Description

Technical Field

[0001] This utility model relates to the field of mechanical parts, and in particular to a bearing housing for mechanical parts. Background Technology

[0002] Bearing housings are core components in mechanical systems that support bearings. Their function is to provide a stable mounting base for the bearings while isolating them from external environmental interference. As an important structural component that bears rotating parts, bearing housings must be made of high-strength, wear-resistant materials to ensure they can effectively withstand the multi-directional loads generated by mechanical operation under complex working conditions and possess corrosion resistance. Their structural design must consider bearing type matching, reasonable load distribution, and ease of maintenance, ensuring both precise alignment of the bearing and the shaft system and long-term reliability and stability.

[0003] The traditional installation process between bearings and bearing housings relies on specialized tools and manual operation. The installation process of bearing housings has significant technical bottlenecks. Installers need to use special tooling to press the bearing into the housing. However, deviations in pressing force control can easily lead to damage to the bearing raceway. The entire operation is cumbersome and has a low error tolerance, which increases the time cost of equipment debugging. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of low efficiency in the installation process between bearings and bearing housings in the existing technology, and to propose a bearing housing for mechanical parts.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution:

[0006] A bearing housing for mechanical parts includes a bearing housing shell, and a movable frame is movably inserted into the bearing housing shell. The movable frame is composed of four symmetrically distributed rectangular blocks and two circular rings symmetrically connected between the rectangular blocks. The inner circumferential surface of the circular rings forms a bearing mounting and positioning surface.

[0007] Preferably, concave blocks are fixed at both ends of the rectangular block, the openings of the concave blocks face the center, and a sealing element is fitted inside the concave blocks.

[0008] Preferably, the movable frame further includes a lubricant, which includes a collection groove formed on the surface of the uppermost rectangular block and an oil outlet groove formed inside the lowermost rectangular block.

[0009] Preferably, multiple guide grooves are provided on both sides of the collection groove, and the guide grooves are located on both sides of the circular ring.

[0010] Preferably, an oil inlet pipe is fixedly provided above the bearing housing, with the lower end of the oil inlet pipe facing the middle of the collection tank.

[0011] Preferably, both the oil inlet pipe and the oil outlet end of the oil outlet groove are threaded with sealing plugs.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] In the description of this specification, the references to terms such as "embodiment," "one embodiment," "some implementations," "exemplary," and "one implementation," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or implementation of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0026] Example: This example provides a bearing housing for mechanical parts, see [link / reference]. Figure 1-4 Specifically, the bearing housing includes a bearing housing shell 1, within which a movable frame 11 is movably inserted. The movable frame 11 consists of four symmetrically distributed rectangular blocks 111 and two circular rings 112 symmetrically connected between the rectangular blocks 111. The inner circumferential surface of the circular rings 112 forms the bearing mounting and positioning surface. The movable frame 11 is composed of four rectangular blocks 111, with two circular rings 112 installed in the middle of the four rectangular blocks 111. There is a certain distance between the circular rings 112 and a certain distance between the circular rings 112 and the bearing housing shell 1. When installing the bearing, the movable frame 11 is first moved out of the bearing housing shell 1, then the bearing is installed between the circular rings 112, and then the movable frame 11 is moved into the bearing housing shell 1 and fixed. This allows for quick bearing installation without the need for specific tools to position the bearing before pressing it into the bearing housing using a pressure device, thus improving installation efficiency and quality.

[0027] In the specific implementation process, such as Figure 2 and Figure 3As shown, both ends of the rectangular block 111 are fixed with concave blocks 2, the openings of the concave blocks 2 face the center, and a seal 21 is clamped inside the concave blocks 2. By adding concave blocks 2 at the ends of the rectangular block 111, the seal 21 is clamped inside the concave blocks 2, so that the seal 21 is connected to the moving frame 11, and the seal 21 and the bearing are installed and disassembled synchronously. Since there is lubricating oil between the bearing and the bearing housing, the seal 21 blocks the lubricating oil inside the bearing housing housing 1.

[0028] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the movable frame 11 also includes a lubricating component 3, which includes a collection groove 31 on the surface of the uppermost rectangular block 111 and an oil outlet groove 32 inside the lowermost rectangular block 111. The collection groove 31 is provided on a rectangular block 111 to hold lubricating oil. The lubricating oil is distributed between the bearing housing and the bearing through the collection groove 31. The lowermost rectangular block 111 is provided with an oil outlet groove 32. The inlet end of the oil outlet groove 32 is located at the gap of the circular ring 112. The oil enters the interior of the rectangular block 111 through the inlet end and is discharged from one end of the rectangular block 111.

[0029] In the specific implementation process, such as Figure 2 and Figure 3 As shown, multiple guide grooves 4 are provided on both sides of the collection tank 31. The guide grooves 4 are located on both sides of the circular ring 112. The guide grooves 4 guide the lubricating oil in the collection tank 31 to the gap of the circular ring 112, so that the lubricating oil can lubricate the bearing inside the gap.

[0030] In the specific implementation process, such as Figure 2 and Figure 3 As shown, an oil inlet pipe 5 is fixedly installed on the upper part of the bearing housing 1, and the lower end of the oil inlet pipe 5 is directly opposite the middle of the collection tank 31; lubricating oil is added to the collection tank 31 from the outside through the oil inlet pipe 5, which facilitates the addition of lubricating oil to the inside of the bearing housing.

[0031] In the specific implementation process, such as Figure 2 and Figure 4 As shown, both the oil inlet pipe 5 and the oil outlet groove 32 are threaded with sealing plugs 6 at their oil outlet ends; the sealing plugs 6 are used to seal the oil inlet pipe 5 and the oil outlet groove 32.

[0032] In the specific implementation process, such as Figure 2 and Figure 3 As shown, multiple mounting grooves 7 are symmetrically provided on the bearing housing shell 1 and the circular ring 112. The mounting groove 7 is threaded with a positioning screw 71. The positioning screw 71 passes through the bearing housing shell 1 and the circular ring 112, and its end fits against the outer wall of the bearing, thereby fixing the bearing housing, the moving frame 11 and the bearing position.

[0033] In the specific implementation process, such as Figure 1 and Figure 2 As shown, four connecting grooves 8 are symmetrically opened on the inner wall of the bearing housing 1. The rectangular blocks 111 are all in contact with the inner wall of the connecting grooves 8 to limit the movement of the moving frame 11, so as to facilitate the installation of the moving frame 11 into the bearing housing 1.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
