CNC machine tool industry demand is growing rapidly,But the industry is increasingly competitive,The whole industry presents a strong constant strong situation,Led the machine tool reducer industry growth such as rainbow,Some of the components of the industry are booming。 Decelerating machinery manufacturing industry belongs to the basic equipment industry of the national economy,Its development is closely related to macro-economy。03、04With the rapid growth of macroeconomics in China,The reducer industry is showing a good development trend,The growth rate is the highest in recent years。05years,Reducer industry industrial production、pin
Stainless steel is imported bearing[bearing:bearing,thkbearing,trbearing,NSKbearing,NTNbearing,SKFbearing,NACHIbearing,KOYObearing,HCHbearing,IKObearing]One of the most common bearings[bearing:bearing,thkbearing,trbearing,NSKbearing,NTNbearing,SKFbearing,NACHIbearing,KOYObearing,HCHbearing,IKObearing]material,Its also the most practical,Of course, its cost also fluctuates with the price of steel,
KOYOThe bearing temperature rises slowly in operation,usual。 1-2Hour (s),To achieve a stable state。Deep groove ball bearing[bearing:bearing,thkbearing,trbearing,NSKbearing,NTNbearing,SKFbearing,NACHIbearing,KOYObearing,HCHbearing,IKObearing]The normal temperature due to machinery,hot,The speed and heat capacity of the load vary。If lubricated,Appropriate equipment department,bearing[bearing:bearing,thkbearing,trbearing,NSKbearing,NTNbearing,SKFbearing,NACHIbearing,KOYObearing,HCHbearing,IK
Lubrication is the use of oil、Grease or other fluid material,So that the contact surfaces between moving objects can be separated,To reduce friction、Reduce wear,Reduce the temperature,Corrosion prevention,The important role of damping vibration。 one、Classification of lubrication Generally speaking according to the state,Lubrication can be divided into: 1.Liquid lubrication; 2.Semi-liquid lubrication; 3.Boundary lubrication。 two、General principles for selecting lubricants (1)First of all, choose according to the working conditions。
one、Shaft and bearing[bearing:bearing,thkbearing,trbearing,NSKbearing,NTNbearing,SKFbearing,NACHIbearing,KOYObearing,HCHbearing,IKObearing]Room tolerance control and selection Genuine and licensedIKOBearing pressed into bearing[bearing:bearing,thkbearing,trbearing,NSKbearing,NTNbearing,SKFbearing,NACHIbearing,KOYObearing,HCHbearing,IKObearing]After rotation should be flexible without feeling blocked,If there is obvious rotation is not flexible,This means that the size of the axis is too large。Such asIKObearing
one、 Technological development background In the modern machinery manufacturing industry,The application of CNC machine tools is becoming more and more popular,Especially in the process of our countrys transition from planned economy to market economy,Machinery manufacturing industry is facing more fierce market competition,Enterprises for survival and development,Constantly adopt new technologies,Improve product quality,Improve production management level。 Many countries are big.、Medium-sized enterprise,Remodeled after several five-year plans,Introduce CNC machine tools in batches and stages,Form a numerical control section or workshop,Because CNC machine tools are expensive,Long renewal cycle,So different ages、Different production
SKFImported bearing[bearing:bearing,thkbearing,trbearing,NSKbearing,NTNbearing,SKFbearing,NACHIbearing,KOYObearing,HCHbearing,IKObearing]The function of coordination is to makeSKFImported bearing[bearing:bearing,thkbearing,trbearing,NSKbearing,NTNbearing,SKFbearing,NACHIbearing,KOYObearing,HCHbearing,IKObearing]The stationary ring and the rotating ring are respectively associated with the mounting position
one、Center migration method 1、 Butt bearing[bearing:bearing,thkbearing,trbearing,NSKbearing,NTNbearing,SKFbearing,NACHIbearing,KOYObearing,HCHbearing,IKObearing]In the ring、Salvage of the outside diameter First of all, the defects of the parts(Asymmetrical type)Dimensions are accurately measured,Calculate the minimum grinding amount(The amount of grinding to the finished product size deviation)M,The part is then center offset during grinding(Shift in the direction of increasing the amount of wear at the defect),The maximum offset isM/2,That is, the grinding amount is relatively increased at the defect,heavy
The motor is generally in use according to the time of use2000Cleaning and refueling should be carried out after hours。KOYOThere are two cleaning methods for bearings: one、Hot oil cleaning method due to long use,Soft dry oil or rust resistant paste hardening of the mouth bearing[bearing:bearing,thkbearing,trbearing,NSKbearing,NTNbearing,SKFbearing,NACHIbearing,KOYObearing,HCHbearing,IKObearing],Should be submerged in100—200℃In the hot oil,Hold it with pliersKOYObearing,Use wool
The use factor mainly refers to the installation adjustment、Service and maintenance、Whether the maintenance and repair meet the technical requirements。On the basis ofSKFBearing mounting、Use、maintenance、Technical requirements for maintenance,In operationSKFThe load borne by the bearing、Rotational speed、Operating temperature、Vibration、Noise and lubrication conditions are monitored and checked,If an exception is found, find the cause immediately,Make adjustments,Get it back to normal。Installation conditions are one of the first factors in use,bearing[bearing:bearing,thkbearing,trbearing,NSKbearing,NTNbearing,S
