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。]Installation is good or not,Will affect 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,Be used for
1.The processing of the ring: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 processing of the inner and outer rings varies according to the raw material or blank form,The process before turning can be divided into the following three types,The whole processing process is:Bar or pipe material(better The material needs to be forged and annealed、
Clutch 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。]It is common for faults to appear during operation,So theres no need to be strange。A fault was revealed,Judgment and disposal is the key。 1.bearing[bearing:bearing(“Bearing”,Japanese person“Axial receptor”)It is fixed in the mechanical transmission process
GE…E、GE…ES、GE…DSRadial joint 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 structure type and overall dimensions E (
KOYOBearing cleaning:takedownKOYOBearing inspection,First recordKOYOBearing appearance,Verify the residual amount of lubricant,After taking a sample of the lubricant for inspection,washKOYObearing[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。]。As a cleaning agent,Regular gasoline、kerosene。 disassemble
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。]The temperature of,Generally haveFAGbearing[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。]The temperature outside can be inferred,If the oil hole is used, the temperature of the bearing outer ring can be measured directly,Is more appropriate。 usual,FAGbearing[FAGbearing:Principal axis
Generally speaking,Stainless steel 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。]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,To reduce motion

①、Shrinkage cavity:Molten steel in the process of condensation after pouring,Holes form in the center of the ingot due to volume shrinkage,Called shrinkage。In order to reduce the harm of shrinkage steel,Thus pouring in molten steel,A reasonable process should be adopted in the crystallization process,The hole created by the shrinkage of the volume moves towards the head of the ingot,After the ingot is opened,Cut away the shrinkage hole,however,Due to pouring、Improper cooling process,Such as Dingqi unreasonable,Ingot head insulation is insufficient,The amount of cutting off the head of ingot after opening is less,The shrinkage hole remains in the steel,At low power inspection,It shows up。 ②、White spot:Cross section of steel sample after pickling
The die and press are used to determine the stamping quality、Precision and production efficiency are two key factors。Advanced presses are only equipped with advanced molds,To make the most of it,Achieve good results。The development direction of the mold is: one、Make full use ofITTechnology development mold design、manufacture。User on press speed、precision、Changing efficiency and other aspects of the increasing requirements,Promote the development of mold。The body and engine are the two key components of a car,Auto body mold, especially large and medium-sized covering parts mold,Its technology intensive,Reflect the level of contemporary mold technology,It is an important part of body manufacturing technology。car
