Description

Technical Field

[0001] This utility model belongs to the field of mechanical assembly technology, specifically relating to an auxiliary tool for the installation of bearings or couplings, which is particularly suitable for the safe and efficient installation of large bearings in high-temperature environments. Background Technology

[0002] In the field of mechanical assembly, the installation of bearings and couplings is one of the core processes, and its accuracy directly affects the operational stability and lifespan of the equipment. Currently, common installation methods mainly rely on manual operation: workers must wear heat-resistant gloves and manually adjust the heated bearings or couplings to align with the shaft. However, this traditional method has the following significant drawbacks:

[0003] 1. Significant safety hazards: The surface temperature of the bearing is extremely high after heating, usually exceeding 100°C. Even with protective equipment, there is still a risk of burns. During manual handling or adjustment, heavy bearings are prone to slipping, which may cause personal injury or equipment damage.

[0004] 2. Low centering accuracy and poor efficiency: Manual adjustment relies on experience, especially for large or precision bearings. The outer ring and cage are prone to misalignment, requiring multiple trial installations to achieve centering, which is time-consuming and labor-intensive. Traditional clamps such as simple chucks lack flexible adaptability, making it difficult to be compatible with bearings of different specifications, and they are also prone to scratching the bearing surface. Utility Model Content

[0005] The purpose of this utility model is to provide a bearing installation auxiliary tool.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A bearing installation auxiliary tool includes two clamping mechanisms, and a connecting mechanism is provided between the two clamping mechanisms.

[0008] The clamping mechanism includes a handle, a support rod, a baffle, and an arc plate. The handle is connected to one end of the support rod, and the other end of the support rod is connected to the baffle. The baffle is provided with an arc plate.

[0009] The connecting mechanism includes a connecting rod and a hinge. One end of the connecting rod is rotatably connected to the handle, and the other end of the connecting rod is hinged to another connecting rod via the hinge.

[0010] Furthermore, the arc-shaped plates on the two clamping mechanisms are arranged opposite to each other, the arc of the arc plate is the same as the arc of the outer ring of the bearing, and one side of the arc-shaped plate opening is attached to the outer ring of the bearing.

[0011] Furthermore, the arc-shaped plate is provided with a connecting part, and there are circumferential arms on the left and right sides of the connecting part. The connecting part is fixedly connected to the baffle plate, the circumferential arms extend out of the baffle plate, and there is a gap between them.

[0012] Furthermore, the baffle is arranged in a horizontal direction, and the upper surface of the baffle is attached to the bearing end face.

[0013] Furthermore, there are two connecting rods, which together with the two support rods form a W-shaped structure.

[0014] Furthermore, the connecting mechanism also includes a hanging ring and a spring, with a hanging ring on each of the two connecting rods and a spring connecting the two hanging rings.

[0015] Furthermore, one connecting rod is rotatably connected to the front side of the handle, and the other connecting rod is rotatably connected to the rear side of the handle, forming a scissor structure with the two connecting rods.

[0016] Furthermore, the clamping mechanism is also provided with a limiting mechanism, which includes a limiting hole and a limiting rod. A limiting hole is provided on one side of the support rod, and a limiting rod is provided at the same length position on the other side of the support rod. The limiting rod is horizontally set and passes through the limiting hole, and the limiting rod is slidably connected to the limiting hole.

[0017] Furthermore, the clamping mechanism and the connecting mechanism are made of stainless steel, and a rubber pad is provided on one side of the arc-shaped plate opening.

[0018] Furthermore, the curvature of the circumferential arm is the same as that of the outer ring of the bearing, and the side of the circumferential arm facing the opening of the arc plate is attached to the outer ring of the bearing.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. High-efficiency clamping and strong versatility: Through the arc design of the arc plate and its precise matching with the outer ring of the bearing, combined with the bottom support of the baffle and the elastic contraction force of the spring, high-precision clamping of bearings or couplings to shafts can be achieved quickly.

[0021] 2. Significantly improved safety performance: The coordinated design of the handle and rubber pads eliminates the need for operators to directly contact the high-temperature bearings, effectively avoiding the risk of burns; the rubber pads provide greater friction, making the overall clamping structure more stable and reducing the risk of accidental injury and equipment damage caused by bearing slippage or displacement.

[0022] 3. Simple structure and low cost: The tool is made of common metal materials (such as stainless steel) and rubber, requiring no complicated processing technology and low manufacturing cost; the components are fixed by welding or threaded connection, making assembly convenient and easy to promote and use.

[0023] 4. Protect bearings and extend their lifespan: The high-temperature rubber lining on the inner side of the arc plate prevents scratches on the outer ring surface of the bearing during installation, reduces damage caused by friction, and extends the bearing's service life; the baffle and the arc plate work together to precisely limit the cage displacement and avoid installation errors caused by misalignment.

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figure 1-4 As shown, a bearing installation auxiliary tool includes a clamping mechanism, two clamping mechanisms are provided, and a connecting mechanism is provided between the two clamping mechanisms. The clamping mechanism and the connecting mechanism are made of stainless steel.

[0033] The clamping mechanism includes a handle 1, a support rod 2, a baffle 3, and an arc plate 4. The handle 1 is connected to one end of the support rod 2, and the other end of the support rod 2 is connected to the baffle 3. The baffle 3 is set in the horizontal direction, and the upper surface of the baffle 3 is in contact with the bearing end face to restrict the axial displacement of the bearing. The baffle 3 is equipped with an arc-shaped plate 4, with two arc-shaped plates having openings 401 facing each other. The curvature of the arc-shaped plate 4 is the same as that of the outer ring of the bearing. One side of the arc-shaped plate opening 401 is attached to the outer ring of the bearing. The arc-shaped plate 4 has a connecting part 402, and there are circumferential arms 403 on both sides of the connecting part 402. The connecting part 402 is fixedly connected to the baffle 3. The circumferential arms 403 extend out of the baffle 3, leaving a gap between them to facilitate checking the bearing clamping status through the gap and to reduce the overall weight of the clamping mechanism. The curvature of the circumferential arms 403 is the same as that of the outer ring of the bearing. The side of the circumferential arms 403 facing the arc-shaped plate opening 401 is attached to the outer ring of the bearing, so that the arc-shaped plate 4 can firmly clamp the bearing to be installed. The arc-shaped plate 4 and the baffle 3 together form a barrel-shaped clamping and supporting structure. The arc-shaped plate 4 clamps the side of the bearing, and the baffle 3 abuts against the bottom surface of the bearing to prevent the bearing from shifting and falling off. A rubber gasket is provided on one side of the arc-shaped plate opening 401. The rubber gasket is made of high-temperature resistant material, which can effectively prevent the bearing outer ring from being scratched during installation, and can also prevent the heated bearing from burning the staff.

[0034] The connecting mechanism includes connecting rods 5 and hinges 7. Two connecting rods 5 are provided; one end of each connecting rod 5 is rotatably connected to the handle 1 via a rivet, and the other end is hinged to another connecting rod 5 via the hinge 7. The two connecting rods 5 and the two support rods 2 form a W-shaped structure to prevent horizontal displacement and enhance the stability of the clamping mechanism. One connecting rod 5 is rotatably connected to the front side of the handle 1, and the other connecting rod 5 is rotatably connected to the rear side of the handle 1. The two connecting rods 5 form a scissor structure to prevent lateral displacement perpendicular to the extension / retraction direction, further enhancing the overall stability of the device. The connecting mechanism also includes hanging rings 8 and springs 6. Each connecting rod 5 is provided with a hanging ring 8, and a spring 6 connects the two hanging rings 8.

[0035] In use, the operator holds handle 1 and places the arc-shaped plates 4 of the two clamping mechanisms against both sides of the outer ring of the bearing. The elastic tension of the spring 6 causes the connecting rod 5 to automatically tighten, driving the clamping mechanism to stably clamp the bearing and prevent slippage. The baffle 3 fits tightly against the lower end face of the bearing, limiting the axial displacement of the bearing. The high-temperature resistant rubber lining of the arc-shaped plate 4 isolates the bearing heat, prevents scratching the bearing surface, and increases friction to prevent the bearing from falling off. After clamping, the bearing is moved to the shaft end, and the tool position is adjusted to initially align the bearing with the shaft. The bearing angle is finely adjusted by using handle 1. The cooperation of the arc-shaped plate 4 and the stop ensures that the bearing cage does not shift. The bearing is slowly lowered to the shaft end, and the elastic contraction force of the spring 6 assists in precise alignment of the bearing with the shaft, completing the installation.

[0036] Example 2

[0037] like Figure 5 As shown, based on Embodiment 1, the clamping mechanism is further provided with a limiting mechanism, which includes a limiting hole 9 and a limiting rod 10. A limiting hole 9 is provided on one side of the support rod 2, and a limiting rod 10 is provided at the same length position on the other side of the support rod 2. The limiting rod 10 is horizontally positioned and passes through the limiting hole 9, and is slidably connected to the limiting hole 9. The limiting mechanism ensures that the two support rods 2 remain parallel and the two baffles 3 remain horizontal, resulting in greater stability when clamping the bearing.

[0038] This utility model discloses a bearing installation auxiliary tool that effectively solves the problems of safety hazards, low efficiency, and insufficient alignment accuracy in traditional bearing installation through the synergistic effect of an innovative W-shaped frame mechanism, elastic spring 6 design, and high-temperature resistant rubber lining. This tool is particularly suitable for the installation of high-temperature, heavy-duty, or precision bearings, significantly improving assembly efficiency and extending bearing life.
