"Chinese 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 pricing is only for imported bearings[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。]valence0.5-0
1)Surface cleaning：Cleaning must depend on the nature of the surface of the rust-proof substance and the conditions at the time，Select the appropriate method。Solvent cleaning method is commonly used、Chemical cleaning and mechanical cleaning。 2）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
normal，If the oil-free bearing is used correctly[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。]，Can be used until fatigue life is reached。But there will be accidental premature damage，Intolerability to use。This early damage，Relative to fatigue life，Limits on the use of qualities called faults or accidents。Many causes are installation、Use、Lubricated no
1.Contact fatigue failure Contact fatigue failure refers to the 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 working surface is subjected to alternating stress and produces failure。Contact fatigue spalling occurs in bearings[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is used to fix and reduce load friction during mechanical transmission
Grease lubricated with pre-sealed type bearings[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 method of filling grease，And fill an appropriate amount of grease inside the housing，A filling method of fat supply that is supplemented or replaced at regular intervals。In addition，Yes, there are manyT
Article title:Working principle of reducer Detailed content: In a nutshell,It is the use of all levels of gear transmission to achieve the purpose of reducing speed.The reducer is composed of gear pairs at all levels.For example, using small gears to drive large gears can achieve a certain goal of deceleration,Then adopt the multi-level structure,You can significantly reduce the RPM. The reducer is generally used for transmission equipment with low speed and high torque，Knob motor.The power of the internal combustion engine or other high-speed operation is engaged by the large teeth on the output shaft through the small number of teeth on the input shaft of the reducer
Hydraulic oil quality is good or bad，Not only affect the normal work of construction machinery，And can cause serious damage to the hydraulic system components。Now combined with the work practice summed up several cases in the absence of special testing instruments，Simple method to identify the quality of hydraulic oil。 1Identification of hydraulic oil moisture content (1)Visual method：If the oil is milky white and cloudy，It means that the oil contains a lot of water。 (2)Combustion method：Use clean、Dry cotton yarn or cotton paper with a little oil to be tested，Then light it with fire。If found“sputter”The sound of the explosion
High temperature 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。]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、Caused by indentation
