你知道滚珠丝杆是怎么样循环的吗?

永利总站/ 日期:2018-12-25 发布人:admin

滚珠是滚珠丝杆上面的重要部件,但其做循环运动的过程中,滚珠和丝杠之间的触摸有的是会脱离的,有的则会一直保持触摸状况。根据滚珠和丝杠的触摸状况的循环方法咱们可以将其分为外循环和内循环两种,前者是会脱离的,而后者是不会脱离的。下面就为咱们重点先容一下这两种循环方法:

Ball is an important part on the ball screw, but in the process of its circular motion, the touch between ball and screw will be detached, and some will keep the touch condition all the time. According to the circular method of the contact condition of ball and lead screw, we can divide it into two kinds: external circulation and internal circulation. The former can be detached, while the latter can not be detached. Now let's focus on these two methods:
一、外循环
First, external circulation
在外循环中,滚珠丝杆螺母的返回方法是有差异的,现在主要有三种,即螺旋槽式、插管式和端盖式。
In the external circulation, the return methods of ball screw nuts are different. Now there are three main types: spiral groove type, intubation type and end cover type.
1、端盖式
1. End Cover Type
从外观上就可以看得出来,它的螺母上面能够明晰地看到一个纵向孔,这是让滚珠丝杆里边的滚珠能够顺利地回到原来的位置。而在盖板上面则会开上一个口儿,是作为滚珠回程之用的。滚珠就是在两种措施的协助下实现的循环。
It can be seen from the appearance that a longitudinal hole can be clearly seen on the nut, which enables the ball inside the ball screw to return to its original position smoothly. On the top of the cover, there will be a slit, which is used for the return of balls. Ball is a cycle achieved with the assistance of two measures.

2、插管式
2. Intubation type
望文生义必定离不开管子的运用,而且运用的是弯形的管子,这种设计工艺能够安定地确保滚准回程,但是关于这种类型的滚珠丝杆咱们要注意的是一定要加大弯管的径向直径,这样才干确保它露在螺母外面。
Wangwenshengyi must be inseparable from the use of pipes, and the use of curved pipes, this design process can ensure stable roll back, but for this type of ball screw we must pay attention to increase the radial diameter of the elbow, so as to ensure that it is exposed outside the nut.
3、螺旋槽式
3. Spiral groove
螺旋槽式的螺母外面用铣床铣出了一个螺旋槽,所以很简单从外观辨认出。
A spiral groove is milled on the outside of the spiral groove nut, so it can be easily recognized from the outside.
第二、内循环
Second, internal circulation
在内循环滚珠丝杆里边反向器的运用是十分要害的,它是确保滚珠能够实现循环的前提条件,平常咱们触摸到反向器主要有两种类型,即圆柱凸键式和扁圆镶块式。
It is very important to use the reverse device inside the inner circle ball screw. It is the precondition to ensure that the ball can realize the cycle. Usually we touch the reverse device mainly has two types: cylindrical convex key type and flat circular insert type.
