introduction：Spindle bearings for machine tools[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。]Regular maintenance of equipment、Thrust ball bearings removed during operation and replacement of peripheral parts are inspected，Need to judge in turn whether the second bearing parts can be used again and record the use of better than worse。Also carefully investigate and record the removed bearing and appearance。for

introduction：Welding as a filler metal or as a wire welding material for conducting electricity。In gas welding and tungsten gas arc welding，Welding wire is used as filler metal；In submerged arc welding、Electroslag welding and other metal gas arc welding，The welding wire is the filler metal，It is also a conductive electrode。Welding wire can be divided into3class。 ①Rolled welding wire：Most welding wires fall into this category，Carbon steel welding wire included、Low alloy structural steel welding wire、Alloy structural steel welding wire、Stainless steel welding wire and non-ferrous metal welding wire。 ②Cast welding wire：Some alloys，Such as cobalt chromium tungsten alloy，Dont

introduction：So-called clutch，As the name implies, it is to use“From the”with“us”To deliver the right amount of momentum。Clutch by friction plate，Spring blade，The pressure plate and the power output shaft are composed，It is arranged between the engine and the gearbox，To send The torque stored on the motor flywheel is transmitted to the gearbox，Ensure that the vehicle transmits the right amount of driving force and torque to the driving wheel under different driving conditions，Its in the powertrain category。In half linkage，Clutch power input The end and the power output end allow speed difference，That is, through its speed difference to achieve the transfer of the right amount of power。 The clutch is divided into three operating states，You dont depress the clutch

introduction： Stainless steel steam valve has sand holes,People often think of using argon arc welding to repair welding，However, cracks were found in the weld after welding,Not enough to fix the valve。With what to repair，How to fix The cold welding function produced by our company is very good to repair the sand hole of stainless steel steam valve,And it doesnt crack，Strong welding，Compact non-shedding。 Cold welding machine repair technology is relative to argon welding，The cold welding machine uses a large current pulse to flow instantaneously through the joint surface of the workpiece and the repair material，A technique that allows it to melt together quickly。Because it produces very little heat during welding，Base parts and materials near solder joints are kept at room temperature，the
