introduction：Oil seal is used to seal oil（Oil is the most common liquid substance in the transmission system，Also refers to the general meaning of liquid substances）Mechanical element of，It isolates the parts of the transmission parts that need lubrication from the output parts，So the oil doesnt leak。Static seal and dynamic seal（General reciprocating motion）Using a seal is called a seal。The representative form of oil seal isTCOil seal，This is a rubber fully covered double lip oil seal with a self-tightening spring，Generally speaking, the oil seal often refers to thistcSkeleton oil seal。 What is the material of the oil seal？ The oil seal is rubber。The oil seal is mainly used in the joint of two lubricating parts，Prevent oil from seeping out，Like crankshaft

introduction： Length measurement technology that can automatically identify whether the measured length is qualified or not or can automatically sort。Automatic measurement can measure only one parameter﹐It is also possible to measure multiple parameters of a workpiece simultaneously or continuously﹐There are two kinds of active measurement and off-line automatic measurement。Off-line automatic measurement refers to the measurement where the information from the measurement result is not directly used to control the machining﹐For example, with automatic sorters﹑Automatic inspection machines and multi-dimensional inspection devices measure finished workpieces。The automatic sorting machine is used to measure the high accuracy of the fit﹑Need to put the tolerance belt(see

introduction： Abstract: bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]Shell parts require high dimensional accuracy，And visible position tolerance requirements，So after the mold is formed，The dimensional accuracy is achieved by shaping process，At the same time, the end plane of the part meets the requirements of form and position tolerance。Shallow drawing for flange parts，The holder ring is used as a shallow drawing punch
