introduction：When welding with a laser beam as a heat source,The laser will emit high power density(10(～10(watts／centimetre()The laser beam is condensed into a focused beam,Used to bombard the surface of the workpiece，Generate heat energy，Melting work(See picture[Laser welding diagram])A laser beam is a coherent beam with a single frequency，There is no divergence in emission，A lens can be used to converge to a focal point of a certain size（Diameter is... 0.076～0.8millimeter）A small focus laser beam can be used for welding、Cut and punch；Large focus laser beam can be used for heat treatment of material surface。The direction of the laser beam can be arbitrarily changed by the reflector，So it can weld generally

introduction：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 full name of the steel is rolling bearing steel，It has high compressive strength and fatigue limit，High hardness，High wear resistance and toughness，Good hardenability，Extremely strict control of sulfur and phosphorus，Its a high-grade, high-quality steel，Can do cold do touch steel。Specific gravity：7.81 (one)Bearing steel forging temperature (1)

introduction：The choice of gasket material is not an easy task。The variables that arise in the flange connection are seemingly endless。All these uncertainties，Will affect the sealing effect of the gasket。formerly“TAMP”These parameters seem to be sufficient，But today，The processing quality of the flange、Embedment amount of bolt thread teeth、Flange rotation、Bolt tension、Medium filler and surface treatment of flanges（There are many other factors）All affect the sealing effect of the gasket。The bearing capacity of gasket decreases with the increase of material thickness，The thinner the material，The more pressure it carries。In addition，Proper bolt loading sequence can ensure balanced load

introduction：Disc brake A brake that relies on friction between disks to stop﹐There are two main types: full plate type and point plate type(See picture Type of disc brake )。Full disc brake﹕It consists of a fixed disk and a moving disk。The setting disc is connected by a guiding flat key or spline(See key connection﹑Spline joint)In the fixed housing﹐The moving disc is mounted on the brake shaft with a guiding flat key or spline﹐And rotate with the axis。When subjected to axial forces﹐dynamic﹑The set discs press against each other and brake。The brake is compact in construction﹐Large friction area﹐High braking torque﹐But the heat dissipation condition is poor。To increase braking torque or reduce radial size﹐The number of plates can be increased

introduction：1.The measurement area is specified towardsKOYObearing[KOYObearing:kOYOBearings are generally required to bear large loads，Often without a cage，Instead, fill the inner and outer raceways with rolling elements。And most small and medium-sizedKOYORolling bearings are equipped with retainers。 inKOYOBearing in the processing process，The outer ring of the bearing、Inner ring、How do the roller and cage fit together。]Measurement of inside or outside diameter，In China, it is stipulated that the measurement should be made in the area with a maximum chamfer coordinate on each side leaving the southern side of the ring，In foreign countries, it is usually stipulated that the two ends of the ring are twice the chamfered coordinates in the area
