introduction：While the institution is operating，InstallFAGbearing[FAGbearing:The main shaft bearing is made of a solid inner ring、Outer ring、The ball、And a single row angular contact ball bearing consisting of a cage assembly with a solid window cage。]The parts are allowed to have a certain temperature，When touching the body shell with the hand，It should be normal not to feel hot，Otherwise, the temperature of the tapered roller bearing is too high。 The reasons for the high bearing temperature are：Lubricating oil quality does not meet the requirements or deterioration，Excessive lubricating oil viscosity；The mechanism assembly is too tight(Lack of clearance)；Tapered roller bearing assembly too tight；The bearing ring rotates on the shaft or in the housing；overload；FAGbearing

introduction：①Gear machining skew resulting in string shaft。Driven gear machining deviation on intermediate shaft Skew can cause string axes。Gear machining is the positioning of outer circle and end face，The gear assembly is positioned within the hole，Sometimes the inner hole is different from the outer circle，Or the inner hole is not perpendicular to the end face，It will make the machining gear and the center line of the inner hole appear skewed。This skewed herringbone gear，The plane where the center line is located is not perpendicular to the axis，When the gear rotates once，At a certain point on the center line, an axial reciprocating series will occur，Force the input shaft to reciprocate once。 In the actual transmission，Because the two halves of the driven gear deflection degree is different，right

introduction：The influence of optical fiber pressure controlled closed microwave digestion system on the determination of heavy metals in soil and plant samples was studied，The sample digestion solution was established、Microwave digestion conditions and sample pretreatment were used for digestion。The result shows that，The method is compared with that of external wet heating digestion under normal pressure，The sample digestion time is short、The amount of digestion solution is small、Sample pollution is small and so on，It is an accurate and reliable digestion method for soil and plant heavy metal detection samples。 The content of heavy metal elements in soil and plants is a necessary item in the evaluation of farmland environmental quality。In the past, the digestion of samples was usually done by atmospheric wet method plus heat treatment［1,2］，

introduction：Application and development of high speed machine tool，The spindle speed is required to increase。But machine tool spindle set parts in the manufacturing process，Inevitably due to uneven material、Shape asymmetry、Machining and assembly errors cause the center of gravity to deviate from the center of rotation，Make the machine vibrate and vibrate，Cause machine noise、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。]fever
