introduction： Select materials according to the required properties Polymer materials in different applications，Its subjected to a combination of forces and circumstances。Therefore, it is first necessary to understand the conditions of use and their requirements for material properties in detail，Then materials are selected and designed according to performance requirements。However, when selecting materials based on material properties data，Product designers should pay attention，There is a clear difference between plastic and metal，For metals，The performance data can basically be used for material screening and product design，however，Viscoelastic plastics are different，Various test standards and documented polymer properties data are available under many specific conditions，Usually for a short period of time

introduction：Skeleton oil seal is relatively simple，There are usually three parts：Oil seal body、Reinforced skeleton and self-tightening coil springs。The sealing body is divided into the bottom according to different parts、loin、Cutting edge and sealing lip, etc。usual，Skeleton oil seal in the free state，Its inner diameter is smaller than the shaft diameter，That has a certain“Magnitude of interference”。therefore，When the oil seal is loaded into the oil seal seat and shaft，The pressure of the edge of the oil seal and the contraction force of the self-tightening helical spring produce a certain radial tightening force on the shaft，After a period of running，The pressure will quickly decrease or even disappear，consequently，The spring can compensate the self-tightening force of oil seal at any time。 Sealing principle： Due to the oil seal with the shaft

introduction：KOYOThe function of the bearing fit is to make the 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。]The stationary ring and the rotating ring are respectively the stationary part of the installation position(Usually a bearing seat)And rotating part(Usually an axis)Solidify together，Thus, it can transfer the load in the rotating state and limit the position of the moving system relative to the stationary system

introduction： The use of reducer in daily life is very wide，The difference between cycloidal pin wheel and turboworm reducer is as follows； 1、Cycloidal pinwheel reducer is generally a surface output，The void and back gap are very small，Imports can generally be controlled in10Within arc minute。But turbo worms are usually output by shaft。Null return is not easy to control，Especially after a long run-in between the turbine and the worm，There are large empty back。Its usually on a degree scale。 2、Self-locking function is the biggest feature of turbo worm。But the allowable speed range is still very low。And cycloidal needle wheels are usually

introduction：What are the safety guarantees of electric forklifts 1、Leakproof measure （1）Careful disposal of all kinds of padding。Such as oil pan or valve cover，Due to the large contact area，Not easily compacted，Easy to cause oil leakage。Crankshaft rear oil seal leakage，Oil will seep into the clutch，It will not only cost oil but also make the clutch plate stain and slip and burn out。 （2）Tighten each nut according to repair specifications。Oil will seep out of the gasket if it is too loose；Too tight will cause the metal around the screw hole to protrude or the thread to slip, causing oil leakage。Oil pan（case）If the oil drain plug is not tightened or loosened, it falls off，Easy to cause a large loss of oil，
