LINEAR GUIDE ASSEMBLY

摘要

A linear guide assembly has a bar device, multiple partitions, multiple containing spaces and multiple rolling balls. The partitions are mounted between two bars of the bar device at intervals to form the containing spaces. The rolling balls are respectively and rotatably mounted in the containing spaces. Each partition has multiple first protrusions and multiple second protrusions. Each rolling ball is in point-contact with the first protrusions and the second protrusions of adjacent two of the partitions. With the point-contact configuration, an outer surface of each rolling ball is lubricated by much oil.

1. A linear guide assembly comprising:
a resilient bar device having
a front side;a rear side opposite to the front side of the bar device;an extending direction;two bars being parallel to each other, each bar having
an inner side facing that of the other bar and having multiple recesses arranged at intervals, wherein the recesses of the bar respectively align with those of the other bar; multiple partitions mounted between the bars and arranged at intervals along the extending direction of the bar device, each partition having
two first restricted sections respectively and securely mounted on the inner sides of the bars beside the recesses and aligning with each other, each first restricted section having
a front side facing that of the bar device;a rear side opposite to the front side of the first restricted section;two concave first restricted surfaces respectively formed on the front side and the rear side of the first restricted section; andtwo first protrusions respectively protruding from the first restricted surfaces; anda second restricted section located between the two first restricted sections and having
a front side facing that of the bar device;a rear side opposite to the front side of the second restricted section;two concave second restricted surfaces respectively formed on the front side and the rear side of the second restricted section; andtwo second protrusions respectively protruding from the second restricted surfaces; multiple containing spaces formed between the bars beside the partitions and arranged at intervals along the extending direction of the bar device, each containing space formed between adjacent two of the partitions and two of the recesses those align with each other; and multiple rolling balls respectively and rotatably mounted in the containing spaces, each rolling ball being in point-contact with the first protrusions of adjacent two of the partitions and the second protrusions of the adjacent two of the partitions.
