Description

Technical Field

[0001] This utility model relates to the field of annular guide rail technology, specifically a wear-resistant annular guide rail slide. Background Technology

[0002] A circular guide rail, also known as a recirculating guide rail or a circumferential guide rail, is a linear guide rail with a circular trajectory. It consists of components such as a guide rail, a slide, and rollers. The linear or curvilinear motion of the slider is achieved by the rollers rolling on the guide rail.

[0003] Currently, with the continuous development of industrial automation, the requirements for circular guide rail slides are also getting higher and higher. During long-term use, the existing circular guide rail slides will experience wear on the slide itself and the rollers, which will cause jamming during movement. Poor wear resistance will easily lead to damage to the circular guide rail and increase maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a wear-resistant annular guide rail slide to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant annular guide rail slide, comprising an annular guide rail, a bearing slide mounted on the top of the annular guide rail, rollers fixedly mounted at the bottom of the four corners of the bearing slide, roller grooves opened on both sides of the annular guide rail, wear-resistant plates mounted on both sides of the rollers, the two ends of the wear-resistant plates being rolled and locked to the outside of the rollers by screws, and the outer wall of the wear-resistant plates fitting against the inner wall of the roller grooves.

[0006] As a further preferred embodiment of this technical solution, the top of the bearing slide has two symmetrically arranged lubricating oil chambers, the top of the lubricating oil chambers is fixedly installed with a cover, and the bottom of the cover is fixedly connected with a sealing sheet.

[0007] As a further preferred embodiment of this technical solution, the bottom of the bearing slide is provided with a plurality of mounting grooves, each of which is movably connected with wear-resistant balls, and the top of each of the mounting grooves is provided with an oil injection hole, one end of which is connected to a lubricating oil tank.

[0008] As a further preferred embodiment of this technical solution, the upper surface of the annular guide rail is provided with two symmetrically arranged positioning guide grooves, and the bottom of the wear-resistant ball is installed inside the positioning guide grooves.

[0009] As a further preferred embodiment of this technical solution, the wear-resistant sheet is made of cemented carbide material, and the wear-resistant balls are made of high-carbon chromium bearing steel material.

[0010] This utility model provides a wear-resistant annular guide rail slide, which has the following beneficial effects:

[0011] (1) The present invention uses wear-resistant plates to make direct contact between the wear-resistant plates and the annular guide rail, thereby reducing the wear of the rollers during the movement of the bearing slide.

[0012] (2) The present invention uses wear-resistant balls to support the bearing slide. The bottom surface of the bearing slide does not directly contact the top surface of the annular guide rail, which reduces the wear of the bearing slide. In addition, the wear-resistant balls are lubricated with lubricating oil, making the rolling smoother, reducing the wear of the wear-resistant balls themselves, and improving the continuity of the movement of the bearing slide.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] This utility model provides a technical solution: such as Figures 1-4 As shown in this embodiment, a wear-resistant annular guide rail slide includes an annular guide rail 1. A bearing slide 3 is installed on the top of the annular guide rail 1. Rollers 4 are fixedly installed at the bottom of the four corners of the bearing slide 3. Roller grooves 2 are opened on both sides of the annular guide rail 1. Wear-resistant plates 6 are installed on both sides of the roller 4. The two ends of the wear-resistant plates 6 are rolled and locked to the outside of the roller 4 by screws, and the outer wall of the wear-resistant plates 6 is in contact with the inner wall of the roller groove 2. With the wear-resistant plates 6, when the bearing slide 3 moves on the annular guide rail 1, the wear-resistant plates 6 contact the annular guide rail 1 to reduce the wear of the roller 4 during the movement and rotation process.

[0020] The top of the bearing slide 3 has two symmetrically arranged lubricating oil chambers 7. A cover 5 is fixedly installed on the top of the lubricating oil chamber 7, and a sealing plate 8 is fixedly connected to the bottom of the cover 5. When the cover 5 is locked to the top of the lubricating oil chamber 7 by screws, the sealing plate 8 seals the lubricating oil chamber 7. Lubricating oil can be added into the lubricating oil chamber 7 by removing the cover 5.

[0021] The bottom of the bearing slide 3 is provided with several mounting grooves 10, and wear-resistant balls 11 are movably connected inside the mounting grooves 10. The top of the mounting grooves 10 is provided with oil injection holes 12, one end of which is connected to the lubricating oil tank 7. The wear-resistant balls 11 support the bearing slide 3, and the bottom surface of the bearing slide 3 does not directly contact the top surface of the annular guide rail 1, thereby reducing the wear of the bearing slide 3.

[0022] The upper surface of the annular guide rail 1 is provided with two symmetrically arranged positioning guide grooves 9. The bottom of the wear-resistant ball 11 is installed inside the positioning guide groove 9. During the movement of the bearing slide 3, the wear-resistant ball 11 will roll in the positioning guide groove 9. During the rolling, the top of the wear-resistant ball 11 will pass through the oil injection hole 12 and come into contact with the lubricating oil in the lubricating oil tank 7, so that the wear-resistant ball 11 rolls more smoothly, reduces the wear of the wear-resistant ball 11, and improves the continuity of the movement of the bearing slide 3.

[0023] Wear-resistant plate 6 is made of cemented carbide, which has extremely high hardness, excellent wear resistance and corrosion resistance, and is suitable for high temperature, high speed and high load working environment. In guide rail systems that need to withstand extremely high load and wear, cemented carbide is an ideal choice. Wear-resistant ball 11 is made of high carbon chromium bearing steel, which has high hardness, high strength and excellent wear resistance, and can effectively reduce friction and wear.

[0024] This utility model provides a wear-resistant annular guide rail slide, the specific working principle of which is as follows: First, after being installed with wear-resistant plates 6, when the bearing slide 3 moves along the annular guide rail 1, the wear-resistant plates 6 directly contact the roller groove 2 to reduce the wear of the roller 4 during the movement and rotation process. Second, during the movement of the bearing slide 3, the wear-resistant balls 11 will roll in the positioning guide groove 9. During the rolling, the top of the wear-resistant balls 11 will pass through the oil injection hole 12 and come into contact with the lubricating oil in the lubricating oil tank 7. The lubricating oil wets the wear-resistant balls 11 themselves under the rolling of the wear-resistant balls 11, and wets the mounting groove 10 and the positioning guide groove 9, so that the wear-resistant balls 11 roll more smoothly, reduce the wear of the wear-resistant balls 11, and improve the continuity of the movement of the bearing slide 3.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
