FENNERSynchronization belts are widely used,We hear the term synchro band a lot in everyday life,But dont know what a sync belt is?In fact, the synchronous belt is the use of steel wire rope or glass fiber as a strong layer,It is then covered with a circular band of polyurethane or neoprene,The inner circumference of the band is toothed,Make it mesh with the toothed pulley。
I believe you have a certain understanding of relays and circuit breakers,Xiaobian for your defense to see what the difference is?
Regular inspection of ring bearing,It is very important to maintain the full load bearing in good condition,It can also reflect the discovery of problems。Matters and relevant knowledge that should be paid attention to in the use of bearings。It is important to keep the ring bearings lubricated and clean。So when we check the full bearing,The bearing surface should be cleaned first。
Many friends are using machines,When operating,Will notice the sudden vibration of the bearing,I dont know why,Todays short article will give you the answer,takeZHJBearing as an example,Talk about why it vibrates,And how to fix it。
Mechanical guide Mechanical guide,A groove or ridge made of metal or other material,endurable、immobilization、A device that guides a moving device or device and reduces its friction。A longitudinal groove or ridge on the surface of a guide rail,For guidance、Fixed machine parts、Special equipment、apparatus。
Block guide The slider and the guide rail body are a natural pair,No one can work properly without it。Slide rails are troughs or ridges made of metal or other materials,endurable、immobilization、A device that guides a moving device or device and reduces its friction。
Trapezoidal screw The trapezoidal lead screw is used to finish the thread and knurled at one time in the machining process with high efficiency,Low cost,Processing precision requirements are not too high products,Its structural design ideas、The scheme has good value of popularization and application。The following Feng Ye Xiaobian will take you to understand the maintenance of the trapezoid screw:
Screw slide table Screw slide table by bed,skateboard,Lead screw,Transmission composition。Its structure is simple,Easy maintenance。The working principle of the mechanical slide is that the skateboard does longitudinal motion on the bed,Because of its lead screw drive,Add to that the role of the gearbox。Various running speeds can be obtained, such as fast and slow。
STAFLinear slide: Linear rails are ball bearings with rotating motionPrinciple of motion,Clever application in linear motion。 In addition to transmission efficiency, it has the function of guidance,It can not only greatly reduce the friction coefficient than the traditional guidance, but also improve the accuracy of the equipment。 Main application:Numerical control machining machine(CNC)、Injection machine、Robot、Automation equipment、Glue dispenser、Exposure machine、Air original、Semiconductor equipment、Medical equipment and sports equipment… (1)Common rail design: BGX-Non-chain typeBGC-Chain type to reduce inventory Standard type and chain type design common rail-----Easy to upgrade Universal world all kinds of slide size specifications-----Easy to replace Single design is easy to manage
Scroll spline pairIts a linear motion system,When the spline sleeve uses the steel ball in it to move in a straight line on a finely ground spline shaft,Can transmit torque。The spline pair has a relatively compact structure,Can transfer excess load and power,And has a long life。 The ball spline connection is particularly suitable for axial movement of the hub or jacket on the shaft under load,now,Its load carrying capacity is several times higher than that of ordinary splined connections of the same profile size。 The scroll spline is subdivided by the spline shaft、Splined sleeve、The ball bearing and circulating device are composed,There are three of them on the spline shaft120°splined,Both sides of the spline are provided with ball and raceway,Three rows of balls are used to transmit torque forward,The other three rows of balls are used to transfer torque in reverse;When the spline shaft and spline sleeve produce relative linear motion,The ball is rolled in the raceway and reverse circulation device,
