ALIGNMENT OF THE MAJOR HOUSINGS IN A WANKEL ROTARY ENGINE

摘要

A method, readily adapted to automation, for assembly of a rotary internal combustion engine is disclosed. Independent and self-contained housing units are prepared which eliminate the need for high compression and superior sealing between said housing units, each unit is free to move in a plane perpendicular to the eccentric shaft, and dowels between the units or certain subassemblies have been eliminated. An oil soluble adhesive is used to facilitate unitary handling and installation of apex seal assemblies and a unique apron or separator means is used to install a split center bearing which serves as a unique element of the engine assembly. During the final step of the method, high pressure air is injected into the oil gallery or oil lubrication passage system of the engine, while vibration is applied to the housing units, resulting in a perfectly mated and aligned engine; unique tie-bolts extending the length of the engine, are torqued to full level with the engine in such accurately aligned condition.
