Calculating method of small enclosed press crank axle pressure

The linear model in this paper has been from calculating method which used to check mechanical product. All kinds of calculations are the basic estimating methods of geometrical characteristic parameter. In practical applications, some other calculating methods are always applied to check product´s geometrical characteristics besides estimating methods. And there are many kinds of checking methods and multivariate statistics methods. In this paper, we have mainly studied calculating method about small enclosed press crank axle pressure. On the other hand, we also have studied crank moment´s calculation, stress calculation. So, we can judge the crank axle´s safety correctly.
