INAbearing[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。]After installation，To check that the installation is correct，An operational check is required。Small machines can be turned by hand，To make sure the rotation is smooth。Check items for foreign bodies、scar、Poor operation due to indentation，Due to poor installation，The torque caused by poor machining of the mounting seat is unstable
A new generation for car roof productionBaynat®Polyurethane rigid foam is characterized by improved thermoplastic properties30%。Head of Automotive Roof Products Group, Polyurethane Business Unit, Bayer Material TechnologyKlaus-W.Hulandsaid：“We can improve the thermoplastic properties of lightweight materials without affecting their self-supporting properties。same，We can also further optimize the displacement of the car。”The density of polyurethane per cubic meter is22Kilogram and28to30kilogram。Due to small surface area and other reasons，The roof of the car cannot withstand the high mechanical load，And low-density variant products are exactly
Reducer is a mechanical transmission device in many fields of national economy，The product categories involved in the industry include all types of gear reduction machines、Planetary gear reducer and worm reducer，A variety of special drives are also included，Ruzin Speed gear、Speed regulating device、And various types of composite transmission devices, including flexible transmission devices。Products and services are related to metallurgy、coloured、coal、Building materials、boats、Water conservancy、electricity、Engineering machinery and petrochemical industries。 2012-2016China reducer industry production and sales demand forecast and transformation and upgrading analysis speech》reveal，2008After the outbreak of the international financial crisis，State response
flowIKOBearings if used in harsh environments，Unidirectional 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。]Sealing ring and sealing cover are essential，Because they keep dirt out，Extension bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is fixed and reduced in the mechanical transmission process
1．Grinding wheel carrier The grinding wheel holder consists of a housing、Spindle and 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 transmission device and the sliding saddle are composed。Structure and performance of grinding wheel spindle and its supporting part，It directly affects the machining accuracy and surface roughness of the workpiece，It is the key to the grinding machine and grinding wheel frame components。Grinding wheel spindle
first、The structure design is reasonable and advanced at the same time，There will be longerIKOImported 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。]Life span。Bearings are generally manufactured by forging、Heat treatment、turning、Grinding and assembly and other processing processes。The rationality of each processing technology、advancement、Stability also affects the life of the bearing。The heat treatment and grinding processes that affect the quality of the finished bearing，Often with bearing failure
The main transmission structure of planetary reducer is:Planet gear,Sun wheel,Outer gear ring. Planetary reducer for structural reasons,Single-stage deceleration minimum3,The maximum generally does not exceed10,Common deceleration ratio is:3.4.5.6.8.10,Reducer series generally do not exceed3,But there are parts of large reduction than custom reducers have4Stage reduction. Relative to other reducers,The planetary reducer has high rigidity,High precision(A single stage can do it1Within points),High transmission efficiency(Single-stage in97%-98%),High torque/Volume ratio,Lifelong maintenance free and other features. Because of these characteristics,Planetary deceleration
The characteristics of each type of injection machine are as follows： 1、Full hydraulic injection machine in molding precision、There are many unique advantages when it comes to products with complex shapes，It comes from a traditional single cylinder filled with liquid、The multi-cylinder liquid-filled type has developed to the current two-plate direct pressure type，Among them, the two-plate direct pressure type is the most representative，But its control technology is difficult，High machining accuracy，Hydraulic technology is also difficult to master。 2、The all-electric injection machine has a number of advantages，Especially in environmental protection and energy saving advantages，By report，At present, the more advanced all-electric injection machine can save electricity70%，In addition，In use
A judgment of whether it is reusable，Be consideringKOYOBearing damage degree、Mechanical property、significance、Operating condition、Until the next inspection period。but，It cannot be used again if it has the following defects，Must be replacedKOYObearing： (1)Inner ring、Outer ring、Rolling element、A crack or notch in either of the cages； (2)ferrule、There is a break in any one of the rolling elements； (3)Raceway surface、flange、There are significant sticking injuries on the roller； (4)Cage wear is significant，Or the rivet loosens significantly；
