Description

Technical Field

[0001] This utility model relates to the field of mechanical installation technology, and in particular to an auxiliary installation device for an oil seal. Background Technology

[0002] In the fields of machinery manufacturing and equipment maintenance, bearings, as a key component, are widely used in various rotating machinery, playing a vital role in supporting the machine and reducing friction. With the continuous development of industrial technology, the requirements for bearing performance and installation quality are becoming increasingly stringent. The installation of bearing oil seals is a crucial step in ensuring the normal operation of bearings and preventing lubricating oil leakage; its installation quality directly affects the reliability and service life of equipment. Efficient and accurate oil seal installation technology is of great significance for improving production efficiency and reducing equipment maintenance costs. Good oil seal installation technology can effectively enhance the overall performance of equipment and provide strong support for the stable operation of industrial production.

[0003] In traditional bearing oil seal installation, for cases with relatively short steps, the oil seal is typically installed manually. Workers rely on experience and manual operation to slowly insert the oil seal into the appropriate position on the bearing. However, this method has many inconveniences in practice. In addition, some simple auxiliary tools, such as ordinary sleeves or clamps, are used in some cases, but these tools have poor versatility and adaptability, and cannot be well optimized for the specific needs of installing bearing oil seals with short steps.

[0004] Existing technologies have significant shortcomings in addressing the installation of oil seals for short-step bearings. When the bearing step is relatively short, traditional installation methods cannot effectively guide the oil seal, easily leading to lip flaring at the inner ring edge. This not only affects the efficient installation of the oil seal but also easily damages it, reducing its service life and sealing performance. Manual installation is inefficient due to inaccuracies and high labor intensity, making it difficult to guarantee installation precision and quality. Utility Model Content

[0023] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0024] This utility model discloses an auxiliary installation device for oil seals, such as... Figure 1 and Figure 2 As shown, the assembly includes a bearing body 1, a spindle 2, an auxiliary sleeve 3, a reducing structure 4, and a clamping fixture 5. The auxiliary sleeve 3 is fitted onto the spindle 2 of the bearing body 1, the reducing structure 4 is mounted on the auxiliary sleeve 3, and the clamping fixture 5 is located on the outside of the auxiliary sleeve 3. It can radially clamp the oil seal and press it down simultaneously, thus reducing the difficulty of installing the oil seal at short steps, minimizing the possibility of flanges during installation, and improving assembly efficiency. This is because the auxiliary sleeve 3 can temporarily lengthen the step, the reducing structure 4 can guide the oil seal to be quickly installed, and the clamping fixture 5 can accurately limit and guide the oil seal installation.

[0025] Specifically, the bearing body 1 is the fundamental component of the entire device, providing a mounting and support location for components such as the spindle 2. The bearing body 1 is typically made of metallic materials, such as carbon steel or alloy steel, possessing high strength and wear resistance to ensure stable and reliable operation during long-term use. The shape and structure of the bearing body 1 are designed according to specific application scenarios and requirements, generally featuring a ring structure with internal space to accommodate other components.

[0026] The mandrel 2, housed within the bearing body 1, is a crucial component connecting the bearing body 1 to other parts. The mandrel 2 transmits power and supports rotating components. It is typically made of high-strength metal materials, such as stainless steel or chromium-molybdenum steel, to ensure sufficient strength and rigidity. The mandrel 2 is generally cylindrical in shape, with a precision-machined surface to ensure accurate fit with other components. In this embodiment, the mandrel 2 has an axially extending limiting step 6 at the oil seal mounting area. The limiting step 6 defines the installation position of the oil seal, ensuring it can be accurately installed in the designated location. The height and width of the limiting step 6 are designed according to the size of the oil seal and installation requirements. Generally, the height of the limiting step 6 should be slightly less than the thickness of the oil seal to ensure smooth insertion of the oil seal.

[0027] The auxiliary sleeve 3 is fitted onto the mandrel 2 and connected to it with a clearance fit. The inner cavity of the auxiliary sleeve 3 basically matches the mandrel 2, and its outer ring matches the outer wall of the step. Its function is to temporarily lengthen the step, reducing the difficulty of installing the oil seal at short steps. The auxiliary sleeve 3 is usually made of lightweight materials such as plastic or aluminum alloy, which reduces the weight of the entire device and lowers costs. The surface of the auxiliary sleeve 3 is smoothed to reduce friction with the oil seal, facilitating its insertion. In practical applications, the auxiliary sleeve 3 can also be replaced by other components with similar functions, such as rubber sleeves or silicone sleeves.

[0028] A reducing structure 4 is located at the top of the auxiliary sleeve 3 and features a tapered guide section whose inner diameter gradually increases from the top to the bottom. The function of the reducing structure 4 is to guide the rapid insertion of the oil seal, making it easier for the oil seal to fit into the auxiliary sleeve 3. The angle and length of the tapered guide section of the reducing structure 4 are designed according to the size and shape of the oil seal. Generally, the angle of the tapered guide section should be between 30° and 60°, and the length should be appropriately adjusted according to the outer diameter of the oil seal and the outer diameter of the auxiliary sleeve 3.

[0029] The clamping fixture 5 includes a cylinder 511 assembly 51 disposed outside the auxiliary sleeve 3 and a clamping member 52 interconnected with the cylinder 511 assembly 51. The cylinder 511 assembly 51 includes multiple annularly designed cylinders 511, and a supporting workpiece 7 is disposed outside the cylinder 511 assembly 51 to fix the multiple cylinders 511. The function of the cylinder 511 assembly 51 is to drive the clamping member 52 to clamp the oil seal, providing a stable clamping force to ensure that the oil seal does not shift during installation. The cylinders 511 are typically made of materials such as aluminum alloy or stainless steel, possessing high strength and corrosion resistance. The supporting workpiece 7 serves to fix the cylinders 511, ensuring their stability and reliability; it is typically made of metallic materials such as carbon steel or alloy steel.

[0030] A lifting assembly 8 is provided on the top of the clamping fixture 5. The lifting assembly 8 is fixedly connected to the supporting workpiece 7. The lifting assembly 8 drives the clamping fixture to move radially along the auxiliary sleeve 3. The lifting assembly 8 can be an electric screw jack or other equipment, which has the advantages of smooth lifting and high precision. Driven by the lifting assembly 8, the clamping fixture 5 can accurately press the oil seal down to the installation position.

[0031] The clamping member 52 has an arc-shaped claw 521 structure, and the inner surface of the arc-shaped claw 521 is provided with an elastic anti-slip layer. The function of the clamping member 52 is to directly clamp the oil seal, and the function of the elastic anti-slip layer is to increase the friction between the clamping member 52 and the oil seal, preventing the oil seal from slipping during clamping. The elastic anti-slip layer is usually made of materials such as rubber or silicone, which have good elasticity and anti-slip properties. The shape and size of the arc-shaped claw 521 are designed according to the outer diameter of the oil seal. Generally speaking, the curvature of the arc-shaped claw 521 should match the outer diameter of the oil seal to ensure that the oil seal can be tightly clamped.

[0032] The implementation principle of this embodiment is as follows: The auxiliary installation device for the oil seal, by setting an auxiliary sleeve 3, changes the short step state of the bearing oil seal installation area, reducing the difficulty of installing the oil seal at the short step. The variable diameter structure 4 guides the oil seal to be quickly inserted into the auxiliary sleeve 3, and the clamping fixture 5 clamps the oil seal from the side and presses it down simultaneously, ensuring that the oil seal can be correctly limited and guided when inserted, reducing the probability of the inner ring lip of the oil seal turning over during installation. Compared with the traditional installation method, this device improves assembly efficiency, reduces manpower consumption, improves assembly accuracy, and reduces time consumption, making a significant improvement and contribution to the existing technology.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
