introduction：ikoHow to install needle roller bearings ikoNeedle roller bearings are fitted with long thin rollers（Roller length is diameter3~10times，The diameter is generally not greater than5mm），Thus the radial structure is compact，Its inner diameter size and load capacity are the same as other types of bearings，Minimum outside diameter，Especially suitable for bearing results with limited radial mounting size.Needle roller bearings according to the use of different occasions，Bearings without inner rings or needle roller and cage assemblies are available，At this time, the journal surface matched with the bearing and the surface of the housing hole are directly used as the inside of the bearing、Outer rolling surface，In order to ensure that the load capacity and operating performance are the same as that of the ring bearing，The hardness of the shaft or housing hole raceway surface，Machining accuracy and surface quality should be related to bearing rings. The combined needle roller bearing is a bearing unit composed of a

introduction：abbaScrew maintenance abbaThe screw usually has the following ways to maintain： （1）Elimination of axial clearance。After the ball screw is disassembled，In order to ensure the reverse transmission accuracy and axial stiffness，Axial clearance must be eliminated。The method of eliminating the clearance of the double nut ball screw pair is，Use the relative axial displacement of the two nuts，The balls in the two ball nuts are attached to the opposite sides of the threaded raceway。When the axial clearance is eliminated by pretightening in this way，It should be noted that the pre-loading force should not be too large，Otherwise, the no-load torque will increase，Thus reducing transmission efficiency。

introduction：abbaScrew agent teaches you maintenance Ball screws are usually used in situations where precise positioning is required。High mechanical efficiency、Low transmission torque and almost zero axial clearance, This makes the ball screw an important device in applications such as tool positioning and aircraft aileron drive。however, Resistance and heat generated by continuous work can cause great friction and positioning errors。 Design factors that increase friction in the ball screw also increase torque, And in turn affect the positioning accuracy。When the ball is compressed between the ball screw nut and the screw shaft, The resulting wedge effect is a potential source of friction。On the turn, The ball is usually squeezed against the nut; Reverse time,The ball is squeezed against the screw shaft。Because the sliding friction coefficient is much larger than the rolling friction coefficient( Not move0.1～0.3;roll0.001～0.003) ,The wedge effect greatly increases the torque。 When the ball screw shaft vibrates at a fixe

introduction：abbaLead screw material Select and useabbaBall screw material time，Item by item inspection is required in accordance with national standards，Especially the surface quality of raw materials（appearance，shape，Surface defect），Chemical composition and internal quality，Only qualified materials can be put into production。 1.For ordinary precision soft screw，Because its application is very common，Easy processing，Therefore, materials with low performance requirements can be used，It is mostly used in some medium carbon steel and medium carbon low alloy steel。 2.For high precision precision soft screw，Its accuracy requirements are in6Lv. Or above，And mostly used for light loads，Structure with low operating frequency，Its material requirements，In addition to similar to ordinary lead screw，It also requires good grinding performance of the material，It is not easy to produce wear cracks，Low grinding surface roughness，Therefore, rated steels with higher carbon content are commonly used。
