The following describes the main causes of three kinds of ball screw problems and their prevention methods。 1、No or insufficient preload When the ball screw is placed vertically，The nut will cause rotation 2 to slip due to its own weight：The lead screw without preloading will have a certain gap，Therefore, it can only be used for machines with low operating resistance，But as long as the concern is that the positioning accuracy is not required。 Our company uses different preloading amounts for different applications，And adjust the pre-pressure before shipping；Therefore, please inform the operation of the equipment in detail before you order the ball screw。 2、Torsional displacement
If you buy fake ball screws to use，It can cause damage to the machine，Unable to work，This is a very big loss for the enterprise，Then how to identify the import ball screw true or false?Lets take a look below！ Simple identification of ball screw true or false-Its just a different setup，Look at the ball screw pair。Look at the size and space of your installation，Test Rockwell hardness，Imported ball screw specifications。At mostHRC60.。Also consider the load of the screw。 Methods described online： Dial indicator utilization，On a horizontal platform，Test at both ends and in the center，
What are the common identification methods of bearings？Lets study together，Learn about common bearing identification methods！ The common identification methods of bearings are： 1.Whether the outer packing is clear In general，The factory brands have their own specialized designers for external packaging design，And arrange the production of factories with satisfactory production conditions，Therefore, the packaging is very clear from lines to color blocks，In no uncertain terms，（Some of the accessories of imported brands have unique designs specifically designed to protect their intellectual property rights）。 2.Whether the steel seal is clear&nb
1.Bearing load The size of the load on the bearing、Direction and nature，It is the main basis for selecting the bearing type。 When selecting the type of bearing according to the size of the load，Because the main components in roller bearings are in line contact，Suitable for bearing large loads，The deformation after loading is also small。And ball bearings are point contacts，Suitable for light or moderate loads，Therefore, the load is small，Ball bearings should be preferred。 When selecting the bearing type according to the direction of the load，For pure axial loads，Generally use thrust bearings。Small pure axial loads can be selected thrust ball bearings；larger
Four classifications of linear guides： The basic method of linear guide section is based on the section shape of linear guide，Sliding linear guide(Sliding block)rectangular、VThe shape、Round and dovetail shape, etc，symmetryVShape asymmetryVShape rectangular dovetail shape circular convex shape45The degree of。 1、Rectangular linear guide The rectangular silver guide rail is characterized by its simple structure，manufacture、Inspection and repair are easier。Rectangular linear guides can be made wider，Therefore, the bearing capacity and stiffness are large，Widely used。The disadvantage is that it cannot be automatically compensated after wear
How to prevent the bead of the linear guide slide from falling off？Lets follow Feng Ye to understand how to prevent the beads of the linear guide slide from falling off。 Nowadays, with the linear guide in our machine tool CNC industry more and more widely used，Subsequently, the number of feedback problems gradually increased，Take the rail for example，Every now and then I get feedback from customers：Linear guide used for a while later，The bead of the linear slide is coming off，There is also a case where the consumer does not operate properly before use，The bead that caused the rail slide to fall out on its own，So how to prevent this from happening？ below
Belt conveyor in the work often appear belt slip situation，Belt slip will have a great impact on the normal conveying function of the conveyor，In turn, it affects the efficiency of the entire production system。Therefore, we cannot take lightly the seemingly insignificant problem of belt slip。So if you want to solve the belt slip problem，We first need to have a detailed understanding of the causes of belt slip。 1、When the belt conveyor starts，The initial tension of the belt is insufficient When starting the belt conveyor，If the initial tension of the flat belt is insufficient，Can not be tightly fitted to the conveyor surface。So the belt is running
The positioning pin should be a fixed-point positioning part with a very high frequency of application in the field of industrial automation。Under normal circumstances, the positioning pin is fixed in a small space，And often directly exposed to the air。Therefore, the part pressure on the positioning pin is very large，And also faced with a more complex working environment。 Under this double pressure, we want to extend its service life as much as possible，How to do the maintenance of the positioning pin is very important。And the installation process of the positioning pin is also a lot of attention，In the following section, we will introduce these two aspects in detail。&nb
When selecting cross roller guide specifications，In addition to the need to consider the accuracy of the guide rail and rated load，Also consider the length of the guide rail and the number of cylindrical rollers。 Calculate the length of travel and the number of cylindrical rollers Cross roller guides must consider the length of travel when selecting specifications，Load Indicates the size of the load，And strictly follow the steps to choose。 1.Calculate the length of the slide rail The length of the slide rail to the length of the travel used1.5More than times as a rough standard。 2.computezuiLarge stroke length The length of the stroke used is generally selectedzuiLarge stroke
The raw material of the guide shaft is generally selected as chrome plated rod or cold drawn rod，Because of the particularity of its use environment，The guide shaft usually requires surface treatment after production。The main function of the guiding shaft is to play a guiding role，However, it needs to be used with different parts in different working scenarios。The main application scenarios of the guide shaft include:Linear motion、Rotating motion and pillar。 one、Different environments supporting parts 1.The guide shaft is in straight line motion，The guide shaft is usually supported with the guide shaft、Oil-free bushing、Linear bearings and other supporting use。Such as，Linear guide shaft is used to match with linear bearing to form linear motion
