LINEAR GUIDEWAY AND CHANNEL MODULE THEREOF

摘要

A channel module of a linear guideway includes a slider, two circulators, and two wire holders. The slider has two opposite inner loading surfaces. The circulators are respectively installed on two opposite sides of the slider and respectively connected to the inner loading surfaces. Each circulator includes an outer loading surface and two corner portions respectively extended from two opposite ends of the outer loading surface to two opposite ends of the corresponding inner loading surface. Each corner portion has a corner surface and a connecting surface. In each corner portion, an altitude difference is formed between an end of the corner surface connected to the connecting surface and the adjacent inner loading surface. The connecting surface is connected to the corresponding inner loading surface seamlessly for eliminating the altitude difference. The wire holders are respectively arranged adjacent to the inner loading surfaces.

主权项

1. A linear guideway, comprising:
an elongated rail defined along a longitudinal direction; a slider having a groove, wherein the slider is movably disposed on the rail via the groove, and the groove has two inner loading surfaces facing each other and parallel to the longitudinal direction; two circulators respectively arranged at two outer sides of the groove: wherein the circulators are respectively connected to the inner loading surfaces of the groove, and each circulator comprises:
an outer loading surface surroundingly defining an external channel, wherein the outer loading surfaces of the two circulators are respectively arranged at two outer sides of the inner loading surfaces; andtwo corner portions each having a corner surface and a connecting surface,wherein in each circulator, the corner portions are respectively extended from two opposite ends of the outer loading surface toward two opposite ends of the corresponding inner loading surface, the corner surface and the connecting surface of each corner portion are sequentially arranged from the corresponding end of the outer loading surface toward the corresponding end of the inner loading surface,wherein in each corner portion, an edge of the corner surface connected to the connecting surface and the corresponding end of the inner loading surface has an altitude difference arranged therebetween, and the connecting surface is seamlessly connected to the corresponding end of the inner loading surface;two wire holders respectively arranged adjacent to the two inner loading surfaces, wherein each wire holder and the corresponding inner loading surface cooperatively define an internal channel;two end caps respectively fixed on two opposite end surfaces of the slider and movably disposed on the rail, wherein each end cap has two retaining troughs recessed on a surface thereof adjacent to the slider, the corner portions of the circulators are respectively inserted into the retaining troughs of the end caps, such that each corner portion and the corresponding retaining trough cooperatively define a corner channel, wherein each internal channel, the two adjacent corner channels, and the adjacent external channel jointly define a circulation channel; anda plurality of rollers received in the circulation channels.
