Bearing size classification (1)Miniature bearing——Nominal outer diameter size range is26mmFollowing bearing； (2)Small bearing——Nominal outer diameter size range is28-55mmBearing of； (3)Small and medium bearing——Nominal outer diameter size range is60-115mmBearing of； (4)Medium and large bearing——The male...
Abstract:Various introductions about the reducer…… The reducer is a power transmission mechanism，Speed converters using gears，Switch machine（motor）The number of turns slows down to the desired number of turns，And get a larger torque mechanism。In the mechanism currently used to transmit power and motion，The application range of reducer is quite wide。It can be seen in almost all kinds of mechanical transmission systems，Ships from vehicles、CARS、locomotive，Heavy machinery used in construction，Processing machines and automated production for the machinery industry...
Many customers find that the bearing is damaged，Will be replaced in time，And thought it would cut costs，In fact forNSKImported bearing，If the bearing damage is low，And its easy to fix，At low cost，You can consider repairNSKImported bearing。 1、It should have appropriate viscosity and good viscosity-temperature characteristics。This is trueNSKImported bearings are more important，If the temperature between the machine and the spindle is too high，It is very likely that there will be a change in the situation...

Servo is a closed-loop feedback signal to control position and speed.Servo is widely used in semiconductor equipment,For example, in the gluing machine,Lithography machines and other equipment,The following is about the servo motor related issues have been sorted out,I hope it will be helpful in my future work. 1.Why does the servo motor not lose step？The servo motor driver receives feedback signals from the motor encoder，And compare it with the command pulse，The semi-closed loop control of a position is formed...
Self-aligning roller bearings－Aligning bearing（Bearing load）： Such bearings can only bear radial loads。The diameter is generally not greater than5mmThus the radial structure is compact，Needle roller bearings are fitted with long thin rollers(Roller length is diameter3~10times。Its inner diameter dimensions and load capacity are different from others...
Introduction to deep groove ball bearings with rolling bearing knowledge： After the deep groove ball bearing is installed on the shaft，Bearing within the axial clearance range，The axial displacement of the shaft or housing can be limited in both directions，Therefore, it can be used for axial positioning in both directions。
The cutting machine slide and the copper guide are in contact with each other，And the relative motion under a certain force produces friction，Friction is the opposite of motion，It acts as a barrier to movement。This force excites a body in relative motion to vibrate，It creates friction noise。In addition，There is sliding friction between the slide block and the copper guide rail，Under lubricating conditions without automatic oil supply，Running at high speed for a long time，It is easy to aggravate the wear of the slider，If not adjusted and maintained in time...
Selection principle of electromagnetic relay 1.Selection of power supply used in relay diagram In general，In the circuit design most of the use of direct current...
Because the work flow of security equipment is more complex，The conveying system needs to complete the advance under the actual working condition、recoil、advance、standstill、advance、standstill、A series of movements，However, the existing general conveying system can not accurately realize this series of complex movements。 The mechanical part of the conveying system...
