滚珠丝杠是精密机械上最常使用的传动元件,其主要功能是将旋转运动转换成线性运动,或将扭矩转换成轴向反覆作用力,同时兼具高精度、可逆性和高效率的特点。
Ball screw is the most commonly used transmission element in precision machinery. Its main function is to convert rotary motion into linear motion or torque into axial repetitive force. It also has the characteristics of high precision, reversibility and high efficiency.
3、传感器
3. Sensors
传感器是拉力机的精度和测力稳定性的重要部件,目前市场上的拉力机传感器的类型有S型、轮輻式。传感器内部电阻应变片精度不高、固定应变片用的胶抗老化能力不好、传感器的材料不好都会影响传感器的精度。
Sensor is an important part of the precision and measuring stability of the pulling machine. At present, the types of pulling machine sensors on the market are S-type and spoke-type. The accuracy of the sensor is affected by the inaccuracy of the resistance strain gauge inside the sensor, the bad anti-aging ability of the adhesive used for fixing the strain gauge and the bad material of the sensor.
4、传动系统
4. Transmission system
拉力机一般使用同步带传动,同步带传动能吸振,噪音小,传动平稳,效率高,结构紧凑,适宜于多轴传动,不需润滑,无污染,因此可在不允许有污染和工作环境较为恶劣的场所下正常工作。
Tension machine generally uses synchronous belt transmission, synchronous belt transmission can absorb vibration, low noise, smooth transmission, high efficiency, compact structure, suitable for multi-axis transmission, no lubrication, no pollution, so it can not allow pollution and work in a worse environment under the normal work.
5、电机
5. Motor
优质拉力机的电机采用交流伺服调速系统,性能稳定可靠,具有过流、过压、过载等保护装置。
The motor of high quality pulling machine adopts AC servo speed control system, which is stable and reliable, and has protection devices such as over-current, over-voltage and over-load.
