introduction： Automobile hub 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 main role is to bear the weight of the car and provide accurate guidance for the transmission of the wheel hub。Hub bearings bear both radial and axial loads，Is a very important security piece。Now most of the domestic cars still use the traditional two sets of separate tapered roller bearings or Angle joints

introduction：zhankaitu Developed view developing drawing A figure obtained when the surface of a spatial form is flattened on a plane，It is a content of the study of descriptive geometry。For parts made of sheet material，In addition to the need to use a multifaceted orthographic diagram to represent the shape of the part，Also use the development diagram to show the shape of the sheet before the part is made。Draw the expansion drawing according to the multifaceted orthographic drawing of the parts，Its essentially finding the true shape of the surface。The surfaces that make up the form can be divided into two categories：plane、Surfaces that can be flattened, such as cylinders and cones, are developable surfaces；A table that cannot be flattened, such as a sphere or a torus
