introduction：Support seat for bearing requirements The structure of the support end is simple，By bearing seat only、Elastic retaining ring、Bearing composition，An ordinary radial ball bearing is adopted in the support to support the end of the lead screw。Since this bearing only provides radial constraints，And the axis is free，No restrictions imposed，When the length of the lead screw is slightly extended because of heat deformation，The support end can make a small amount of axial float，Ensure that the lead screw is still in a straight line。 Ball screw support seat for bearing requirements Ball screw pair requirements for rolling bearings，The similarity with the requirements of the spindle and the drive shaft for rolling bearings is，Rolling bearings should have sufficient accuracy and fatigue life。But the differences are also striking，Ball screw mainly bear axial load，In addition to the lead screw weight，Generally no radial load。 therefore，The axial accuracy and axial stiffness of ball screw pair rolling beari

introduction：Slewing bearing seat installation and maintenance The installation surface should be smooth and clean，Remove all excess material such as paint residue、bead、burr。When cleaning, be careful not to let the solvent penetrate into the inside of the slewing support，Do not use solvents that damage the sealing material。The mounting surface should be dry before assembly、No lubricant。Measures should be taken to protect workers and the environment。 Slewing support seat positioning ： The inner and outer ring raceways of the slewing bearing have a soft belt，Should be placed on both sides of the main load plane。That is, it is staggered from the main load area90The degree of。The soft band has a blockage or is beaten up“S”Markers。In addition, it is necessary to check the coincidence between the slewing bearing and the mounting surface，A gauge is usually used to check，If its a bad fit，It should be filled with appropriate materials。After the slewing support is installed, welding on the support is prohibited。

introduction：Angle steel commonly known as Angle iron、Its a long piece of steel with two sides angled perpendicular to each other。There are equal angles and unequal angles。The two sides of an equilateral Angle are equal in width。Its specifications are wide by side×Hem width×The thickness of the edge is expressed in millimeters。Such as“∠50×50×5”，That is, the side width is50millimeter、Edge thickness5Millimeter equal Angle steel。Can also be indicated by model，The model number is the number of centimeters of the width of the side，Such as∠5#。The model does not indicate the dimensions of different side thicknesses in the same model，Therefore, the edge width of the Angle steel in the contract and other documents、The side thickness is complete，Avoid using the model number alone。The specifications of hot-rolled equal-edge Angle steel are2#-20#。 Angle steel can be composed of different stress members according to the different needs of the structure，It can also be used as a connection between components。It is widely used in various

introduction：How to put the steel ball in the screw nut A kind of metal abrasive for screw steel ball，The main varieties are stainless steel balls、Cast steel shot、Aluminium shot、Wire shot cutting、Abrasive pill、Copper shot。Steel balls are widely used in non-ferrous metal die casting、Casting part，Aluminium profile、Lead screw、Auto parts、Machinery manufacturing industry、hardware、Surface treatment for the pump and valve industry。The main focus is to remove the oxide skin on the surface of the product、Edge surface burrs、Surface roughening、Matte suburban fruit、Leveling and strengthening、Derusting treatment。 Mounting method of ball screw： The ball screw nut pair is only used to bear axial loads，Radial force、The bending moment will make the ball screw nut pair additional surface contact stress and other loads，This can cause permanent damage to the lead screw。Proper installation is a prerequisite for effective maintenance。therefore，Ball screw When the nut pair is installed to the machine，The following points should be noted：

introduction：Lead screw nut characteristics and working principle Working principle of ball screw nut： A curved spiral groove is machined on the lead screw and nut，They form spiral raceways when fitted together，And the raceway is filled with balls，When the lead screw is rotated in relation to the nut，Axial displacement occurs between the two.The ball can be rolled along the raceway.Reduce friction resistance.After the ball has been rolled several times on the lead screw，Through the return guide device（baller）.Roll back one by one between the lead screw and the nut.Form a closed loop pipeline。 Lead screw nut features： At drive，Ball and screw、There is basically rolling friction between the nuts.It therefore has the following advantages 1)、High transmission efficiency The transmission efficiency of ball screw pair is very high，reachable92%-98%，Its an ordinary lead screw drive2-4times 2)、High positioning accuracy and repeated positioning accuracy
