Technical Field

[0001] This application relates to the field of linear bearing accessories technology, and more specifically to a ring for a linear bearing. Background Technology

[0003] Patent document (CN2898420Y) discloses a linear bearing, including a bearing ring composed of a plastic housing and ball bearing pads. Different materials are selected based on the stress level, resulting in lower cost. However, due to the split design of the bearing ring, assembly is cumbersome, and the structural strength is relatively low. Furthermore, during operation, the heat generated by the friction between the balls and the bearing rings accelerates the wear of both.

[0004] Therefore, there is a need for a linear bearing race that is machined in one piece, has high structural strength, and provides conditions for high heat dissipation. Summary of the Invention

[0011] In one or more embodiments of this application, both ends of the collar have waist-shaped holes, and both ends of the cooling pipe pass through the corresponding waist-shaped holes.

[0012] In one or more embodiments of this application, each of the oblong holes has a threaded hole, and the linear bearing race also includes a threaded post, which is screwed into the threaded hole and fits against the end of the cooling pipe passing through the oblong hole.

[0018] The terminology used herein is for the purpose of describing various embodiments only and is not intended to be limiting. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. It will also be understood that the terms “comprising” and / or “having” as used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or groups thereof.

[0019] Indicative linear bearing race, reference Figures 1 to 4 According to a preferred embodiment of the present invention, a linear bearing race includes a race body 10, the race body 10 having a through hole 101, the wall of the through hole 101 including a plurality of first grooves 1011 arranged in a ring array, a protrusion 1012 between two adjacent first grooves 1011, a second groove 10121 in the middle section of the protrusion 1012, and both ends of the protrusion 1012 having conical surfaces 10122, and each of the two conical surfaces 10122 having a cylindrical surface 10123 and a first chamfer 10124 at the opposite end, and the first chamfer 10124 having a first annular groove 1013 at the end away from the cylindrical surface 10123.

[0020] It should be noted that, in actual processing, the first groove 1011 and the protrusion 1012 are machined first, and then the conical surface 10122 is machined. In use, the external balls reciprocate between the first groove 1011 and the second groove 10121. This application sets the cross-sectional shape of the through hole 101 to the above shape to suit a specific linear bearing cage. In addition, compared with the prior art where the ring body 10 is a split design, this application has the advantages of integrated processing and higher structural strength.

[0021] In addition, to facilitate the connection of the external clamp connector to the collar body 10, such as Figure 2 As shown, one end of the outer side wall of the collar body 10 has a second annular groove 1014.

[0022] It should be noted that, during use, one end of the external sleeve connector is fitted into the second annular groove 1014 and tightened around the collar body 10, while the other end of the external sleeve connector is connected to the external component that needs to slide.

[0023] Furthermore, the reciprocating flow of the balls between the first groove 1011 and the second groove 10121 generates heat and accelerates wear, thus providing conditions for heat dissipation of the ring body 10, such as... Figure 2 As shown, the middle section of the outer side wall of the collar body 10 has a spiral groove 102, and a cooling pipe 20 is provided in the spiral groove 102.

[0024] It should be noted that in actual use, the external water storage device sends coolant into the cooling pipe 20 through the pump body, and returns to the external water storage device after circulating multiple times. During the flow process, the coolant carries away the heat on the ring body 10, thereby reducing the impact of temperature on the wear of the ring body 10. Compared with the prior art, it has the advantage of providing conditions for high heat dissipation.

[0025] Furthermore, to achieve protection for the cooling pipe 20, such as... Figure 2 As shown, the end of the ring body 10 opposite to the second annular groove 1014 has a third annular groove 103. The third annular groove 103 is connected to the spiral groove 102. The ring for the linear bearing also includes a collar 30, which is sleeved on the third annular groove 103 and covers the cooling pipe 20.

[0026] More specifically, such as Figure 4 As shown, both ends of the collar 30 have waist-shaped holes 301, and both ends of the cooling pipe 20 pass through the corresponding waist-shaped holes 301.

[0027] It should be noted that the cooling tube 20 is first wound in the second annular groove 1014, and then the collar 30 is inserted into the third annular groove 103 and rotated at a predetermined angle so that both ends of the cooling tube 20 are directly opposite the waist-shaped hole 301. By setting the waist-shaped hole 301, conditions are provided for easy removal of the cooling tube 20.

[0028] Furthermore, such as Figure 4 As shown, each of the waist-shaped holes 301 has a threaded hole 3011, and the linear bearing ring also includes a threaded post 40, which is screwed into the threaded hole 3011 and fits against the end of the cooling pipe 20 that passes through the waist-shaped hole 301.

[0029] It should be noted that after the end of the cooling pipe 20 extends out of the waist-shaped hole 301, the threaded post 40 is screwed in. Since the sidewall of the threaded post 40 fits against the cooling pipe 20, it provides a length-direction limit for the cooling pipe 20 within the waist-shaped hole 301. Furthermore, since the cooling pipe 20 passes through the collar 30 and is wound around the second annular groove 1014, the cooling pipe 20 and the collar 30 will mutually limit each other, making it difficult for the collar 30 to disengage from the third annular groove 103.

[0030] In summary, the linear bearing race described in the embodiments of this application is explained, which provides advantages such as one-piece machining, high structural strength, and conditions for high heat dissipation.

[0031] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from these principles.
