introduction： A systematic analysis method for uncertain decision problems。The aim is to improve the decision-making process﹐From a range of alternatives, find a suitable solution that meets certain objectives。Decision analysis has four basic elements﹕option﹑ending(Sometimes called consequences)﹑Utility and preference。 Development profile As early as1738years﹐Bernoulli has put forward the concept of utility in decision analysis。from1763Since Bayes published conditional probability, there has been the germ of statistical inference theory。1815Laplace took it to a new level。Statistical inference theory is actually decision theory in the case of risk。19

introduction：Under normal circumstances，Double row deep groove ball bearings[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]The temperature should be at30℃around，The maximum temperature shall not exceed70Degree Celsius，Or else，Will cause deformation due to high bearing temperature，In serious cases, it will cause direct damage to the jaw crusher，What is more，Directly causing the machine to explode。therefore，Always be aware of the jaw pose

introduction：Wedge joint A detachable joint that uses a wedge to unite the connected parts(See picture Wedge and wedge connection )﹐It is mainly used to transfer axial force﹐Torque transfer is also possible。Wedge connection can be divided into two kinds: loose connection and tight connection。The loose wedge has no inclination﹐Loose fit in the wedge hole﹐Only one-way axial force can be transmitted。A tight wedge with a slope on one or both sides﹐Tighten the wedge during assembly﹐There is assembly stress between the connections﹐They can squeeze together and become one﹐Therefore, it can transmit the axial force of repeated action。The tight wedge slope must ensure that the wedge can lock itself into the wedge hole。Wedge connections have gradually been replaced by threaded connections or other connections。
