introduction：In moving parts，Wear of parts due to prolonged friction，When the gap between the shaft and the hole is worn to a certain extent, the parts must be replaced，Therefore, designers choose lower hardness when designing、The material with better wear resistance is the bushing or bushing，This reduces shaft and seat wear，Replace the bushing or bushing when it is worn to a certain extent，This can save the cost of replacing the shaft or seat，Generally speaking，Interference fit is adopted between bushing and seat，And the shaft adopts a clearance fit，Because you cant avoid wear and tear no matter what，Can only prolong life，Shaft parts are relatively easy to process；There are also some new designers who dont like this design，It is thought that this increases the cost at the time of manufacture，But after a period of use，Maintenance should still be modified in this way，But it is easy to reduce the accuracy of the equipment，The reason is simple.，Secondary processing is unable to ensure the position of the seat hole center of

introduction：Glad to discuss bearing knowledge with you again，Our problem today is that roller bearings and ball bearings have a larger number of negative loads？ I think some of you know that ball bearings are point-contact，So low friction can lead to high speed，But because the contact point is small, it can not withstand large loads。And roller bearings are line contacts，So the friction is not as high as the spin of the ball，But because the contact area is large, it can withstand large loads。So there is no doubt that the roller bearing wins！ But how much do you know about roller bearings？Lets take a look at what is roller bearing，Whats so special about it！ Roller bearing：Its a short cylinder、A rolling bearing with a cone or waist drum roller as a rolling body。Mainly centripetal short cylindrical roller、Double row centripetal spherical roller、Conical roller and thrust roller and other structural types。 concept：Roller bearings are mainly centripetal short cylindrical rollers、Double row centripetal spherical roller、Conic

introduction：Structure type Aligning roller bearings are divided into：Cylindrical bore、Conical inner hole。 The taper of the holes in the cone are1：12After the code isKSelf-aligning roller bearing（153000Type OR113000type）and 1：30After the code isK30Self-aligning roller bearing。Such bearings are matched with conical shafts，The axial movement of the inner ring can adjust the radial clearance of the bearing。 postcode： Codename the postpositionK、K30Tapered hole aligning roller bearing，Mount on matching tight-fitting sleeve，Then it becomes the post-codeK+HType sumK30+HD-type bearing。The bearing can be mounted on an optical shaft without a shoulder，Suitable for occasions where bearings need to be installed and removed frequently。In order to improve the lubrication performance of bearings，An annular oil groove is arranged in the bearing outer ring and three oil holes are drilled with uniform distribution，The following code isW33。 use： Mainly applicable cage：Stamped steel reinforced cage（suffixE，Very few in China）。Stamped st

introduction：Im sure you all know that，But let me tell you again，As we all know, deep groove ball bearings are the most common type of rolling bearings。The basic type of deep groove ball bearing consists of an outer ring，An inner ring、A set of steel balls and a set of cages。 Deep groove ball bearing types are single row and double row two，The deep groove ball structure is also divided into two kinds of sealed and open structures，The open type means that the bearing does not have a sealed structure，Sealed deep groove ball is divided into dustproof seal and oil proof seal。 So deep groove ball bearing bearing characteristics you know how much？ Deep groove ball bearing is the most representative rolling bearing，versatile。Suitable for high speed or even very high speed operation，And very durable.，No frequent maintenance required。The friction coefficient of this kind of bearing is small，Limit speed height， Simple structure，Low manufacturing cost，Easy to achieve high manufacturing accuracy。 Varied in size range and form，

introduction：Cold-formed steel is one of the many varieties of steel，Strip steel of a certain width，Pass through a set of longitudinally arranged rolls at normal temperature，Stepwise deformation，To meet the requirements of the shape and size，Then cut to the corresponding length after determining the size。This product is cold-formed steel。Of course，You can also use stamping，Cold-formed sections are obtained by bending or drawing。But the roll bending forming method is suitable for large-scale industrial production，Product quality，Processing cost，The production efficiency is unmatched by other methods，It is the main production process of cold formed steel at present。If the unit is equipped with welding equipment(Such as high-frequency welding，Argon arc welding, etc）It can also produce cold formed steel with closed section。

introduction：Forging is the use of forging machinery to apply pressure to metal billets，It produces plastic deformation to obtain certain mechanical properties、Processing methods for forgings of certain shapes and sizes，Forge and press（Forging and stamping）One of the two major components。Forging can eliminate the defects of metal in the smelting process such as loose as cast，Optimize the microstructure，At the same time, due to the preservation of the complete metal flow line，The mechanical properties of forgings are generally better than castings of the same material。High load in related machinery、Important parts with severe working conditions，Except for the simple shape of the plate can be rolled、Profiles or welds outside，Use more forgings。
