滚珠丝杠和直线电机的区别

来源:http://www.jngongrun.com/ 日期:2020-11-20 发布人:admin

线性电动机,也称为线性电动机,是制造公司在各个领域中常用的一种机械设备。 通过将其安装在生产设备上,可以为企业的生产线提供高速自动直线运动,可以有效地提高企业的生产能力。 作为产品,直线电机具有许多优势  以下是导轨丝杠和直线电机的主要特征之间的一些比较:
Linear motor, also known as linear motor, is a kind of mechanical equipment commonly used by manufacturing companies in various fields. By installing it on the production equipment, it can provide high-speed automatic linear motion for the production line of the enterprise, and can effectively improve the production capacity of the enterprise. As a product, linear motor has many advantages. The following are some comparisons between the main features of guide screw and linear motor:
1,速度
1. Speed
直线电动机在速度方面具有相当大的优势。 直线电机的速度为300m / min; 加速度是10克。 滚珠丝杠的速度为120 m / min,加速度为1.5 g。 线性电动机与速度和加速度相比具有相当大的优势,并且在成功解决热量问题之后线性电动机的速度进一步提高,并且“旋转伺服电动机滚珠丝杠”在速度上更加困难。 然后改善。 从动态响应来看,线性电动机由于诸如运动惯性和游隙以及机构复杂性之类的问题而具有绝对优势。
Linear motor has a considerable advantage in speed. The speed of the linear motor is 300m / min and the acceleration is 10g. The speed of the ball screw is 120 m / min and the acceleration is 1.5 G. Compared with speed and acceleration, linear motor has a considerable advantage, and after successfully solving the heat problem, the speed of linear motor is further improved, and the speed of "rotary servo motor ball screw" is more difficult. And then improve. From the dynamic response point of view, the linear motor has the absolute superiority because of the problems such as the motion inertia and clearance and the complexity of the mechanism.
在速度控制方面,直线电机响应速度更快,速度范围更广, 高可达1:10000,可以在瞬间开始时达到 大速度,并且可以快速停止。
In terms of speed control, the linear motor has faster response speed, wider speed range, up to 1:10000, and can achieve high speed at the instant start, and can stop quickly.

2,精度
2. Accuracy
在精度方面,由于传动机构的原因,线性电动机的插补磁滞简单降低。 通过位置检测反馈控制,定位精度,再现精度和绝对精度高于“旋转伺服电机滚珠丝杠”,并且易于实现。
In terms of accuracy, the interpolation hysteresis of linear motor is reduced simply because of the transmission mechanism. Through the position detection feedback control, the positioning accuracy, reproduction accuracy and absolute accuracy are higher than "rotary servo motor ball screw", and are easy to realize.

滚珠丝杠
直线电机的定位精度可以达到0.1μm。 “旋转伺服电机滚珠丝杠”的精度为2〜5μm。
The positioning accuracy of linear motor can reach 0.1 μ M. The accuracy of the ball screw of the rotary servo motor is 2 ~ 5 μ M.
3,能耗
3. Energy consumption
“旋转伺服电机滚珠丝杠”是一种节能的增压器传动装置。 当提供相同的转矩时,线性电动机消耗的能量大约是“旋转伺服电动机滚珠丝杠”的两倍。 此外,线性电动机的可靠性受控制系统的稳定性的影响,并且对周围环境具有很大的影响。 因此,必须采取有效的磁隔离和保护措施,以阻止磁场对滚动导轨的影响和切削粉尘的吸附。
Rotary servo motor ball screw is a kind of energy-saving supercharger transmission device. When the same torque is provided, the energy consumption of linear motor is about twice that of "rotary servo motor ball screw". In addition, the reliability of the linear motor is affected by the stability of the control system, and has a great impact on the surrounding environment. Therefore, effective magnetic isolation and protection measures must be taken to prevent the influence of magnetic field on rolling guide and adsorption of cutting dust.

4,噪音
4. Noise
线性电动机的噪音低,这是因为线性电动机不受离心力的约束,在运动过程中没有机械接触,也没有摩擦和噪声。 传动部件不磨损,可以大大减少机械损耗,避免拖缆,电缆,齿轮,皮带轮产生的噪音,从而提高了整体效率;
The noise of linear motor is low, because the linear motor is not constrained by centrifugal force, there is no mechanical contact, friction and noise in the process of motion. The transmission parts are not worn, which can greatly reduce the mechanical loss and avoid the noise generated by the streamer, cable, gear and pulley, so as to improve the overall efficiency;
长时间使用后,滚珠丝杠已在滚珠表面上脱落,或者滚珠丝杠轴存在切割受力面的问题,这间接影响了滚珠的运行轨迹,从而导致滚珠之间的摩擦。 螺母和轴会引起振动。 这样噪音太大了;
After a long time of use, the ball screw has fallen off on the surface of the ball, or the ball screw shaft has the problem of cutting the force surface, which indirectly affects the running track of the ball, resulting in friction between the balls. Nuts and shafts can cause vibration. It's too noisy;
5,行程
5. Itinerary
直线电机理论上可以实现无限行程;
In theory, linear motor can realize infinite travel;
导轨丝杠的螺母运行到有效行程后,仍可以正确旋转,但在正常情况下,不能过度旋转,否则会损坏滚珠丝杠,导致大量的滚珠颗粒和螺母掉落 关。 通常不建议在运行时继续操作。
After the nut of guide screw runs to the effective stroke, it can still rotate correctly. However, under normal conditions, excessive rotation is not allowed. Otherwise, the ball screw will be damaged and a large number of ball particles and nuts will fall off. It is generally not recommended to continue at run time.
