Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to a noise-reducing ball linear guide. Background Technology

[0002] In applications requiring high precision and efficiency, such as CNC machine tools, robots, and automated production lines, noise-reducing ball linear guides are widely used. They ensure the smooth and precise movement of components such as worktables, cutting tools, and robotic arms, thereby improving machining quality and production efficiency. Furthermore, their noise-reducing properties also make them widely applicable in environments requiring quiet operation, such as medical equipment and precision instruments.

[0003] Traditionally, linear guides perform reciprocating linear motion in a given direction. A linear guide pair consists of a slider and a guide rail, and is a rolling guide device. Balls roll and circulate infinitely between the slider and the guide rail, allowing the load platform to move easily and with high precision along the guide rail. This reduces the coefficient of friction to one-fiftieth of that of conventional sliding guides, easily achieving very high positioning accuracy. At the same time, in order to reduce friction and wear, lubricating oil must be added to all the places where the balls roll.

[0004] However, in actual use, traditional devices rely on lubricating oil to wet the surface of the balls for lubrication. After prolonged use, insufficient lubrication may occur, leading to ball wear, increased noise, and reduced lifespan of the slider. Therefore, a noise-reducing ball linear guide is needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the existing technology, lubricating oil is added at intervals to achieve lubrication by wetting the surface of the ball bearings. However, after long-term use, insufficient lubrication will occur, leading to ball bearing wear. Therefore, a noise-reducing ball linear guide is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A noise-reducing ball linear guide includes a guide rail and a slider, which are slidably connected. The slider is provided with a lubrication structure, and a sliding strip is symmetrically and movably connected to the outer side of the slider. Multiple balls are arranged between the guide rail and the slider, and a silencing tube is movably connected to the outer side of the balls. When the slider slides on the guide rail, it drives the sliding strip to slide along the outer side of the guide rail. The movement of the sliding strip pushes the balls to roll along the outer side of the guide rail. The rolling of the balls passes through the inner side of the silencing tube, which reduces noise from the rolling of the balls. The outer side of the slider has multiple guide holes and a first opening, and the outer side of the guide rail has multiple second openings.

[0008] The above technical solution further includes:

[0009] The guide rail has a first sliding groove symmetrically opened on the outer side. The two ends of the slider are symmetrically fixedly connected with U-shaped bars. The opposite sides of the two sets of U-shaped bars are fixedly connected to the slider. The function of the U-shaped bars is to limit the slider and prevent the slider from sliding out from the inside of the slider.

[0010] The sliding bar and the first sliding groove are slidably connected. The inner side of the sliding bar and the multiple balls are movably connected. The multiple balls are movably connected to the outer side of the first sliding groove. The multiple balls are evenly distributed along the sliding bar. The sliding of the sliding bar will drive the multiple balls to slide on the outer side of the first sliding groove.

[0011] The slider has a movable groove on its inner side, and the outer side of the movable groove is movably connected to the silent tube. Multiple balls pass through the inner side of the silent tube, and the balls are movably connected to the silent tube. When the balls roll through the silent tube, the outer side of the balls will be coated with lubricating oil from the inner side of the silent tube.

[0012] The slider has a second sliding groove on its inner side, and the outer side of the second sliding groove is movably connected to the ball, so that the ball will roll on the outer side of the second sliding groove.

[0013] The slider has a placement groove on its inner side. The lubrication structure includes an oil pipe and a permeation strip. The inner side of the placement groove is fixedly connected to the oil pipe, and the outer side of the oil pipe is fixedly connected to multiple permeation strips. The oil pipe stores lubricating oil inside.

[0014] Multiple permeation strips are arranged linearly and evenly along the oil pipe. The end of the permeation strip away from the oil pipe is in contact with the ball. The permeation strip is fixedly connected to the oil pipe. The permeation strip will scrape the lubricating oil in the oil pipe to the outside of the ball.

[0015] Multiple first openings are evenly distributed around the slider in a circular pattern, and multiple second openings are evenly distributed linearly along the guide rail. The second openings allow other devices to be connected to the outside of the guide rail.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, by setting a lubrication structure, the movement of the sliding bar will drive the ball to roll on the outside of the guide rail. The rolling of the ball will pass through the inside of the silent tube. The inside of the silent tube is equipped with lubricating oil. When the ball rolls inside the silent tube, the silent tube will silence the rolling of the ball. The outside of the ball will be coated with lubricating oil. The silent tube can provide the ball with the required lubricating oil, thereby avoiding insufficient lubrication, ball wear, and increased noise after long-term use, which will affect the service life of the slider. It is highly practical.

[0018] 2. In this utility model, the ball will come into contact with the oil pipe when it rolls, and the lubricating oil in the penetrating strip will adhere to the outside of the ball through the oil pipe, thereby further replenishing the lubricating oil on the outside of the ball, thus avoiding insufficient lubrication, ball wear, and increased noise after use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-7As shown, the present invention proposes a noise-reducing ball linear guide, including a guide rail 1 and a slider 3, which are slidably connected. The slider 3 is provided with a lubrication structure. A sliding strip 5 is symmetrically and movably connected to the outer side of the slider 3. Multiple balls 6 are provided between the guide rail 1 and the slider 3. A silencing tube 7 is movably connected to the outer side of the balls 6. When the slider 3 slides on the guide rail 1, it will drive the sliding strip 5 to slide along the outer side of the guide rail 1. The movement of the sliding strip 5 will push the balls 6 to roll along the outer side of the guide rail 1. The rolling of the balls 6 will penetrate the inner side of the silencing tube 7. The silencing tube 7 will reduce noise from the rolling of the balls 6. The balls 6 will contact the oil pipe 11 when rolling. Multiple guide holes 13 and first openings 14 are provided on the outer side of the slider 3. Multiple second openings 15 are provided on the outer side of the guide rail 1.

[0029] The guide rail 1 has a first sliding groove 2 symmetrically opened on the outer side. The two ends of the slider 3 are symmetrically fixedly connected with U-shaped bars 4. The opposite sides of the two sets of U-shaped bars 4 are fixedly connected to the slider 5. The function of the U-shaped bars 4 is to limit the slider 5 and prevent the slider 5 from sliding out from the inside of the slider 3.

[0030] The sliding bar 5 is slidably connected to the first sliding groove 2. The inner side of the sliding bar 5 is movably connected to the multiple balls 6. The multiple balls 6 are movably connected to the outer side of the first sliding groove 2. The multiple balls 6 are evenly distributed along the sliding bar 5. The sliding of the sliding bar 5 will drive the multiple balls 6 to slide on the outer side of the first sliding groove 2.

[0031] The inner side of the slider 3 is provided with a movable groove 8, and the outer side of the movable groove 8 is movably connected to the silent tube 7. Multiple balls 6 pass through the inner side of the silent tube 7, and the balls 6 and the silent tube 7 are movably connected. When the balls 6 roll through the silent tube 7, the outer side of the balls 6 will be covered with the lubricating oil on the inner side of the silent tube 7.

[0032] The inner side of the slider 3 is provided with a second sliding groove 9, and the outer side of the second sliding groove 9 is movably connected to the ball 6, so that the ball 6 will roll on the outer side of the second sliding groove 9.

[0033] The inner side of the slider 3 is provided with a placement groove 10. The lubrication structure includes an oil pipe 11 and a permeation strip 12. The inner side of the placement groove 10 and the oil pipe 11 are fixedly connected. The outer side of the oil pipe 11 and multiple permeation strips 12 are fixedly connected. The inside of the oil pipe 11 stores lubricating oil.

[0034] Multiple penetrating strips 12 are arranged linearly and evenly along the oil pipe 11. The end of the penetrating strip 12 away from the oil pipe 11 is in contact with the ball 6. The penetrating strip 12 is fixedly connected to the oil pipe 11. The penetrating strip 12 will scrape the lubricating oil in the oil pipe 11 to the outside of the ball 6.

[0035] Multiple first openings 14 are evenly distributed around the slider 3, and multiple second openings 15 are evenly distributed linearly along the guide rail 1. The second openings 15 allow other devices to be connected to the outside of the guide rail 1.

[0036] In this embodiment, the movement of the slider 5 causes the ball 6 to roll on the outside of the guide rail 1. The rolling of the ball 6 penetrates the inside of the silent tube 7, which contains lubricating oil. When the ball 6 rolls inside the silent tube 7, lubricating oil adheres to its outside. The silent tube 7 can provide the ball 6 with the required lubricating oil. When the ball 6 rolls, it comes into contact with the oil pipe 11. The lubricating oil in the penetrating strip 12 adheres to the outside of the ball 6 through the oil pipe 11, thereby further replenishing the lubricating oil on the outside of the ball 6. Specifically, when in use, the slider 3 can... When the slider 3 slides on the outside of the guide rail 1, the sliding bar 5 on the inside of the slider 3 will come into contact with the first sliding groove 2. The sliding bar 5 will slide on the outside of the first sliding groove 2. The function of the U-shaped bar 4 is to limit the sliding bar 5 and prevent the sliding bar 5 from sliding out from the inside of the slider 3. The sliding of the sliding bar 5 will drive multiple balls 6 to slide on the outside of the first sliding groove 2. The multiple balls 6 are located between the first sliding groove 2 and the slider 3. The sliding of the slider 3 will drive the sliding bar 5 to move. The movement of the sliding bar 5 will drive the balls 6 to roll on the outside of the guide rail 1.

[0037] The rolling of multiple balls 6 will run through the entire silent tube 7. The silent tube 7 has a self-lubricating and noise-reducing function. When the balls 6 roll through the silent tube 7, the outer side of the balls 6 will be coated with the lubricating oil inside the silent tube 7. When the balls 6 roll inside the silent tube 7, the silent tube 7 will make the balls 6 quiet. During the rolling process, the outer side of the balls 6 will also come into contact with the permeation strip 12. The permeation strip 12 is fixedly connected to the oil pipe 11. The permeation strip 12 will scrape the lubricating oil in the oil pipe 11 onto the outer side of the balls 6, thereby replenishing the lubricating oil on the outer side of the balls 6. Both ends of the oil pipe 11 are fixed to the outer side of the placement groove 10. The guide hole 13 and the first opening 14 can allow the slider 3 to be connected to other devices. The second opening 15 can allow the outer side of the guide rail 1 to be connected to other devices.
