1 , , I Abstract The Crankshaft seat is used to support the Crankshaft outer ring, inner ring for fixing the Crankshaft outer ring rotation, let alone, keep still, always keep consistent with the direction of transmission (such as motor rotation direction), and keep the balance; and aggregate concept is Crankshaft and the Crankshaft seat, in order to facilitate the application, so that the benefits of cooperation can be better, more convenient to use, to reduce the use of cost for manufacturers. As for the shape, variety, is usually a box can be installed in the Crankshaft. With the continuous progress of science and technology, it plays a more and more important role in the national economy, the development prospect is very wide, especially in the automotive and electronic appliances such as the rapid development of the field. The course design is the subject of the Crankshaft seat design, is a teaching link in the completion of the manufacturing technology of automobile; under the guidance of the teacher, to a full course of primary learn the integrated use of previously learned in the design, the basic training and independence completion of an engineering. Keywords: Crankshaft process specifications for design of
