Technical Problem
[0003]根据直线导轨副的运动特性可知，滑块在有限行程内进行快速往复加减速的直线运动，随着直线导轨副运用的工况领域不断扩大，使用工况速度也随之不断提高，在直线导轨的有限行程范围内，高速运行往往伴随着高加速度，而直线导轨副常由于高加速度过程中的润滑不良导致摩擦副表面出现局部磨损，进而降低了直线导轨的运行精度，缩短了自润滑滚动直线导轨的使用寿命
Benefits of technology
1.通过滚珠循环通道和滚珠的设置，滑块通过设置在滚珠循环通道内的滚珠与导轨滑动连接，滚珠与导轨之间的点接触，能够降低对导轨的磨损，提高导轨的使用寿命；利用自动注油装置的设置，能够通过自动注油装置自动对滚珠循环通道内注入润滑油，更好的维持滚珠与导轨之间的润滑效果，避免滚珠与导轨之间的润滑效果不足，造成导轨副的磨损；
