Description

Technical Field

[0001] This utility model relates to the field of linear motion bearing technology, and in particular to a simple oil film lubrication structure for a linear motion bearing, which has at least two rod-shaped bearings with polygonal cross-sections, a slide block and a slide rail, as well as an inner concave oil storage groove and an oil wiping spring provided in the slide rail, to form a simple oil film lubrication structure for easy application and generation of oil film lubrication. It has the effects of simple oil storage structure, low cost, high lubrication efficiency, quiet and smooth movement, and dust and scale prevention. Background Technology

[0002] Generally known linear motion bearing structures are composed of slide blocks and slide rails in conjunction with ball bearings. Such technologies have disadvantages such as complex structure, numerous components, time-consuming and labor-intensive assembly and production, high cost, and noticeable motion noise. Furthermore, after a period of use, the ball bearings wear out and cannot be easily replaced, so their service life is limited, resulting in limited industrial applicability and poor economic benefits.

[0003] Therefore, the creator of this invention developed this technology to address the shortcomings of the aforementioned traditional technologies, thereby improving upon the known limitations of traditional technologies, such as complex structures, numerous components, time-consuming and labor-intensive assembly and production, high costs, and noticeable noise during operation. Utility Model Content

[0004] To address the shortcomings of known traditional technologies, this invention presents a simplified oil film lubrication structure for linear motion bearings. The purpose of this invention is to:

[0005] 1. A simple oil film lubrication structure is provided for linear motion bearings that is simple in structure, low in cost, provides quiet and smooth motion lubrication, and improves load-bearing capacity.

[0006] 2. A simple oil film lubrication structure is provided that provides excellent lubrication, quiet and smooth operation, and prevents dust and scale buildup.

[0007] 3. A simple oil film lubrication structure for linear motion bearings with excellent industrial applicability and high economic benefits is provided.

[0008] 4. Effectively improves upon the shortcomings of known linear motion bearings, such as complex structure, numerous components, time-consuming and labor-intensive assembly and production, high cost, and limited service life.

[0009] The innovative feature of this utility model's simplified oil film lubrication structure for linear motion bearings is that it includes: a slide block, a slide rail, a rod-shaped bearing, and a recessed oil storage groove and an oil-lubricating spring provided in the slide rail. One or more recessed grooves are provided between the opposing surfaces of the slide rail and the slide block. The shape of the recessed groove in the slide rail is symmetrical to the shape of the recessed groove in the slide block. The space between the recessed groove in the slide block and the recessed groove in the slide rail is for the rod-shaped bearing.

[0010] The slide rail has an oil reservoir recessed to a set depth and height in its inner groove.

[0011] The slide rail is equipped with an oil slurry containing an oil-applying spring that has both telescopic and binding elasticity.

[0012] The outer diameter of the oil-absorbing spring with telescopic and binding elasticity is equal to or less than the set depth and height of the oil storage groove in the inner groove of the slide rail.

[0013] The oil reservoir of the slide rail is a concave oil reservoir set around the perimeter of the slide rail.

[0014] The oiling spring of the slide rail is a positioning ring placed in the oil storage groove of the slide rail;

[0015] The cross-sectional shape of the rod bearing is a polygon with multiple angles, and at least one angle of the polygon is an arc angle.

[0016] By using rod-shaped bearings installed in the opposing recessed grooves on the corresponding surfaces of the slide block and slide rail, as well as the recessed oil storage groove and oil wiping spring provided on the slide rail, a simple oil film lubrication structure for linear motion bearings that can easily generate oil film lubrication is formed. This structure is simple in oil storage, low in cost, high in lubrication efficiency, quiet and smooth in motion, and also has the effects of preventing dust and dirt. Attached Figure Description

[0030] 23 Oiling spring; 24 Auxiliary oiling groove; 3 Rod-shaped bearing; 31 Arc angle. Detailed Implementation

[0031] Please see Figures 1 to 11 The diagram shows a simplified oil film lubrication structure for the linear motion bearing of this invention, comprising: a slide block 1, a slide rail 2, an oil reservoir 22, an oil slick spring 23, and a rod-shaped bearing 3.

[0032] As shown in the figure, there is one or more recessed grooves 11 and 21 (V-shaped with an inner angle of 90 degrees as shown in the figure) between the opposing surfaces of the slide rail 2 and the slide seat 1. The shape of the recessed groove 21 of the slide rail 2 is symmetrical to the shape of the recessed groove 11 of the slide seat 1, and the space between the recessed groove 11 of the slide seat 1 and the recessed groove 21 of the slide rail 2 is the space for the rod bearing 3.

[0033] As shown in the figure, the rod bearing 3 is a polygonal rod bearing. This rod bearing 3 is disposed in the opposing inner grooves 11 and 21 on the corresponding surfaces of the slide block 1 and the slide rail 2. The cross-sectional shape of the rod bearing 3 is a polygonal shape, as shown in the figure. In the preferred embodiment, it is a quadrilateral shape, and the cross-sectional shape of this quadrilateral is a square. Furthermore, at least one corner of the polygonal shape is an arc angle 31. Figure 8 and Figure 9 (The four arc-shaped angles shown are for illustrative purposes only.) The length of the rod-shaped bearing 3 is equal to or less than the length of the slide 1.

[0034] Additionally, the inner groove 21 of the slide rail 2 has an oil storage groove 22 recessed to a predetermined depth and height. The oil storage groove 22 is equipped with an oiling spring 23 or other similar oiling component with telescopic and binding elasticity. The outer diameter of the oiling spring 23 is equal to or smaller than the predetermined depth and height of the oil storage groove 22 in the inner groove. The oil storage groove 22 can be configured as follows: Figures 1 to 4The embodiment shown is an oil storage groove with an inner recess around the slide rail 2. The oil wiping spring 23 is positioned in the oil storage groove 22 of the slide rail 2. The outer diameter of the oil wiping spring 23 is equal to or less than the set depth and height of the oil storage groove 22 of the slide rail 2.

[0035] Please refer to the following: Figures 10 to 11 At least one concentric auxiliary oiling groove 24 can be provided at the inclined plane of the inner groove 21 of the other slide rail 2. The groove of at least one concave ring of the auxiliary oiling groove 24 is connected to the oil storage groove 22 of the inner groove of the slide rail 2. When the slide block 1 moves and slides in the inner groove 21 of the slide rail 2, the connecting force of the movement of the slide block 1 causes the oil storage groove 22, the oiling spring 23 and the auxiliary oiling groove 24 of the slide rail 2 to move simultaneously to output lubricating grease, so as to generate an excellent long-lasting lubrication function by applying an oil film between the inner groove 11 of the slide block 1 and the inner groove 21 of the slide rail 2.

[0036] In summary, this utility model has the following practical benefits and functions:

[0037] 1. A simple oil film lubrication structure can be provided for linear motion bearings that are simple in structure, low in cost, quiet and smooth in motion lubrication, and have improved load-bearing capacity.

[0038] 2. It can indeed produce industrial practical benefits such as excellent lubrication, quiet and smooth operation, and dust and scale prevention.

[0039] 3. It can truly achieve the characteristics and objectives of innovation and progress with excellent industrial utilization and high economic benefits.

[0040] 4. It can effectively improve the lubrication effect of known linear motion bearings and effectively solve the shortcomings of known bearings such as complex structure, numerous components, time-consuming and labor-intensive assembly, poor lubrication effect, and limited service life.
