Description

Technical Field

[0001] This utility model relates to the field of bearing housing assembly technology, specifically to a bearing housing through-cover oil seal installation fixture. Background Technology

[0002] A bearing housing is a device used in mechanical equipment to secure and support bearings. It provides a robust mounting position for the bearing and ensures stable operation. An oil seal on the bearing housing cover is a common type of seal used to protect the bearing from external contaminants such as dust and moisture, while preventing lubricants (such as oil or grease) from leaking out of the bearing. Skeleton oil seals are typically made of rubber and have a metal or plastic skeleton as a support structure to maintain their shape and help seal the oil seal within the bearing housing.

[0003] Currently, oil seals are mostly installed manually. Workers need to place the oil seal on the oil seal mounting ring groove of the bearing housing cover, then place one end of an iron rod against the oil seal, and use a small hammer to tap the iron rod to press the oil seal into the oil seal mounting ring groove little by little along the edge of the skeleton oil seal. This method is inefficient and requires workers to use both hands, which can easily injure fingers during installation and poses a safety hazard. Utility Model Content

[0004] The purpose of this utility model is to provide a bearing housing through-cover oil seal installation fixture, which can install the skeleton oil seal into the oil seal installation ring groove of the bearing housing without having to press it in little by little by hammering, thereby improving installation efficiency. It can also be operated with one hand, avoiding finger injuries during installation and improving installation safety.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a bearing housing cover oil seal installation fixture, comprising:

[0006] A circular plate, wherein the diameter of the circular plate is larger than the diameter of the oil seal mounting annular groove on the bearing housing;

[0007] The column is disposed at the upper end of the circular plate;

[0008] A counterweight is slidably connected to the column and its lower end can contact the circular plate.

[0009] A further improvement of this utility model is that the counterweight is a cylinder with a sliding hole coaxially extending through it, and the cylinder is slidably connected to the column through the sliding hole.

[0010] A further improvement of this utility model is that the lower end of the circular plate is provided with a circular ring corresponding to the oil seal mounting groove.

[0011] A further improvement of this invention is that the thickness of the ring is greater than the width of the oil seal mounting ring groove.

[0012] A further improvement of this utility model is that the circular plate has a threaded opening at its center, and the column is threadedly connected to the circular plate.

[0013] A further improvement of this utility model is that a buffer washer is provided on the lower end face of the ring.

[0014] A further improvement of this utility model is that the diameter of the counterweight is less than 10cm.

[0015] A further improvement of this utility model is that the outer periphery of the counterweight is provided with several grooves to increase friction.

[0016] A further improvement of this utility model is that the circular plate, column and counterweight are all metal parts.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention utilizes a circular plate in conjunction with a counterweight. After the counterweight is raised along the column, its gravitational potential energy is converted into pressure on the oil seal, which can press the skeleton oil seal into the oil seal mounting ring groove of the bearing seat. Unlike the prior art, it does not require hammering to press it in little by little, thus achieving rapid installation and improving installation efficiency.

[0019] The installation of the oil seal using this invention can be done with one hand. Simply raise the counterweight and keep your hand at a distance from the column. The counterweight moves only along the column, ensuring high safety. Compared to the existing technology that uses a small hammer and iron rod, this invention effectively avoids finger injuries during installation and improves installation safety.

[0020] This invention improves the pressing effect by setting a ring at the lower end of the circular plate, which contacts the oil seal. Compared with the circular plate contacting the oil seal directly, this increases the pressure.

[0021] This invention allows for the uniform application of pressure across the entire circumference of the oil seal during installation, preventing deformation caused by uneven force during hammering and effectively improving assembly results. Attached Figure Description

[0025] In the diagram, 1-circular plate, 2-column, 3-counterweight, 4-ring, 5-pattern. Detailed Implementation

[0026] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. Example

[0027] Combination Figures 1-3 It can be seen that a bearing housing through-cover oil seal installation fixture includes:

[0028] Circular plate 1, the diameter of circular plate 1 is larger than the diameter of the oil seal mounting ring groove on the bearing housing;

[0029] Column 2 is installed on the upper end of circular plate 1;

[0030] Counterweight 3 is slidably connected to column 2 and its lower end can contact circular plate 1.

[0031] The counterweight 3 is a cylinder with a sliding hole running through it coaxially. The cylinder is slidably connected to the column 2 through the sliding hole.

[0032] The lower end of the circular plate 1 is provided with a circular ring 4 corresponding to the oil seal mounting groove.

[0033] The thickness of ring 4 is greater than the groove width of the oil seal mounting ring groove. The thickness of ring 4 is the distance from the inner diameter to the outer diameter of the ring.

[0034] Depending on the bearing housing structure, some bearing housing covers may have an outer annular structure such as an assembly ring on the outer circumference of the oil seal mounting ring groove. In this case, the diameter of the circular plate 1 must be smaller than the diameter of this type of annular structure to avoid affecting the contact with the oil seal.

[0035] The circular plate 1 has a threaded hole at its center, and the column 2 is threaded onto the circular plate 1. The column 2 and the circular plate 1 are detachably connected, the connection is stable, and it is easy to assemble.

[0036] Optionally, a buffer washer is provided on the lower end face of the ring 4. The buffer washer provides cushioning and reduces wear with the bearing housing.

[0037] The diameter of counterweight 3 is less than 10cm. This is to make it easier to pick up and lift by hand.

[0038] The outer periphery of the counterweight 3 is provided with several textures 5 to increase friction, prevent slippage when held, and improve safety. Preferably, the textures 5 are one of the following: protrusions, grooves, or annular protrusions on the outer periphery of the counterweight 3.

[0039] The circular plate 1, the column 2, and the counterweight 3 are all metal parts. Preferably, all three are made of cast iron.

[0040] The working principle of the bearing housing through-cover oil seal installation fixture provided by the utility model is as follows: During operation, the skeleton oil seal is aligned with the oil seal installation ring groove of the bearing housing, the ring 4 is placed on the oil seal, and its position is adjusted to ensure that the upper end face of the oil seal is completely disengaged from the ring 4. The counterweight 3 is lifted manually, and then released. The counterweight 3 falls down along the column 2 and strikes the circular plate, converting its gravitational potential energy into pressure on the oil seal. After being pressed, the oil seal deforms and is installed into the oil seal installation ring groove (it can be struck repeatedly), thus completing the installation of the oil seal.

[0041] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
