introduction: Electromagnetic clutch is a kind of coil on and off to control the clutch engagement and separation。Because of the use of electromagnetic clutch, we may need to adjust and control the electromagnetic clutch at any time,So theres a lot of problems with that because a little bit of careless adjustment can cause damage。Electromagnetic clutch、The friction disc of the brake is worn after long-term use,Cause the gap between the electromagnet and the armature to increase,Elongate the compression spring length,Reduced elasticity,Cause to slip。At this time, the gap increases,Not only the suction voltage of the armature coil rises,And the armature cant snap,Easy to burn other electrical components。So when adjusting,Need to understand

introduction: The vibration detection period is set too long,May not catchINAbearing[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。]Information begins to deteriorate,The period is too short. Procedure,It also increases the number of workers and the cost of testing。Therefore, it should be based on the structural characteristics of the bearing、Transmission mode、Rotational speed、Factors such as power and failure mode,Reasonable selection of vibration detection

introduction:Fretting wear A composite type of wear caused by small amplitude vibration between compressed metal surfaces。In vibrating machinery﹐Threaded joint﹑Spline joints and interference fit joints are prone to fretting wear。It is generally believed that﹐The mechanism of fretting wear is﹕The normal pressure between the friction surfaces causes the micro-convex surfaces to stick。The bonding points are clipped by small amplitude vibration to become abrasive chips﹐The debris is then oxidized。The oxidized abrasive particles act as abrasive particles in the wear process﹐Pitting or worm-like scars on a rubbing surface。These marks or scars are the source of stress concentration﹐Therefore, it is also the source of the failure of parts under dynamic load。
