introduction：first、KOYORemoval of bearing periphery Remove the outer ring of the interference fit，Set several outer ring squeeze screw screws on the circumference of the housing in advance，Tighten the screw evenly on one side。Side down。These screw holes are usually covered with blind plugs，Tapered roller bearings and other separate type bearings，Make several notches on the shoulder of the housing catch，This is the time to use gaskets，Then remove with a press or gently pat slowly remove。

introduction：Tapered roller bearingsIt belongs to the separation type bearing，Bearing insides、The outer rings have conical raceways。This type of bearing is divided into a single row according to the number of rows of rollers installed、Double row and four row tapered roller bearings and other different structural types。Single-row tapered roller bearings can withstand radial loads and axial loads in a single direction。When the bearing is under radial load，Theres going to be an axial component，So when you need another bearing that can withstand the axial force in the opposite direction to balance it。

introduction：Steel high temperature resistant linear bearings： Operating temperature at150℃The bearings used above are called high temperature bearings。Due to chromium bearing steel in use temperature exceeds150℃~Cwhen，Its hardness will drop sharply，Dimensional instability，And cause the bearing to not work normally。So for the operating temperature at150℃~E～250℃The bearing works under conditions，If the ring and rolling body are still made of ordinary high-carbon chromium bearing steel，It is necessary to carry out special tempering treatment for bearing parts，Generally, it should be higher than the operating temperature50℃Next to temper。Bearing steel tempered according to the above requirements，It can be used normally at operating temperature。However, the hardness decreased after tempering，Bearing life is reduced。When the bearing operating temperature is higher than250℃when，It must be made of high temperature bearing steel。

introduction：Screw mounting Ball screw by screw、nut、Steel ball、Preforming plate、reverser、Dust filter composition。Its function is to convert rotational motion into linear motion，This is a further extension and development of Acme screw，The significance of this development is to change the bearing from a sliding action to a rolling action。Screw is widely used in the industry，The following Feng Ye Xiaobian will take you to understand its installation。

introduction：Do not hammer bearing end face and non-force surface directly after installation，Should be pressed block、Sleeve or other device tool equalizes the load on the bearing，Do not transfer power through the rolling body。If the exterior of the device is coated with lubricating oil，Will make the installation smoother。If the fit interference is larger，The bearing should be heated in mineral oil until80~90℃Post haste device，Strict control of oil temperature does not exceed100℃，To avoid tempering effect hardness reduction and impact size recovery。In case of disassembly difficulties，It is recommended that you use the removal tool to pull outward while carefully pouring hot oil on the inner ring，Heat will shrink the bearing inner ring，Thus making it easier to fall apart。

introduction：Extruder screw type There are many types of extruder screw models，Mainly depends on the type of extruder equipment and decide the screw type。Screw extruder is mainly used to extrude soft、Hard polyvinyl chloride、Polyethylene and other thermoplastics，Can process a variety of plastic products，Like blowing film、Tube extrusion、Clamp plate、Drawstring, etc，Can also be used for melt granulation。 So what are the screw models commonly used in extruders?The following Feng Ye Xiaobian will take you to understand the list of several commonly used models of extruder screws。
