Round vs. Square Rail Linear Guides

自从上世纪70年代方型或型材直线导轨问世以来,应该选用圆型直线导轨还是方型直线导轨这个关键问题就一直困扰着设计工程师。

方型直线导轨设计固有的各种磨制要求导致其初期成本是圆型直线导轨的数倍,但随着直线导轨制造技术发展以及规模经济效应,方型直线导轨优势日益显现,在更广泛的应用领域中向圆型直线导轨发起有力的挑战。在进入机床领域后,在昔日圆型直线导轨一统天下的许多应用中,型材导轨现在大有后来居上之势。然而,滚珠衬套直线导轨具有许多固有特点以及适合特定应用的有利特性,依然非常流行。

为针对具体应用挑选正确的直线导轨,设计工程师必须认真考察每一种导轨的优点和性能。选错产品意味着不菲的代价,如设计复杂性飙升、功能不良以及总成费用增加等。因此第一步先摸清每种直线导轨的优缺点至关重要。

型材导轨产品非常适合要求高刚度和高精度的高载荷应用。这类直线导轨产品的滚珠轨道通过精密研磨以与滚珠紧密匹配,从而实现优异的性能。型材导轨通常应用于载荷能力、刚度和精度要求十分苛刻的机床工业中。圆型直线导轨具有多种固有优势,例如即使安装表面不够理想,它仍能够平稳运行。
