The ball screw, sensor, motor, software and hardware of the electronic universal testing machine, the transmission system is an important part of the testing machine, how to choose a high-quality testing machine from many enterprises, these five factors play a decisive role.
1. Ball Screw: The lead screw currently used in the electronic universal testing machine has a ball screw and a lead screw. In general, the trapezoidal screw has a large gap, a large friction force and a short service life. At present, there will be some manufacturers on the market. In order to save more cost, a trapezoidal screw will be used instead of a ball screw.
2. Sensor : The sensor is an important component of the accuracy and force stability of the testing machine. Currently, the types of electronic universal testing machine sensors on the market are S-type and spoke-type. The internal resistance strain gauge of the sensor is not high, and the anti-aging ability of the rubber for fixing the strain gauge is not good, and the material of the sensor is not good, which will affect the accuracy of the sensor.
3. Motor : High-quality electronic universal testing machine motor adopts AC servo speed control system, Panasonic AC servo motor, stable and reliable performance, with protection devices such as overcurrent, overvoltage and overload. At present, there is also an electronic universal testing machine on the market that uses ordinary three-phase motor or variable frequency motor. This kind of motor adopts analog signal control, the control reaction is slow, the positioning is inaccurate, and the general speed regulation range is narrow, and there is no low speed or low speed. There is no high speed and the speed control is not accurate.
4. Software and hardware: The high-quality electronic universal testing machine adopts brand computer, and the control system software is Windows XP operating system platform. It has the characteristics of fast running speed, gentle interface and simple operation, which can meet the test and measurement needs of different materials. Standard, international or industry standards measure the physical properties of various materials.
V. Transmission system: There are two main types of transmission parts of the electronic universal testing machine. One is the arc synchronous gear belt and the precision screw shaft transmission; the other is the ordinary belt transmission. The first transmission mode has stable transmission, low noise, high transmission efficiency, high precision and long service life. The second transmission method can not guarantee the synchronization of the transmission, so the accuracy and stability are not as good as the first transmission system.
