introduction： The use of electromagnetic brakes 1、Check for wear and dirt；Check the mechanical wear of moving parts regularly，And remove the dust on the surface of the electromagnet parts、Flower hair and dirt。 2、oiling；Lubricant is often added to the moving part of the electromagnetic brake。 3、Check armature stroke length；Check the length of armature stroke regularly。Because during the operation of the brake，Due to abrasion of the split surface，The travel length of the armature will increase。When the armature stroke length does not reach the normal value，Adjustments must be made

introduction：Computer cooling fan，Fan 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。]The reliability of the system determines the service life of the cooling fan and its noise and stability。Classified according to fan bearings，There are generally two types of air-cooled radiators：Oil bearing fans and ball bearing fans。Oil bearing is cheap though，But the oil bearing is sliding friction

introduction：According to the law of supply and demand to determine the economic and reasonable material storage in the process of production and circulation management work inventory management should play a buffer role,Make the logistics balanced and smooth，Both to ensure normal production and supply，And can reasonably compress the stock of funds，In order to get better economic results。 1915years，ColumbianF.W.Harris published models of economic order sizes，Pioneered the study of modern inventory theory。Before this，ItalianV.Pareto proposed Paretos law when he studied the distribution of wealth in the world,For inventory managementABCClassification method。With the scientific management work，Inventory management

introduction：1、carbon（C）：The carbon content in steel increases，Yield point and tensile strength increase，But plasticity and impact are reduced，Equivalent carbon0.23％overtime，The weldability of the steel deteriorates，Therefore, low alloy structural steel for welding，Carbon content generally does not exceed0.20％。High carbon content will also reduce the resistance of steel to atmospheric corrosion，High carbon steel is susceptible to corrosion in an open yard；In addition，Carbon can increase the cold brittleness and aging sensitivity of steel。 2、silicon（Si）：Silicon is added as a reducing agent and deoxidation in the steelmaking process

introduction：FAGbearing[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 noise inside the hard disk is mainly from the movement of different motor components，And from this can be the form of rotating wind noise，subdivision，Magnetic failure of the motor、Bearing column、Bearings and discs are the source of noise，So that there is no big difference for ball bearings。 Despite the lubricant，And the inner wall of the ball and bearing is also smooth．But they are always in contact，High speed operation makes the ball shaft

introduction：Temporary protection Material protection technology to prevent the bare surface of metal parts from rust during the process or during storage and transportation﹐Also known as rust prevention。Mechanical products are generally in a packaging state during storage and transportation﹐Therefore, it is also called packaging rust prevention or storage rust prevention。When choosing temporary protection measures, consider the type of material to be protected。Steel rusts under the action of water and oxygen in the general atmosphere﹐It is more serious in the industrial and Marine atmosphere。copper﹑aluminum﹑zinc﹑Magnesium, etc., also changes color in some environments﹑tarnishing﹑corrode。therefore﹐Metal parts must be protected between production processes and during storage and transportation﹐To maintain its appearance﹑Accuracy and performance。
