Embodiment Construction
[0036] like Figure 1 to Figure 4 As shown, a linear guide rail includes a guide rail 1 and a slider. The guide rail 1 includes a guide rail body 11. At least one side of the two sides of the body 11 is provided with a circular arc-shaped guide rail that protrudes outward. The slider includes a slider base 2 (such as Figures 15 to 19 shown), the inner core 4 of the slider located in the slider base 2 corresponding to the side of the guide rail Figure 12 , Figure 13 , Figure 14 shown) and cage 5. Wherein, the other side of the two sides of the main body 11 may adopt other structures that support the slider to slide on the guide rail.
[0037] Wherein, both sides of the guide rail body 11 are provided with outwardly protruding arc-shaped guide rails, and one side of the slider base 2 corresponding to the two guide rails is provided with the slider inner core 4 and all the guide rails. Describe the cage 5.
[0038] The slider inner core 4 is fixed on the slider base 2 ,...

The invention discloses a linear guide rail, which comprises a guide rail and a slide block. The guide rail comprises a guide rail body, and at least one side in two sides of the guide rail body is provided with an arc guiding rail protruding outwards; and the slide block comprises a slide block base arranged on the guide rail, a slide block inner core arranged in the slide block base and corresponding to one side of the guiding rail, and a retainer, wherein the slide block inner core is fixed on the slide block base, at least one annular roll path around the outside periphery of the slide block inner core is formed between the slide block inner core and the retainer, a plurality of ball bearings are arranged in the annular roll path which at least comprises a parallel edge parallel to the guiding rail, and the plurality of the ball bearings in the parallel edge of the annular roll path cling to the guiding rail. Through providing the annular roll path with the parallel edge, the gravity between the plurality of the ball bearing slide blocks and the guide rail is loaded in the parallel edge, and the contact area is increased so as to avoid stress concentration and prolong service life.
Description
technical field [0001] Wooden inventions relate to linear guides. Background technique [0002] Linear guides are widely used in mechanical devices, transmission systems and woodworking machinery, such as Figure 27 As shown, it generally includes a guide rail and a slider, wherein the slider is slidably fixed on the guide rail. Figure 27 It is an existing linear guide, which includes a slider 100, an outer ring 101, a steel ball 102, a cage 103, a guide rail 104, an aluminum bracket 105, and a screw 106, which restricts the degree of freedom of the steel ball 102 through the cage 103, It forms a ring-shaped steel ball chain, so that the slider 100 slides on the guide rail 104, and the steel ball 102, the outer ring 101 and the guide rail 105 can also rotate relative to each other, and their contact is point contact. This type of linear guide has the following disadvantages: [0003] 1. Since there are only a few bearing weights in the steel balls 102, the slider 100 is pr...
