Industrial beltstore: 1. Belts and wheels should be kept clean Must not be stained with oil and water。 2. Belt installation,The transmission system should be checked,Whether the drive shaft is perpendicular to the drive wheel,Whether the drive shafts are parallel to each other,Whether the drive wheel is on a flat surface,If not,Should be corrected。 3. Do not stain the belt with grease or other chemicals。 4. Do not apply tools or external forces directly to the belt during belt installation。 5. The temperature range of the belt is:-40°-120°C 。

There are two main reasons for synchronous belt deviation: one、Yes sync beltIn itself: The synchronization belt runs for a long time,The tension of the synchronous belt core decreases continuously,Then the synchronization belt aging and left and right tension inconsistency。In this case,You can replace the synchronization belt;If the internal and external synchronous belt tension is inconsistent,The position of the internal and external synchronization belt can be changed,When the deviation is not very serious,Under the auxiliary action of guide wheel and tensioning wheel stop ring,Can solve the problem。 two、Is the cause of the guide wheel or tension wheel: When the synchronization belt runs off,The direction of the deviation is to run where the height。 The machine has been working for a long time,Under the action of synchronous belt tension,It should be said that the guide wheel and the tension wheel have different degrees of wear,There is even deformation of the guide wheel and tension wheel(Inw
Screw picture The screw, collectively referred to as the ball screw, converts the rotary motion into linear motion,Or the ideal product for converting linear motion into rotary motion。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。Xiaobian prepared some screw pictures,The following Xiaobian will take you to have a look! Screw picture:
Dingge sliding table accessories Dingge sliding table is a mechanical structure that can provide linear motion,Can be used horizontally or vertically,It can also be used in combination with specific motion mechanisms,Commonly referred to in the automation industryXYshaft、XYZAxis and other multi-axial motion mechanism。The widely used Dingge sliding table can be divided into two types:Synchronous belt type and ball screw type。The following Feng Yes small edition will take you to understand the accessories of these two slides。 Sliding table fittings: Synchronous belt type linear sliding table is mainly composed of: belt、Linear guide、Aluminium alloy profile、coupling、motor、Photoelectric switch。 Ball screw type linear sliding table is mainly composed of: Ball screw、Linear guide、Aluminium alloy profile、Ball screw support seat、coupling、motor、Photoelectric switch。
Gear motorRefers to the reducer and motor(motor)Ensemble of。This integration is also commonly referred to as a geared motor or a geared motor。Usually by a professional reducer production factory,After integration and assembly,With motor integrated complete supply。 Speed regulation method of decelerating motor: Gear motor is a fixed speed motor,Once the speed ratio is selected,Motor selection,The rear output speed is fixed。But in actual use,There are also many occasions where variations in speed are required,Such as the spindle speed of the lathe、Shaft speed of various agitators、Conveyor speed when transporting different items, etc,How to speed control is a topic that engineers and technicians are very concerned about。The following is a brief description of various speed regulation methods applied in the current project。 1.Variable pole speed regulation is a simple and economical method of speed regulation。But only small and medium capacity(2kwbelow)And start a few occasions。Usually only two speeds,The sp
Permanent magnet synchronous motorHave simple structure,Small size、High efficiency、High power factor advantage。At present,Permanent magnet synchronous motors are already in the metallurgical industry(Ironworks and sintering plants, etc)、Ceramic industry(Ball mill)、Rubber industry(Internal mixer)、Oil industry(Pumping unit)、Textile industry(Double twister、Spinning frame)And other industries、Low voltage motor in the performance,And gradually accumulate design and operation experience。 So heres the question,Is the permanent magnet synchronous motor a DC motor?But for,So what category does it fall into? 1、Permanent magnet synchronous motor is not DC motor; 2、“Permanent magnet synchronous linear motor”Its AC motor.,Because whether it is used as a generator or an electric motor,The current in its stator windings is AC,And its moving son(oscillator)There are permanent magnets on it,The required winding also has no current。 (1)“Permanent magnet”Refers to the rotor of the motor(Counter rotating machine)Or actor(Linear
