Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of retainer chain, especially a retainer chain and a linear guide rail with the retainer chain. BACKGROUND

[0002] In the linear guide rail, the rolling body is designed to circulate on the surface of the slider and the rail, and each rolling body is installed in the retainer chain separator. The middle of the retainer chain separator is a circular arc groove that can wrap the rolling body. The middle recessed part of the side of the retainer can store lubricant as a lubrication groove, providing the lubrication required when the rolling body rotates.

[0003] However, the curvature radius of the existing retainer chain separator is greater than that of the rolling body, which not only increases the resistance between the rolling body and the retainer chain separator when the groove wraps the rolling body, but also gradually accumulates the lubricating oil on the upper and lower surfaces of the retainer chain separator when the rolling body rotates, making it difficult for the lubricating oil stored in the middle recessed part to flow. This also reduces the service life of the retainer chain lubricating oil. When the lubricating oil accumulates to a certain stage, it increases the overall weight of the retainer chain, affecting the stability of the overall movement of the guide rail.

Preferably, as shown in the drawings, the first face 133 and the second face 143 are both inclined faces, and the third face 134 and the fourth face 144 are both inclined faces. Figure 4

[0047] During assembly, the separator monomer 1 separates the rolling bodies 3, and the separator monomers 1 are linked together through the retaining chain arm parts 2. At the same time, since the curvature radius of the rolling body 3 is smaller than that of the first circular-arc-face 13 and the second circular-arc-face 14, the rolling body 3 forms the first circular-arc-face groove 15 and the second circular-arc-face groove 16 with the separator monomer 1, so that the lubricating grease can be stored, and the maintenance period of the guide rail can be prolonged.

[0048] ​The utility model discloses a first opening groove 11, second opening groove 12 are set up respectively on the both sides of separator monomer 1 with the direct contact of rolling body 3, make lubricating oil can flow into second circular arc groove 16, first circular arc groove 15 among through first opening groove 11, second opening groove 12, also can make the lubricating oil stored in first circular arc groove 15, second circular arc groove 16 flow out through first opening groove 11, second opening groove 12 by the change of rotation direction, in addition through the structure design of the up and down staggered and left and right staggered of first opening groove 11, second opening groove 12 make the strength influence of the slotted design to separator monomer 1 be controlled within a certain degree.

Specifically, the existence of third line contact 33 and fourth line contact 34 makes lubricating oil be blocked and gradually accumulate in first groove 171, third groove 181, fourth groove 182, second groove 172 when first groove 171, second groove 172, third groove 181, fourth groove 182 can not accommodate more lubricating oil, lubricating oil will accumulate in the upper and lower parts (i.e. first face 133, second face 143, third face 134, fourth face 144) of separator monomer 1, when the lubricating oil in first groove 171, third groove 181, fourth groove 182, second groove 172 is consumed, the lubricating oil accumulated in the upper and lower parts of separator monomer 1 will also be affected by gravity and rolling body 3 fluctuation gradually slip in the surface of rolling body 3, gradually slip in first groove 171, third groove 181, fourth groove 182, second groove 172 in turn. And when first groove 171, third groove 181, fourth groove 182, second groove 172 accommodate lubricating oil, first opening groove 11, second opening groove 12 will also store part lubricating oil in first circular arc groove 15, second circular arc groove 16. When rolling body 3 rotates, the lubricating oil accumulated in first groove 171, third groove 181, fourth groove 182, second groove 172 will directly contact with rolling body 3, will smear the lubricating oil of first groove 171, third groove 181, fourth groove 182, second groove 172 on the surface of rolling body 3 and complete lubrication, this can prolong the service life of lubricating oil, also can reduce the influence of lubricating oil accumulation to the running stability of guide rail to a certain extent.
