Description

Technical Field

[0001] This utility model belongs to the field of bearing technology, and more specifically, it relates to an outer spherical ball bearing with a set screw. Background Technology

[0002] Spherical roller bearings with set screws typically have two set screws with an included angle of 120°. During installation, tightening the set screws presses the ends of the set screws firmly against the surface of the equipment shaft. This uses friction to fix the relative position of the bearing inner ring and the equipment shaft, preventing the bearing from moving or rotating axially along the equipment shaft. They are widely used in manufacturing industries such as textile machinery, ceramic machinery, agricultural machinery, and construction machinery. They generally consist of an outer ring, an inner ring, rolling elements, a cage, and seals on both sides.

[0003] Existing application number: CN201720761994.8. This utility model relates to the technical field of bearings, and in particular to an external spherical roller bearing. It has a bearing body, which includes an outer ring, an inner ring, a cage, and bearing balls mounted between the outer and inner rings via the cage. Two bearing seals are also mounted between the outer and inner rings via a bearing seal ring skeleton, symmetrically positioned on both sides of the bearing balls. Both bearing seals are double-lip seals, with the two lips of each seal making oblique elastic contact with the inner ring to form a labyrinth seal structure. This external spherical roller bearing provides a significant sealing effect, making it difficult for external substances to enter the bearing.

[0004] Based on the above, in scenarios such as downhole equipment, compact motors, and automotive chassis components, the alignment of the bearing inner ring with the equipment shaft often faces significant challenges due to the limited installation space. Traditional installation methods require repeated adjustments to the relative positions of the shaft and bearing, which is not only time-consuming and labor-intensive but also prone to causing scratches on the surface of the equipment shaft due to improper operation, thereby affecting the equipment's performance and lifespan. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an external spherical ball bearing with set screws. This solves the problem that in scenarios such as downhole equipment, compact motors, and automotive chassis components, where the installation space is limited, aligning the inner ring of the bearing with the equipment shaft often presents significant challenges. Traditional installation methods require repeated adjustments to the relative positions of the shaft and bearing, which is not only time-consuming and labor-intensive but also prone to causing scratches on the surface of the equipment shaft due to improper operation, thereby affecting the performance and lifespan of the equipment.

[0006] The purpose and effect of this utility model of an external spherical ball bearing with a set screw are achieved by the following specific technical means: A spherical roller bearing with set screws includes an outer ring, an inner ring, a sealing cap, set screws, a collar, a connecting box, a fixing box, a guide assembly, and an anti-damping assembly. The inner ring is disposed inside the outer ring. Two sealing caps are provided, and the two sealing caps are respectively fixedly connected to the left and right sides of the outer ring. Two set screws are provided, and the two set screws are threadedly connected to the left end of the inner ring. The collar is sleeved on the outer side of the right end of the inner ring. The connecting box is fixedly connected below the collar. The fixing box is fixedly connected below the connecting box. The guide assembly is disposed on the right side of the outer ring. The anti-damping assembly is disposed outside the two set screws.

[0007] Furthermore, the guide assembly includes a sliding rod and a sliding pin; the top of the sliding rod is slidably connected inside the fixing box; and the sliding pin is fixedly connected to the top of the sliding rod.

[0008] Furthermore, the guide assembly also includes: a fixing spring, a connecting block, and a connecting groove; the top of the fixing spring is fixedly connected to the bottom of the sliding rod, and the bottom of the fixing spring is fixedly connected to the inside of the fixing box; the connecting block is fixedly connected to the bottom right side of the sealing cover on the right side; the connecting groove is formed inside the connecting block.

[0009] Furthermore, the guide assembly also includes a limiting ring and a horn ring; the limiting ring is fixedly connected to the right side of the collar, and the left end face of the limiting ring is in contact with the right end face of the bearing inner ring; the horn ring is fixedly connected to the right side of the limiting ring.

[0010] Furthermore, the anti-pressure injury component includes: a control plate; the control plate is provided in two sets, each set of the control plate is provided in two pieces, and the two sets of the control plates are respectively fixedly connected to the outer ends of the two set screws.

[0011] Furthermore, the anti-pressure injury component also includes: a silicone block and a silicone sleeve; the silicone block is inserted into the inner end of the outer end of a front set screw; the silicone sleeve is fixedly connected to the front end of the silicone block.

[0012] Compared with the prior art, the present invention has the following beneficial effects: First, by pulling down the sliding rod, in conjunction with the connecting box and connecting block, the collar, limit ring, and horn ring can be quickly assembled on the right side of the bearing outer ring. Under the guidance of the horn ring's tapered guide surface, the movement direction of the bearing inner ring is gradually corrected, ensuring that it is accurately aligned with the outside of the equipment shaft in one go. This significantly improves installation efficiency and avoids hard contact between the equipment shaft and the bearing inner ring, effectively reducing the risk of scratches.

[0013] Secondly, the number of turns of the set screw is limited by two sets of control boards to avoid excessive compression and damage to the shaft surface of the equipment. The outer end of the set screw is inserted with a silicone block and covered with a silicone sleeve, which can effectively prevent water or oil stains from entering the hexagonal spline at the end and ensure smooth subsequent maintenance and disassembly.

[0014] This invention uses an external collar, a limiting ring, and a horn ring to ensure that the inner ring of the bearing can be precisely aligned with the outer side of the equipment shaft, while avoiding the risk of scratches caused by hard contact. Two sets of control boards limit the excessive compression of the set screws, which can damage the surface of the equipment shaft. The silicone sleeve effectively prevents the hexagonal spline from rusting due to water or oil, thus improving installation accuracy and efficiency and extending the service life of the equipment.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] Example 1: As shown in the attached document Figure 1 To be continued Figure 5 As shown: This utility model provides an outer spherical ball bearing with set screws, including an outer ring 1, an inner ring 2, a sealing cap 3, a set screw 4, a collar 5, a connecting box 6, a fixing box 7, and a guide assembly; the inner ring 2 is disposed inside the outer ring 1; two sealing caps 3 are provided, and the two sealing caps 3 are respectively fixedly connected to the left and right sides of the outer ring 1; two set screws 4 are provided, and the two set screws 4 are distributedly threaded to the left end of the inner ring 2; the collar 5 is sleeved on the outer side of the right end of the inner ring 2; the connecting box 6 is fixedly connected to the bottom of the collar 5; the fixing box 7 is fixedly connected to the bottom of the connecting box 6; the guide assembly is disposed on the right side of the outer ring 1.

[0024] The guide assembly also includes: a fixed spring 9, a connecting block 10, and a connecting groove 1001; the top of the fixed spring 9 is fixedly connected to the bottom of the top of the sliding rod 8, and the bottom of the fixed spring 9 is fixedly connected to the inside of the fixed box 7; the connecting block 10 is fixedly connected to the bottom right side of the sealing cover 3 on the right side; the connecting groove 1001 is opened inside the connecting block 10.

[0025] The guide assembly also includes a limiting ring 11 and a horn ring 12; the limiting ring 11 is fixedly connected to the right side of the collar 5, and the left end face of the limiting ring 11 is in contact with the right end face of the bearing inner ring 2; the horn ring 12 is fixedly connected to the right side of the limiting ring 11.

[0026] The specific usage and function of this embodiment: Before fitting the inner ring 2 of the bearing onto the outer side of the equipment shaft, in some underground equipment, compact motors, automobile chassis components, etc., if it is difficult to manually align the inner ring 2 of the bearing and the equipment shaft, the lower end of the sliding rod 8 can be pulled down to drive the sliding pin 801 to move downwards synchronously. Then, the collar 5 is fitted onto the outer side of the right end of the inner ring 2 of the bearing, and the connecting box 6 is fitted onto the outer side of the connecting block 10. When the left end face of the limiting ring 11 is in contact with the right end face of the inner ring 2 of the bearing, the sliding rod 8 is released. Under the rebound action of the fixed spring 9, the sliding rod 8 drives the sliding pin to move downwards. Pin 801 moves upward and inserts into connecting groove 1001, completing the assembly. The collar 5, limiting ring 11, and horn ring 12 are all made of plastic. The inner diameter of the limiting ring 11 is equal to the inner diameter of the bearing inner ring 2. By first placing the horn ring 12 on the outside of the equipment shaft and gradually moving it to the right, the tapered guide surface of the horn ring 12 guides the movement direction of the bearing inner ring 2. The movement direction of the bearing inner ring 2 is gradually corrected, ensuring that it is accurately aligned with the outside of the equipment shaft in one go. This significantly improves the installation efficiency and avoids direct hard contact between the equipment shaft and the bearing inner ring 2, reducing the risk of scratches.
