introduction： Influence rolling bearing[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。]There can be many factors in service life，Use factors and intrinsic factors can be further explained。 The use factor mainly refers to the installation adjustment、Service and maintenance、Whether the maintenance and repair meet the technical requirements。Install according to rolling bearings、Use、maintenance

introduction：The molten steel from the furnace is cast into billets，The ingot or billet is pressed into steel（Iron and steel products）。Many kinds of steel，Generally can be divided into types、plate、Four categories of tubes and wires。 1、Section steels There are many types of steel，It is a kind of solid long steel with a certain cross-section shape and size。According to its different section shape and divided into simple and complex section two。The former includes round steel、Square steel、Flat steel、Hexagon and Angle steel；The latter includes steel rails、joist、Steel channel、Window frame steel and shaped steel, etc。Have a diameter of6.5-9.0mmSmall round steel called wire。 2、Steel plates

introduction：Used for planing、A tool having a cutting part（See picture[Plane tool structure diagram]）。Planer knife can be divided into longitudinal cutting according to the use、transversal、fluting、Cutting and forming planer knives, etc。The structure of the planer is basically similar to that of the turning tool，But the planer knife is working intermittently，Impact load。therefore，Under the same cutting section,The section size of the tool bar is larger than that of the turning tool1.25～1.5times，And adopt large negative edge Angle(-10°～-20°)，To improve the performance of cutting edge against impact load。In order to avoid bending deformation of the planer bar under the action of cutting force，This allows the blade to nibble into the workpiece，Usually a bend is used

introduction：After decomposing the engine，Check the skew of the crankshaft。UseVRing supports the crankshaft，Use a dial gauge to read the degree of yaw，The degree of deflection of the crankshaft shall not exceed the limit of use，Limit of use0.05mm。 Excessive crankshaft yaw is often the cause of abnormal engine vibration，This vibration will shorten the life of the engine。therefore，If the limit of use is exceeded, it should be sent to the repair department for repair or replacement。 Check bearing[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 are produced on the shaft
