直线导轨跟圆导轨有什么区别吗?

来源:http://www.jngongrun.com/ 日期:2020-09-14 发布人:admin

直线导轨跟圆导轨都是我们身边很重要的机械配件,那么大家知道它们两个有什么区别吗?今天我们就一起来了解一下吧!

Linear guide rail and circular guide rail are very important mechanical parts around us. Do you know the difference between them? Let's learn about it today!
这主要从外观上区别,圆轨从外观上看是圆形的,直线导轨又称方轨,外观上是长方体的。
This is mainly different from the appearance. The circular rail is circular in appearance, and the linear guide rail is also called square rail, which is cuboid in appearance.
1、直线导轨产品特点定位精度高,重现性佳直线导轨的滚动运动方式,摩擦系数比较小,静摩擦力与动摩擦力的差距很小,即使在进给时也不会有空转打滑的现象,解析能力与重现性较好,因此可以实现木工雕刻机可长时间维持精度直线导轨的滚动摩擦力μm级的定位精度。低摩擦阻力。润滑容易,可减小至滑动导轨摩擦阻力的1/20~1/40润滑结构简单。摩擦接触面的磨耗降底,滑作用优良。因此可以长时间维持行走精度。
1. Linear guideway is characterized by high positioning accuracy and good reproducibility. The rolling motion mode of linear guide has small friction coefficient, and the difference between static friction and dynamic friction force is very small. Even when feeding, there will be no idling and slipping phenomenon. The analytical ability and reproducibility are good. Therefore, it can realize the determination of μ m level of rolling friction force of linear guide for woodworking engraving machine to maintain precision for a long time Bit accuracy. Low friction resistance. It is easy to lubricate and can be reduced to 1 / 20 ~ 1 / 40 of the friction resistance of the sliding guide rail, and the lubrication structure is simple. The wear of the friction contact surface is reduced to the bottom and the sliding effect is excellent. Therefore, the walking accuracy can be maintained for a long time.
2、从摩擦、可承受载负荷考虑,方规就是方型直线导轨是面接触式摩擦,摩擦力较大,负载均匀,需要经常上油润滑但圆形导轨就是圆柱形的线型导轨,摩擦小,由于是一系列滚珠的点接触,需要支撑的地方有限,刚性差,负载性能有限,载径向有较好承载力,轴向承载比较小。而且方形轨道高速,阻力小。
2. Considering the friction and load bearing capacity, the square gauge is a square linear guide rail, which has large friction force and uniform load, and needs to be lubricated frequently. However, the circular guide rail is a cylindrical linear guide rail with small friction. Due to the point contact of a series of ball bearings, the supporting place is limited, the rigidity is poor, the load performance is limited, and the radial load bearing capacity is good The bearing capacity is relatively small. And it's a little square high-speed track.
上面这些就是直线导轨与圆导轨之间的区别,是不是很容易区分呢?相信你们已经学会了!如有更多的疑问可以关注公司网站:http://www.jngongrun.com会有在线客服为您进行解答!
