Medium-speed engine output end housing

The utility model belongs to the technical field of engines, and particularly relates to a medium-speed engine output end housing which comprises an upper housing body and a lower housing body connected with the upper housing body, the upper housing body and the lower housing body are detachably and fixedly connected, a containing cavity capable of containing a crankshaft is formed when the upper housing body and the lower housing body are connected, and a sealing structure is arranged on the inner wall of the containing cavity. The intermediate-speed engine output end housing is provided with the sealing ring, the sealing ring does not need to be permanently fixed to the crankshaft, and on the basis that disassembly is convenient, the problem that components cannot be independently replaced due to the fact that the sealing ring and the crankshaft are permanently assembled is solved through the intermediate-speed engine output end housing in split design. 本实用新型属于发动机技术领域，特别涉及一种中速机输出端罩壳，包括上壳体和与上壳体连接的下壳体，上壳体和下壳体
