introduction：NSKbearing[NSKbearing:Seiko Co., LTD（NSK LTD.）Be established in1916years，It is the first manufacturer to design and produce bearings in Japan。NSKThe function of the bearing fit is to makeNSKThe stationary ring and rotating ring of the bearing are respectively the stationary part of the installation part(Usually a bearing seat)And rotating part(Usually an axis)Solidify together，Thus, the basic tasks of transferring the load in the rotating state and defining the position of the moving system relative to the stationary system are realized。]One kind of noise is generated by the bearing itself，That is, the inherent noise of bearings;The other is the noise generated after the bearing is installed，With bearing itself

introduction：KOYOThe bearing inner ring is a tight fit with the shaft，The outer ring is loosely matched with the shell，The bearing can be used by press[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。]First pressed on the double row angular contact ball bearing，The shaft is then fitted into the housing together with the bearing，An assembly sleeve of soft metal material is padded on the bearing end face during pressing（Copper or soft steel pipe）。loading

introduction：Electromagnetic clutch adjustment precautions 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，Specify specific requirements，If the brake spacing is adjusted too small，So that the friction plate can not be completely removed，As a result, the motor load increases or the belt slips，The machinery department can operate normally。If the starting distance is adjusted

introduction： The production of magnesium alloy die-casting die forging has reached a mature level of industrialization。Selection of process and equipment for industrial production of magnesium alloy casting and forging parts，Have the following suggestions： 1．Common magnesium alloy（Flammable magnesium alloy）Production of casting and forging parts The first choice is the hot chamber horizontal magnesium alloy die casting die forging machine。Its advantages are，There is no complex protection system to prevent magnesium alloys from burning。 It is suggested to adopt the parallel heat preservation and melting system of two furnaces，A furnace is a heat preservation furnace，Do not open with sealing during production，Add protective gas seal protection，Another furnace is used specifically to melt magnesium ingots。Melting furnace proposal

introduction： one、Helical gear reducer common problems and causes 1.Reducer heat and oil leakage In order to increase the rate，Worm gear reducer is generally made of non-ferrous metal worm gear，The worm is made of harder steel。Because it is a sliding friction drive，More heat will be generated during operation，The thermal expansion of the reducer parts and seals is different，Thus a gap is formed on each mating surface，The lubricating oil thinns as the temperature rises，Leak prone。There are four main reasons for this，First, the material collocation is unreasonable;Second, the quality of the meshing friction surface is poor;Third, the selection of the amount of lubricating oil added is not correct
