introduction：LKBearing many modern large construction machinery such as asphalt mixing equipment、Stabilized soil mixing equipment、 The scale of the combined crusher is very large，Each part has a mass of tens to hundreds of tons，And construction machinery is mostly in sand、gravel、Work in harsh environments such as rain and snow，Its technical condition is bound to decline faster than other machinery。

introduction：1.High transmission efficiency In the ball screw pairIn the，The free-rolling ball transfers force and motion between the screw and the nut。This transmission mode replaces the direct action mode between the screw and the nut of the traditional threaded lead screw pair，Therefore, the sliding friction of the traditional lead screw is replaced by minimal rolling friction，The transmission efficiency of ball screw pair is achieved90%above，The driving torque of the entire transmission pair is reduced to that of the sliding screw1/3around，As a result, the heat rate is greatly reduced。 2.High positioning accuracy： Low heating rate of ball screw pair，The temperature rise is small, and the lead screw is pre-stretched and pre-tightened to eliminate axial clearance during processing，The lead screw pair has high positioning accuracy and repeated positioning accuracy。

introduction：Linear displacement sensorIts function is to convert the linear mechanical displacement into an electrical signal。To achieve this effect，The variable resistance slide is usually positioned at a fixed part of the sensor，Different resistance values are measured by the displacement of the slide on the slide rail。The sensor rail is connected to the steady DC voltage，A small current allowed to flow through a microampere，The voltage between the slide and the starting end，Proportional to the length of the slide。Using the sensor as a voltage divider minimizes the need for accuracy in the total resistance of the slide，Because the resistance change caused by the temperature change does not affect the measurement result。 Use requirement： 1、The power supply voltage must be stable： Industrial power requirements±0.1%Stability of，Such as reference voltage10V，Be allowed to±0.01VFluctuation of，Or else，Will cause the display of the trap fluctuation。If the fluctuation amplitude of the display at this time does not exceed t

introduction：samickLinear bearing samickIntroduction to linear bearings： Because the bearing ball is in point contact with the shaft，So the use of small load。The steel ball spins with very little friction resistance，Thus, high precision smooth motion can be obtained。 samickPlastic linear bearing is a self-lubricating linear motion system，The biggest difference between metal linear bearings is that metal linear bearings are rolling friction，There is point contact between the bearing and the cylindrical shaft，So its good for low loads and high speeds；And plastic linear bearings are sliding friction，There is a surface contact between the bearing and the cylindrical shaft，So this is suitable for high load and low speed movement。

introduction：Dingge long stroke slide cylinder can also be called rodless cylinder，Mainly when the travel is longer，The rod cylinder takes up a large installation space，And there is a large deflection，Affect cylinder position accuracy and stability。Therefore, rodless cylinders are often used when the stroke is long，The rodless cylinder has no piston rod sticking out，Its position output is mainly in the form of sliding table。
