Description

Technical Field

[0001] This utility model relates to the field of ball bushing technology, specifically to a ball bushing assembly for ball bushings. Background Technology

[0002] Ball bushing assemblies are core components in fields such as transmission machinery. Their main function is to convert sliding friction into rolling friction through the cooperation of balls and bushings, thereby reducing frictional resistance during mechanical movement. At the same time, they ensure the coaxiality and stability of component movement, directly affecting the operating accuracy, service life, and maintenance costs of the entire equipment.

[0003] Conventional ball bushings on the market still have some shortcomings in practical applications, such as low lubrication efficiency and poor continuity. The existing lubrication methods of ball bushing assemblies mostly rely on applying grease directly to the surface of the bushing or balls, or reserving simple straight groove oil channels in the bushing. Straight groove oil channels have no guiding structure, and the lubricating oil tends to concentrate at the bottom of the bushing under the action of gravity, and cannot flow evenly to all ball grooves and ball contact points, resulting in some balls and ball grooves experiencing dry friction due to insufficient lubrication, which aggravates wear. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a ball bushing assembly for ball bushings, which solves the problems of low lubrication efficiency and poor continuity of conventional ball bushings in practical applications.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A ball bushing assembly for ball bushings includes: a bushing, wherein balls are disposed inside the bushing; a ball groove is formed on the outer wall of the bushing, a threaded oil groove is formed on the inner wall of the bushing, and sealing rings are symmetrically fixedly connected to the inner wall of the bushing.

[0009] Preferably, the ball grooves are arranged vertically along the outer wall of the bushing, and the vertically arranged ball grooves are arranged in a ring array along the central point of the bushing. The distribution of the ball grooves in a vertical arrangement and a ring array can ensure that multiple balls are evenly stressed and avoid increased wear caused by local overload.

[0010] Preferably, the threaded oil grooves are arranged in a ring around the central point of the bushing, and the interior of the threaded oil grooves is connected to the interior of the ball grooves. The ball grooves are arranged vertically and in a ring array to ensure that multiple balls are evenly stressed, thus avoiding increased wear caused by local overload.

[0011] Preferably, the sealing rings are respectively disposed on the outer ring and the inner ring of the bushing, and the sealing rings are respectively disposed on both ends of the bushing, forming a double sealing barrier inside and outside.

[0012] Preferably, the outer wall of the ball is symmetrically slidably connected with a scraper ring, and the outer wall of the ball is provided with a groove. The rolling of the ball will further carry the lubricating oil in the ball groove to the contact surface through the groove.

[0013] Preferably, the outer wall of the ball is slidably connected to the inner wall of the ball groove, the outer wall of the scraper ring is fixedly connected to the outer wall of the bushing, and the scraper ring is disposed outside the ball groove. The scraper ring can actively scrape off dust, debris and other impurities attached to the surface of the ball, further improving the component's anti-pollution capability.

[0014] (III) Beneficial Effects

[0015] This utility model provides a ball bushing assembly for ball bearing bushings. It has the following beneficial effects:

[0016] (i) The bushing is connected to the ball groove through the threaded oil groove on the inner wall of the bushing and is distributed in a ring array to form a complete lubrication channel network. The lubricating oil injected during assembly or maintenance can flow to the ball groove with the guidance of the threaded structure, and evenly cover the ball surface and the inner wall of the ball groove. During the movement, the rolling of the ball can continuously carry the lubricating oil through the groove to the friction contact surface, replenish the oil film and avoid dry friction.

[0017] (ii) The ball bearing forms a dual impurity protection system through the sealing ring and the scraper ring. The sealing ring is respectively set in the inner ring, outer ring and both ends of the bushing, forming a double sealing barrier inside and outside. It can effectively prevent dust, water stains and external environmental impurities from the guide shaft surface from entering the bushing and ball groove. The scraper ring is fixed on the outer wall of the bushing and sleeved on the outside of the ball bearing. When the ball bearing rolls, the relative sliding between the ball bearing and the inner wall of the scraper ring can actively scrape off the dust, debris and other impurities attached to the surface of the ball bearing, and prevent impurities from getting stuck between the ball bearing and the ball groove and causing abrasive wear.

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a ball bushing assembly for ball bushings, comprising: a bushing 1, wherein a ball 6 is disposed inside the bushing 1; a ball groove 2 is formed on the outer wall of the bushing 1, a threaded oil groove 3 is formed on the inner wall of the bushing 1, and sealing rings 4 are symmetrically fixedly connected to the inner wall of the bushing 1.

[0025] The ball grooves 2 are arranged vertically along the outer wall of the bushing 1, and the vertically arranged ball grooves 2 are arranged in a ring array along the central point of the bushing 1. The distribution of the ball grooves 2 in the form of vertical arrangement and ring array can ensure that multiple balls 6 are evenly stressed and avoid increased wear caused by local overload.

[0026] The threaded oil groove 3 is arranged in a ring around the central point of the bushing 1, and the interior of the threaded oil groove 3 is connected to the interior of the ball groove 2. The ball groove 2 is arranged vertically and in a ring array, which can ensure that multiple balls 6 are evenly stressed and avoid increased wear caused by local overload.

[0027] The sealing rings 4 are respectively set on the outer ring and inner ring of the bushing 1, and the sealing rings 4 are respectively set at both ends of the bushing 1, forming a double sealing barrier inside and outside.

[0028] The outer wall of the ball 6 is symmetrically connected to a scraper ring 5, and the outer wall of the ball 6 is provided with a groove 7. The rolling of the ball 6 will further bring the lubricating oil in the ball groove 2 to the contact surface through the groove 7.

[0029] The outer wall of the ball 6 is slidably connected to the inner wall of the ball groove 2, and the outer wall of the scraper ring 5 is fixedly connected to the outer wall of the bushing 1. The scraper ring 5 is set outside the ball groove 2. The scraper ring 5 can actively scrape off dust, debris and other impurities attached to the surface of the ball 6, further improving the component's anti-pollution ability.

[0030] In use, bushing 1 is the base of the component, and its inner wall forms a sliding base with the outer guide shaft. The ball 6 is embedded in the ball groove 2 on the outer wall of bushing 1.

[0031] When the bushing 1 moves in a straight line or rotation along the guide shaft, the balls 6 roll between the inner wall of the ball groove 2 and the external mating parts, forming rolling friction. The ball groove 2 is arranged in a vertical and circular array, which can ensure that multiple balls 6 are evenly stressed, avoid the wear caused by local overload, and at the same time ensure the coaxiality of the bushing 1 during movement, preventing offset and jamming.

[0032] The threaded oil groove 3 on the inner wall of the bushing 1 is connected to the inside of the ball groove 2, and the threaded oil groove 3 is arranged in a ring array to form a lubrication channel network. During assembly or maintenance, lubricating oil can be injected into the threaded oil groove 3. Due to the guiding nature of the thread structure, the oil will automatically flow along the threaded oil groove 3 to the connected ball groove 2, evenly covering the surface of the ball 6 and the inner wall of the ball groove 2. During the movement, the rolling of the ball 6 will further carry the lubricating oil in the ball groove 2 to the contact surface through the groove 7, continuously replenishing the oil film in the friction area and avoiding dry friction.

[0033] Sealing rings 4 are respectively installed on the inner ring, outer ring and both ends of the bushing 1 to form a double sealing barrier. The inner ring sealing ring 4 can prevent dust and water stains on the guide shaft surface from entering the bushing 1, while the outer ring sealing ring 4 prevents external impurities from entering the ball groove 2 and avoids impurities from getting stuck between the ball 6 and the ball groove 2, which would cause abrasive wear. The scraper ring 5 is fixed on the outer wall of the bushing 1 and is sleeved on the outside of the ball 6. When the ball 6 rolls, its outer wall will slide relative to the inner wall of the scraper ring 5. The scraper ring 5 can actively scrape off the dust, debris and other impurities attached to the surface of the ball 6, further improving the component's anti-contamination ability.
