导轨的结构与特长

The structure and advantages of the guide rail
钢球沿着LM轨道和LM滑块上经精密研磨加工而成的4列滚动面进行滚动;通过球保持器与组装在LM滑块上的回球器,使钢球列作循环运动。
The steel ball rolls along the LM track and LM slider, which are precision ground and processed into four rows of rolling surfaces; By using the ball holder and the ball return device assembled on the LM slider, the steel ball column moves in a circular motion.
为使LM滑块上的4个作用方向(径向反径向和侧向)均具有相同的额定载荷,各钢球列被设计成按接触角45°配置,因此无论何种姿势都可以使用。
In order to ensure that the four action directions (radial, anti radial, and lateral) on the LM slider have the same rated load, each steel ball column is designed to be configured with a contact angle of 45 °, so it can be used in any posture.
并且因能施加均等的预压,从而既能一边维持较低的磨擦系数,又加强了4个方向的刚性。同时,因断面高度低,并且对LM滑块进行了高刚性设计,从而能获得稳定的高精度直线运动。

And due to the ability to apply equal preload, it can maintain a lower coefficient of friction on one side and strengthen the rigidity in all four directions. Meanwhile, due to the low cross-sectional height and the high rigidity design of the LM slider, stable and high-precision linear motion can be achieved.
4方向等负荷
4-direction equal load
为使LM滑块上的4个作用方向(径向反径向和侧向)均具有相同的额定载荷,各钢球列被设计成按接触角45°配置,因此无论何种姿势都可以使用,用途广泛。
In order to ensure that the four action directions (radial, anti radial, and lateral) on the LM slider have the same rated load, each steel ball column is designed to be configured with a contact angle of 45 °, so it can be used in any posture and has a wide range of applications.
低高刚性
Low center of gravity and high rigidity
通过对LM轨道横断面尺寸的小型化,使变低,同时实现了高刚性。
By miniaturizing the cross-sectional size of the LM track, the center of gravity is lowered while achieving high rigidity.
自动调心能力
Automatic centering ability
由于THK独特的圆弧沟槽的正面组合(DF组合)具有自动调力,即使施加预压也能吸收安装误差,从而得到高精度平滑稳定的直线运动。
Due to THK's unique circular groove front combination (DF combination) with automatic adjustment ability, it can absorb installation errors even when pre pressing is applied, resulting in high-precision, smooth and stable linear motion.
世界标准尺寸
World standard size
的尺寸设计以由直线运动系统之先驱THK所开发的事实上以成为世界标准的全钢球LM滚动导轨HSR型为基准。
The size design is based on the fact that the HSR type of all steel ball LM rolling guide rail, developed by THK, a pioneer in linear motion systems, has become a world standard.
