reducer are limited because the bearings on the output shaft of the reducer are installed in accordance with the conventional method. When there is a large external force, the structure of reducer should be redesigned to select bearings according to the axial and radial forces provided. However, the overhead passenger's steel rope driving wheel suffers a large torque. When directly connected with the reducer through the coupling, its external force is far greater than the radial force and axial force limited by the standard design and the reducer with reinforced bearings.

The cost of special design reducer will be greatly increased. In actual production and use, when the equipment manufacturer connects the drive wheel with the reducer, another set of bearing seat is added to bear the radial force of the steel rope drive wheel, so as to eliminate the influence of external force on the reducer.
