introduction： If the lubrication interval is less than six months，It is better to use the method of grease supply，This method is relatively simple，Does not interrupt the operation of the equipment。Compared with continuously lubricated hair that is，More can maintain a firm temperature and at a lower level。 When the interval of supplementary lubrication is good for six months，It is generally recommended to use the method of updating the grease。Updating grease is usually also regularly maintainedTIMKENbearing[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 the other parts are

introduction：Linear bearing[Linear bearing:Metal linear bearing is a linear motion system produced at a low cost，For use with infinite stroke and cylindrical shaft。Linear bearings are used in conjunction with quenched linear drive shafts。A system of infinite linear motion。Load the ball and quench the drive shaft because it is point contact，Less allowable load，But when moving in a straight line，Minimum frictional resistance，High precision，Fast movement。]Divided into two major series namelyLMandLMEseries.codenameLMSeries for Asia，Southeast Asian countries，Japan，Korea，China et al.。 LMEThe series is mostly used in Europe，America，Germany，Italy and other regions。Two major departments

introduction：Plastic flow analysis software is one of the most powerful tools developed to improve the quality of injection modules，Examples of success abound。 Since the1975Since the commercialization of plastic flow simulation software，Molders have been thinking about the best use of it，Many people have been skeptical about its usefulness or accuracy。Molders who have doubts about plastic-flow simulations find that there is no good correspondence between the computer model and the actual molding results。This may be due to errors in the application of the software or unrealistically high expectations of its accuracy。 Some molders trust the accuracy of the software but doubt it

introduction：Because of deep groove ball bearings[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。]Is a high precision product，Its easy to fix if its not properly assembledTIMKENBearing channel caused damage，Cause bearing damage。Bearings should be equipped with special molds，Cant knock at will，When pressing into the shaft can only be small circle force，When pressing the big circle, only the big circle can be stressed。Required for assembly

introduction：one，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。]There are two main reasons for fracture: defect and overload，When the applied load exceeds the strength limit of the material, the fracture of the part is called overload fracture，Defects such as overheated tissue and local burn will also occur during bearing operation，Fault-induced fracture。 two，The bearing is in operation，Occasional axis

introduction： The quality index of lubricating oil can be divided into two categories：First, the physical and chemical properties of oil，The other is the application performance index of oil products。（Several main physicochemical indexes are introduced） a.colour：Lubricating oil is the same color as all substances，All have corresponding and fixed colors，It is related to the refinement of the base oil and the additives added。However, it will deteriorate due to oxidation during use or storage，And change the color，The degree of discoloration is related to the degree of metamorphism。If milky white，It indicates the presence of water or bubbles；darken，It indicates oxidation deterioration or pollution。 b.viscosity：Viscosity is the internal friction of lubricating oil

introduction：Reducer is a new type of reducer developed on the basis of cycloidal pin wheel drive,The transmission principle is shown in the figure1As indicated。Compared with similar reducer,Has a large deceleration ratio、Small size、High efficiency、Strong bearing capacity and other advantages,Therefore, it has been widely valued at home and abroad。On account ofRVReducer development time is short,So there are very few studies。90Early era,[1]Et al. began to study the use of involute variable tooth thickness internal and external gears instead of cycloidal pin wheel to achieveRVdrive;1993years,Yancy[2]Et al pairRVThe force analysis of the transmission was carried out;1996years,He Weidong[3] Et al pairRVReducer operation
