How to choose rollIKOTypes of bearings、There are many types and sizes。To enable the mechanical device to perform the desired performance，Choose the best fitIKOBearings are crucial。 Choose forIKObearing，Many factors need to be analyzed，Research from all angles、Evaluation of relevant optionsIKObearing[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，It is used to reduce the friction coefficient in the process of power transmission and keep the center position of the shaft fixed
1、bruise(Brinell indentation) backdrop：After the motor is assembled，During a noise check，Detect noise。 trait：Continuous delivery“cla-cla…….”The voice of。 reason：Press the shaft into the shaft collar or 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。]Chamber hour，
Imported bearing[Imported bearing:Simply put, the import bearing agent refers to the sale of an imported bearing brand。The main brands of imported bearings arenskbearing，ikobearing，fagbearing，Of good quality，Of course, the price is not cheap。]There are several types of lubrication，And each type of bearing and each type of bearing are also different when using lubrication，This is more conducive toSKFbearing[SKFbearing:SKFThe full name is“Svenska Kullager-Fabriken”The Chinese transliterated name is“SKF”；SKFThe group is headquartered in Gothenburg, Sweden，Yes axis
Rolling 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。]Its a lot of mechanical parts that are produced，And the manufacturing accuracy requirements are very strict，There is a high level of specialization in skills，So about the vast majority of easily boughtSKFbearing[SKFbearing:SKFThe full name is“Svenska Kullager-Fabriken
The speed of the screw affects the heat and shear effect of the injection molding material transported and plasticized in the screw﹐So it is affecting plasticizing ability、Important parameters of plasticizing quality and molding cycle。The higher the screw speed，The stronger the plasticizing ability。Melting of plastics，It is basically the heat generated by the rotation of the screw，So the screw speed is too fast，Has the following effects：1.Thermal cracking of plastics；2.Accelerate the wear of the screw or cylinder。 The main advantage is increased plasticizing ability，Reduce plasticizing time。When the screw diameter is large or the screw groove is deep，If you cant reduce back pressure，Screw can be added Rotational speed to increase plasticizing speed，Reduce plasticizing time。 deserve
1 laying-off 2 Cold pier Cold pier can not only make steel forming，It can also make the composition of steel more uniform during the cold pier process，Effectively reduce defects（Be mixed with、Segregation and other bad tissue）content，Minimize the impact of defects in the workpiece organization，Prepare the shape and organization for the next process。 3 Soft grinding Soft grinding brings the shape of the workpiece closer to the required size，Save machining allowance for future processes，To prevent the subsequent processing of dimensional deviation can not be remedied。 4 quench+Low temperature tempering quench 1 aim：Heat the workpiece to Austenowitz
Performance characteristics ：1、Small offset output，Compact structure，Maximize the use of box space，Second level、Three levels in the same box。 2、Adopts integral casting box,Box structure stiffness is good,Easy to improve shaft strength and bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is fixed and reduced during mechanical transmission
FDM Selective cladding of filaments（Fused Deposition Modeling）Rapid prototyping is a process that does not rely on laser as a forming energy source、The molding method of heating and melting various silk materials，For shortFDM。 Principle room for selective cladding of filamentous materials，The heating nozzle is under the control of computer，According to the section profile information of the product parts，As aX-YPlane motion。Thermoplastic filament material（If diameter is1.78mmPlastic filament）The wire feeder is sent to the nozzle，And in the nozzle heat and dissolve into semi-liquid
FAGbearing[FAGbearing:The main shaft bearing is made of a solid inner ring、Outer ring、The ball、And a single row angular contact ball bearing consisting of a cage assembly with a solid window cage。]Same as the axle sleeve,seat,Bearing hole general clearance with transition,Two-way thrust bearing ring should be fixed on the shaft,To prevent relative rotation of the axis Mounting method of bearing,Under normal circumstances,Most of the time axes,So the inner ring is drawn to the shaft,Bearing and bearing clearance fit outhouse Bearing mounting,You should check the ring and bushing center line of the shaft perpendicular to the dial gauge fixed on the tank,Will face the touchFAGbearing[FAGbearing:Main shaft bearing Yes
