introduction：The installation of diagonal contact ball bearings is more complicated than that of deep groove ball bearings，Most are installed in pairs，And need to use preloading load。well-installed，Can make the working accuracy of the host、Bearing life is greatly improved；Or else，Not only the accuracy is not up to the requirements，Longevity is also affected。

introduction：The bearing accuracy of the main shaft still cannot meet the requirements，After thickening the journal and making raceway on it to replace the inner ring，And the steel ball was measured，Set of three in size，Each set of steel balls is taken close120°The interval of separation，Due to the reduction of a heavy machined surface，One less mating surface，At the same time, the stiffness of shaft-bearing system is improved，The three - and three-grain steel balls are equally spaced，It also improves the rotation accuracy of the shaft，Therefore, the accuracy requirements of the instrument are met。

introduction：The bearing with seat can automatically adjust the installation error easily and effectively，It can be easily installed on various industrial shafts，It is especially useful in the rack of equipment。Bearing seat product range is very wide，There are vertical seats on the type、Various flanged seats、With keyway seat、Round seat，Grey cast iron holder is used on the material、Ductile iron base、Steel plate stamping seat、Stainless steel and plastic seats, etc，So what are the characteristics and advantages of the outer spherical bearing with seat？ one、Outer spherical bearing with seat is composed of outer spherical bearing and bearing seat，It is not necessary to design the bearing box separately when in use，Small size，Simple structure，It can be directly bolted on the design part of the main engine，Easy to use。 two、Simple and practical Bearing seat for the overall structure，Large carrying capacity，Good rigidity，Bearings and housings are interchangeable，That is, the same bearing seat can be installed with different types

introduction：Couplings are used to join two axes in different mechanisms（Drive shaft and driven shaft）A mechanical part that rotates together to transmit torque。The two axes cannot be separated when the machine is running，Only after the machine parks and disassembles the connection，The two axes can be separated。In high-speed and heavy-duty power transmission，Some couplings have cushioning、Damping and improving the dynamic performance of shafting。The coupling consists of two halves，Respectively connected with the drive shaft and the driven shaft。The general engine is mostly connected with the working machine by means of a coupling。

introduction：The ball screw nut pair is a rotating motion driven by the feed motor，Translated into a straight line movement of the tool rest or table。A curved spiral groove is machined on the lead screw and nut，They form spiral raceways when fitted together，And install the ball in the raceway。When the lead screw is rotated relative to the nut，Then the nut produces axial displacement，And the ball rolls along the raceway。The ends of the spiral groove of the nut are connected with a bead returner，So that the ball can cycle again and again，The two ends of the pipe also play the role of bead，In case the ball falls off the raceway。
