滚珠丝杆是工具机械和精密机械上常使用的传动元件，是由螺杆、螺母、钢球、预压片、反向器、防尘器组成。下面导轨丝杠厂家来讲讲滚珠丝杆的特性。

Ball screw is a transmission element commonly used in tool machinery and precision machinery. It is composed of screw, nut, steel ball, pre-press, reverser and dust protector. Next, the guide screw manufacturer will talk about the characteristics of the ball screw.

1、与滑动丝杆副相比驱动力矩为1/3

1. Compared with sliding screw pair, the driving torque is 1/3

由于滚珠丝杆副的丝杆轴与丝母之间有很多滚珠在做滚动运动,所以能得到较高的运动效率.与过去的滑动丝杆副相比驱动力矩达到1/3以下,即达到同样运动结果所需的动力为使用滚动丝杆副的1/3.在省电方面很有帮助。

Since there are many balls rolling between the screw rod shaft and the screw nut of the ball screw pair, it can obtain higher movement efficiency. Compared with the sliding screw rod pair in the past, the driving torque is less than 1/3, that is, the power required to achieve the same movement result is 1/3 of that of using the rolling screw rod pair. It is very helpful in saving electricity.

2、高精度的保证

2. Guarantee of high accuracy

滚珠丝杆副是用世界高水平的机械设备连贯生产出来的,特别是在研削、组装、检查各工序的工厂环境方面,对温度·湿度进行了严格的控制,由于完善的品质管理体制使精度得以充分保证.

The ball screw pair is continuously produced by the world's high-level mechanical equipment. Especially in the aspects of grinding, assembly and inspection of the factory environment of each process, the temperature and humidity are strictly controlled. Due to the perfect quality management system, the accuracy is fully guaranteed

3、微进给可能

3. Microfeed possible

滚珠丝杆副由于是利用滚珠运动,所以启动力矩小,不会出现滑动运动那样的爬行现象,能保证实现精确的微进给.

Because the ball screw pair uses ball motion, the starting torque is small, and there will be no creeping phenomenon like sliding motion, which can ensure accurate micro-feeding

4、无侧隙、刚性高

4. No side clearance, high rigidity

滚珠丝杆副可以加予压,由于予压力可使轴向间隙达到负值,进而得到较高的刚性(滚珠丝杆内通过给滚珠加予压力,在实际用于机械装置等时,由于滚珠的斥力可使丝母部的刚性增强).

The ball screw pair can be preloaded, because the preload can make the axial clearance reach a negative value, thus obtaining a higher rigidity (when the ball screw pair is actually used in mechanical devices, the repulsive force of the ball can enhance the rigidity of the screw head)

5、高速进给可能

5. High speed feed possible

滚珠丝杆由于运动效率高、发热小、所以可实现高速进给(运动)。

The ball screw can realize high-speed feed (movement) due to its high movement efficiency and low heat.

此外滚珠丝杆润滑时，因为丝杆螺帽里面的钢珠有一定的间隙。加太多油反有一定影响。润滑时，可以把螺帽转下来之后用棉签或者其它清理一下里面的脏东西就可以了。更多相关内容就来我们网站http://www.jngongrun.com咨询吧！

In addition, when the ball screw is lubricated, there is a certain gap between the steel balls in the screw cap. Adding too much oil has a certain impact. When lubricating, you can turn the nut down and use a cotton swab or other tools to clean the dirt inside. Come to our website for more relevant content http://www.jngongrun.com Ask!
