Description

Technical Field

[0001] The utility model relates to the technical field of linear bearings, in particular to a three-dimensional linear bearing. Background Art

[0002] Linear bearings are a type of linear motion system used in conjunction with cylindrical shafts for linear travel. Since the load-bearing ball is in point contact with the bearing outer casing, the steel ball rolls with minimal friction resistance. Therefore, linear bearings have low friction and are relatively stable. They do not change with the bearing speed, and can achieve smooth linear motion with high sensitivity and precision. Linear bearings are included in the quick and easy automated selection guide.

[0003] For example, a three-dimensional linear bearing with the authorization announcement number "CN221097201U" solves the problem that the existing three-dimensional linear bearings are not convenient for filtering lubricating oil, which easily causes impurities to enter the cylinder. The above-mentioned method injects lubricating oil into the inner wall of the cylinder, and the sponge sleeve absorbs the lubricating oil, and then the sponge strip absorbs the lubricating oil together. When the steel ball rolls, the sponge strip smears the lubricating oil on the steel ball, which makes it convenient for the staff to smear the lubricating oil on the steel ball. Considering that the lubricating oil is injected into the three-dimensional linear bearing at a single position, it is impossible to ensure that the lubricating oil flows to the sponge strip evenly, resulting in unclear lubrication effect and affecting the service life of some positions. Utility Model Content

[0004] The utility model aims to solve the problem that the lubricating oil in the existing three-dimensional linear bearing cannot flow evenly to the sponge strip, resulting in an unclear lubrication effect and affecting the service life of some positions, and proposes a three-dimensional linear bearing.

[0006] Preferably, the fixing mechanism includes a mounting tube, the outer wall of the mounting tube is tightly pressed against the rubber ring, the inner wall of the mounting tube is processed with a mounting groove, the inner wall of the mounting groove is fixedly connected to the fixing block, the outer wall of the fixing block is fixedly connected to the mounting rod, and the outer wall of the mounting rod is rotatably connected to the ball.

[0007] Preferably, the inner wall of the cylinder is threadedly connected to the second thread ring, and the outer wall of the cylinder is connected to the disassembly mechanism.

[0008] Preferably, the disassembly mechanism comprises a fixing ring and a round block, the outer wall of the fixing ring is threadedly connected to the cylinder, the outer wall of the round block is tightly abutted against the cylinder, the outer wall of the fixing ring is threadedly connected to the long strip, and the outer wall of the long strip is fixedly connected to the round block.

[0009] Preferably, the inner wall of the mounting cylinder is processed with a through hole.

[0010] Preferably, a through groove is processed on the inner wall of the cylinder, and the inner wall of the through groove is connected to the through hole.

[0011] The utility model provides a three-dimensional linear bearing, which has the beneficial effect of: by twisting the fixing ring and the flange on the cylinder, the fixing ring and the flange are detached from the cylinder, and the cylinder is bent to both sides to separate the inner wall of the cylinder from the round blocks on the long strip, lubricating oil can be poured into multiple positions on the upper end of the long strip detached from the cylinder, so that the lubricating oil flows to the through hole, the mounting groove and the ball in turn under the guidance of the through groove, ensuring that the lubricating oil flows evenly to each position, the lubrication effect is more obvious, and the service life is improved.

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings:

[0020] Embodiment 1:

[0021] See also Figure 1-5 : In this embodiment, a three-dimensional linear bearing includes a flange 1 and a cylinder 2. The inner wall of the flange 1 is threadedly connected to the cylinder 2, the inner wall of the flange 1 is processed with a bevel groove 3, the inner wall of the cylinder 2 is threadedly connected to the first thread ring 4, the outer wall of the first thread ring 4 is fixedly connected to the rubber ring 5, and the inner wall of the rubber ring 5 is connected to a fixing mechanism 6.

[0022] The fixing mechanism 6 includes a mounting tube 601, which is rotated into the interior of the cylinder 2 through the first thread ring 4 and the second thread ring 10 to achieve the effect of limiting and fixing the position of the mounting tube 601 in the cylinder 1 by the first thread ring 4 and the second thread ring 10. The outer wall of the mounting tube 601 is tightly pressed against the rubber ring 5, and the inner wall of the mounting tube 601 is processed with a mounting groove 602. The inner wall of the mounting groove 602 is fixedly connected to the fixing block 603, and the outer wall of the fixing block 603 is fixedly connected to the mounting rod 604. The outer wall of the mounting rod 604 is rotatably connected to the ball 605.

[0023] Twist the fixing ring 701 and the flange 1 on the cylinder 2 to separate the fixing ring 701 and the flange 1 from the cylinder 1, and bend the cylinder 2 to both sides to separate the inner wall of the cylinder 2 from the round block 703 on the strip 702, and then pour lubricating oil into multiple positions on the upper end of the strip 702 separated from the cylinder 2, so that the lubricating oil flows to the through hole 8, the mounting groove 602 and the ball 605 in turn under the guidance of the through groove 9, ensuring that the lubricating oil flows evenly to each position, the lubrication effect is more obvious, and the service life is increased.

[0024] The inner wall of the cylinder 2 is threadedly connected to the second thread ring 10, and the outer wall of the cylinder 2 is connected to the disassembly mechanism 7. The disassembly mechanism 7 includes a fixing ring 701 and a round block 703. The fixing ring 701 and the flange 1 are used to detach from the cylinder 1, and the cylinder 2 is bent to both sides so that the inner wall of the cylinder 2 is separated from the round block 703 on the strip 702, thereby achieving the effect of disassembling the strip 702 from the cylinder 2. The outer wall of the fixing ring 701 is threadedly connected to the cylinder 2, and the outer wall of the round block 703 is tightly pressed against the cylinder 2. The outer wall of the fixing ring 701 is threadedly connected to the strip 702, and the outer wall of the strip 702 is fixedly connected to the round block 703.

[0025] Working principle:

[0026] Assembly stage

[0027] First, use a tool to insert the ball 605 on the mounting rod 604 into the mounting groove 602. The mounting rod 604 will be clamped to the fixing block 603, so that the ball 605 is installed on the mounting cylinder 601. Continue to put the mounting cylinder 601 into the cylinder body 1 from the side, and turn the first thread ring 4 and the second thread ring 10 to the inside of the cylinder body 2. The first thread ring 4 and the second thread ring 10 limit the position of the mounting cylinder 601 in the cylinder body 1, realize the assembly of the overall three-dimensional linear bearing, and the external components are in contact with the ball 605, so that the external force drives the ball 605 to roll on the mounting rod 604.

[0028] Maintenance phase

[0029] By twisting the fixing ring 701 on the cylinder 2, the fixing ring 701 is detached from the cylinder 1. Similarly, the flange 1 is detached from the cylinder 2, and the cylinder 2 is bent to both sides to separate the inner wall of the cylinder 2 from the round block 703 on the strip 702. A part of the mounting cylinder 601 inside the cylinder 2 is exposed, and lubricating oil can be poured from the upper end. The lubricating oil is guided by the through groove 9 and flows to the through hole 8, the mounting groove 602 and the ball 605 in turn, so as to reduce the friction between the ball 605 and the outside and increase the service life.

[0030] Embodiment 2:

[0031] See also Figure 1-5 In this embodiment, a through hole 8 is processed on the inner wall of the mounting cylinder 601, and a through groove 9 is processed on the inner wall of the cylinder body 2, and the inner wall of the through groove 9 is connected to the through hole 8.

[0032] Working principle:

[0033] As the lubricating oil flows down through the through groove 9 , the lubricating oil flows from the through hole 8 on the mounting cylinder 601 into the mounting groove 602 , so that the lubricating oil can quickly lubricate the ball 605 and the mounting rod 604 .
