Description

Technical Field

[0001] This utility model relates to the field of ball bushing technology, and in particular to a guide ball bushing structure. Background Technology

[0002] A guide ball bushing is a guiding component used in mechanical transmission systems. It typically consists of an outer sleeve, balls, and a cage. The balls, supported by the cage, roll within the outer sleeve. Its main function is to provide precise linear guidance for mechanical components, ensuring accurate movement in a straight line, while also bearing the weight and load of the components. Because the friction between the balls and the outer sleeve is rolling friction, which is much less than sliding friction, it effectively reduces friction and helps improve the efficiency of the mechanical system.

[0003] Lubrication of guide ball bushings is crucial for ensuring their normal operation and extending their service life. There are generally two lubrication methods: oil lubrication and grease lubrication. Oil lubrication offers good heat dissipation and low frictional resistance, effectively reducing temperature at high speeds. It is typically achieved through methods such as oil baths, dripping, or spraying. Grease lubrication, on the other hand, is simpler to operate and has lower sealing requirements. The grease forms a thick lubricating film on the surfaces of the balls and bushings, providing good lubrication and protection. It is suitable for applications with low to medium speeds, heavy loads, or where frequent lubrication is inconvenient.

[0004] However, existing guide ball bushing structures often require direct injection or application of lubricant when lubrication is needed. This makes it difficult for the lubricant to penetrate evenly and fully into all critical friction points, creating dead zones that the lubricant cannot reach. Even increasing the amount of lubricant injected cannot guarantee effective lubrication in these areas. Consequently, the guide ball bushing structure cannot effectively add lubricant, which seriously affects the normal operation and service life of the equipment. Therefore, to address these shortcomings, a new guide ball bushing structure is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a guide ball bushing structure, which aims to improve the problem that some guide ball bushing structures in the prior art cannot effectively add lubricating oil.

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

[0007] A guide ball bushing structure includes a bushing ring, a plurality of ball bodies are disposed inside the bushing ring, a lubrication mechanism is disposed outside the bushing ring, and a sealing mechanism is disposed outside the bushing ring.

[0008] The lubrication mechanism includes an outer ring, the interior of which is disposed outside the bushing ring. A fixed ring is fixedly connected to the left side of the outer ring. An oil guiding assembly is disposed on the top of the fixed ring. A flow groove is formed inside the outer ring. Multiple oil outlet grooves are formed inside the outer ring. Multiple receiving grooves are formed outside the bushing ring.

[0009] As a further description of the above technical solution:

[0010] The oil guiding assembly includes an oil inlet pipe, which is externally fixedly connected to the top outer side of the fixing ring, and an oil inlet groove is provided on the top inner side of the fixing ring.

[0011] As a further description of the above technical solution:

[0012] The sealing mechanism includes a first sealing ring, the right side of which is fixedly connected to the left side of the bushing ring, and a second sealing ring is fixedly connected to the outer right side of the bushing ring.

[0013] As a further description of the above technical solution:

[0014] The oil inlet groove is connected to the flow groove, and the flow groove is connected to the plurality of oil outlet grooves;

[0015] As a further description of the above technical solution:

[0016] The oil inlet pipe is externally fixedly connected to the inside of the oil inlet groove, and the receiving groove is an arc-shaped groove.

[0017] As a further description of the above technical solution:

[0018] The flow groove is spiral in shape, and the outer part of the sealing ring is fixedly connected to the inside of the outer ring;

[0019] As a further description of the above technical solution:

[0020] The outer part of the second sealing ring is fixedly connected to the inside of the outer ring, and the bushing ring is made of alloy steel.

[0021] As a further description of the above technical solution:

[0022] The ball bearing body is made of bearing steel, and the outer ring is made of carbon steel.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the oil inlet pipe in the oil guiding assembly ensures that external lubricating oil can be smoothly introduced. The oil inlet groove is further connected to the spiral flow groove inside the outer ring. The spiral flow groove greatly extends the flow path of the lubricating oil, allowing it sufficient time to diffuse evenly. At the same time, the flow groove is connected to multiple oil outlet grooves, and the oil outlet grooves correspond to the receiving grooves outside the bushing ring. The injected lubricating oil can flow evenly from the oil outlet grooves and enter the receiving grooves along the designed path, and finally be fully distributed in the key parts where the bushing ring and the ball body contact, providing a strong guarantee for reducing friction.

[0025] 2. In this utility model, the sealing ring prevents external dust, impurities and other foreign objects from entering the interior from the left and right sides of the bushing ring, thus avoiding damage to the precision fit between the bushing ring and the ball body. On the other hand, it effectively prevents the leakage of internal lubricating oil, ensuring the stable operation of the lubrication system, and thus ensuring that the guide ball bushing structure can continue to operate normally in a good working environment.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0032] Reference Figures 1 to 3This utility model provides an embodiment of a guide ball bushing structure, comprising a bushing ring 1 made of alloy steel. Alloy steel has many advantages such as high strength, good wear resistance, and fatigue resistance, enabling the bushing ring 1 to withstand greater pressure and friction, ensuring stable operation in complex working environments. The bushing ring 1 contains multiple ball bodies 2, which are made of bearing steel. Bearing steel possesses high hardness, high wear resistance, and excellent rolling contact fatigue performance, ensuring stable operation for extended periods under harsh conditions and preventing deformation or excessive wear. A lubrication mechanism 3 and a sealing mechanism 4 are provided on the outside of the bushing ring 1. The lubrication mechanism 3 includes an outer ring 31 made of carbon steel. The inner part of the outer ring 31 is located outside the bushing ring 1. A fixing ring 32 is fixedly connected to the left side of the outer ring 31. An oil guiding component 33 is provided on the top of the fixing ring 32. A flow groove 34 is opened inside the outer ring 31. The spiral design greatly increases the flow path and time of the lubricating oil in the flow groove 34, allowing the lubricating oil to spread more fully. The flow groove 34 is spiral in shape. Multiple oil outlet grooves 35 are opened inside the outer ring 31. The flow groove 34 is connected to the multiple oil outlet grooves 35. The function of the oil outlet grooves 35 is to guide the lubricating oil that has been fully flowed and distributed through the flow groove 34 to the receiving groove 36 outside the bushing ring 1. Multiple receiving grooves 36 are opened on the outside of the bushing ring 1. The receiving grooves 36 are arc-shaped grooves. When the lubricating oil flows out from the oil outlet grooves 35, it can accurately flow into the receiving grooves 36. The arc-shaped groove design helps to collect and store lubricating oil, allowing the lubricating oil to better cover the contact surfaces of the bushing ring 1 and the ball body 2, forming an effective lubricating film and reducing friction and wear between the two.

[0033] Reference Figures 2 to 3 The oil guiding assembly 33 includes an oil inlet pipe 3301, which is fixedly connected to the outer top side of the fixed ring 32. The function of the oil inlet pipe 3301 is to introduce external lubricating oil into the interior of the fixed ring 32. An oil inlet groove 3302 is provided on the inner top side of the fixed ring 32. The oil inlet pipe 3301 is fixedly connected to the interior of the oil inlet groove 3302. The oil inlet groove 3302 is connected to the flow groove 34. The oil inlet groove 3302 ensures that the lubricating oil can be evenly distributed and flow quickly into the flow groove 34 connected to it.

[0034] Reference Figures 1 to 2The sealing mechanism 4 includes a sealing ring 41, the right side of which is fixedly connected to the left side of the bushing ring 1, and the outside of which is fixedly connected to the inside of the outer ring 31. The sealing ring 41 is made of a material with good elasticity and sealing performance, such as rubber or silicone. Its main function is to prevent external dust, impurities, and other foreign objects from entering the bushing ring 1 from the left side, and also to prevent internal lubricating oil from leaking to the left. A sealing ring 42 is fixedly connected to the right side of the bushing ring 1. The outside of the sealing ring 1 is fixedly connected to the inside of the outer ring 31. The sealing ring 42 is also made of a material with high elasticity and excellent sealing performance. Its main function is to prevent external impurities from entering the bushing ring 1 from the right side, and also to prevent lubricating oil from leaking to the right.

[0035] Working Principle: During operation, lubricating oil is first injected into the oil inlet groove 3302 on the top side of the fixed ring 32 through the oil inlet pipe 3301 of the oil guide assembly 33. The oil inlet groove 3302 is connected to the spiral flow groove 34 inside the outer ring 31. The lubricating oil flows along the spiral flow groove 34. Since the flow groove 34 is connected to multiple oil outlet grooves 35, and the oil outlet grooves 35 correspond to the receiving grooves 36 on the outside of the bushing ring 1, the lubricating oil can flow evenly from the oil outlet grooves 35 and enter the receiving grooves 36, thus fully distributing it at the contact points between the bushing ring 1 and the ball body 2, effectively reducing bushing friction and extending its service life. At the same time, the right side of the sealing ring 1 41 is fixed to the left side of the bushing ring 1 and the outside is fixed inside the outer ring 31, and the right side of the sealing ring 1 42 is fixed to the outside of the bushing ring 1 and the outside is also fixed inside the outer ring 31. The two sealing rings prevent dust from entering the bushing and prevent lubricating oil leakage, ensuring the normal operation of the guide ball bushing structure.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
