Linear motion bearing

A linear motion bearing that can be widely used in various linear displacement motions.

Linear bearings are generally known, such as: Bulletin No. I338087 "Linear Displacement Bearing Structure", Bulletin No. D129013 "Linear Bearing Bearing", Announcement No. I294496 "Linear Guide Bearing Device", Announcement No. I276747 "Sliding Device and Used for "Linear sliding ball bearing of the sliding device", Bulletin No. 4,839,991 "Linear Motion Bearing", Bulletin No. 461940 "Linear Rolling Bearing", Bulletin No. 447657 "Structural Improvement of Linear Bearing", Announcement No. 406757 "Linear Bearing Structure Improvement" Announcement No. 399694 "Linear Roller Bearing Structure", Announcement No. 227277 "Linear Ball Bearing Structure", Announcement No. 225576 "Self-Compensated Hydrostatic Linear Motion Bearing and Method" and Publication No. 201522800 "With Convex Linear bearing of the edge" and so on.

In the above-mentioned related linear bearing creation technology, the round ball is used as the bearing and sliding between the bearing fixing portion and the movable portion. However, it can be known from the known technical means that the structure is not only complicated, high in cost, but also difficult to be lubricated and lubricated. At the same time, when any ball wears and deforms, the displacement of the linear sliding will be hindered, so the failure rate is increased due to the number of balls. However, the service life of the integral linear bearing is not good, and in the event of any ball failure, the maintenance is not only difficult, but the entire linear bearing is often discarded in a completely replacement manner, resulting in unnecessary economic loss and unfinished business. The resources used are wasted.

Therefore, the creators of this case have specially improved the above linear bearings in order to simplify the structure, reduce the cost and simple lubrication, maintenance and repair, so as to effectively improve the practical use efficiency and long service life of the linear bearings.

The purpose of the creation of "linear motion bearing" in this case is to provide a linear motion bearing with simple structure, low cost, simple maintenance and repair of parts, high load carrying capacity and long service life.

The creation feature of the present invention is that the fixing portion is provided with at least one accommodating cavity, and at least one or more sliding rails composed of two round bars are arranged in the accommodating cavity; at least one equal number is arranged on the movable portion. a sliding bar corresponding to the sliding portion of the fixed portion; the sliding bar of the movable portion has at least one long pointed corner that can be inserted into the fixing portion to be embedded between the two round bars constituting the sliding rail, and is formed as a whole Linear motion bearing; the movable part is embedded in at least one long sharp corner of the sliding bar between the two round bars of the fixed part sliding rail, and the sharp angle is between 80 degrees and 130 degrees.

The technical creation of positioning the two round rods embedded in the fixed rails by the sharp corners of the sliding parts of the movable part constitutes a linear structure with simple structure, low cost, simple maintenance and repair of parts, high carrying capacity and long service life.

Referring to the embodiment of the "linear motion bearing" of the present invention shown in Fig. 1 of the accompanying drawings, the linear motion bearing includes a fixed portion and a movable portion. In the embodiment of the fixing portion shown in FIG. 1 and FIG. 11 and FIG. 12 , the two sides of the fixing portion 1 are respectively provided with concave receiving cavities 10 , and at least one of the side receiving cavities 10 is disposed at least One or more sets of slide rails composed of two round bars 11 (such as the round bar embodiments shown in Figures 1 and 9 and Figure 10), and the upper and lower edge retaining walls 12 of the opening of each side receiving cavity will The round bars 11 in each of the accommodating cavities 10 are positioned to constitute the slide rails of the respective side accommodating cavities 10 for positioning and sliding displacement of the slide bars 3 of the movable portion.

Referring to the embodiment of the movable part shown in FIG. 1 and FIG. 2 to FIG. 8 , the movable part includes: a substrate 2 and two side sliders 20 integrally fixed with the substrate 2 , and the slide bar holders 20 are disposed on both sides Providing a slide bar 3 inherently corresponding to the slide of the fixed portion 1, the slide bar 3 having at least one length that can be oriented toward the slide rail The strip-shaped sharp corner A is such that the whole movable portion is positioned between the two round bars 11 constituting the slide rail of the fixed portion 1 by the sharp corner A of the slide bar 3, and the movable portion slide bar 3 is embedded in the fixed portion 1 The angle A of the slider A between the two round bars 11 of the slide rail is between 80 degrees and 130 degrees. As shown in Fig. 1, the angle A is applied at an angle of 120 degrees.

Please refer to the assembly diagram of another embodiment of the slide of the creative activity part shown in FIG. 13 . The movable part slide bar 3 has at least one long sharp angle A which can be oriented toward the slide rail and is embedded in the fixed part 1 slide rail. The angle between the two round bars 11 is 90 degrees, and the movable portion slider 3 is as shown in Fig. 13, since the movable portion slider 3 has four long strips of sharp corners A, so the activity The section of the sliding bar 3 has a polygonal shape (the square embodiment shown in the figure), and the at least one long strip-shaped corner A is designed to make the movable sliding bar 3 long after use for a period of time. When the sharp corner A is worn, the installation angle of the movable portion sliding rod 3 can be easily changed, and another long sharp angle A of the movable portion sliding rod 3 is used, thereby achieving the long-term benefit of multiple use of the single sliding rod 3.

The application of this creation is carried out by positioning the sharp corners of the sliding part of the movable part between the two round bars constituting the fixed part sliding rail, so that the following practical benefits can be achieved:

(1) The effect of linear low friction and high linear force between the movable portion and the fixed portion of the integral linear motion bearing is achieved.

(2) It does constitute a linear motion bearing with simple structure, low cost, simple maintenance and renewal of parts, high load carrying capacity and long service life.

(3) When any round bar or slider included in the bearing is worn, the wear component can be updated very quickly.

(4) When any round bar is worn, the angle of the round bar can be easily adjusted and a new support contact line is provided immediately, so that the service life of the round bar is durable.

Therefore, the creation of "linear motion bearings" in this case does have excellent industrial realities. Use and economic efficiency. The above embodiments are only for the purpose of fully illustrating the preferred embodiment of the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art based on the creation of the present technology are within the scope of protection of the present invention.
