选择伺服电机变速箱
There are many things to keep in mind when selecting a servo motor gearbox. You should start by knowing the maximum dynamic peak torque of the motor. If you assume the maximum torque will be transmitted to the gearbox, you will end up oversizing and wasting money. Furthermore, a large portion of the motor’s peak acceleration torque is not actually transmitted through the gearbox; rather, it is consumed by the rotor.
A conventional gearbox is typically not very accurate, as up to half of the peak torque is expended in accelerating the rotor and the load. In a servo motor gearbox, the load will be equal to or less than half of the gearbox’s torque rating. You can also determine the amount of backlash by calculating k=motor inertia/load inertia.
Another thing to consider is the frequency of load cycles. Many positioning and motion control applications involve repeated acceleration and deceleration cycles. Additionally, many of these cycles have frequent starts/stops and direction reversals. These cycles create what is known as a “load characteristic cycle.” This cycle can be difficult to predict, but it can be measured and statistically generated for a given servomotor. Then, you’ll be able to make an informed decision about which servo motor gearbox you should buy.
A servo motor gearbox can greatly improve the speed-torque characteristics of a servo motor. For example, planetary gearboxes are a good choice for applications requiring high input speeds. These gearboxes can offer a 10:1 speed reduction, and some high-speed designs can have up to 100:1 ratios. And that’s not all. You can even select a planetary gearbox if you’re worried about noise.
最后,伺服电机变速箱具有广泛的应用可能性。蜗轮蜗杆就是其中一种,它由螺旋螺纹轴和齿轮组成。这种类型的齿轮可用于实现高精度应用,从而消除了对机械部件的需求。除了蜗轮蜗杆传动之外,它还涉及蜗轮在油浴中的摩擦和旋转。然而,蜗轮蜗杆传动机构会因滑动摩擦而产生损耗。不过,多年来,一些制造商已经设法将这些损耗降至最低。
估算伺服电机变速箱最大扭矩主要有两种方法。一种方法是通过齿轮箱测量扭矩。第二种方法是使用摩擦扭矩,该扭矩与电机的峰值扭矩相关。这两种方法都有效,但只有一种方法更适合连续工作应用。这些方法都有其局限性。
最后,伺服电机变速箱有三层。第一层称为速度环,其工作电压与速度成正比。如果速度低于一定水平,它会向电流环发送命令以增加电流。第三层是位置环,它接受来自运动控制器或PLC的命令。这样,三个环路协调运行,为伺服机构提供平稳的运动。
