KOYORolling bearing is an important mechanical component，Whether the performance of a mechanical equipment can be fully developed depends on whether the lubrication of the bearing is appropriate，So to speak，Lubrication is guaranteedKOYOThe necessary conditions for the normal operation of rolling bearings，It plays an important role in improving the bearing capacity and service life。No matter what form of lubrication is used，Lubrication in rolling bearings can play the following roles：（1）Reduce friction between metals，Slow its wear。（2）The formation of oil film increases the contact area，Contact stress reduction。（3）Ensure that the rolling bearing can be under high frequency contact stress，It works well for long periods of time，Prolonged fatigue
Vertical ground mounting screw nut link how to ensure that the nut does not slide（non-self-locking）What about the state of？The following is a detailed analysis of this problem：First of all, your question is ambiguous：A、The question you have to ask is how can the design function be guaranteed?B、Or how to operate in the assembly process of the product?These are two completely different concepts。1、First of all, lets talk about how to ensure the design function of the following figure(I drew a suggested expression mechanism)：Generally speaking，A structure of this kind，We use the motor to lock down the vertical load，So in the choice of vertical motor，We need to choose the motor with the lock function
As everyone knows，The selection of the coupling has always been a headache for enterprises，I believe many companies and engineers are well aware of this。About the selection of plum coupling，In addition to depending on the actual operating conditions，You must also know the specific parameters。Below, we Fengye mall technical engineers will introduce the basic technical parameters of the plum coupling in detail，Here are a few points for your reference：1.Nominal torque Nominal torque，It can be understood as the torque that the plum coupling can transmit normally。So where does this nominal torque come from？Of course it didnt come out of thin air，Rely on scientific calculations，Get a scientific calculation
This paper gives a detailed introduction to the calculation method of the bearing capacity of the planetary gear reducer，The following is for reference only：The calculation of the gear strength of planetary gear reducer can be made by the formula of fixed shaft gear transmission，However, the structural characteristics of planetary transmission need to be considered（Multiplanetary wheel）And movement characteristics（The planetary wheel has both rotation and revolution）。Under normal conditions，NCWType planetary gear drive，Its bearing capacity mainly depends on the external meshing，Therefore, the strength of the gear with external meshing must be calculated first。Externally engaged center wheel，Such asNCWType of sun wheel，Is often the weak link in the transmission。Because its engaged with several planetary wheels at the same time，Should be
TBIMethod of mounting ball screw nut：There must be a sleeve with the same diameter as the ball groove of the lead screw，After the silk mother is cleaned with kerosene，Grease the ball tank，Then put a little grease on the head with a needle，Use the grease on the needle to glue the ball one by one into the ball tank，Put the sleeve into the silk masterbatch after discharge，Rotate the screw against the sleeve to screw it in，The function of the sleeve isTBIThe ball screw will not squeeze out the ball when it is screwed in。The following is aboutTBIDetailed steps for installing ball screw nuts：①theTBIBall screw nut and ball are clean。②Put the plastic bead holder(
Simple bearing structure、Internal complexity，Its development needs to consider more than just materials、Manufacturing process and application conditions；It also involves large-scale calculations and analysis，The following Feng Ye mall to talk with youFAGApplication and maintenance methods of angular contact ball bearings。Current，The processing of bearing rings The processing of bearing inner rings and outer rings varies according to the raw materials or blank forms,The process before turning can be divided into the following three types,The whole processing process is：Bar or pipe material（Some bars need to be forged and annealed、normalizing）----Vehicle processing----Heat treatment----grinding----Grinding or polishing----
Gemecon stepper motor has step Angle(It involves the number of phases)、Static torque、And current three elements of composition。Once the three elements are determined，The type of stepper motor is determined。In the selection of Gemecon stepper motor can be selected according to the following steps，This can avoid the trouble caused by improper selection。Specifically as follows，For reference only。1、When choosing the step Angle of the stepper motor, we must pay attention to the parameter that is the ability of load resolution，Convert the load of the system，And then connect the other axes，In this way, the Angle of rotation required by the stepper motor can be obtained，Choose a step Angle thats smaller than this
Analysis of single-phase rectifier circuit diagram of servo driver，From the picture belowl—14(a)Shown is a commonly used single-phase bridge rectifier circuit，It adopts...4A diode converts alternating current into direct current：μIndicates the input AC power supply，When ac voltageμIs positive half cycle time，Its voltage polarity is positive up and negative down，VDl、VD3turn-on，With current flowingRL，The current path is：μA surname→VDl→RL—VD3→μunderweight；When the AC voltage is negative for half a week，Its voltage polarity is negative up and positive down，VD2、VD4turn-on，The current path is：μBelow normal→VD2→RL→vD4→μsuperminus。Work over and over again
The intuitive difference between DC motor and AC motor is：Different external power supply，One is direct current，One is alternating current。Dc motors use direct current as a power source，Ac motors use alternating current as a power source。Electric motor(Electricmotor)，Also known as motor or electric motor，It converts electrical energy into mechanical energy，Mechanical energy can be reused to generate kinetic energy，An electrical device used to drive other devices。Electric machine(Motors)It is a device that converts electrical energy into mechanical energy。It is the use of electrified coils(That is, the stator winding)Generates a rotating magnetic field and closes an aluminum frame for a rotating squirrel cage
As everyone knows，Linear motion guides are used to support and guide moving parts，Make a straight line move in a given direction。Linear motion guides can be divided into sliding friction guides、Rolling friction guide、Elastic friction guide and fluid friction guide。Why is friction inevitable in the operation of linear guide？For IntimePMILinear guide，Fluid lubrication is limited to the boundary area。Friction with metal is inevitable，And energy is lost in the process。Self-lubricating module can not only increase the convenience of user maintenance，And its modular solution allows customers to buy directlyE2Self-lubricating module kit and place it on the slider，IDA
