wastageIKOThere are many reasons for bearing，All factors affecting the design and manufacturing process will be related to 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。]Loss dependent，Its hard to analyze。But in general，Generally can be from the use of factors
Since the1930Made of thermosetting resinFAGbearing[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。]Since it first hit the market，inFAGbearing[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 application of various polymers and polymer-based mixtures in the field is increasing，The range of applications is also expanding。

1summarize There are two maintenance workshops of the mechanical automobile repair plant under my companyst／10．5mBridge crane，It is specially used for lifting and repairing machinery and cars。Due to the alignment of the engine cylinder when overhauling the car，The requirements for the rise and fall of the electric hoist are very strict，The amount of lift in a certain position must be very small，Otherwise the cylinder cannot be aligned。This requires that the electric hoist must have a point control，However, the electric hoist purchased from the manufacturer is equipped with this device，It does not have a strict lifting amount，This is very inconvenient for car engine maintenance。Due to this practical need，Our electrical control department for bridge cranes
Planetary reducer 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。]Analysis of common causes of fever：From the work environment，bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is fixed in the mechanical transmission process
ifIKOThe bearing is overheating，Everyone should be alarmed，Dont be careless。 causeIKOThe reasons for bearing overheating are mainly in the following aspects： （1）IKOBearing has been damaged，Should be replaced immediately。 （2）IKObearing[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。]Too little grease、
Molds of any complex geometry can be manufactured without the use of auxiliary process equipment or without the use of EDM etching，Direct metal laser sintering technology shortens the production time of complex molds，Reduce mold manufacturing costs。 Christmas tree injection mould made by direct metal laser sintering process。 The mold is made of steel powderDirect Steel， The thickness of the layer is20mm We can get it from EnglandCRDMLimited liability company adoptedEOSThe company produces equipment recognized inDMLSProduction capacity of direct metal laser sintering。A surname
1，IKOBearing maintenance、overhaul、And exception handling to maintain in good condition for as long as possibleIKOThe bearings original performance，Must be maintained、overhaul、To prevent accidents before they happen，Ensure the reliability of operation，Increase productivity、economy。Maintain operating standards best suited to the operating conditions of the machinery，Conduct regularly。The contents include，Monitoring operation、Replace or replace lubricant、Periodic disassembly inspection。 As maintenance matters in operation，There areIKOThe rotation sound of the bearing、Vibration、temperature、The state of the lubricant, etc。 2，IKObearing[bearing:bearing（“Bearing”
If the antifriction coating is directly electroplated on the lining metal，The tin in the coating is easy to diffuse to the lining，Make the bearing after working for a period of time，The tin content in the coating decreases to less than6％(Quality)。And whether it is copper base alloy lining or aluminum base alloy lining，They all contain a certain amount of copper，Tin diffused into the lining can form brittle intermetallic compounds with copper(Cu3Sn)。This not only reduces the mechanical properties of the coating，And it destroyed the structure of the lining，To reduce the overall mechanical properties of the bearing。The solution to this problem is to electroplate a layer of nickel or nickel-based alloy barrier between the lining material and the antifriction base layer(again
Gate valve refers to closing parts（ram）A valve that moves vertically along the center line of the path。Gate valves are mainly used for cutting off in pipelines。 Gate valve is a very widely used valve，General caliberDN≥50mmIt is used in all cutting devices，Gate valves are sometimes used for cutting devices of very small caliber，Gate valves have the following advantages： ①Low fluid resistance。 ②Less external force is required to open and close。 ③The flow of the medium is unrestricted。 ④Full time，The erosion of the sealing surface by the working medium is smaller than that of the stop valve。 ⑤Relatively simple in shape，The casting process is good。 Gate valves also have disadvantages
