（1）Synchronous beltPerformance characteristics: 1、The common tooth type on the market isHTD。withCONTItheHTDandSTD You dont have to change the wheel。 2、HTDFor high torque，STDFor high speed。 3、Synchronous sliding operation，Constant speed operation，maintenance-free，Reduced load 4、CTBThe effective tension of the belt is unevenly compressed on the tooth profile。
Triangular beltThere are two kinds of special belt core structure and rope core structure，Respectively by wrapping cloth、Rubber bushing、The tensile body and the substrate are composed of four parts。 The triangle belt with rope core structure is convenient to manufacture，The tensile strength is average，Low price，Widely used The triangular belt with special core structure has good toughness，High strength，Suitable for high speed applications。 Classification introduction： 1、Plain core： Most of the common core with core triangle belt adopts the cord core，A few use cord core。Because these two core structures are fiber twisting or weaving，In the operation of the triangular belt, the fibers shear each other, resulting in the gradual fracture and elongation of the core。therefore，The common triangle belt made of cord core and cord core can only be used in low-load transmission system。
Ac motorIt is a device that converts electrical energy from alternating current into mechanical energy。Ac motor is mainly composed of an electromagnet winding or distributed stator winding to generate a magnetic field and a rotating armature or rotor。An electric motor is made by means of the phenomenon that an energized coil is forced to rotate in a magnetic field。Ac motor is divided into synchronous AC motor and induction motor two kinds。 The stator windings of a three-phase AC motor are basically three separated from each other120Coil of degree，Make triangular or star connections。When a three-phase current is applied，A magnetic field is generated in each coil，These three fields combine to create a rotating magnetic field。
Stepper motor introduction： Stepper motorIt is an open-loop control motor that converts the electrical pulse signal into angular displacement or linear displacement，It is the main executive element in modern digital program control system，Extremely widely used。。In the case of non-overload，Speed of motor、The position of the stop depends only on the frequency and number of pulses of the pulse signal，It is not affected by changes in load，When the stepper driver receives a pulse signal，It drives the stepper motor to rotate a fixed Angle in the set direction，call“Step Angle”，Its rotation is carried out step by step at a fixed Angle。The amount of angular displacement can be controlled by controlling the number of pulses，So as to achieve the purpose of accurate positioning；At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency，Thus to achieve the purpose of speed regulation。 Stepper motor is a kind of induction motor，It works by using electronic circui
Motor with deep groove ball bearings in the process of running，Due to various factors，Artificial is good，Or the error of assembly during installation，The regular maintenance of deep groove ball bearings for motors is not strictly implemented and so on，The load changes periodically or produces abnormal mutations and external causes of damage。When the equipment is in operation for a long time，Bearings wear out, too，Even in peacetime normal bearing maintenance，Bearings wear out, too，But very slowly，After running this way for a long time，When approaching the life of the bearing design，Bearing failure may be caused by normal wear。
At present，PLCThe controller has been widely used in steel at home and abroad、petroleum、Chemical engineering、electricity、Building materials、Machine building、CARS、Light textile、transportation、Environmental protection and cultural and entertainment industries，Usage can be roughly summarized into the following categories。The amount of switching logic controls this isPLCController basics、A wide range of applications，It replaces the traditional relay circuit，Implement logic control、Sequential control，It can be used to control a single device，It can also be used for multi-machine group control and automated assembly line。Such as injection molding machine、Printing press、Stapler machine、Combined machine tool、Grinding machine、Packaging production line、Electroplating line。Analog quantity control in industry
The torque speed sensor is installed between the power drive shaft，It andTR-1Type torque speed power measuring instrument andCZThe type magnetic powder brake is used together，Various engines can be measured、Electric machine、Air blower、compressor、Hydraulic pump、Gear box and other power machinery and transmission machinery0-6000turn/Sub-range of torque speed power。The following small series to introduce you to the role of the torque speed sensor characteristics！
Below you introduce the following knowledge about the classification of intermediate relays！
Fast docking electronic connectors Fast docking electronic connectors（Also commonly referred to as circuit connectors，Electric connector），Bridge two conductors on a circuit,A conductor device that allows a current or signal to flow from one conductor to another。It is widely used in various electrical circuits，The function of connecting or disconnecting currents or signals。The following Xiaobian takes you to understand the definition and manufacturing materials of rapid docking electronic connectors：
Shi Jie electronic connector automation Stone electronic connector，Also called connector，Is used to connect electrical electronic components，Mainly used for power or signal transmission，It is widely used in industry and life。The connector is generally composed of an external connector and an internal terminal。Connectors are generally insulators，Materials like plastic，Split into male ends、Female terminal，The connection is fixed。Terminal as conductor，Transmit signals or power，A lot of them are coated，E.g. tinning、gild/Silver etc.，It acts as a conduction。
