[0002] The pipe reamer is a kind of equipment specially used for processing pipes. It is mainly used for opening holes, chamfering, reaming, leveling slopes and other operations on pipes. The mold rotating structure of the pipe reamer controls the rotation of the mold through the gear transmission assembly to complete the processing of the pipe.

The gear transmission components are generally installed inside the housing. When the operator lubricates them, the housing needs to be disassembled, which makes the operation of lubricating the gear transmission components extremely inconvenient. At the same time, the disassembly and installation also increases the workload of the operator. Utility Model Content
