Speed regulating motor is used to change the motorSeries of、voltage、Electric current、Frequency and other methods to change the speed of the motor,A motor designed to achieve high performance。 Due to its excellent performance,Speed regulating motors have been widely used in steel、Power station、cable、Chemical engineering、petroleum、water mud、spin、Printing and dyeing、papermaking、Machinery and other industrial departments for constant torque or decreasing torque load machinery stepless speed regulation with,Especially suitable for pump and fan load support with large flow changes,Good energy saving effect can be obtained。
40Since the emergence of the synchronous belt,Because of its unique advantages, it is widely used in modern machinery industry.After more than half a century of development,The synchronous belt has been developed from a single trapezoidal tooth to a circular arc tooth、Semi-circular tooth、Parabolic teeth in many forms.The material has also developed from neoprene to rubber and polyurethane. Structure of the synchronization belt:The synchronization belt consists of a tensile core、Filled with rubber and toothed bread cloth.
Permanent magnet synchronous motor can install the motor as a whole on the axle,Form an integral direct drive system,That is, a wheel shaft is a driving unit,A gearbox is eliminated。Permanent magnet synchronous motorThere are mainly the following characteristics: (1)PMSMHigh power efficiency and high power factor; (2)PMSMLow fever,Therefore, the structure of the motor cooling system is simple、Small size、Low noise; (3)The system adopts completely closed structure,No transmission gear wear、No transmission gear noise,Free lubricating oil、maintenance-free; (4)PMSMThe allowed overload current is large,Significantly improved reliability; (5)The whole transmission system is light weight,The unsprung weight is also lighter than the traditional wheel and shaft drive,High power per unit weight; (6)Since there is no gearbox,The bogie system can be designed at will:Such as a flexible bogie、Single axle bogie,The power performance of the train is greatly improved。
We can use a sounder,Check the size and sound quality of the rolling sound of the machine tool bearing in operation。Because the machine tool bearing even if there is a slight peel and other damage,Abnormal and irregular sounds can also be produced,So it can be distinguished with a sounder,Play a preventive role in advance。
Linear rolling guides are available in a variety of lengths,Such assktrail。Usually the length of the guide rails supplied by each manufacturer is not the same,But the long guide rail is generally3~4m。Longer guides are supplied in sections,Two or more short guides can be joined to form long guides,Thus to ensure that the parts can produce a large displacement,To suit the needs of various trips and uses。
Cross guide A cross rail is a groove or ridge made of metal or other materials,endurable、immobilization、A device that guides a moving device or device and reduces its friction。A longitudinal groove or ridge on the surface of a guide rail,For guidance、Fixed machine parts、Special equipment、apparatus。Guide rail is also called slide rail、Linear guide、Linear slide,Used for linear reciprocating motion,Has a higher load rating than linear bearings, At the same time can bear a certain torque,High precision linear motion can be achieved under high loads。Guide rail is mainly divided into two categories: roller guide rail and ball guide rail。
Guide brand A rail is a groove or ridge made of metal or other material,endurable、immobilization、A device that guides a moving device or device and reduces its friction。A longitudinal groove or ridge on the surface of a guide rail,For guidance、Fixed machine parts、Special equipment、apparatus。Guide rail is also called slide rail、Linear guide、Linear slide,Used for linear reciprocating motion,Has a higher load rating than linear bearings, At the same time can bear a certain torque,High precision linear motion can be achieved under high loads。With the development of automation industry,The guide rail has always been a key product,With the increasing range of guide rail applications,There are a lot more brands,The following Xiaobian will take you to understand。
Silver ball screw on The upper silver ball screw is to convert the rotary motion into a straight line motion,Or the ideal product for converting linear motion into rotary motion。On the silver ball screw by the screw、Nut and ball。Its function is to convert rotational motion into linear motion,This is a further extension and development of ball screws,The significance of this development is to change the bearing from a rolling action to a sliding action。
Threading rod Threaded rod is a transmission element commonly used in tool machinery and precision machinery,Its main function is to convert rotational motion into linear motion,Or convert torque into axial repeated force,High precision at the same time、Reversibility and rate characteristics。Because it has very little friction resistance,Ball screws are widely used in various industrial equipment and precision instruments。
Blacksmith support seat dealer The blacksmith support is the bearing that connects the lead screw to the motor,Construction with special features on the finished shaft end of standard ball screw stock,Standardized support units are preparedEK、EFtype,A standard support unit is prepared for the general ball screwBK、BFtype。If you want to buy genuine blacksmith support you can go to the Fengye mall to buy,Because all the support seats they bought were original and authentic。
