Panasonic programmable controller With the development of technology,Programmable controller also became programmable controller for shortPCorPLCIt is an electronic system for numerical operation,Specifically designed for use in industrial environments。It uses a memory that can be programmed,Used to store logical operations and sequence control during execution、timing、Instructions for counting and arithmetic operations,And through digital or analog input(I)Sum output(O)port,Control various types of machinery or production processes。 Panasonic programmable controller installation:
Overview of programmable controllers Early programmable controllers were called programmable logic controllers(Programmable Logic Controller),For shortPLC,It is mainly used to replace the relay to achieve logic control。With the development of technology,The function of this device has greatly exceeded the scope of logical control,therefore,Today such devices are called programmable controllers,For shortPC。But to avoid it with a personal computer(Personal Computer)Short for confusion,So the programmable controller for shortPLC。
JTROil-free liner linear bearing Oil-free liner linear bearing is a linear motion system,Used in combination with linear travel and cylindrical shaft。Due to the bearing ball contact with the bearing jacket point,The steel ball rolls with minimal friction resistance,Therefore, linear bearings have low friction,And relatively stable,Does not vary with bearing speed,Can obtain high sensitivity、Smooth linear motion with high accuracy。Linear bearing consumption also has its limitations,The most important is that the bearing impact load capacity is poor,And the carrying capacity is also poor,Secondly, the vibration and noise of linear bearings are larger when moving at high speed。The automatic selection of linear bearing is included。Linear bearings are widely used in precision machine tools、Textile machinery、Food packaging machinery、Sliding parts of industrial machinery such as printing machinery。
JTRHigh temperature linear bearing High temperature resistant linear bearings:First and foremost is the ability to withstand the heat。There are many kinds of high temperature bearing,According to different needs,Different environment,Different types of bearings can be installed。
fagDeep groove ball bearing dimensions In the field of automation,fagDeep groove ball bearings have always been key products,It has become a variety of machine tools、CNC machining center、CARS、An indispensable and important functional component in precision electronic machinery。Believe that more people prefer to look at pictures than words,The following Xiaobian will take you to have a lookfagDeep groove ball bearing size drawing bar!
fagDeep groove ball bearing picture FAGDeep groove ball bearing brand belongs to the German Schaeffler Group(SCHEAFFLER)subordinate,The Group is a global leader in the production of rolling bearings and linear motion products,It is also one of the most reputable suppliers in the automotive industry。With the development of The Times,Bearings have become one of the indispensable parts of the automation industry,The following Xiaobian will take you to have a look!
1、Plain bearing: Plain bearings have no inner and outer rings and no rolling body,It is generally made of wear-resistant materials。Often used at low speeds,Light load and fill lubricating oil and maintain difficult mechanical rotation parts。 2、Knuckle bearing: Knuckle bearingThe sliding contact surface is spherical,Mainly suitable for oscillating motion、Tilt motion and rotation motion。 3、Rolling bearing: Rolling bearings are divided into centripetal bearings and thrust bearings according to the load direction or nominal contact Angle they can withstand。The radial contact bearing has a nominal contact Angle of0The centripetal bearing,The nominal contact Angle of the radial angular contact bearing is greater than0to45The centripetal bearing。The axial contact bearing has a nominal contact Angle of90Thrust bearing,Thrust angular contact bearings have nominal contact angles greater than45But less than90Thrust bearing。
