introduction：Different from other sealing rings，YThe section of the sealing ring isYThe shape，It is a typical lip sealing ring。It is widely used in reciprocating sealing devices，Its service life is higher thanOV-sealing ring。YThe applicable working pressure of the sealing ring is not greater than40MPa，Operating temperature is-30～80℃。 YType sealing ring classification： YThe sealing ring varies according to the length and width ratio of the section，Can be divided into wide typeYV-sealing ring、Narrow typeYType sealing ring andYxType sealing ring, etc。wide-sectionYThe pressure resistance of type 2 sealing ring is slightly less than that of narrow typeYV-sealing ring，Can only apply toP<20MPaWorking environment，Narrow typeYThe type sealing ring can be used for working pressureP<32MPaThe occasion of。 YType sealing ring according to the height of the two lips is consistent，It can also be divided into unequal high lips for the shaftYV-sealing ring、Orifice with unequal high lipsYType seal ring and shaft hole common w

introduction：Those who have driven Toyotas and Volkswagens for a long time may know a thing or two，And for the prospective owner of the choice of car must be very tangled，The Internet says people have a lot of problems，But why are the streets full of people？therefore，Can not simply stand in the bad bad Angle to evaluate the good and bad of a brand。

introduction：In general, only a part of the roller of the running bearing bears the load at the same time，The area where this part of the roller is located is called the bearing bearing area。The load borne by the bearing，The size of running clearance will affect the bearing area。If the bearing area is too small，The roller is prone to slip in actual operation。 For wind power gearbox，If the design of the spindle adopts the double bearing support scheme，Then theoretically only torque is transferred to the gearbox。In this case，After a simple force analysis，It is not difficult to find that the load borne by the planetary support bearing is relatively small，Therefore, the bearing bearing area is often relatively small，Rollers tend to slip。Two single-row tapered bearings or two full roller cylindrical bearings are generally used in the design of wind power gear box。 We can improve the bearing area by properly pretightening tapered roller bearings or reducing the clearance of cylindrical roller bearings。Figure 2 s

introduction：Slope and roller type one-way clutches consist basically of cylindrical inner diameter outer rings、An inner ring with a slope and a set of rollers which respectively bear the spring force and are always in close contact with the inner and outer rings are composed。As long as the rotation of one raceway in its direction of motion has an effect on the other，This arrangement essentially ensures the immediacy of overtaking speed and guarantees the ability to drive immediately。The use of this type of one-way clutch can be suitable for overtaking in a variety of environments、Use of indexing and checking。 When used as an overrunning one-way clutch,The ramp roller type one-way clutch will be installed in this manner，Is to use the outer ring as a transcendental component。This is very important for high speed overtaking。In the use of the inner circle override，The centrifugal force acting on the roller will cause the overtaking speed to be limited。 When used as a one-way clutch,Slope roller type one-way c

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：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。

introduction：The mechanism of stainless steel rust prevention is the formation of dense oxide film by alloying elements，Isolated oxygen contact，Prevent further oxidation。So stainless steel is not“rustproof”。 304The material is rusty，There could be several reasons： 1.Chlorine ions are present in the use environment。 Chloride ions are widely present，Like table salt、Sweat track、seawater、Sea breeze、Soil and so on。Stainless steel in the presence of chloride ions，Corrode quickly，Even more than ordinary mild steel。 So there are requirements for the use of stainless steel environment，And it needs to be wiped down frequently，dusting，Keep clean and dry。（So we can give him one“Improper use”。）The United States has an example：A company used an oak container to contain a solution containing chloride ions，The container has been used for more than 100 years，It was planned to be replaced in the 1990s，Because the oak material is not modern enough，After stainless steel replacement16The container is leaking due to corrosion。 2.No solution tr
