Electric forklift to riot control Forklifts have been widely used in various sectors of the national economy,Yes harbor、quay、station、Warehouse and industrial and mining enterprises the most basic and main loading and unloading and handling machinery。 In oil、Chemical engineering、Light textile、pharmacy、papermaking、Paint, etc., is flammable、Processing of explosive dangerous goods、Use、Handling and storage industry,Forklifts are also the most widely used,This includes transporting raw materials to the processing site、Transportation of finished products to storage and transportation sites and loading of dangerous goods onto transport vehicles。In these processes,Now and then
Secure a ferrule,The maximum amount of movement of the other ring along the radial or axial direction。The maximum amount of movement along the radial direction is called radial clearance,The maximum amount of movement along the axis is called axial clearance。 Generally speaking,The greater the radial clearance,The axial clearance is also larger,Vice versa。Per 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
Basic principle Vacuum freeze-drying is the principle of sublimation of ice crystals in vacuum state,In a high vacuum,The water in the pre-frozen material is sublimated directly from the ice state to water vapor without melting the ice,Thus drying the material。 Characteristics of vacuum freeze-drying products Ensures protein in food、Vitamins and other nutrients,Therefore, it can maintain the color of the food to the maximum、sweet、taste;Due to low temperature、vacuum、liquidization、Help can effectively prevent the drying process camp cultivation
Reducer is a kind of equipment commonly used in industry。There are many types of common reducer on the market:Planetary reducer、Worm gear reducer is a more common reducer model number。 Worm gear reducer is a compact structure,Large transmission ratio,Transmission machinery with self-locking function。And the structure of turboworm reducer is reasonable、Easy to install、Low operating vibration、Low noise,Energy consumption is also very low,Therefore, it has been more and more widely used in recent years。 However, the worm gear reducer will also fail during use。Reducer heat leakage is a more common one。 Worm gear reduction
Steel used in the manufacture of load-bearing engineering structures﹐Also known as building structural steel。The main requirement for the properties of this type of steel is to have sufficient strength﹐To ensure that there is no permanent deformation and damage during use。In addition﹐This type of steel is often cut during use﹑bend﹑Riveting and welding﹐Therefore, it also requires good formability and weldability。The carbon content of this steel is generally less than0.30%﹐Most of the steel rolled into a certain cross-section shape(Angle steel﹑Steel channel﹑joist﹑Screw thread
1.Gear drive Gear transmission is a kind of mechanical transmission which is widely used,Almost all kinds of machine tools have gear transmission in the transmission device。There are two purposes for using gear transmission device in servo feed system of CNC machine tool。One is to turn the high speed torque of the servo motor(Such as stepper motor、Dc and AC servo motors, etc)The output changes to the input of the actuator with low speed and high torque;The other is to make the moment of inertia of the ball screw and the table have a small proportion in the system。In addition,The required motion accuracy can also be guaranteed for the open-loop system。
Generally speaking,SKFbearing[SKFbearing:SKFThe full name is“Svenska Kullager-Fabriken”The Chinese transliterated name is“SKF”;SKFThe group is headquartered in Gothenburg, Sweden,Is a leader in bearing technology and manufacturing。SKFBearings can be divided into sliding according to different specific structures and similarities and differences in working propertiesSKFBearing and rollingSKFbearing]It heats up after it starts running,Over time,That is, at lower temperatures(Usually warmer than room temperature10~40The degree of)In the normal state。Time to normal,Depending on the bearing size、form、Rotational speed
As early as20Years ago,People have begun to use injection molding technology to achieve two-color injection molding。At the beginning,People didnt realize how far it could go。With the gradual emergence of this technology in reducing secondary processing and reducing raw material costs,Only then did people pay enough attention to it。On account of2CThe system allows different colors、Materials of different hardness or composition are mixed together,Therefore, it can be used in different situations,Such as:Keyboard、toothbrush、Bottle caps、CD boxes and toys, etc。At present,This technology has another very important application,That is, the molding of automobile parts,Such as:Something on the car
The forging process generally consists of the following processes,Immediate blanking、heat、shaping、Post-forging cooling、Pickling and heat treatment after forging。A series of forging defects may occur if the forging process is not proper。 The heating process includes the loading temperature、Heating temperature、Heating rate、Holding time、Furnace gas composition, etc。If not heated properly,For example, the heating temperature is too high and the heating time is too long,Will cause decarbonization、superheating、Overburning and other defects。 For large section size and poor thermal conductivity、Low plasticity stock,If the heat rate is too fast,The holding time is too short,Often make the temperature points
