Description

Technical Field

[0001] The utility model relates to the technical field of seat bearings, in particular to a seat bearing with good sealing performance. Background Art

[0002] A bearing seat is a bearing that combines a rolling bearing with a bearing seat. Generally, the rolling bearing is fixed inside the bearing seat, and the relative position of the rolling bearing and the bearing seat will not change. The inner ring of the rolling bearing is generally connected to the shaft parts, resulting in the bearing seat being mostly parallel to the shaft parts during installation. However, inside some devices or equipment, due to limited installation space, part of the outer shell of the bearing seat may conflict with other parts in the device or equipment, affecting the installation of the bearing seat, which is inconvenient. In addition, general bearings need to be installed with rubber seals to prevent dust from entering the bearing raceway and affecting the bearing rotation, and the rubber seals are used to prevent the lubricating oil from flowing out. However, general bearing rubber seals will generate high contact pressure with the inner ring of the bearing, which can easily cause friction, affect the bearing running speed and cause high temperature, which is inconvenient.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 6 In an embodiment of the utility model, a bearing seat with good sealing performance includes a housing 100, and cutting holes 101 are opened on opposite sides of the housing 100, a bearing mechanism 400 is arranged inside the housing 100, and the bearing mechanism 400 is equipped with an adjustment mechanism 300;

[0024] The adjustment mechanism 300 includes two support rods 310, and one end of the two support rods 310 is fixedly connected to the bearing mechanism 400, the two support rods 310 are symmetrically arranged with the central axis of the two cutting holes 101 as the center, and the other ends of the two support rods 310 are provided with internal threaded tubes 320, the outer side walls of the two internal threaded tubes 320 are rotatably connected to the other ends of the adjacent support rods 310, the inner side walls of the two cutting holes 101 are fixedly connected to two connection frames 330, and the top and bottom sides of the four connection frames 330 are provided with guide grooves 331, and any connection frame 3 A sleeve 340 is provided inside each of the sleeves 340, and two sliders 341 are fixedly connected to the outer side wall of any sleeve 340. The two sliders 341 on the same sleeve 340 are respectively slidably engaged in the two guide grooves 331 on the adjacent connecting frame 330. A screw 350 is provided between the two sleeves 340 which are respectively located in the two cutting holes 101 and are parallel to each other, and the outer side walls of the two screws 350 are rotatably sleeved with the inner side walls of the two adjacent sleeves 340, and the inner side walls of the two internal threaded cylinders 320 are respectively screwed with the outer side walls of the two screws 350.

When the shell 100 needs to be installed at an angle due to space problems, the user can rotate the two screws 350 as needed. When the two screws 350 rotate, the relative positions between themselves and the adjacent sleeves 340 will not change, so that the two screws 350 drive the two internal threaded tubes 320 to move. By adjusting the positions of the two internal threaded tubes 320 on the adjacent screws 350, the bearing mechanism 400 is controlled to deflect inside the shell 100, thereby changing the installation position of the shell 100, so that the user can adjust the installation position of the shell 100 by adjusting the deflection angle of the bearing mechanism 400 inside the shell 100, so that the user can install the seated bearing as needed. Embodiment 1

[0026] like Figure 4-6 As shown, in this embodiment, the bearing mechanism 400 includes an annular shell 410, and the outer side wall of the annular shell 410 is fixedly connected to one end of the two support rods 310, a bearing outer ring 420 is arranged inside the annular shell 410, and a rubber ring 421 is fixedly connected to the outer side wall of the bearing outer ring 420, and the rubber ring 421 is movably clamped between two opposite inner side walls of the annular shell 410, a bearing inner ring 430 is arranged inside the bearing outer ring 420, and the inner side wall of the bearing outer ring 420 and the outer side wall of the bearing inner ring 430 are both provided with raceways, and a plurality of balls 401 are slidably clamped between the two raceways.

[0027] In this embodiment, the bearing outer ring 420 and the bearing inner ring 430 are fixed in relative position based on the clamping connection between their own raceways and the ball 401, and the bearing inner ring 430 can rotate inside the bearing outer ring 420. The bearing inner ring 430 is used to connect with shaft parts. The bearing mechanism 400, the adjustment mechanism 300 and the housing 100 constitute a complete seated bearing. When the bearing is damaged or requires maintenance that affects the overall operation of the seated bearing, the bearing outer ring 420 can be removed from the inside of the annular shell 410, and then the rubber ring 421 on the new bearing mechanism 400 is clamped into the inside of the annular shell 410, thereby replacing the entire bearing mechanism 400. The rubber ring 421 has its own rubber properties and elasticity, and can be clamped into the inside of the annular shell 410 by extrusion to be fixed.

[0028] like Figure 1-6 As shown, in the present embodiment, an annular filter screen 413 is fixedly connected between two opposite inner walls of the annular shell 410, a rotating rod 412 is fixedly connected to the bottom end of the outer wall of the annular shell 410, and the bottom end of the rotating rod 412 is rotatably connected to the inner wall of the shell 100, an oil filling pipe 411 is fixedly connected to the top surface of the annular shell 410, and the top end of the oil filling pipe 411 passes through the top surface of the shell 100, and the interior of the oil filling pipe 411 is connected to the interior of the annular shell 410.

[0029] In a specific implementation, the deflection angle of the annular shell 410 and the bearing mechanism 400 as a whole can be limited by the rotating rod 412 and the oil filling pipe 411, so that the annular shell 410 and the bearing mechanism 400 always rotate around the central axis of the rotating rod 412 when deflecting inside the shell 100. When the rubber ring 421 is inserted into the annular shell 410, the rubber ring 421 can be close to the annular filter 413 to limit the rubber ring 421 to prevent the rubber ring 421 from shaking inside the annular shell 410. There is a certain gap between the rubber ring 421 and the two opposite inner walls of the annular shell 410. After the user injects lubricating oil into the annular shell 410 through the oil filling pipe 411, the lubricating oil can flow out through the mesh on the annular filter 413 and the gap between the inner wall of the annular shell 410 and the rubber ring 421. Embodiment 2

[0030] On the basis of the first embodiment, the lubricating oil is blocked by providing an L-shaped connecting ring 440 and an L-shaped clamping ring 450 .

[0031] like Figure 4-6As shown, in this embodiment, an L-shaped connecting ring 440 is fixedly connected to one side of the annular shell 410, and a sealing ring 441 is fixedly sleeved on the inner wall of the L-shaped connecting ring 440, a slot 431 is opened on the outer wall of the bearing inner ring 430, and the sealing ring 441 is movably snapped into the inside of the slot 431, a collar 460 is fixedly sleeved on the outer wall of the bearing inner ring 430, and a rubber ring 461 is fixedly sleeved on the outer wall of the collar 460, an L-shaped snap ring 450 is fixedly connected to the other side of the book-searching annular shell 410, and the rubber ring 461 is movably snapped into the inside of the L-shaped snap ring 450, and two connecting plates 200 are fixedly connected to the bottom surface of the shell 100.

[0032] In a specific implementation, the cross sections of the L-shaped snap ring 450 and the L-shaped connecting ring 440 are both L-shaped. When the bearing outer ring 420 is inserted into the annular shell 410 through the rubber ring 421, the groove 431 on the bearing inner ring 430 is clamped by the sealing ring 441, and the rubber ring 461 is inserted into the L-shaped snap ring 450. The sealing ring 441 and the rubber ring 461 are both made of rubber and have a certain elasticity. The inner wall of the sealing ring 441 and the outer wall of the rubber ring 461 are both rounded structures, so that the sealing ring 441 After the inner wall is inserted into the slot 431, it can be restored to be close to the inner wall of the slot 431. The outer wall of the rubber ring 461 can also be inserted into the L-shaped snap ring 450 and then restored to be close to the inner wall of the L-shaped snap ring 450, further fixing the bearing inner ring 430. At the same time, lubricating oil can be injected through the oil injection pipe 411, and the lubricating oil flows out through the gap between the inner wall of the annular shell 410 and the rubber ring 421 to the space between the L-shaped snap ring 450 and the annular shell 410, and between the L-shaped connecting ring 440 and the annular shell 410. Then these two The lubricating oil at the inner ring 430 of the bearing will flow into the two raceways through the gap between the bearing inner ring 430 and the bearing outer ring 420 to lubricate the ball 401, and when the bearing inner ring 430 is driven to rotate by the shaft parts, the lubricating oil between the L-shaped retaining ring 450 and the annular shell 410, and between the L-shaped connecting ring 440 and the annular shell 410 will naturally lubricate the edge of the sealing ring 441 and the edge of the rubber ring 461, and due to the rounded structure of the rubber ring 461 and the sealing ring 441, the rubber ring 461 and the sealing ring The contact area between 441 and the L-shaped retaining ring 450 and the retaining groove 431 is small, so when the bearing inner ring 430 rotates, the friction between the sealing ring 441 and the retaining groove 431 is reduced due to the lubrication of the lubricating oil, and the friction between the rubber ring 461 and the inner wall of the L-shaped retaining ring 450 is reduced due to the lubrication of the lubricating oil, thereby reducing the resistance and temperature when the bearing inner ring 430 rotates. The top surface of the mounting plate 200 has a hole for the connecting piece to pass through. The user can use the connecting piece to pass through the hole on the mounting plate 200 and then connect it to an object.
