introduction：Bearings are generally considered to be an important component of system engineering to improve working surface reliability[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。]（INAThe work function of the bearing is lost in its delineation，A phenomenon that causes failure or non-operation as a failure is called（Bearing failures can be divided according to their normal failure and two early failures，This is mainly aimed at points

introduction：Reducer is a kind of widely used in all walks of life，What are the installation and precautions for the reducer？Tianjin Golden Light transmission technology believes that ensuring installation problems and paying attention to problems in use can save users money and time。 1.Mounting reducer，Attention should be paid to alignment of the transmission center axis，The error shall not be greater than the compensation amount of the coupling used。Good alignment can extend service life，And obtain the ideal transmission efficiency。 2.When installing the transmission on the output shaft，Hammering is not allowed，Assembly fixtures and internal threads at shaft ends are usually used，Press the drive in with bolts，Otherwise it may cause
