introduction： The function of the coupling is to connect the pump shaft with the pump motor shaft to rotate together。Coupling is also called coupling、Counter wheel、Backrest wheel, etc。Common couplings are rigid couplings、Elastic coupling、Toothed coupling、Hydraulic coupling, etc。 Working principle and application of coupling 1、Coupling function Used to join the two axes together，The two axes cannot be separated when the machine is running，Only after the machine stops and disconnects，The two axes can be separated。 2、Type of coupling The two shafts to which a coupling is attached，Due to manufacturing and installation errors，The deformation after loading and the influence of temperature change，It causes two axes

introduction：Bearing material The bearing shell is divided into split type and integral structure。In order to improve the friction properties of the bearing surface，One or two layers of antifriction material are often cast on its inner diameter，Commonly called 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 liner，Therefore, there are bimetal bearing bushing and three metal bearing bushing。 unitary

introduction：１、Control friction：Add lubricant between rubbing surfaces，lubricate，Reduce direct metal contact between friction surfaces，Thereby reducing the coefficient of friction，Reduce friction and reduce power consumption。 ２、Reduce wear：There is a lubrication film with a certain strength between the friction surfaces，Capable of supporting load，Avoid or reduce direct contact with metal surfaces，Thus, the plastic deformation of the contact surface can be reduced、Fusion welding、Various degrees of adhesive wear such as cutting and bonding。 ３、cooling：Lubricants reduce the coefficient of friction，Reduce friction heat generation。 ４、Sealed isolation：A lubricant, especially a grease, covering the friction surface or

introduction：1.The slewing bearing is not flexible in rotation。 The slewing bearing has been strictly inspected and tested before leaving the factory，All are qualified products，Therefore, if the retention phenomenon is found, it can be ruled out in the following ways。 (1)The newly purchased product idling is not flexible。Please check the production date of the slewing bearing，If the time is longer(Such as more than half a year)、Cooler climate，It is possible that the viscosity of the grease in the raceway is large, resulting in poor operation(Cold region、More prominent in winter)。Elimination method： •It can be used normally if it can run and there is no other abnormality after the force is applied；If accompanied by abnormal sound，Check for serious trauma during transportation，And will
