Structural Characteristics Of Reducer - Box

The box is an important component of the reducer. It is the base of the transmission parts and should have sufficient strength and stiffness.
The box is usually made of gray cast iron, and for heavy-duty or impact loaded reducers, cast steel boxes can also be used. In order to simplify the process and reduce costs, single production reducers can use a welded steel plate box.
Grey cast iron has excellent casting performance and vibration reduction performance. In order to facilitate the installation and disassembly of shaft components, the box is made into a horizontally split type along the axis. The upper and lower box covers are connected together with bolts. The connecting bolts of the bearing seat should be as close as possible to the bearing seat hole, and the boss next to the bearing seat should have sufficient bearing surface to place the connecting bolts and ensure the wrench space required for tightening the bolts. To ensure sufficient rigidity of the box, support ribs are added near the bearing holes. To ensure the stability of the gearbox placement on the foundation and minimize the machining area of the box base plane, the box base generally does not use a complete plane.
