你知道直线导轨的作用原理吗?

永利总站/ 日期:2018-12-07 发布人:admin

直线导轨可以理解为是一种滚动导引,是由钢珠在滑块跟导轨之间无限滚动循环, 从而使负载平台沿着导轨轻易的高精度线性运动,并将摩擦系数降至平常传统滑动导引的五十分之一,能轻易地达到很高的定位精度。滑块跟导轨间末制单元设计,使线形导轨同时承受上下左右等各方向的负荷,专利的回流系统及精简化的结构设计让的线性导轨有更平顺且低噪音的运动。

Linear guideway can be understood as a rolling guidance, which is infinite rolling cycle of steel balls between slider and guideway, so that the load platform can move along the guideway with high precision and linearity easily, and the friction coefficient can be reduced to one fifth of the normal traditional sliding guidance, which can easily achieve high positioning accuracy. The final unit design between the slider and the guide rail enables the linear guide to withstand loads in both upper and lower directions. The patented reflux system and the simplified structure design allow the linear guide to move smoothly and with low noise.
应用领域:
Application area:
1、直线导轨主要用在自动化机械上比较多,像德国进口的机床,折弯机,激光焊接机等等,当然直线导轨和直线轴是配套用的。
1. Linear guideways are mainly used in automation machinery, such as machine tools imported from Germany, bending machines, laser welding machines and so on. Of course, linear guideways and linear axles are matched.
2、直线导轨主要是用在精度要求比较高的机械结构上,直线导轨的移动元件和固定元件之间不用中间介质,而用滚动钢球。因为滚动钢球适应于高速运动、摩擦系数小、灵敏度高,满足运动部件的工作要求,如机床的刀架,拖板等。如果作用在钢球上的作用力太大,钢球经受预加负荷时间过长,导致支架运动阻力增大。
2. Linear guideways are mainly used in mechanical structures with high precision requirements. Rolling steel balls are used instead of intermediate medium between moving and fixed components of linear guides. Because rolling steel ball is suitable for high-speed movement, small friction coefficient and high sensitivity, it meets the working requirements of moving parts, such as tool holder, trailer, etc. If the force acting on the steel ball is too large, the steel ball will endure the preload for too long, which will lead to the increase of the bracket resistance.
滚珠丝杠使用中出现问题原因分析。丝杠加工时用的轴承有很多种类,也能适应各种用途,很多的设备都可以使用丝杠,滚珠丝杠使用中会出现问题,给大家分析下原因有哪些。
Cause analysis of problems in the use of ball screw. There are many kinds of bearings used in the processing of lead screw, which can also be used for various purposes. Many equipments can use lead screw. There will be problems in the use of ball screw. What are the reasons for this?
 
一、碎裂。
First, fragmentation.
1、丝杠中钢珠破裂,润滑动作温升差异会造成钢珠碎裂。
1. Ball breakage in lead screw and temperature difference of lubrication action will cause ball breakage.
2、丝杠肩部断裂,主要是设计不当,或者丝杠轴颈弯曲。
2. The breakage of the shoulder of the lead screw is mainly due to improper design or bending of the shaft neck of the lead screw.
 
 
二、间隙太大。
Second, the gap is too large.
1、滚珠丝杠扭转位移太大,主要是热处理不当,硬化层太薄,或者硬度分布均匀。
1. Torsional displacement of ball screw is too large, mainly due to improper heat treatment, too thin hardening layer, or even hardness distribution.
2、轴承选用不当,也会造成间隙太大。
2. The improper selection of bearings will also cause too much clearance.
三、钢珠轨道有异物。
3. There are foreign bodies in the steel ball track.
1、有包装材料阻碍了钢珠轨道,或者加工碎屑进入了钢珠轨道。
1. Packaging materials hinder the ball track, or processing debris enters the ball track.
2、螺帽和螺帽做结合不当。
2. Improper combination of nuts and nuts.
3、造成了丝杠的损坏。
3. Damage to the lead screw.
使用滚珠丝杠遇到问题,若是以上三大问题,可根据原因来解决,就可以及时解决问题在加工了,更多精彩内容就继续关注大家吧。
